摘要： An integral valve body of elastic material for use in the multiple function valve of a vacuum-operated brake power booster has two roughly circular cylindrical parts which are arranged one behind the other. Two annular portions of the valve body which succeed the cylindrical parts are formed to be particularly rigid. A bellows portion which forms a roll fold and interconnects the annular portions has an S-shaped longitudinal sectional profile in the longitudinal direction of the valve body, the profile being comparatively thin-walled.

摘要： Pressure control devices with a valve connected between an inlet chamber and an outlet chamber and a non-return valve operating as a by-pass are known. The non-return valve opens due to a reduction in pressure in the inlet chamber relative to the pressure in the outlet chamber against a closing force. This type of known pressure control devices are very expensive to manufacture and are not safe against failure and great erosion. According to the present invention a single arrangement providing the valve and the non-return valve comprises a tappet with a valve body fixed thereto to provide the operation of both valves. The valve body is essentially cylindrical and elastic and its outer surface is spaced from the inner surface of the outlet chamber. The outer surface of the valve body is armored in such a way that a deformation in the radial direction toward the inner surface of the outlet chamber is avoided.
摘要翻译：具有连接在入口室和出口室之间的阀和作为旁路操作的止回阀的压力控制装置是已知的。由于入口室中的压力相对于出口室中的压力相对于关闭力而减小，止回阀打开。这种已知的压力控制装置制造成本非常昂贵，并且不能防止故障和大的侵蚀。根据本发明，提供阀和止回阀的单一布置包括具有固定到其上的阀体的挺杆，以提供两个阀的操作。阀体基本上是圆柱形和弹性的，其外表面与出口室的内表面间隔开。阀体的外表面以这样一种方式铠装，使得避免了径向向出口室内表面的变形。

摘要： In prior art vacuum brake boosters embodying a two-stage reaction, the magnitude of the two-stage reaction is limited because of the small space available for the reaction-delaying spring. Moreover, the lost motion present in the reaction lever mechanism has to be overcome when the braking operation is initiated. These disadvantages are overcome in a vacuum brake booster including a reaction mechanism constructed in accordance with the present invention wherein the reaction-delaying spring is positioned on the side of the reaction levers adjacent the vacuum chamber and by having the point of contact of the spring on the reaction levers at a greater radius than the point at which the levers are in engagement with the movable wall.
摘要翻译：在现有技术中体现两级反应的真空制动助力器中，由于反应延迟弹簧的可用空间小，两级反应的大小受到限制。此外，当制动操作开始时，必须克服反作用杆机构中存在的空动。在包括根据本发明构造的反作用机构的真空制动助力器中克服了这些缺点，其中反作用延迟弹簧位于靠近真空室的反作用杆的侧面上，并且通过使弹簧的接触点该反作用杆的杠杆比可操作的壁处于更大的半径处。
