摘要： A pressure regulator is associated with a solenoid-operated valve that is operated by a pulse waveform at a fundamental frequency substantially greater than the frequency response of the valve mechanism. This substantially attenuates solenoid pulsations and applies a predetermined pressure differential across the valve mechanism to accomplish improved flow control accuracy. The invention is especially advantageous for purging fuel vapor to an intake manifold of an internal combustion engine of an automotive vehicle.

摘要： An emission control valve assembly has an internal main flow passage through a valve body between a first port and a second port, an electric actuator, and a valve operated by an armature of the actuator to selectively open and close the passage. A force-balancing mechanism applies to the valve a force that opposes force created by pressure differential between the first and second ports. An annular filter cartridge is disposed within the valve body to trap particulate material in flow entering through the first port so that the trapped material does not reach the valve and its seat.

摘要： A rotary proportioning valve has a valve body with two inlet ports and an outlet port spaced apart about an axis. The valve body has a circular side wall and a first circular end wall closing one axial end of the side wall. Each of the ports intercepts at least the first end wall to communicate with interior space of the valve body. A shutter disposed within the interior space is supported for rotary positioning about the axis, and is operated by a shaft that extends through a second end wall that closes the opposite end of the body side wall. The shutter has a circular wall that confronts at least the first end wall. Plural fenestrations in the circular shutter wall are positioned relative to respective body ports in accordance with positioning of the shutter for proportioning flows into the inlet ports into a proportioned flow from the outlet port. A spring-loaded mechanism within the interior space of the valve body bears against the second end wall to maintain the circular shutter wall confronting the first end wall. In one embodiment, the shutter has an axial wall on the perimeter of the circular wall, the fenestrations extend into that axial wall, and the ports also extend into the side wall of the body.

摘要： An evaporative emission control system for a fuel system of an internal combustion engine of an automotive vehicle has a purge flow path through which an evaporative emission containment space of the fuel system for containing volatile fuel vapors is purged to an intake system of the engine. A purge valve controls purge flow through the purge flow path. When the intensity of intake system vacuum falls below a threshold, an electric-motor-driven blower operates to creates a pressure rise in the purge flow path upstream of the purge valve and downstream of the containment space. A differential pressure sensor senses pressure differential across the purge valve, and the purge valve includes an integral valve position sensor, both sensors providing feedback signals to a controller than controls operation of both the purge valve and the blower.

摘要： A valve assembly (14) has an internal main flow passage through a valve body (24) between a first port (25) and a second port (26), an electric actuator (30), and a valve (86) operated by an armature (58) of the actuator to selectively open and close the passage. A force-balancing mechanism (92) applies to the valve (86) a force that opposes force created by pressure differential between the first and second ports. This mechanism includes an internal chamber (126) bounded in part by a fluid-impermeable movable wall (94) that extends between and is sealed to both the body (24) and the valve (86), and a communication passage (110, 112) that communicates one of the ports (26) to the chamber space when the valve is closing the passage. The valve (86) has a head part (88) and a seal part (90) joined together. The seal part seals the head part to the valve seat (29) when the valve is closing the passage. A retainer part (116) holds the inner margin of the movable wall sealed on the head part. The communication passage extends through the valve to communicate with the chamber space at a region of the valve disposed within the chamber space. The valve also has cushion media (76, 80, 142) that cushions impact of lateral displacements of the armature, an overmold (32) that encloses internal parts, and sonic nozzle structure (28).

摘要： An on-board diagnostic system for an evaporative emission control system of an internal combustion engine powered vehicle employs a positive displacement reciprocating pump to create in evaporative emission space a pressure that differs significantly from ambient atmospheric pressure. The pump is powered by using engine intake manifold vacuum to force an intake stroke during which both an internal spring is increasingly compressed and a charge of ambient atmospheric air is created in an air pumping chamber space. Vacuum is then removed, and the spring relaxes to force a compression stroke wherein a portion of the air charge is forced into the evaporative emission space. The rate at which the pump reciprocates to alternately execute intake and compression strokes indicates the pressure and flow through a leak in the evaporative emission space. Detection of this rate serves as a measurement of leakage for the purpose of distinguishing integrity of the evaporative emission space from non-integrity. The disclosed pump has a novel arrangement of its internal valving that reduces the number of parts required in comparison to a previous pump.
