摘要： A fuel vapor management valve or VMV having an electrically operated vent valve for controlling atmospheric bleed flow to a vacuum signal pressure chamber. The pressure in the signal pressure chamber controls the differential pressure acting on opposite sides of a diaphragm which moves a valve member for regulating fuel vapor purge flow from a canister to the engine intake manifold. Vacuum is applied to the signal pressure chamber through restrictive passages in a connector which prevent sonic flow choking. In one embodiment two orifices are spaced fluidically in series. In another embodiment fluidically parallel laminar flow passages are provided in an element comprising a porous filter preferably formed of fibrous material or sintered metal. In another embodiment, the laminar flow element is disposed fluidically in series with a flow restricting orifice.

摘要： An electrically controlled vacuum operated valve controls flow of fuel vapors from a collector canister to the engine intake manifold. A pressure regulator controls fuel vapor flow from the canister to the inlet of the electric valve and is normally closed. During engine operation, if the control valve maintains a threshold level of vacuum at the regulator outlet, the regulator will permit fuel vapor flow from the canister to the control valve, otherwise the regulator is closed.

摘要： A remotely actuated solenoid latch apparatus adapted for use in motor vehicle applications is disclosed. The solenoid latch apparatus includes a solenoid having an armature movable between a first position displaced from a pole piece to define a working air gap therebetween to a second position attracted toward the pole piece. A solenoid winding encircles the pole piece and the armature for attracting the armature toward the pole piece upon energization thereof. A latch member is associated with the movable armature for lockingly engaging a striker bar when the armature is in one position and releasably disengaging the striker bar when the armature is in the other position. The present invention is self-compensating to align the latch member relative to the striker bar, prior to engagement therewith, to compensate for alignment variation between the latch member and the striker bar. The pole piece is movable to provide a relatively constant air gap upon alignment of the latch member relative to the striker bar when the armature is displaced from the pole piece.

摘要： A transmission shift interlock device which prevents a motor vehicle operator from shifting the automatic transmission shift lever out of the park or neutral position unless some action such as the brake pedal being depressed is taken. The device provides interlock capability by locking the transmission shift cable. An in-line solenoid is provided within the shifter cable having a movable armature which, when energized, forces locking balls or other engagement features into interlocking engagement with the cable core or rod member attached thereto. An alternate embodiment provides an adjustment link for accommodating vehicle tolerance variations and further provides means for having interlock capabilities at more than one shifter position.

摘要： A throttle positioning device comprising a housing and a diaphragm in the housing dividing the housing into first and second chambers. The housing has an opening extending to the first chamber for connection to vacuum. A solenoid is associated with the housing and has a plunger acted upon by energization of the solenoid. The plunger is yieldingly urged by a light spring against a solenoid stop connected to the diaphragm such that the stop is movable with the diaphragm. A stem is adapted to be moved by the plunger and extends through the movable stop to the exterior of said housing to define a movable throttle stop. The throttle lever, attached to the throttle shaft of the carburetor yieldingly urges the throttle stop to a retracted position against the lighter spring force of the solenoid plunger. The diaphragm is yieldingly urged to move the movable solenoid stop toward the solenoid. When the solenoid is energized and vacuum is not being supplied to the first chamber, the stem is in a first position, and when said solenoid is energized and vacuum is supplied to the first chamber, the stem is in a second position. When the engine is stopped and the solenoid de-energized, the throttle element urges the stop to a third position against the action of the lighter spring to provide an anti-dieseling function. In another form, the throttle positioning device includes a wall in the housing cooperating with the first diaphragm to form a second chamber, and a second diaphragm cooperates with the wall to define third and fourth chambers. The housing has an opening for connection to vacuum to the third chamber. The first and second diaphragms are movable independently of one another, such that when the solenoid is energized and vacuum is applied to the second opening, the second diaphragm moves the first diaphragm to move the magnetic stop permitting the stem to be moved by the solenoid plunger to a fourth position.
