Abstract: 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.

Abstract: 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.

Abstract: An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated axially movable armature which is directly coupled to a rotatable lever. The lever is normally biased to a latched position. The lever is lockingly engageable with a rotatable pawl which is normally biased to a latched position. The pawl engages a pair of rotatable, asymmetrically oriented striker cams which are normally biased to an unlatched position. The striker cams define a cavity for engaging a striker. Upon energization of the solenoid, the armature is attracted to the solenoid causing it to rotate the lever so as to disengage the pawl. The normal biasing of the striker cams overcome the biasing of the pawl to rotate the striker cams to the unlatched position thereby opening the deck lid. When the deck lid is closed, contact with the striker over-rotates the striker cams permitting the pawl to rotate to a latched position thereby lockingly engaging the lever.

Abstract: An electrically controlled transmission shift interlock device. The device provides interlock capability by locking the pivotable shift actuating lever which is operatively associated with the transmission. A transmission mounted solenoid is provided having a moving armature coupled to a locking member which, when energized, positions the locking member into interlocking engagement within an engaging notch provided in the shift actuating lever. The device includes means for proper alignment of the interlocking components during installation of the interlock device onto the transmission. One alternate embodiment further provides means for having interlocking capabilities at more than one gear shift lever position. Another embodiment causes the transmission actuating lever to lock when the solenoid is de-energized and is movable upon energization.

Abstract: For use in applying a vacuum to a choke pull-off assembly, a temperature compensating vacuum delay valve comprising a housing a first opening adapted to be connected to manifold vacuum and a second opening adapted to be connected to a choke pull-off assembly which functions to partially open the choke when a vacuum is applied. The housing includes a valve disc, yieldingly urged against the seat. A restrictor permits restricted flow between the one side of the valve disc and the other side of the valve disc when the valve disc is in sealing and a bi-metallic disc is positioned in the housing between the first opening and the valve disc and is operable upon predetermined change of temperature to move the valve disc away from a seat and thereby permit unrestricted flow between the first opening and the second opening. The valve disc is spring loaded against the seat such that it will open and allow unrestricted flow in the reverse direction.

Abstract: For use in a turbocharger system wherein exhaust flow from the engine is caused to rotate an impeller and charge the intake of the engine with compressed air, a water injection system comprising a water reservoir, a first line connecting the reservoir to the intake from a point above the liquid in the reservoir, a second line extending from below the level of liquid in the reservoir to the intake of the impeller and a check valve in the second line. The check valve includes a valve body having an inlet and an outlet, a seat separating the inlet and the outlet, a valve member, and a spring external of the valve member and of the flow of water through the inlet, outlet and seat yielding urging the valve member into engagement with the seat. The check valve may also be utilized in a fuel system wherein a fuel pump directs fuel to electronically controlled fuel nozzles. The check valve is placed in the line between the fuel pump and the fuel nozzle.

Abstract: A positioning device comprising a solenoid, said solenoid having a plunger slidable upon energization of the solenoid, a solenoid stop associated with said solenoid, a stem operatively connected to said plunger and extending through the movable stop to the exterior, an actuator connected to said solenoid stop and operable to move said stop to selected positions, such that when the solenoid is energized, the plunger is moved to engage the stop and move the stem to a predetermined position, the extent of movement being determined by actuation of the actuator to move the stop in predetermined positions.

Abstract: 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.

Abstract: An automatic choke control which includes a housing, a bimetallic coil in the housing having an output shaft for connection to a choke to move the choke toward a closed position when the temperature of the engine is low and to move the choke toward an open position when the temperature of the engine rises, and a body of porous material impregnated with a material such as paraffin that is normally solid and becomes liquid at an elevated temperature. The body of impregnated material is mounted on the exterior of the choke control housing so that it functions as a heat sink to store thermal energy in the solid material converting the material to a liquid.
