Abstract:
1. A pressure-regulating solenoid valve comprising an electromagnetic subassembly provided with a coil and its yoke, associated with a hydraulic subassembly comprising a seat through which a conduit passes linking two fluid circuits, respectively at high and low pressures, means of blocking said conduit, a push rod sliding in a pole piece and operating said blocking means, a moving core joined to the push rod and the displacement of which is controlled by the coil, the electromagnetic and hydraulic subassemblies form two separate unitary blocks, characterized in that said blocks are mounted to rotate relative to each other by assembly, of the hydraulic block in a conduit passing through the electromagnetic block, a locking washer positioned at one end of the electromagnetic subassembly preventing any axial displacement of the hydraulic block in one direction and a shoulder located at the other end of said electromagnetic subassembly preventing any axial displacement in the other direction by contact with an end stop of the hydraulic block, a flexible washer being inserted between the electromagnetic subassembly shoulder and the end stop.
