Abstract: A high-pressure water pump for a pressure washer system includes an elliptical cam, a piston, and an unloader. The elliptical cam is designed to be powered by a prime mover, and is rotatable between a first orientation and a second orientation. The piston is designed to be driven within a chamber by the elliptical cam. During operation of the water pump, a flow of water enters the chamber through an inlet when the elliptical cam rotates to the first orientation. The flow of water exits the chamber at an increased pressure through an outlet when the elliptical cam rotates to the second orientation. The flow of water then exits the water pump through the unloader, which is designed to control pressure fluctuations in the flow of water, and is attached to the outlet of the chamber.

Abstract: A pressure washer includes a frame and an engine coupled to the frame. The engine has a throttle configured to control the speed of the engine. The pressure washer also includes a pump attached to the frame. The pump includes a housing with an inlet and an outlet formed in the housing. A flow path extends between the inlet and the outlet. The pump has a through mode, permitting water to flow through the flow path. And, the pump has a bypass mode establishing a recirculation circuit. The pressure washer also includes a pressure-sensitive member positioned along the flow path and attached directly to the recirculation circuit when the pump is in the bypass mode. The pressure-sensitive member has a first response to a water pressure occurring during the bypass mode and a second response to a water pressure occurring during the through mode. The pressure washer further includes a line of communication between the pressure-sensitive member and the throttle. When the pressure-sensitive member has the first response, the throttle sets a first engine speed, and when the pressure-sensitive member has the second response, the throttle sets a second engine speed.

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: An idle down controller for pressure washers is responsive to the drop in pressure at the pump outlet. The controller includes a sensor disposed in the pump outlet manifold. When the fluid is being bypassed, the manifold pressure drop is communicated to an actuator. The actuator overrides the engine governor and forces the engine throttle to the idle speed. When an operator is discharging a pressurized fluid, the actuator allows the governor to operate the engine at its normal speed.
