The pressure controlling electromagnetic valve comprises an electric sub-assembly (1) provided with a coil (3) and the yoke thereof (4) associated with a hydraulic sub-assembly (2) provided with a seat (7), which a conduit (9) connecting two high and low-pressure fluid circuits (10, 11), respectively, passes through, sealing means (8) of said conduit (9), a pusher (12) sliding in a pole piece (19) and actuating said sealing means (8), a movable core (13) which is connected to the pusher (12) and whose displacement is controlled by the coil (3), wherein said electric (1) and hydraulic (2) sub-assembly form two distinct unit blocks. Said blocks are rotatably mounted with respect to each other by assembling the hydraulic block (2) in the conduit, which passes through the electromagnetic block (1), a locking washer (23) is arranged on an end of the conduit for preventing any axial displacement of the hydraulic block (2) in one direction and a shoulder (27) is arranged on the other end of said conduit for preventing the displacement of said hydraulic bloc (2) in the other direction by contacting the limit stop (18) thereof and a elastic washer (26) is inserted between the shoulder (27) and the limit stop (18).
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.
