    摘要: A pressure-regulating solenoid valve (100) for a hydraulic circuit for a braking system of a motor vehicle having wheel antilock structure. The hydraulic circuit has at least one pressurized fluid generator (300) connected to a pressure receiver (200) and to a reservoir (400) for retaining fluid at a low pressure. The solenoid valve (100) has an electrical coil (10) which interacts with two pole pieces (12,14), a sleeve structure (28,30) forming a magnetic body (26) which moves under the effect of an actuation force (O) generated by a magnetic field created by the electrical coil (10) and a distributor element (34). The distributor element (34) interacts with the sleeve structure (28,30) in order to command communication between a duct (98) connected to the pressure receiver (200) and a duct (94) connected to the reservoir (400) or a duct (96) connected to the pressure receiver (200). The solenoid valve (100) has at least one reaction chamber (80) which is permanently in communication with pressure chamber (200). The solenoid valve (100) reacts to a reaction force which is added to an actuation force (O) generated by the coil (10) and counter to a force (F) generated by a preloaded elastic means (46,85) on the movable body (26).

    摘要: A proportional solenoid valve for regulating pressure of fluid supplied to a system. The solenoid valve has high-pressure inlet (1), a low-pressure inlet (2) and an outlet (3) through which fluid under controlled pressure is supplied to the system. The solenoid valve has a body (4) with bore (5) therein for retaining a regulating slide valve (9). The regulating slide valve (9) is subjected to a pressure acting on a cross-section (S), to the force of a spring (10) and to a force exerted by an electromagnet (14,15). Movement of the slide valve brings about a communication between the high-pressure inlet (1) and the outlet (3) and communication between the low-pressure inlet (2) and the outlet (3) as a function of a control valve (16). The control valve (16) is located between the high-pressure inlet (1) and the outlet (3) and the high-pressure inlet (1) and low-pressure inlet (2) are isolated from one another by the slice valve (9) as long as said control valve is not open.
