Abstract: An all-electric pressure washer heater module having a heating coil and a heating element is disclosed. A system for all-electric pressure washing is further disclosure. In particular, the all-electric pressure washer heater module contains the heating element from exposure to corrosion and fouling.

Abstract: A light weight portable pressure washer with improved vibration damping includes a plate member disposed between the engine and the supporting frame of the pressure washer. The plate member is mounted to the base of the engine and extends laterally beyond the base of the engine and is supported on the frame of the pressure washer by multiple elastomeric vibration isolators. The plate member and the frame may be constructed of stainless steel or of aluminum, and the frame components may be joined without welding.

Abstract: The blower/ignition/electrical system supplies the air, spark, and electrical power to facilitate and control the fuel combustion in a heat exchanger for devices which output a fluid, such as a pressure washer. The system is belt driven as an intricate part of the mechanical power system used for the fluid pressure pump. The flange/magnet hub spins past the ignition coil which in turn produces a high voltage electrical source. This potential is applied across the electrode gap to ignite a fuel. The flange magnet hub also spins past a stator coil assembly which in turn produces an alternating current. This current can be rectified or left unrectified, and is wired to a switch. When the switch is activated, the current path is through the safety control devices (such as temperature control, pressure switch or flow switch) and the fuel solenoid valve which controls the fuel flow into the combustion chamber.

Abstract: An apparatus for coupling a vertically oriented internal combustion engine to an axial piston pump for use with pressure washers. Attached to the lower surface of the engine is a circular flange with inwardly extending ribs which supports a pump attachment unit. The pump attachment unit is comprised of a series of concentric annular rings for an oil seal and thrust bearing and for pump attachment. The pump drive shaft slides over and is keyed to the engine drive shaft and has an annular lip for mating with the thrust bearing. The pump wobble plate is bolted to the lower end of the pump drive shaft.
