Abstract: A pressure relief device usable in a high-pressure fluid circuit for limiting the pressure in the case of a failure of a circuit component is provided, the device includes a body with a pusher sliding therein and axially movable by a spring. A ball seals an orifice connecting a chamber receiving a high-pressure fluid and another chamber. The other chamber includes at least one fluid discharge opening and the ball being held by the spring in a position closing the orifice below a predetermined pressure. The pusher devoid of axial through channels for the fluid, slides in the body and closes at least partially each discharge opening. At least one of discharge openings is connected to an opening also embodied in the body and open at least partially to the opposite side of the pusher.

Abstract: The invention relates to a hydraulic slide valve for controlling flow-rate or pressure comprising at least one movable valve moving from a closed position by contacting a seat and an open position remote therefrom, the displacement of said valve being controlled by a piezoelectric washer.

Abstract: The invention concerns a device for connecting a mechanical, hydraulic and electric connector (1) equipping a heat engine fuel injector to the electromagnet driving the injector, said connector (1) being fixed to a body (2) enclosing the electromagnet and comprising two electric terminals (4) connected to the solenoid (S) of the electromagnet. Said electric terminals (4) are provided each with a pin (15) designed so that when the connector (1) is assembled to the body (2), each pin (15) co-operates with guide means (11, 14) contacting an end portion of the wire (12) of the solenoid (6), the assembling operation resulting in pulling off the insulation in at least one location of said end portion to set up an electrical connection between each terminal (4) and the solenoid (6).

Abstract: Pressure relief device (27) usable in a high-pressure fluid circuit for limiting the pressure in the case of a failure of a circuit component, comprising a body (4) and a pusher (3) sliding therein and axially movable by return means (5) in such a way that it drives sealing means (2) of an orifice (9) connecting an upstream chamber (7) receiving a high-pressure fluid and a downstream chamber (10) which is delimited by the body (4), the side of the pusher (3) and the perforated wall of said orifice (9), said upstream chamber (10) comprising at least one fluid discharge opening (12, 12?) and the sealing means (2) being held by the return means (5) in the position closing the orifice (9) below a predetermined pressure threshold in the upstream chamber (7).
