Abstract:
A water pump includes a base, a cam, a joint, and a piston. The base includes a PTO-attachment portion, a cam-attachment portion, a first contact surface, and a second contact surface. The cam includes a central opening, a first cam contact surface, and a second cam contact surface, wherein the cam-attachment portion of the base extends into the central opening. The joint pivotally couples the cam to the cam-attachment portion of the base. In a first operating position of the cam, the first contact surface engages the first cam contact surface so that the cam is positioned at a first angle relative to the axis of PTO rotation. In a second operating position of the cam, the second contact surface engages the second cam contact surface so that the cam is positioned at a second angle, greater than the first angle, relative to the axis of PTO rotation.
Abstract:
A pressure washer includes an engine having a vertical shaft and a pump designed to be powered by the engine. Additionally, the pressure washer includes a base plate, where the engine is coupled to the base plate with a first set of fasteners and the pump is independently coupled to the base plate with a second set of fasteners. The base plate is designed to allow the engine to be unfastened and removed from the base plate without also unfastening the pump.
Abstract:
A window power distribution device includes a housing with an extension attached to the housing. Together, the housing and extension are designed to form a seal in a window opening. The window power distribution device also includes an electrical input attached to the housing, a display, and a socket, where the socket is wired to the input. The display is designed to provide information relating to the power distribution device.
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:
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 wand is connectable to a source of fluid. The pressure washer wand 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 between a locked position in which the lock assembly inhibits movement of the user interface, and an unlocked position.
Abstract:
A water spraying system is configured for a variety of outdoor cleaning applications. In one embodiment, the water spraying system includes a water pump assembly having a water pump, a receiver configured to receive wireless communications, and an actuator coupled to the receiver and configured to change at least one of water pressure and flow rate provided by the water pump. A spray gun is configured to spray water provided by the water pump and includes an electronic display, circuitry configured to provide a graphical user interface via the electronic display, and a transmitter configured to wirelessly provide instructions to the actuator by way of the receiver based on input provided by the operator such that the operator may change at least one of the water pressure and the flow rate provided by the water pump via the graphical user interface of the spray gun.
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.
