Abstract

A direct drive valve includes a rotary motor transmitting a linear movement to a hydraulic valve through an arm linked to the engine and acting on a clevis integral with the valve. A spring acting on one end of the valve provides clearance adjustment of the connection between the engine and the valve and enables the return of the latter into a predetermined safety position in the event of breakdown of the system. The valve is for use in motor vehicle applications.
