Abstract: A motor to accessory drive system wherein an electric or gasoline motor, having a housing with a drive shaft end protruding from the motor housing, is mounted with respect to the accessory to be driven, such as a pump or a generator, which also has a housing with a drive shaft protruding from the accessory housing, with a mounting plate secured at one end to the motor housing, and secured at another end to the accessory housing whereby the accessory is supported from the motor. The mounting plate is provided with spaced apertures with the drive shaft ends of the motor and accessory respectively protruding through the apertures in parallel alignment. A drive pulley is mounted on each of the protruding drive shaft ends in alignment in a common plane and an endless belt is in driving engagement with the pulleys.

Abstract: A breather assembly for ventilation and pressure control within a crankcase of a positive displacement motor or pump. The breather assembly includes an intake/exhaust port through the crankcase with a valve seat for the port on an exterior surface of the crankcase. A flexible valve membrane is positioned over the port on the valve seat on the exterior of the crankcase for flexing outwardly to exhaust air under positive pressure from the crankcase to atmosphere and to close the port when the crankcase pressure is neutral or negative. An irregular surface is provided on the face of the valve membrane facing to and engaging the valve seat and this surface is provided with a texture which permits air to flow over the valve seat and into the port in a controlled quantity when a negative air pressure condition is attained in the crankcase whereby a predetermined small vacuum level may be maintained in the crankcase.

Abstract: An air compressor unloader assembly for unloading the compression chamber of an air compressor during a compressor unloading cycle. The unloader assembly includes an unloader piston slidable within an unloader cylinder in the head of the compressor for slidably engaging the intake valve of the compressor and to hold the intake valve open for unloading of the compression chamber of the compressor pump. The unloading cylinder is accessible from an exterior surface of the head via a removable threaded plug in a gas tight arrangement. The plug is dimensioned whereby the unloader piston may be readily accessed for lubrication and/or removed for repair or replacement without having to remove the head from the air compressor cylinder.

Abstract: A pressure washer having a frame supporting a heat exchanger for heating liquid passing therethrough under pressure for delivery to a nozzle for pressure cleaning. A burner unit is positioned for applying flame heat to the heat exchanger for heating liquid in the heat exchanger and a blower is provided for delivering combustion air under pressure to the burner unit. A fuel pump is also provided for supplying fuel under pressure to the burner unit. The burner unit is modular and remotely mounted on the frame from the blower and is readily removable and connected to the blower unit remotely through a duct. The burner unit includes a burner gun contained in a removable burner throat housing having a base with an air inlet for registration with the duct and an outer flame port for exposure of the flame from the burner gun to the heat exchanger. The fuel pump for supplying fuel to the burner is driven directly from the blower.
