A solenoid valve system, wherein the valve member is provided with a seal member disposed thereabout. The solenoid valve is especially suitable for use with exhaust gas recirculation systems. The seal member is operable to slide axially relative to the valve member, including the stem portion thereof. An optional lubricant is provided between the valve member and the seal member so as to provide a relatively low friction environment therebetween when the valve member is in motion. An optional biasable member, in operable association with the seal member, is provided so as to maintain proper positioning of the seal member, e.g., during operation of the solenoid valve system.

Low friction sliding valve seal

A lead frame disposed within the confines of an engine cover, having an insulating portion and an electrically conducting portion. The conducting portion has at least one electrically conducting interconnect. Both the insulating portion and the electrically conducting portion form an integral piece for retaining and accurately positioning devices within an internal combustion engine. The lead frame includes a plurality of retaining elements for retaining or positioning of at least some of the devices; and an electrical connector member extending outside the confines of the internal combustion engine, the electrical connector member having a plurality of electrically conducting terminals in electrical communication with at least some of the devices within the internal combustion engine by means of the at least one electrically conducting interconnect, whereby at least some of the devices are retained and accurately positioned within the internal combustion engine.

VCT sensor and actuator module

A mounting bracket mechanism and system for mounting a solenoid operated valve, such as an EGR valve, to a vehicle. A strap-type mounting bracket is positioned over the valve and secured to the engine or other vehicle component with a plurality of bolts or other fasteners. A curved recess or groove is provided in an engine component or surface, or a spacer member is positioned between the valve and the engine component or surface in order to maximize surface contact and thus heat transfer between the valve and the vehicle. Spring tab members can be positioned on the mounting bracket in order to minimize vibration of the valve in the vehicle and more securely fix it in place. The mounting bracket, spacer member, and valve can be assembled together as a modular preassembly for mounting to the engine.

An exhaust gas recirculation system includes a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member. The system further includes a drive member mounted to the valve body and including a mechanical output which is rotatable in opposed first and second directions. A gear train is operatively disposed between and in engagement with the rotatable mechanical output of the drive member and the valve member. More specifically, the mechanical output rotating in either of the first or second directions imparts linear, reciprocal motion directly to the valve member through the gear train thereby moving the valve member between opened and closed positions to control the flow of exhaust gas from the exhaust port to the intake port. In addition, the exhaust gas recirculation system further includes a sensor integrated into the valve body and operatively connected to the valve member for detecting the linear position of the valve member as it is reciprocated between its open and closed positions.

An exhaust gas recirculation system for an internal combustion engine including a valve body having an exhaust port adapted for fluid communication with a source of exhaust gas, an intake port adapted for fluid communication with the intake manifold of an internal combustion engine, and a valve member movably supported within the body between open and closed positions thereby controlling the flow of exhaust gas from the exhaust port to the intake port. A diaphragm housing is operatively mounted to the valve body and supported thereby. The diaphragm housing defines a vacuum cavity in fluid communication with a source of negative pressure and an atmosphere cavity in fluid communication with a source of second pressure. A diaphragm member is disposed between the vacuum and atmosphere cavities and is operatively connected to the valve member. The diaphragm member is movable in one direction in response to negative pressure induced in the vacuum cavity and in the opposite direction in response to a biasing force to move the valve member between its open and closed position. An integrated vacuum regulator is mounted to the system and supported thereby. The vacuum regulator is operable to control the movement of the valve member between its open and closed positions by controlling the negative pressure induced in the vacuum cavity. The system also includes an integrated pressure sensor which senses the difference between the pressure in the vacuum cavity and the pressure at the intake port.

A closed-loop controlled system solenoid actuated EGR valve includes an engine mount for attachment to a vehicle engine, a valve housing to which the engine mount is attached, a motor housing positioned above the valve housing, and a sensor housing. The valve housing includes a valve inlet adapted to receive engine exhaust gas and a valve outlet which communicates the engine exhaust gas from the valve inlet to an engine intake system. The motor housing has a bobbin, an armature, and a valve stem disposed in a bore formed therein. The valve stem is in communication with a plunger extending from the sensor housing to monitor the position of the valve stem with respect to the valve seat. A guide bearing is positioned in the housing to guide the armature while a valve stem bearing is positioned in the valve housing to contact and position the valve stem with respect to the valve seat while a valve opening is being closed.
