Abstract: A pump includes a cam plate, and an input shaft for rotationally driving the cam plate. A pump housing at least partially surrounds the cam plate and defines a cam plate oil reservoir around at least a portion of the cam plate. A bearing support is at least partially disposed within the cam plate oil reservoir. The bearing support defines a bearing oil reservoir at least partially surrounding a portion of the input shaft. At least one passage extends between the bearing oil reservoir and the cam plate oil reservoir. Dynamic motion imparted on oil within the cam plate oil reservoir facilitates migration of oil from the cam plate oil reservoir through a bearing at least partially supported by the bearing support into the bearing oil reservoir and through the at least one passage into the cam plate oil reservoir.

Abstract: A pump includes a pump body. The pump may also include a pump mounting flange configured to mount the pump to an engine flange including four clocked mounting holes. The pump mounting flange may include a first set of four mounting holes corresponding to the four clocked mounting holes in a first orientation. The pump mounting flange may include a second set of four mounting holes corresponding to the four clocked mounting holes in a second orientation.

Abstract: A pressure washer system includes a fluid pump having a fluid inlet and a fluid outlet. A flow sensor is in fluid communication with one of the fluid inlet and the fluid outlet. An internal combustion engine is in driving communication with the fluid pump. A control module is mounted to the fluid pump. The control module is configured to receive an indication of flow through the fluid pump and to control a starting operation of the internal combustion engine to start the internal combustion engine in response to receiving the indication of flow through the fluid pump when the internal combustion engine is not running.

Abstract: An aluminum alloy is provided including between about 7.5-9.5 wt. % silicon, between about 3.0-4.0 wt. % copper, and between about 0.01-5.0 wt. % titanium. The aluminum alloy may include up to about 1.3 wt. % iron, up to about 0.5 wt. % manganese, up to about 0.1 wt. % magnesium, up to about 3.0 wt. % zinc, and up to about 0.35 wt. % tin. The balance of the aluminum alloy may include aluminum.

Abstract: In an embodiment, a variable flow pump may include a swashplate rotatably driven by a driveshaft. The swashplate may be movable between a first and second tilt angle relative to the driveshaft. A piston pump may be reciprocatingly driven by the swashplate based upon, at least in part, the tilt angle of the swashplate. An actuator piston may be moveable between a first and second position based upon, at least in part, a downstream backpressure of a fluid pumped by the piston pump. An actuator assembly may be moveable between a first and second position based upon, at least in part, the position of the actuator piston. The actuator assembly may include a swashplate driver configured urge the swashplate between the first and second tilt angles, and a biasing driver configured to apply a force urging the swashplate into contact with the swashplate driver.
