摘要： A two-stage brake control valve has a larger first stage and a smaller second stage. First stage operates to fill a brake. Then, after a transition phase only the second stage is used to supply the working pressure. A check valve is between the first stage pressure chamber a sump. The check valve opens if the pressure in the first stage pressure chamber exceeds a predetermined value. To minimize the operating force of the valve and to avoid a sudden change of the valve working pressure during the changing phase, the closing force of the check valve is controlled as a function of the valve working pressure. The valve working pressure acts on a valve spool which influences the closing force of the check valve in the way that the closing force decreases with increasing working pressure.
摘要翻译：两级制动控制阀具有较大的第一级和较小的第二级。第一阶段操作以填充刹车。然后，在过渡阶段之后，仅使用第二阶段来提供工作压力。止回阀位于第一级压力室之间的集油槽中。如果第一级压力室中的压力超过预定值，则止回阀打开。为了最小化阀的操作力并避免在变化阶段期间阀工作压力的突然变化，止回阀的关闭力作为阀工作压力的函数被控制。阀工作压力作用在阀芯上，阀芯以闭合力随着工作压力的增加而减小而影响止回阀的关闭力。

摘要： An automobile brake system includes a master cylinder, a wheel cylinder and a solenoid actuated valve between the master cylinder and the wheel cylinder. The solenoid actuated valve is actuatable for maintaining high fluid pressure in the wheel cylinder after a brake pedal associated with the master cylinder has been released in order to prevent unwanted rearward rolling movement of a vehicle once it has stopped.

摘要： A piston defines in a cylinder housing a pressure chamber connected to a brake pipe and a fluid supply chamber connected to an oil reservoir. The piston has a recess facing the pressure chamber at one end thereof. A valve member is provided in the recess for making or breaking fluid communication between the pressure chamber and the oil reservoir through the supply chamber. A compression spring is disposed in the recess for urging the valve member into its closed position. A spring retainer is fitted about the end of the piston for holding the spring in the recess. A supporting member is provided in the housing on the opposite side of the pressure chamber from the piston. The valve member is supported by a connecting rod extending axially movably through the spring retainer and the supporting member. A compression spring is connected between the spring retainer and the supporting member for urging the connecting rod in the direction which causes the valve member to open. The spring retainer is movable axially of the piston, while the supporting member is fixed to the housing.
