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： The valve has a solenoid actuator and a position sensor providing an electric signal of the position of the solenoid armature. The solenoid is an electromagnet coil disposed on a plastic bobbin. The magnetic circuit contains a stator member having a flange disposed against a flange of the bobbin, and the position sensor has a plastic housing having a base that captures the stator member flange against the bobbin flange. The stator member flange contains apertures through which non-metallic material that joins with the bobbin flange passes to join with the position sensor housing base, thereby uniting the bobbin and the position sensor housing in assembly capturing the stator member flange. The assembly may be fabricated by an insert molding method or a method in which joining material is melted.

摘要： A method of forming a composite extrusion is disclosed wherein a main body portion (1) of the extrusion is first extruded from a thermosetting material, this body portion then being heated so as at least partly to cure it, the main body portion then being passed at high temperature through a further extruder where a thermoplastics material (8) is extruded onto one or more surfaces of the main body portion (1), the subsequent composite extrusion then being cooled and formed into its final shape. It is important that the combining step be undertaken at a temperature high enough to cause the thermoplastics material to bond to the thermosetting material and while it is simplest for the thermoplastics material to be on an outer surface of the composite extrusion, it is possible for it to be located within the thermosetting material by extruding the thermosetting material in an “opened out” state and then after extruding the thermoplastics and while the extrusion is still hot, folding in edge regions of the main body to overlie the thermoplastics material and bond thereto. The thermoplastics material may be of a special color, may be embossed, and if it is located within the thermosetting material in the end product, may be stiffer than the latter. The invention also extends to the extrusions themselves.

摘要： Apparatus for and method of exhaust gas recirculation in an internal combustion engine that operates with charge air boost. An EGR valve has an inlet port communicated to the engine exhaust system upstream of a throttle valve in the tailpipe and an outlet port communicated to the engine intake system. The throttle valve is controlled to selectively restrict exhaust gas flow through the tailpipe so as to maintain the difference between pressure at the EGR valve inlet and pressure at the EGR valve outlet substantially unaffected by changes in pressure in the intake system and in the exhaust system. The invention is particularly suited for a turbocharged diesel engine.

摘要： A system and method for detecting leakage from a evaporative emission space of an automotive vehicle fuel system. A reciprocating pump is operated in a pressurizing mode to build pressure in the space toward a nominal test pressure. The pressurizing mode involves operating the pump in a repeating cycle wherein the pump operates alternately in an accelerated pumping mode and a natural frequency pumping mode. During the pressurizing mode, a characteristic of successive occurrences of the natural frequency pumping mode indicative of pressure in the space is measured. The number of times the cycle repeats is counted and compared to a predefined reference. When the cycle count exceeds the predefined reference, the test continues at a lower resolution for detecting leakage, and when the cycle count does not exceed the predefined reference and a measurement of the characteristic of successive occurrences of the natural frequency pumping mode indicative of pressure in the space exceeds a predetermined reference pressure, the test continues at a higher resolution for detecting leakage. The invention is useful when overall test time is limited.

摘要： An EEGR valve has a solenoid with an armature supported at each end on circular disks. These disks are fixed to the top and bottom having numerous penetrations (e.g., slots, slits or openings) to permit the disks to be deflected upward or downward. The penetrations are arranged such that when a current is applied to the solenoid coil the armature deflects the disks and permits the armature to move up and down within the coil. The penetrations are arranged as concentric rings of penetrations. The disks are fixed at several locations around their edges to the stator of the solenoid. In this manner, the armature moves back and forth along its axis and not laterally, thus permitting the stator to be located quite close to the armature without wearing against the stator, A spring is provided to preload the armature and deflect the disks in a concave shape different from their unloaded and substantially flat configuration. In this manner, the coil can drive the solenoid.

摘要： A system and a method for recirculating a flow of exhaust gases. The system comprises a passage through which the exhaust gas flow passes, a valve movable in the passage between a generally open configuration and a generally closed configuration, an actuator operatively connected to the valve, and a fail-safe returning the valve to one of the generally open and generally closed configurations if the actuator is disabled. The generally open configuration of the valve substantially permits the exhaust gas flow to pass through the passage, and the generally closed configuration of the valve substantially prevents the exhaust gas flow from passing through the passage. The actuator includes a one-way driver and a release to move the valve between the generally open and generally closed configurations and to vary the exhaust gas flow though the passage. The method comprises energizing the actuator with a power supply, and moving the valve to a fail-safe position if the power supply fails.
