A switching control valve for use in controlling the motion of a hydraulic component is provided. The valve includes a housing that defines a feed port, an outlet port, a drain port, and a longitudinal opening through the housing. The valve also includes an inlet valve moveably positionable in the longitudinal opening for selectively fluidly connecting the feed port to the outlet port, as well as a drain valve moveably positionable in the longitudinal opening for selectively fluidly connecting the outlet port to the drain port. The valve further includes a valve shaft that is moveably positionable in the longitudinal opening, such as by a solenoid or similar control device, and is operably connected to the inlet valve and the drain valve. The housing, the inlet valve and/or the drain valve are configured to provide permanent fluid communication between the outlet port and the drain port.

A pressure balanced three-way solenoid valve including a valve housing having a valve chamber and a high pressure fluid supply passage, high pressure fluid outlet passage and drain passage communicating with the valve chamber is disclosed. A movable valve member is reciprocally received in the valve chamber so as to be reciprocated between first and second positions for selectively fluidically communicating the outlet passage with either the supply passage or drain passage. A first valve seat is formed in the valve housing and concentrically disposed in the valve chamber for fluidic communication between the outlet passage and drain passage and a second valve seat is concentrically disposed in a cavity formed in the movable valve member for sealing communication between the supply passage and outlet passages. A floating pin is received in the movable valve member cavity and communicates with the second valve seat for selectively fluidic communication between the supply passage and outlet passage with the floating pin including an impact absorbing element for absorbing the impact of the movable valve member when the movable valve member contacts the floating pin during de-energization of the solenoid. Transitional losses are readily controlled and a high initial closing velocity may be achieved while preventing closing bounce and thus the formation of any leakage path between the floating pin and movable valve member upon de-energization of the solenoid.

A three-way valve including a valve housing having a valve chamber and a high pressure fluid supply inlet, high pressure fluid outlet and drain communicating with the valve chamber is disclosed. A movable member is reciprocally received in the valve chamber so as to be reciprocated between first and second positions for selectively fluidically communicating the outlet with either the inlet or drain. A first valve seat is formed in the valve housing and concentrically disposed in the valve chamber for sealing communication between the outlet and drain and a second valve seat is concentrically disposed in a cavity formed in the movable member for sealing communication between the inlet and outlet. A floating pin is received in the movable valve member cavity at a one end of the movable valve member and cooperates with the second valve seat for selectively sealing fluidic communication between the inlet and the outlet. An actuating device is mounted on the valve housing adjacent an end of the movable valve member opposite the floating pin for advancing the movable valve member toward the first position when energized and for allowing the movable valve member to retract to the second position when de-energized.

A unitized fuel supply assembly is disclosed including an in-line reciprocating cam driven pump (14) for supplying fuel to an accumulator (12) from which fuel is directed to a plurality of engine cylinders by means of a distributor (16) mounted on the unitized assembly. Dual pump control valves (20) provide fail safe electronic control over the effective pump displacement. One or more injection control valves mounted on the distributor are provided to control injection timing and quantity. The accumulator (12) contains a labyrinth of interconnected chambers (36) which are shaped and positioned to produce a minimum overall package size while providing for easy manufacture.

A fuel injector assembly is provided which operates to effectively creating a low injection flow rate followed by a high injection flow rate during all engine operating conditions, including idle and low engine speed conditions, to produce a high quality fuel spray with proper atomization and thus improved fuel air mixing resulting in improved emissions abatement and fuel economy. The assembly includes two biased valve elements designed to sequentially open and close to initially open a limited number of orifices followed by the opening of a remainder of the orifices thereby effectively varying the available cross sectional flow area from the nozzle cavity into the combustion chamber of the engine during the injection event. The nozzle valve elements may be spring biased or fluid pressure biased and include biasing surfaces sized to cause the sequential opening and closing of the elements.

An open nozzle unit fuel injector having an injector body for receiving a plunger assembly therein is disclosed including a fuel supply source for providing a metered quantity of fuel to a metering chamber formed in a central bore of the injector body to be injected into the cylinder of the internal combustion engine and a trapped volume spill port for a volume of fuel trapped in the metering chamber when the plunger has moved from its fully retracted position to its fully advanced position and injection has terminated. In accordance with the present invention, an open nozzle unit fuel injector is achieved which exhibits a sharp ending of injection, which prevents secondary injection and which significantly reduces the unburned hydrocarbon emissions of the engine incorporating such open nozzle unit fuel injectors including a trapped volume spill port.

A three-way fuel injection control valve assembly is provided which includes a pilot valve for controlling the movement of a drain valve member and a separate supply valve member to minimize valve response time and transition flow losses. The solenoid operated two-way pilot valve controls the flow of fuel from a control volume formed adjacent the ends of the drain valve member and the supply valve member to begin and end an injection event. A transition flow loss limiting feature is provided which causes the drain valve member to close prior to the opening of the supply valve member and subsequently causes the supply valve member to close prior to the opening of the drain valve member during a given injection event thereby minimizing transition flow losses. The transition flow loss limiting feature includes sizing the cross sectional areas of the supply valve member and the drain valve member, sizing a bias plunger for biasing the drain valve member and sizing one or more bias springs so that no opening overlap occurs between the supply valve member and the drain valve member.
