Abstract
A reversible d.c. motor adjusts the position to which a carburetor throttle valve closes. The throttle valve is mounted on a throttle shaft to one end of which is attached a throttle lever. The motor has an extendable and retractable member one end of which contacts the throttle lever, a rotatable shaft which rotates in one direction or the other when the motor is energized and a gear arrangement for translating rotary movement of the shaft into linear movement of the member. An improvement comprises a switch for de-energizing the motor as the member approaches either extreme of its extending or retracting movement. Deenergization of the motor stops movement of the member before the respective extreme is exceeded thereby to prevent damage to the motor.
