摘要： A known hydraulic vehicle brake system has an anti-skid valve assembly. By this assembly, the at least one wheel brake can be temporarily disconnected from the master brake cylinder and connected to one inlet of a return pump, which furnishes the quantities of pressure fluid flowing out of the wheel brakes both to a damper chamber and, via a damper throttle, to the master brake cylinder and/or the at least one wheel brake. The disadvantage is that all of the pressure fluid pumped by the return pump can sometimes reach the master brake cylinder, disagreeably moving the brake pedal in the direction of its outset position. This can annoy a driver and should be avoided. The improved vehicle brake system has a valve, which in anti-skid operation can be blocked, located between the damper throttle and the master brake cylinder and also has a bypass throttle bypassing the valve. As a result, during anti-skid operation, the brake pedal is not displaced to such an annoying extent.

摘要： A vehicle brake system comprising a hydraulically controllable 2/2-way valve, which has a first control inlet and a second control inlet. The first control inlet receives its control pressure from a first brake pressure source, while the second control inlet contrarily receives its control pressure from a second brake pressure source, such as a so-called return pump apparatus. The vehicle brake system can be used in passenger cars, vans, small buses, and small trucks as well as motor cycles.

摘要： A damping device for pressure pulsations having a first hollow chamber for receiving hydraulic pressure fluid and a second hollow chamber. An elastic metal diaphragm that divides the second hollow chamber hermetically from the first hollow chamber. The second hollow chamber is evacuated, so that in the event that the metal diaphragm should possibly leak, no air can get into the hydraulic pressure fluid. The damping device can be used in hydraulic brake systems having a master cylinder and in other hydraulic systems.

摘要： The brake system has at least one valve assembly, disposed between a master brake cylinder and at least one wheel for controlling the brake pressure during anti-skid operation. A pump is also provided for pumping pressure fluid, withdrawn from the wheel brake during a pressure reduction phase, to the master brake cylinder. A valve assembly comprising two parallel-connected 2/2-way valves is provided between the master brake cylinder and the pressure control valve assembly. During anti-skid operation, the first 2/2-way valve can be switched into a position (b) that throttles the flow of pressure fluid both from the pump to the master brake cylinder and from the master brake cylinder to the wheel brake. As a result, pulsations at the brake pedal of the master brake cylinder are largely avoided. The second 2/2-way valve, which can be switched by the pressure in the master brake line into its switch position (b) that blocks the flow path, can be switched over upon termination of the braking event into its switch position (a), in which its flow path is open and rapid brake pressure reduction is enabled. The second 2/2-way valve is likewise capable of being switched over into its switch position (a) whenever inadmissibly high pumping pressures are in effect.
摘要翻译：制动系统具有至少一个阀组件，设置在主制动缸和至少一个车轮之间，用于在防滑操作期间控制制动压力。还提供泵，用于将在减压阶段期间从车轮制动器抽出的压力流体泵送到主制动缸。在主制动缸和压力控制阀组件之间设置有包括两个并联的二通阀的阀组件。在防滑操作期间，第一个二位二通阀可以切换到一个位置（b），该位置（b）可以将泵从主制动缸和主制动缸的压力流量节流到车轮制动器。因此，主制动缸的制动踏板的脉动大大地被避免。可以通过主制动管路中的压力切换到阻塞流路的开关位置（b）的第二个二位二通阀在制动事件终止时切换到其开关位置（a ），其中其流动路径打开，并且能够快速制动压力降低。第二个2/2通阀同样能够在不可避免的高泵送压力有效时切换到其开关位置（a）。
