The invention relates to a hydraulic assembly (10), in particular for supplying a brake circuit of a vehicle brake system with a Fluid at Brake Pressure. Known hydraulic assemblies are equipped with apressure generator (16), but the pressure generator causes pressure fluctuations. In order to suppress pressure fluctuation, a buffer device is used; an annular throttle element of such a damping device is arranged in a gap (72) between a pressure generator and a pump receptacle (14) associated with the pressure generator in a housing block (12) of a hydraulic assembly. According to the invention, a throttle element (70) is proposed, which, in the absence of pressure application, lies on the first support (74a) on the upper side and lies on the second support (74b) on the lower side; the supports (74a, 74b) are formed on opposite side surfaces of the slit (72). According to the invention, the throttle element advantageously cancels a spring element for the axial preloading thereof, is correspondingly compact and cost-effective in design, and can also be easily assembled.
本发明涉及尤其用于为车辆制动设备的制动回路供给处于制动压力下的压力介质的液压总成(10)。已知的液压总成配备有压力发生器(16),然而压力发生器引起压力波动。为了抑制压力波动,使用缓冲装置。已知这种缓冲装置的环形的节流元件布置在压力发生器和分配的用于压力发生器的、在液压总成的壳体块(12)中的泵容纳部(14)之间的缝隙(72)中。提出了节流元件(70),其在没有通过压力加载的状态中以上侧面处在第一支承部(74a)上,并且以下侧面处在第二支承部(74b)上,支承部(74a、74b)构造在缝隙(72)的彼此相对而置的侧面处。节流元件有利地取消了用于其轴向预紧的弹簧元件、与此相应地紧凑地以及成本有利地构建、还可简单地进行装配。
