A throttle cable intervention servoactuator having a connector link with a lefthand thread on one end and a righthand thread on the opposite end with correspondingly threaded connecting members engage the threaded ends of the link and the members each guided in a slot in a housing for non-rotating sliding movement with the connector link. A driven gear is journaled for rotation on the housing with the connector link extending centrally through the driven gear in free sliding engagement and engaged for rotation by the gear. The driven gear is rotated by a motor in response to a signal to change the effective length between the connector members when each are connected to one end of a throttle tension cable.

A quick vent response valve (12) is fluidically series connected between a vacuum regulator valve (14) and an exhaust gas recirculation valve (16) which comprises a fluid pressure control system (10). The quick response valve operates to vent the system more quickly than if the system were vented through the vacuum regulator valve itself by employing the modulated control signal from the vacuum regulator valve as a pilot signal. The quick response valve improves response time of the vacuum system when venting from a high to a low vacuum level by momentarily displacing a valve element (56) disposed within a housing (18) to establish a nonrestricting flow path to atmosphere.

An electro-vacuum relay 10 is disclosed comprising a thermally responsive actuator 18 mounted on the lower end of a housing 14, 16 which defines a vent chamber 66. Upper and lower fluid ports 38, 40 are integrally molded into the housing and communicate with vent chamber 66. A pair of electrical terminals 22 and 24 include tab portions 30, 32 which extend through housing cover 16 and into the vent chamber. A carrier member 68 is movable in the vent chamber and has reacting against its upper end a compression biasing spring 88 and against its lower end an output member 64 of thermal actuator 18. A rectangularly shaped elastomeric valve member 72 is mounted in an opening 74 in the carrier and has an upwardly extending double beaded sealing surface 76 around its periphery that engages with a valve surface formed by an inner wall portion 42 of main housing 14. An electrical contact member 80 is received in another opening formed in carrier 68 and is spring biased outwardly toward tab portions 30, 32 by a spring 82 which also functions to seat the valve member against inner wall portion 42.

Disclosed is a system for controlling both cruising speed and engine idling speed of a vehicle. The system includes an electronic control module that controls an actuator (100) having a moveable member preferably in the form of a gear rack (6) that is pivotably mounted to an intermediate member (8) that is operably connected to the engine throttle and adapted to move in opposite directions along a frame (2) of the actuator. The actuator is provided with means, preferably in the form of an idle speed control switch (34), for sensing when the throttle is being controlled by the operator and causing the control module to switch its output from a second control signal to a first control signal and feedback means, preferably in the form of a differentiating switch (47), for determining an idle speed pick-up position for the moveable member that is more than the desired regulated engine idle speed position but not more than the operator selected cruising speed position.

A temperature control system for a passenger van having individual temperature selection controls for passengers in the forward and rear sections of the passenger compartment. Separate exothermic heat exchangers for circulation of engine coolant therethrough are provided for the forward and rear passengers. Each heat exchanger is supplied by a coolant control valve and individual blowers provide a stream of forced air over the heat exchangers. A thermistor senses the temperature of the air discharge over each heat exchanger and a controller sums the sensed temperature signal with a user selected relative temperature reference signal provided independently by the forward and/or rear passenger selector inputs and a valve position signal; and, the controller generates a control signal proportional to the summation. An electrical actuator for each valve moves the valve until the sum is a null for controlling coolant flow to each heat exchanger to thereby regulate the discharge air temperature about the individually selected relative levels for the front and rear independently of the selected blower speed. Air conditioning evaporators may be disposed upstream of each of the heat exchangers; and, the thermistors sense the combined effect of heating and cooling and the system continues to modulate coolant flow to the heat exchangers for temperature regulation.

A dual vacuum control signal generator (10) is supplied by separate vacuum sources (34, 85) and employes a solenoid coil operative upon receipt of modulated pulses (148) for switching a valve member (192) between opposing vent seats (142, 196) for controlling venting to create plural vacuum output control signals supplied to connectors (16, 14) for connection through conduits (68, 78) to separate vacuum actuators (60, 70) for individually controlling the position of engine carburetor fuel metering rod (49) and idle mode throttle position cam (88).

A low voltage direct current motorized servoactuator having an output gear position feedback potentiometer with a ring gear received initially loosely on the potentiometer shaft and in engagement with the output gear. A collar keyed hinged to the potentiometer shaft, but axially movable thereon, permits the output gear to be positioned independently of the potentiometer for calibration without disengaging the ring gear. With the output gear in the desired position, the potentiometer shaft is rotated until the potentiometer reads the desired percentage of its full scale resistance or voltage output; and, the collar is then moved axially to a press fit with the ring gear to lock the calibration and thereafter to rotate the potentiometer shaft with rotation of the ring gear. The motor drive pinion is a worm formed of material having a minor fraction (18%) of chloro-fluorinated polymer and a lesser fraction (2%) of lubricant, balance polyimide plastic material. The driven gears are formed of material having a minor fraction (18%) of chloro-fluorinated polymer and a lesser fraction (2%) of lubricant, balance acetal plastic material.

A servoactuator for a vehicle throttle having a direct current motor driving a speed reducer with the output thereof connected to slidably move a fulcrum member having a lever arm pivoted thereon. The lever arm has a cable to the engine throttle connected to one end and a cable to the vehicle accelerator pedal connected to the other end on the opposite side of the pivot. In one embodiment the speed reducer drives an axial lead screw threaded in the fulcrum member. In a second embodiment the speed reducer output is a slotted crank arm having a pin on the fulcrum member slidably received therein. In a third embodiment the speed reducer output is connected by a two-bar linkage to the fulcrum member. A potentiometer is disposed to have the movable element thereof moved by one end of the lever to provide a throttle position feedback signal for use by an external motor control signal generator. The servoactuator is intended for use with a vehicle traction control system.
