摘要： A pressure washer device is provided that employs an unloader bypass valve that directs a selective amount of fluid via a small diameter bypass line back to a water storage tank. The small amount of fluid allows for the pump to remain working and introduces cooler water into a bypass circuit, thereby allowing the thermal relief valve to be omitted. The diameter of the bypass line is of such a diameter to prevent siphonage of the detergent associated with the pressure washer system into the water storage tank as well.

摘要： A high pressure hot water acid washer is towed to a site on a trailer. A chemical tank and gasoline and diesel fuel tanks are filled. A water supply hose is connected to a water tank. A power cord is connected to a power source. A float valve controls the filling of the water tank. Water flows from the water tank through a Y-type filter to a water pump. A drain withdraws water directly from the water pump. The water pump and a compressor are driven with an engine. Pressurized water flows through a flow switch to a heat exchanger. Upon water flow, the flow switch completes a power circuit to operate a fuel pump with an electric motor. Fuel is pumped from the fuel tank and is atomized and sprayed into the heat exchanger. An ignition coil ignites the fuel. The power circuit is interrupted upon sensing a high temperature in a pressurized water delivery line from the heat exchanger. Pressure of pressurized hot water in the delivery line is controlled with a hot water pressure relief valve. Hot water flows out through a high pressure hot water hose and nozzle. The chemical tank is pressurized with air from the compressor, and chemical flows from the chemical tank. Rate of flow of chemical is controlled with a needle valve. Opening the chemical line with ball valve releases chemical to the fast hot water stream from the nozzle.

摘要： A pressure washer for delivering liquid under high pressure has an inlet conduit connected to a liquid supply, an outlet conduit connected to a spray nozzle with a valve which is selectively openable for spraying liquid and a plurality of piston operated pumping cylinders connected in parallel between the inlet conduit and the outlet conduit. A bypass conduit recirculates liquid from the outlet to the inlet conduit. A valve in the bypass conduit selectively permits leakage from the outlet conduit when the spray nozzle valve is open and opens communication between the outlet conduit and the bypass conduit when the spray nozzle valve is closed and pressure builds up in the outlet conduit.

摘要： In a high-pressure cleaning apparatus with a high-pressure pump for a cleaning liquid connected on the suction side to a preliminary tank with a feed pipe for cleaning liquid and having in the pressure pipe a bypass pipe branching off from this pressure pipe and leading to the preliminary tank, and with an electromotor driving the high-pressure pump and having a coolant pipe through which cleaning liquid flows, in order to also ensure effective cooling of the electromotor in the recirculation mode without loss of coolant, it is proposed that the feed pipe to the preliminary tank have a greater conveying capacity than the coolant pipe and that the coolant pipe lead into the preliminary tank in which there is a means for limiting the filling level.

摘要： A pressure washer for delivering liquid under high pressure has an inlet conduit connected to a liquid supply, an outlet conduit connected to a spray nozzle with a valve which is selectively openable for spraying liquid and a plurality of piston operated pumping cylinders connected in parallel between the inlet conduit and the outlet conduit. A bypass conduit recirculates liquid from the outlet to the inlet conduit. A valve in the bypass conduit selectively permits leakage from the outlet conduit when the spray nozzle valve is open and opens communication between the outlet conduit and the bypass conduit when the spray nozzle valve is closed and pressure builds up in the outlet conduit. Each piston in a pumping cylinder is driven to reciprocate through its pumping cylinder. The piston also moves laterally because there is an eccentric connection between the piston and a common rotary pin for each of the pistons of each of the pumping cylinders. Appropriate valves direct liquid flow only from the inlet conduit through the pumping cylinders to the outlet conduit. Additional liquid may be supplied to and mixed with the liquid in the outlet conduit through a valve at a venturi connection in the outlet conduit. A pressure gauge connected with the outlet conduit measures pressure there.

