Bistable valve powered by an electric motor

摘要

The electrically-actuated bistable valve (1) has a bistable switching function with two switching states having the valve units (4,24). The valve units are cooperative with the valve seat (2,36). An electrical actuator has an electro motor (8) with a rotor and a stator. The rotor drives a rotary element of a gear (10) for converting the rotational movement of the rotor into a linear movement of a linear element of the gear. An independent claim is also included for an electrically-actuated parking brake device with a driving position.
