Abstract:
A vehicle gear box shift actuator and apparatus including the same. The actuator includes a lead screw; a drive nut threaded on the lead screw; a plunger; a first spring disposed between the drive nut and a first end of the plunger; a second spring disposed between the drive nut and a second end of the plunger opposite from the first end. Non-contact position sensing of the actuator output is also provided.
Abstract:
An electromechanical actuator including an output shaft structure coupled to an output gear to allow relative motion therebetween upon application of a predetermined level of force to the output shaft structure. The relative motion opens a normally closed conductive path between a motor for driving the output gear and a power supply input terminal. Integrated position control is provided whereby the conductive path is opened at limits to the range of motion for the output shaft established by location of the ends of stationary contacts. A fuel filler valve system and a method of providing pinch protection are also provided.

A vehicle gear box shift actuator and apparatus including the same. The actuator includes a lead screw; a drive nut threaded on the lead screw; a plunger; a first spring disposed between the drive nut and a first end of the plunger: a second spring disposed between the drive nut and a second end of the plunger opposite from the first end. Non-contact position sensing of the actuator output is also provided.
Abstract:
A fuel filler door actuator including a motor, a gear train coupled to the motor and to a latch arm, and a locking cam coupled to the gear train. The locking cam resists movement of the latch arm from an unlocked condition to a locked condition. A manual override cable is disclosed for manually moving the latch arm from the locked condition to an unlocked condition. A push-push mechanism is disclosed for allowing facile opening of a fuel filler door, and a quick connect/disconnect feature is disclosed for allowing facile assembly of the actuator to a fuel filler door housing.

Abstract:
A thermostat actuator is provided for controlling a flow rate of coolant through a cooling system. The actuator includes a motor and a drive train including an anti-back-drive mechanism. The actuator further includes an integral position feedback system that for indicating a position of an element of the actuator to ensure that the actuator has moved to a commanded position. The actuator is configured to be readily adaptable to different position feedback systems providing varying degrees of position feedback resolution.
Abstract:
An actuator and door latch system incorporating the same. The actuator moves a door latch between locked and unlocked positions with rapidity using a gear train directly coupled to an actuator motor or energy stored in an energy storage element such as a spring.