摘要： This invention relates to a mobile system for washing vehicles which supplies water at high pressure through a discharge hose to a user-operated spray gun or wand. The mobile washing system contains means to receive water at low pressure from the municipal or domestic well water supply. There is an engine and pump that pressurizes the water received; an onboard sdelf regenerating water softening unit to remove impurities from the wash and rinse water so that washed vehicles may dry virtually spot-free without manual drying; reservoirs for storing a liquid cleaning agent and a liquid wax which can be introduced into the discharge stream under operator control to eliminate the need to manually apply soap or wax; and valves and controls to effectively operate the wash system. All components are mounted on a wheeled cart which can be easily rolled from vehicle to vehicle by the operator or rolled to a convenient washing location. The water softening system is such that is may be regenerated by the user as required, eliminating both the expense of returning the mineral tank to the manufacturer and the frequenct, lengthly periods of unavailability.

摘要： A mobile cleaning unit for providing high pressure cleaning and rinsing sprays, comprising a van-type vehicle with separate sources of water and cleaning and treating solutions. The sprays may be heated by a self-contained water heater with a fuel ignitor operated by low voltage direct current. The separate solutions are selected by a pressure switch sensitive to an increase in spray line pressure caused by stopping the spray by operation of a valve at the spray applicator. The pressure switch acts to sequentially open a supply valve for each solution in turn.

摘要： Apparatus is described which is adapted to analyze various operating conditions and characteristics of steam cleaners and pressure washer (e.g., of the type which heats water and forces it out of a nozzle under pressure). The test apparatus includes means for testing and analyzing operating characteristics and parameters such as inlet and outlet water temperature, water pump head pressure, coil outlet pressure, fuel pressure, water flow rate, voltage and electrical current draw, stack temperature, and hydrocarbon emissions. The test apparatus is useful in servicing pressure washers and in comparing the operation of one pressure washer to another pressure washer. The test apparatus is also very useful in detecting possible safety hazards existing in steam cleaners and pressure washer.

摘要： In operating high-pressure cleaning units, the outflow of the water discharged from the associated pump (6,8) may be temporarily interrupted. As the pump normally operates continuously, care must be taken to ensure that the water can then be returned in a bypass to the pump's suction side. This can be achieved by a bypass valve sensing a rising pressure in the said closing situation, thus opening for the bypass. Correspondingly, the bypass valve (36,44,32) senses a declining pressure when the discharge or ejection is resumed, thus causing a block to the bypass (40). However, a corresponding, declining pressure occurs when the pump is stopped, for which reason the bypass valve will block the bypass also in this condition. Thus, the result is that during the stopping process determined by the pump's inertia a substantial and dangerous pressure may build up in the discharge conduit (26) from the pump. The invention eliminates this pressure build-up by the bypass valve (36,44,32) being designed to respond to a pressure decline with such a time delay (via a constriction 60) that the pump with associated motor will be essentially fully stopped after switching off the motor, prior to the bypass being closed. In practice, it is without major significance that a slight delay also occurs in this way when reconnecting full operating pressure when reopening for the discharge from the cleaning unit.

摘要翻译： 在操作高压清洁单元时，从相关联的泵（6,8）排出的水的流出可能暂时中断。 当泵通常连续运行时，必须注意确保水可以旁路返回到泵的吸力侧。 这可以通过旁路阀来实现，该旁路阀感测所述关闭情况下的上升压力，从而为旁路打开。 相应地，旁路阀（36,44,32）在排放或喷射恢复时感测到下降的压力，从而导致对旁路（40）的阻挡。 然而，当泵停止时发生相应的下降的压力，因此在这种情况下旁路阀也将阻塞旁路。 因此，结果是在由泵的惯性确定的停止过程中，来自泵的排放导管（26）中可能积聚着相当大的危险的压力。 本发明消除了旁路阀（36,44,32）的这种压力积聚，该旁路阀被设计成响应压力下降，这样的时间延迟（经由收缩部60），相关电动机的泵将在 在旁路关闭之前关闭电机。 实际上，当重新打开清洁单元的排放时，在重新连接全部工作压力时，也会发生轻微的延迟。
