摘要： In an anti-lock braking system incorporating a solenoid-operated fluid flow control valve, the rate at which fluid can normally be dumped to release a brake is increased by the provision of a pilot valve. The pilot valve is adapted to open by a pressure drop across a diaphragm. The pressure drop is established when an exhaust valve opens upon energization of the solenoid in response to an anti-lock signal.

摘要： An anti-lock (ABS) hydraulic braking system for vehicles comprises a first normally open solenoid-controlled valve (4) disposed in a line between a master cylinder (3) and a brake (1), a second normally closed solenoid-controlled valve (8) disposed between the brake and expander chamber (7), and a normally-open solenoid-controlled by-pass valve (5) located between the master cylinder and the brake and by-passing the first solenoid-controlled valve (4). The by-pass valve (5) is movable between a normally open position to provide unrestricted communication between the master cylinder and the brake, and a closed position in response to an anti-lock signal accompanied by closure of the first solenoid-controlled valve (4) and opening of the second solenoid-controlled valve (8), the by-pass valve remaining closed in a given brake application cycle with the brake being re-applied at a rate determined by flow through the first solenoid-controlled valve (4) following closure of the second solenoid-controlled valve (8).

摘要： A trailer air braking system has combined spring brake and service brake actuators, and the service brake chambers of the actuators are controlled by a combined emergency relay and modulator valve assembly of known construction. In order to ensure that the spring brake function does not become operative due to a moderate loss in the pressure of the trailer reservoir, such as would occur in the event of an anti-skid test in which the reservoir is isolated from the emergency line and the modulator valve is cycled, a spring brake one-way control valve is inserted into the spring brake circuit leading from the reservoir. The control valve acts in one condition as a one-way valve to prevent air returning from the spring brake actuator chamber to the reservoir, but on a large loss in reservoir pressure, a piston which carries the one-way valve seat and is subjected to reservoir pressure moves under spring biassing such that the one-way poppet valve member is unseated by a control pin to permit a reduction in spring brake pressure.

摘要： A trailer braking system for a towing vehicle has a trailer braking valve (26) is fed with a pressurized air supply which is modulated by the opening of the valve, as controlled by a first control pressure regulated by a trailer braking controller (24) in accordance with braking demand signals, to produce a trailer braking pressure. In order that a trailer braking pressure may be generated even if the above trailer braking valve control fails, the valve is supplied with a second control pressure independently of the first, and which is also capable of operating the trailer braking valve (26). In a preferred embodiment, the second control pressure is supplied from a braking line of the towing vehicle, such that the "back up" control pressure is a function of the towing vehicle braking.

摘要： Brakes (1,2; 3,4) on the wheels (5,6; 7,8) at opposite ends of a common axle are each controlled by a separate skid control unti and a single latch valve (21) common to both units closes at the first skid point to be sensed by a sensor (9,10; 11,12) on either wheel. A control module (13) responsive to signals from at least one of the sensors is operative to operate the latch valve and the skid control unit for the respective wheel. When a skid-signal is detected from a sensor on only one wheel the latch valve closes and the brake on the skidding wheel is released and re-applied when the skid signal terminates. The brake is re-applied in a fast first stage, due to pressure from an associated memory chanber and thereafter in a slower second stage due to the latch valve restricting the increase of braking pressure when it is closed. The rate of increase of brake pressure of the non-skidding wheel is restricted to that of the slow stage from the time that the latch valve is closed due to the other wheel skidding. The pressure in the memory chamber can decoy during a skid to compensate for pressure build up elsewhere in the system and so ensure that the pressure to which the brakes are applied in the first stage of brake re-application is not more than that at which the skid occurred.

摘要： Brakes (3, 4) on the wheels (7, 8) on a common axle are each controlled by a separate skid control unit (16, 17) each including a memory chamber (33, 34), and a single latch valve (21) common to both units closes at the first skid point to be sensed by a sensor (11, 12) on each wheel. The rate of re-application of the two brakes is controlled in response to signals from the individual sensors, but at rates of pressure increase determined by each respective memory chamber, and by flows of pressure controlled by restrictors (47).

摘要： In a fluid-pressure operated anti-skid braking system operation of a brake-applying relay valve is controlled by control pressure in an application chamber. A memory chamber is charged on initial brake application with pressure from supply passage connected to a brake actuator through one-way valve and an orifice permits pressure in the memory chamber to decay when the pressure in the supply passage reduces. This reduces the effective volume of air required for initial operation of the relay valve thereby increasing its response time. Re-application of the brake following a skid is controlled by closure of a latch valve which permits only a restricted flow of control pressure into the application chamber. This is sufficient to re-apply the brakes rapidly in a first stage until the pressure in the application chamber becomes equal to that of the decayed pressure in the memory chamber, whereafter brake re-application continues at a slower rate since the restricted flow of control pressure has also to increase the pressure in the memory chamber.
摘要翻译：在流体压力操作的防滑制动系统中，制动施加继动阀的操作由施加室中的控制压力控制。在通过单向阀连接到制动致动器的供应通道的压力下，在初始制动施加时对存储器室进行充电，并且当供应通道中的压力减小时，孔口允许存储器室中的压力衰减。这降低了继电器阀的初始操作所需的空气的有效体积，从而增加了其响应时间。通过闭合闭锁阀来控制制动器在滑动之后的再次施加，该闭锁阀仅允许限制的控制压力流入施加室。这足以在第一阶段快速重新施加制动器，直到施加室中的压力变得等于存储室中的衰减压力的制动重量，此后制动器再次施加以较慢的速度继续进行，因为控制流程压力也增加了存储室中的压力。

摘要： A dual brake valve assembly including two co-axial primary and secondary valves for primary and secondary braking circuits is modified to include an auxiliary exhaust valve operable in conjunction with the pressure plate and a secondary piston for controlling operation of the secondary valve in response to operation of the primary valve. When the valve assembly is operated to apply the brakes, the auxiliary exhaust valve remains closed to prevent the premature release of fluid from the primary circuit irrespective of uncontrolled relative movement between parts of the valve assembly.
