    摘要： The present inventive relates to a master cylinder (1 ) with elastomeric central valves (20) which can be opened in opposition to a relatively high pressure in the pressure chambers (8 and 9) without damage. The sealing face (29) of the valve member (26) is in the form of a hollow cylinder protruding slightly from the broad head portion (24) of the valve pin (21). The valve member sealing face does not, as has been conventional practice, extend radially inwardly past the head portion (24) in the direction of the central bore (13) to avoid being drawn into the bore (13).

    摘要： The invention relates to a master cylinder, in particular for a hydraulic brake system, with at least one pressure chamber formed in a housing of the master cylinder and at least one reservoir bore for accommodating a pressure fluid reservoir, a valve with a closing element being provided which due to a pressure difference prevailing between the pressure chamber and the pressure fluid reservoir can be moved into an opening position or a closing position, the valve in its opening position allowing a pressure fluid flow from the pressure fluid reservoir into the pressure chamber and throttling or preventing, in its closing position, a pressure fluid flow in the opposite direction to the pressure fluid flow from the pressure chamber into the pressure fluid reservoir. In order to allow not only a reduction of the lost travel of the master cylinder but also a vacuum filling of the brake system, means are provided which maintain the closing body in its opening position when it is acted upon by a closing pressure difference due to an evacuation for the purpose of vacuum filling of the brake system and allow the closing element to move in its closing position when the brake is actuated.

    摘要翻译： 本发明涉及一种主缸，特别是用于液压制动系统，其中至少一个压力室形成在主缸的壳体中，以及至少一个储存孔，用于容纳压力流体储存器，具有闭合元件的阀 由于压力室和压力流体储存器之间的压力差可以被移动到打开位置或关闭位置，阀处于其打开位置，允许压力流体从压力流体储存器流入压力室， 在其关闭位置节流或防止与从压力室进入压力流体储存器的压力流体流相反的方向上的压力流体流动。 为了不仅能够减少主缸的损失行程，而且允许减小制动系统的真空填充，所以提供了当闭合体处于由开启位置起作用的闭合压力差时将闭合体保持在其打开位置的装置 用于真空填充制动系统的疏散，并且当制动器致动时允许闭合元件在其关闭位置移动。
