摘要： An actuator device for a control valve is described and comprises a piezoelectric actuating member for bringing about the movement of a closure member of the valve between an open position and a closure position; the member has a reference portion for connection to a fixed portion of the device and a free portion for connection to the closure member, the free portion being movable relative to the reference portion as a result of mechanical deformations produced in the actuating member by the piezoelectric effect. The reference portion of the actuating member is controllable selectively between a condition in which it is locked in a reference position and is fixed firmly to the fixed portion of the device, and a free condition in which it is movable relative to the fixed portion.

摘要： An electromagnetic actuator, particularly for a valve for controlling the injection of fuel or fuel oil is described and comprises: a fixed permanent magnetic core, and an electrical control winding which is disposed in the magnetic field generated by the core and is movable relative to the core when an electrical current flows through the winding, in which the winding is intended to be connected to a movable member actuable by the device, in a manner such as to bring about movement of the movable member between a rest position and at least one operative position. The winding is also arranged to act on the movable member by exerting a resilient force which can hold the member in the rest position or return the member to the rest position.
