摘要： A casting system for the processing of casting resin. From evacuatable storage containers casting resin components are fed to pump cylinders. The movement of the pump cylinders is synchronized through a mechanical connection. The drive of the pistons in the pump cylinders occurs by means of driving fluids which approximately are under the same pressure as the resin components. Leakages across the pistons are avoided due to the pressure equality on both sides of the pistons even when, in consideration of abrasive filler materials, relatively large gaps must be provided between the pistons and their cylinders.

摘要： A pump for discharging a predetermined quantity of fluid. The pump housing contains a reciprocating pumping member, which is preferably driven in a forward stroke by mechanical, hydraulic or pneumatic means under the control of a solenoid which, when energized, causes the pumping member to take the forward stroke, the length of which corresponds to the predetermined quantity of fluid to be delivered by the pump. The solenoid remains energized until the forward stroke is completed, at which time it is deenergized. The stroke length of the pumping member, and hence the amount of fluid delivered by the pump, is adjustable. The driving force for the return stroke of the pumping member is preferably accomplished by means of a spring which is loaded during the forward stroke, the force of the loaded spring being overcome by the solenoid as long as the solenoid is energized, or by hydraulic or pneumatic means controlled by a conventional distribution member under the influence of the solenoid.

摘要： A hot water system comprising a hot water heater and conduit means coupled to feedwater under pressure for conducting water to and from the hot water heater. The system also includes an injector pump and a reverse osmosis module which has an inlet port, a product water port and a brine outlet port. The injector pump has an inlet coupled to the feedwater under pressure, a brine port coupled to the brine outlet port of the reverse osmosis module and a discharge port coupled to the conduit means. The injector pump includes a first valve operated by the injector pump for opening and closing the inlet of the injector pump. A second valve is provided between the reverse osmosis module and the brine port. The injector pump provides water to the inlet port of the reverse osmosis module and increases the pressure of the brine at the discharge port of the injector pump to greater than the pressure of the feedwater so that the brine can be injected into the hot water system.

摘要： An intensifier for delivering ultra high pressure water to a cutting head of a water jet cutting apparatus. The intensifier has a power piston and cylinder assembly connected to piston members extended into pumping chambers in housing located at opposite ends of the piston and cylinder assembly. Inlet poppet valves located in the pumping chambers control the flow of water from inlet passages into the pumping chambers. Outlet poppet valves allow ultra high pressure water to be pumped out of the pumping chamber into an accumulator fluidly connected to the cutting head. Hydraulic fluid under pressure is sequentially directed to opposite ends of the piston and cylinder assembly with a solenoid operated reversing valve. Limit switches operable in response to movement of the piston members control the reversing valve. Linear motion transfer mechanisms are moved with ramps on the piston members to actuate the limit switches to control the reciprocating action of the piston and cylinder assembly.
