摘要： A hydraulic braking system is provided in which the speed of increase of the hydraulic pressure to the wheel cylinders is controlled so that appropriate braking force is ensured while at the same type preventing the road wheels from being positioned in a lock-up condition. In order to provide for such an operation, the locking condition of the road wheels may be detected during braking operation and the anti-lock control system operated so that changeover valves are positioned by a control system so that output pressure of a hydraulic booster is applied to the anti-lock control valves and to the flow control valves so as to appropriately changeover between one of two operating positions in response to the locking condition of the road wheel. In order to provide for such fluid communication of the braking system, a multi-stage orifice arrangement is provided in connection with the anti-lock control valves and the flow control valves.

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： A fluid pressure controlling solenoid valve is disclosed for producing an oil pressure which drives a brake pressure controlling piston in a manner such that an brake oil pressure applied to the brakes associated with wheels in response to the depression of a brake pedal is adjusted to a low value in order to prevent a high slip ratio of wheels with respect to a road surface and to a high value when the slip ratio is reduced. A switching solenoid valve is assembled on the upper end face of an intermediate member formed of a magnetic material and having a first fluid path extending therethrough from its upper to its lower end face for selectively connecting the first fluid path with a reduced pressure input port and a high pressure input port. A switching solenoid valve which opens or closes the connection between the first fluid path and the output port is assembled on the lower end face of the intermediate member. The solenoid valve has an orifice of a reduced diameter which maintains a communication between the first fluid path and the output port.

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, the 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.

摘要： An anti-lock solenoid valve mechanism which includes a fluid pressure differential member for controlling the flow rate of fluid through the mechanism when the latter is energised. This member is displaced against the armature by the pressure differential across it due to fluid flow past it and displaces the armature against the solenoid magnetic force towards its closed position to reduce fluid flow until a state of equilibrium exists in which the armature is held by the resultant forces in a position in which it has to undergo only minimal displacement to close the solenoid valve on de-energisation.

摘要： A vacuum-actuated adaptive braking modulator provides a nonlinear brake pressure build curve without requiring a multiplicity of solenoid valves. The device includes the usual diaphragm slidably mounted within a housing and which defines a pair of compartments between opposite sides of the diaphragm and corresponding ends of the housing, and a slow pressure bleed orifice extending through the diaphragm that permits restricted fluid communication from one compartment to the other during a brake pressure build operation. The diaphragm includes a flexible resilient portion which interconnects the rigid portion of the diaphragm to the wall of the housing. A plurality of passages in addition to the slow bleed orifice extend through the rigid portion of the diaphragm to communicate one of the chambers with the other. When the diaphragm is disposed in an extreme actuated position, the flexible portion of the diaphragm is moved away from the passages to permit fluid communication through the latter between the chambers. However, as the diaphragm moves in the return direction, the diaphragm progressively closes the passages, thereby reducing the size of the total area of the passages communicating the chambers with one another, and thereby reducing the rate at which the diaphragm moves. Since the brake pressure build rate is governed by the rate of movement of diaphragm, the brake pressure build rate will be relatively large when the diaphragm is disposed in the extreme actuated position, and will be progressively reduced as the diaphragm moves in the return direction.
摘要翻译：真空致动的自适应制动调制器提供非线性制动压力建立曲线，而不需要多个电磁阀。该装置包括可滑动地安装在壳体内并且在隔膜的相对侧和壳体的相应端部之间限定一对隔室的通常的隔膜，以及延伸穿过隔膜的缓慢的压力泄放孔，其允许从一个隔室到另一个在制动压力建立操作期间。隔膜包括柔性弹性部分，其将隔膜的刚性部分与壳体的壁相互连接。除了缓慢排出孔之外，多个通道延伸穿过隔膜的刚性部分，以将一个室与另一个连通。当隔膜设置在极端致动位置时，隔膜的柔性部分从通道移开，以允许通过腔室之间的流体连通。然而，当隔膜在返回方向上移动时，隔膜逐渐关闭通道，从而减小了将腔室彼此连通的通道的总面积的尺寸，从而降低隔膜移动的速率。由于制动压力建立速度由隔膜的移动速度决定，因此当隔膜设置在极致动位置时，制动压力的建立速度将相对较大，随着隔膜沿返回方向的移动，制动压力的建立速度也会相对较大。

摘要： The invention provides more gradual and typically more linear response to an abrupt change of command force in a pressure regulating valve, in which the command force is opposed by a hydrostatic force developed from the output pressure and any lack of balance operates a control valve to supply fluid to or from the outlet to reestablish equilibrium. A flow limiting orifice is inserted between the control valve and the output, and the hydrostatic force is developed in part directly from the pressure at the output and in part from the pressure in the space between the control valve and the orifice. The effective size of the flow limiting orifice is preferably variable in response to the degree of opening of the control valve. The described structure is particularly useful in a pressure regulating valve in an antiskid brake control system.

摘要： In an active brake pads retraction system, the improvement is a metering check valve which limits the retraction. The metering check valve is interfaced with an anti-lock brake system (ABS), disposed in the hydraulic brake line between the brakes apply system of the ABS and a caliper member of the ABS located at each brake corner. Brake pads are retracted with respect to the brake rotor responsive to predetermined conditions of the motor vehicle in which braking is not required, wherein a retraction volume within the metering check valve limits the amount of brake pads retraction.
