Abstract: A solenoid valve device with a pressure-responsive slide mechanism, including: a body including at least three channels for flow of a liquid; a slide that can be moved in the body by a pressurised fluid, between a position with fluid communication between a first and a second channel among the three flow channels, and a position with fluid communication between the second channel and the third channel; a selector for selecting an activation threshold for movement of the slide, among at least one first and at least one second pressure threshold; and a regulator for regulating at least the activation thresholds of the slide.

Abstract: A piston valve includes a body, a valve seat, an obturator in the form of a piston and a return spring. The body includes an envelope provided with at least one outlet orifice for the pressurised fluid, and an interior element that is attached in the envelope. The interior of the body carries the valve seat and provides the translational guidance of the obturator in the body. Furthermore, the interior element includes at least one window configured to guide the fluid from the valve seat towards the outlet orifice.

Abstract: A lubricating nozzle comprising a metal spray nozzle body comprising a contact surface, the spray nozzle body comprising an axial channel opening out onto the contact surface, a retaining screw, and an orienting plate. The spray nozzle body is mounted inside the hole such that it abuts against a first face of the orienting plate, and such that the contact surface of the body is flush with a second face (106b) of the orienting plate opposite the first face, the spray nozzle body and the orienting plate (106) comprising a first complementary orienting structure which engages such that the oil outlet is oriented, according to a predetermined orientation relative to the first orienting structure, the orienting plate (106) further comprising a second orienting structure designed to orient the plate on the engine block.

Abstract: Cooling spray jet comprising a supply inlet, a discharge outlet, a reaming connecting the inlet and the outlet, the outlet having a given cross-sectional area, a valve comprising a plug free to slide in the reaming and bearing in contact with a valve seat in a closed state. The valve has two open states after a first phase in which the plug separates from the valve seat, with different ranges of fluid pressures, the cross-sectional area between the plug and the reaming of each opening state being different from the cross-sectional area of the other state, one of these opening states having a cross-sectional area that regulates the fluid flow at the discharge outlet and the other opening state having a cross-sectional area such that the flow is regulated by the cross-sectional area of the outlet.

Abstract: Device for controlling the supply of a system from a pressurised fluid source comprising an inlet (8), an outlet (10) of pressurised fluid, a main duct (11) connecting the inlet (8) and the outlet (10), and control means comprising: a secondary duct (12) connecting the supply inlet (8) to the evacuation outlet (10), a moving sealing element (14) interrupting the flow in the main duct (11), a sealing device able to interrupt the flow in the secondary duct, a pilot chamber (18) between the moving sealing element (14) and the sealing means, connected to the inlet (8). In a closed state of the sealing device, the moving sealing element (14) interrupts circulation of the fluid between the inlet (8) and the outlet (10), and, in an open state of the sealing device, the moving sealing element enables flow between the inlet (8) and the outlet (10).
