摘要： A three-way electrically-operated proportional pneumatic valve including a first inlet (1) connected to a first pressure source (A); a second inlet (2) connected to a second pressure source (D); an outlet (3) connected to a controlled pressure chamber (C); a hollow body (4) receiving the inlets and the outlet for selectively connecting same individually to at least one other inlet and/or outlet; and a solenoid (5) secured to the body and comprising a core (5a) for actuating selective connection members. The selective connection members essentially include a standing valve (6) and a movable valve (7) housed in said hollow body. The standing valve can open when the movable valve is closed, and vice versa, and said valves are defined by a channel (60), a movable tubular sealing member (67) and a solenoid-actuated sealing surface (70). The electrically-operated valve is suitable for controlling the pressure in a chamber (C) according to the pressure from the first and second sources and proportionally to a solenoid control current signal.

摘要： Pneumatic brake servo comprising a reaction member (12) capable of providing a power-assisting force to an input force in order to produce a resulting actuating force. The gain corresponding to the ratio of the actuating force to the input force can be adjusted precisely or over a large dynamic range by varying the stiffness ratio of both springs (16, 20).

摘要： The invention relates to a brake servo comprising a housing (10) containing a piston structure which, by means of a roll-up membrane (12) defines a forward chamber (16) communicating permanently to a vacuum source by means of a valve (17) and a rear chamber (16) selectively communicating with the forward chamber (16) or with the atmosphere by means of a valve (34) upon actuation of a control rod (30), and a device (36) for fixing the servomotor to a wall (38) adjacent to a first face of the housing (10). According to the invention, openings (50, 60) are provided in the structure of the piston (14) and in a second face of the housing (10) and are aligned in the axial direction of the servomotor in oder to enable actuation of the fixing device (36) through the opening (60) in the second face of the housing (10).

摘要： Pneumatic motor vehicle brake servo comprising a shell (10) within which a piston (20) formed from a rear tubular part (22) supporting a skirt (14) defines, by means of an unfolding diaphragm (12), a front chamber (16) permanently connected to a vacuum source and a rear chamber (18) selectively connected to the front chamber (16) or to the atmosphere by a valve means (40) actuated by a control rod (34) capable of bearing, by means of a plunger (32), on one of the sides of a reactive disk (58) mounted on a push-rod (56). The valve means comprises a shutter co-operating by means of an active part (40) with a first valve seat (32a) formed on the plunger (32) and a second valve seat (20a) formed on the piston (20), the shutter (40) being normally urged forwards by resilient means (44). According to the invention, actuating means (60, 100, 160) are provided to urge the active part of the shutter (40) forwards while at the same time co-operating with the first (32a) and second (20a) valve seats.
