摘要： In a fluid-pressure operated anti-skid braking system operation of a brake-applying relay valve (30) is controlled by control pressure in an application chamber (23). A memory chamber (8) is charged on initial brake application, with pressure from a supply passage (44) connected to a brake actuator (3) through a one-way valve (60) and an orifice (64) permits pressure in the memory chamber (8) to decay when the pressure in the supply passage (44) 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 brakes following a skid is controlled by closure of a latch valve (9) which permits only a restricted flow of control pressure into the application chamber (23). This is sufficient to re-apply the brakes rapidly in a first stage until the pressure in the application chamber (23) becomes equal to that of the decayed pressure in the memory chamber (8), 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 (8).

摘要： An anti-skid hydraulic braking system enables a brake (1) on a wheel of a vehicle to be re-applied in two successive stages following correction of a skid, comprising a rapid first stage, followed by a slower, second, stage. This is achieved by a de-boost piston assembly (9) comprising a first piston (10) and a second piston (11)which are movable with respect to a bore (8) and axially with respect to each other, and a control chamber (20) defined between the pistons (10) and (11) and the bore (8) containing hydraulic fluid of which the volume determines the relative positions of the two pistons (10) and (11). The piston assembly (9) incorporates restrictor means (18) for controlling the volume of hydraulic fluid in the control chamber (20) in dependence upon a supply of hydraulic fluid under pressure which normally holds the piston assembly (9) in an advanced, brake-applying position. The first rate of re-apply comprises the two pistons (10) and (11) moving in tandem towards the advanced position until further movement, to determine the second rate, is dependant upon relative movement between the two pistons (10) and (11) as determined by the flow of fluid into the control chamber (20) of fluid under the control of the restrictor means (18), in order to increase the effective volume of the control chamber (20).

摘要： A double solonoid valve (10, 16) especially for anti-lock braking applications has a normally open conduit (12-15) for involving a first port (2) and housed in series with a normally closed conduit (15, 14, 18, 4) between second (3) and third (4) ports. A fast one-way path (19, 37) joins the first and second ports. A slow two-way path (15) always involves the second port. The double valve when used in ABS can handle incipient locking, actual locking, quick releasing to normal after emergency anti-lock action, and purge modes.

摘要： A solenoid-controlled valve of the present invention is provided with a valve housing (12) having first, second and third ports, first and second movable members (68 and 88) housed in the valve housing to freely move along its longitudinal axis, and is made of magnetic material, and a magnetic circuit (M1) for magnetically attracting the first and second movable members independently in order to move them in the direction of the axis. The magnetic circuit includes a solenoid (104), a magnetic flux by-pass (P) for by-passing the second movable member, and a magnetic resistance (R) attached to that portion of the magnetic circuit which is by-passed by the magnetic flux by-pass. The solenoid-controlled valve further has first and second valve members (62 and 92), which are actuated by the movement of the first and second movable members in the direction of the axis to independently open and close the first and second ports.

摘要： A fluid pressure device for operating the brake members (B₁-B₄) of a vehicle with a wheel anti-locking function includes a fluid pressure actuator (40) controlled by a control circuit (10) including sensor means (R₁-R₄) arranged to detect the tendency of the wheels to lock, in order to interrupt the braking action. The pressurised fluid from, for example, the lubrication circuit of the engine and passing through a three-way solenoid valve (48) piloted by the control circuit (10) may act in the sense corresponding to activation or de-activation of the actuator, against the action of a resilient biassing member (55).

摘要： A brake pressure control device for vehicles is provided in a pipeline connecting a master cylinder (22) and a wheel brake (23) with an electromagnetic directional control valve (24) which is switched in a plurality of valve positions by electromagnetic force. The electromagnetic directional control valve (24) is switched between a first valve position and a second valve position. Bidirectional flow of fluid is allowed when the electromagnetic directional control valve is in the first valve position. Unidirectional flow of the fluid is allowed but reverse flow of the fluid is prevented when the electromagnetic directional control valve is in the second valve position.

摘要： A solenoid-operated fluid-flow control valve (11; 45) comprising a single solenoid coil (15; 53), the energisation of which controls the movement of first and second armatures (16 and 17; 56 and 57) which in turn control first and second respective valve means (20, 21, 23 and 27, 28; 70, 71 and 79, 80). The armatures are biassed away from the solenoid by respective springs (18 and 19; 58 and 59), one of which is weaker than the other. When the solenoid is energised by a constant current the armature (16; 56) with the weaker spring (18, 58) is attracted to the end of the solenoid and forms part of a magnetic circuit. This increases the magnetic flux at the other end of the solenoid, allowing the second armature (19; 57) to be drawn to the solenoid sequentially after, and subsequent to, the drawing-in the of the first armature. Particular anti-lock brake systems incorporating the valve are disclosed.

摘要： A hydraulic control device for an anti-skid brake system for a vehicle, including a solenoid-operated directional control valve for communication of a pressure chamber in a hydraulic actuator, selectively with a hydraulic power source and a reservoir, and a solenoid-operated flow control valve disposed between the directional control valve and one of the pressure chamber, hydraulic power source and reservoir, said hydraulic control device being operated to effect rapid and slow rise and fall of a pressure in the hydraulic actuator, in response to a slip ratio of a wheel of the vehicle. The flow control valve comprises a flow restrictor which permits a restricted flow of a fluid through the valve even when its valving member is seated on a valve seat in which a valve hole is open. The flow restrictor is provided in one of various forms except an ordinary orifice with a small diameter. The flow restrictor may be a groove formed in an end face of a valving member opposite to the valve seat, a rough or ragged surface of the valve seat or valving member, or a porous structure formed on the valving member so as to contact the valve seat. Alternatively, the flow restrictor may be formed by a porous structure which fills a hole formed in parallel with the valve hole which is open in the valve seat.
