摘要： In its simplest form, the valve comprises a body with an inlet connector and an outlet connector intended to be connected to a pressure source and a pneumatic circuit respectively. In the body, a valve comprising a seat and an obturator controls communication between the connectors. A control piston is sealingly slidably mounted in the body and, in its working travel, can cause controlled movement of the obturator away from the seat to cause controlled opening of the valve. According to the invention, the seat of the valve is formed in a member mounted in the body for movement in the direction of displacement of the obturator. A member is operatively associated with the piston and intended to cause a displacement of the seat relative to the body together with and in contact with the obturator when the control piston passes beyond a predetermined position relative to the body in its working travel.

摘要： The distributor comprises a body in which a movable brake-operating pusher is mounted for movement as a result of the actuation of the brake pedal. The position of the operating pusher relative to the distributor body is detected by means of a linear potentiometer having a casing fitted into the distributor body and a slide provided with a control pusher adapted to cause the displacement of the slide as a result of the movement of the operating pusher.

摘要： The distributor includes a body with first and second inlet connectors for connection to two pressure sources, and first and second outlet connectors for connection to two separate brake circuits. Communication between the inlet connectors and the outlet connectors is controlled by two valves formed coaxially in the body and provided with a common control device. This device comprises first and second pistons movable coaxially in the body to control the first and second valves. The first piston is movable by means of the operation of the brake pedal and has an extension which extends through an aperture in the second. The latter has an associated spring which biasses it towards the position in which it opens the second valve. First and second reaction members are movable on the extension of the first piston, the first of these cooperating with the second piston and the second being located between the first reaction member and an end retaining head of the extension. Between the reaction members is a spring which urges the first of these towards the first piston and the second against the retaining head. A stop member is provided in the body for stopping the second reaction member relative to the extension of the first piston when the latter is close to the position in which it causes the opening of the first valve, so that further movement of the first piston causes compression of the spring between the reaction members. This spring is therefore not compressed in the initial operating phase of the brake pedal and hence does not provide any reaction to the foot. This spring is compressed only when the opening of the valves is imminent and the consequent reaction transmitted to the foot of the driver is an advantageous indication of the imminence of the opening of the valves.

摘要： A servo-brake-auto-modulator of the kind for use in a trailer provided with a pneumatic braking system is modified so as to enable also the achievement of the functions of an anti-overload valve. To that end a discharge passage (26) which communicates with the atmosphere is formed in an inlet chamber (22) of the body (51) of the servo-brake-auto-modulator (20) in such a position that a control member (47) in one of its working positions, causes a control chamber (33) to be connected to said discharge passage (26), preventing overloading of the parking-brake members (6).

摘要： The servo automodulator is intended for connection to the brake system of the tractor vehicle through a power pipeline, called the automatic pipeline, and a control pipeline called the variable pipeline. This device comprises a body with first and second inlet connectors for connection to the variable pipeline and to the automatic pipeline respectively, an inlet/outlet connector and an outlet connector for connection to a pressure reservoir and to the brake members of the trailer. A non-return valve allows air to flow from the second inlet connector to the inlet/outlet connector to supply compressed air to the reservoir. The body houses a valve system for putting the inlet/outlet connector in communication with the outlet connector when the first inlet connector is supplied with a brake-actuation pressure, and a brake-pressure modulator device which controls the opening of the valve assembly, and hence the brake pressure, in dependence on the load bearing on the trailer. The body also houses a distributor control member which assumes a normal working position, in which it allows communication between the first inlet connector and a control chamber of the brake pressure modulator when the second inlet connector is supplied with pressurized air. The distributor member can move to an emergency position, in which it cuts off communication between the first inlet connector and the said chamber and in which it puts this chamber in communication with the inlet/outlet connector, when the pressure upstream of the non-return valve falls below a predetermined value, for example as a result of rupture of the automatic pipeline.

摘要： The valve comprises a body with an inlet connector and an outlet connector for connection to a pressure source and a pneumatic circuit respectively, and with an obturator valve which controls communication between the connectors. The valve has a control device including a piston sealingly slidable in a guide portion of the body between a first chamber which can be put into communication with a pressure source and a second chamber housing a valve so that the piston can move and open the valve under the effect of the pressure in the first chamber. The guided portion of the piston is generally cylindrical and has a smaller cross-section than the passage cross-section of the guide portion of the body. An intermediate member is sealingly interposed between the guided portion of the piston and the guide portion of the body. The intermediate member has stop means and is locatable between the wall of the body and the guided portion of the piston in the first or second orientations, in which the stop means respectively allow and prevent the movement with the piston under the effect of the pressure in the chamber.
