Abstract: An internal combustion engine may include a first piston reciprocatingly disposed in a first cylinder, and a second piston reciprocatingly disposed in a second cylinder. A crankshaft may be coupled with the first piston and the second piston for rotational motion associated with reciprocating movement of at least one of the first piston and the second piston. A combustion chamber may be fluidly coupled with the first cylinder and the second cylinder. An ignition source may be at least partially disposed within the combustion chamber. An intake valve may provide selective fluid communication between an intake system and the combustion chamber, and an exhaust valve may provide selective fluid communication between an exhaust system and the combustion chamber.

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 electric starting system is provided for an engine. The electric starting system may include a self-contained housing configured to be mounted between an engine and a tool driven by the engine. The electric starting system may also include an electric motor mounted to the housing, the electric motor configured rotationally engage an output shaft of the engine to effectuate starting of the engine.

Abstract: Systems and methods are provided for transferring fluid between a container and a reservoir. In an embodiment, a system may include a container having an interior volume configured to hold a volume of fluid. An adapter may be associated with the container for providing fluid communication with the volume of fluid. A receiver may be configured to be fluidly coupled with a reservoir. The receiver may be configured to releasably engage the adapter, and may include a valve configured to be opened when the adapter is engaged with the receiver to allow fluid transfer between the container and the reservoir.

Abstract: A fluid sensing safety may include a pump, and a prime mover configured to drive the pump. A fluid vessel may be associated with the pump. A sensing system may be configured to determine the presence of fluid within the fluid vessel.

Abstract: A valve arrangement including a release valve. The valve arrangement controls a cylinder assembly including a first port and a second port, and a cylinder slideably housing a piston for movement between an extended position and a retracted position. The valve arrangement includes a valve assembly in fluid communication with the source of fluid pressure and with the first port and the second port to control fluid flow between the source and the first port and second port, and a release valve fluidly connected to the first port and to the second port, the release valve being operable to control flow of fluid from the first port and from the second port. The release valve is movable between a closed position and an open position. Fluid flows from both the first port and the second port simultaneously when the release valve member is in the open position.

Abstract: A clamp for clampingly engaging a portion of a workpiece and for lifting the workpiece from a work surface.

Abstract: An improved high-voltage discharge electrode assembly for an electrostatic precipitator is disclosed. The discharge electrode assembly comprises, in combination, an elongated discharge electrode, an anchoring element, one end of the elongated discharge electrode being secured at the anchoring element, and a flexible shroud closely surrounding the elongated discharge electrode adjacent the anchoring element whereby the life of the electrode in the electrostatic precipitator is extended. In a preferred form, the flexible shroud is a closely coiled, cylindrical helical spring.
