Abstract:
A pressure washer system includes a combustion engine having a power takeoff. The center of the power takeoff defines an axis of rotation. The pressure washer system further includes a centrifugal clutch coupled to the power takeoff. The clutch comprises a flywheel having a center of mass positioned along the axis of rotation. The pressure washer system also includes a water pump coupled to the clutch output shaft.
Abstract:
A garden hose spray system includes a water pump and a controller with a switch for engaging and disengaging the pump. The pump is used for boosting a water flow through the system. The controller is in communication with the pump, and directs the switch to engage the pump when the water flow exceeds a predetermined, non-zero threshold flow rate. In certain embodiments, the system further includes a variable outlet. The variable outlet is operable at a first flow setting for a flow rate greater than the threshold and a second flow setting for a non-zero flow rate less than the threshold.
Abstract:
A pressure washer includes a water pump and a pressure-sensitive member attached to the water pump. The pressure washer also includes a wire having a first end attached to the pressure-sensitive member. The pressure-sensitive member relays a change in water pressure within the pump through the wire. Additionally the pressure washer includes an engine having a governor spring attached to the wire. Movement of the wire changes a tension of the governor spring. The engine also has a throttle plate attached to the governor spring. The governor spring biases the throttle plate.
Abstract:
An accessory tray for a pressure washer. The accessory tray of some embodiments has an accessory supporting portion for supporting and/or storing accessories of the pressure washer. The accessory supporting portion has a concave surface, which allows the accessories to be supported substantially normal to the ground regardless of the relative angle between the accessory tray and the ground. Some embodiments also have a flexible cantilevered member positioned above a portion of the accessory tray to trap an accessory against the accessory tray. Some embodiments can have a hose hook that supports and stores a hose of the pressure washer. The hose hook has a concave shape to allow the hose to be supported substantially normal to the ground.
Abstract:
A pressure washer gun is connectable to a source of fluid. The pressure washer gun includes a housing that defines an interior and a flow path disposed substantially within the interior. The flow path includes an inlet in fluid communication with the source and an outlet. A valve at least partially defines a portion of the flow path and is movable between a closed position and an open position in which fluid travels from the inlet to the outlet. A user interface is movable between an actuated position in which the valve is open and a non-actuated position in which the valve is closed. A lock member is substantially disposed within the interior and is movable in a substantially arcuate path between a locked position in which the lock assembly inhibits movement of the user interface, and an unlocked position.
Abstract:
A nozzle for use with a sprayer, such as a spray gun for a pressure washer or a garden hose system, includes a body, which has an inlet for receiving a pressurized flow of water. The nozzle further includes first and second outlets, and first and second passages. The first and second outlets are formed in an end of the body. The first passage extends between the inlet and the first outlet, and the second passage extends between the inlet and the second outlet. The first and second passages are substantially straight and parallel to one another. During operation of the nozzle, the pressurized flow of water from the inlet is split, passes through the first and second passages, and exits the body from the first and second outlets.
Abstract:
A garden hose booster system includes a pump for pressurizing water, a motor connected to and designed to drive the pump, and a housing supporting the pump and the motor. The garden hose booster system further includes an inlet conduit, an outlet conduit, and a storage container. The inlet has a first garden hose coupling on an end thereof, and extends into the housing to direct the water to the pump. The outlet conduit has a second garden hose coupling on an end thereof, and extends out of the housing to direct the water from the pump. The storage container includes a bottom designed to be mounted to the top of the housing and a side wall extending upward from the bottom. The side wall and the bottom form an open volume within which a garden hose may be piled or coiled for storage thereof. The outlet conduit extends into the open volume of the storage container such that the garden hose stored in the storage container may be coupled to the second garden hose coupling and may receive a boosted water flow during operation of the garden hose booster system.
Abstract:
An assembly for controlling water turbulence through a high pressure cleaning machine includes a nozzle body, which has an inlet, an outlet, and a flow path. The nozzle body has a fastening end that is designed to couple the nozzle body to a pressure washer, at an end of a spray gun shaft, for example. The nozzle body also includes a plurality of conduits (e.g., an array of tubules) arranged in parallel with each other along the flow path and located between the inlet and the outlet. Additionally the nozzle body may include a screen or screens positioned along the flow path. The plurality of conduits and the screens are designed to reduce a turbulence of a water flowing through the assembly.
Abstract:
A method and system for remotely monitoring the status of a standby generator. The system includes a PLC transmitter in communication with the control unit for the generator. The PLC transmitter receives error codes from the control unit of the generator and transmits encoded error codes over the power distribution network in a home using a PLC frequency. A remote status display device can be connected to the power distribution network in the home at any convenient location. The remote status display device includes a PLC receiver that decodes the error codes. The decoded error codes are displayed on a display of the remote status display device for viewing by the home occupant at a location remote from the standby generator.
