The invention relates to a pneumatic diaphragm brake cylinder (1) for a motor vehicle, comprising a housing part (6) on the pressure side and a housing part (2) facing away from the pressure side, and a diaphragm (24) arranged therebetween, which divides the interior of the diaphragm brake cylinder into two chambers (20, 31) that are hermetically isolated from each other, wherein the first chamber (20) comprises a pressure chamber to which pneumatic pressure is applied and the second chamber (31) comprises a piston chamber for a piston (26) actuated by a diaphragm (24), the peripheral fastening edge (32) of the diaphragm (24) being clamped between the pressure-side housing part (6) and the pressure-facing housing part (2), a pneumatic pressure acts on the diaphragm (24) with respect to a surface (50) on which the working movement of the diaphragm (24) is effective, and a reduction ring (36) is provided, which extends axially from the diaphragm (24) into the housing part (2) facing away from the pressure and radially reduces or radially delimits the effective area (50) of the diaphragm (24), and at least the reduction ring (36) and the diaphragm (24) are designed as a single-piece part.

    本发明涉及一种用于机动车辆的气动膜片制动器缸(1),其具有处于压力侧的壳体零件(6)和背离压力侧的壳体零件(2),以及布置于它们之间的隔膜(24),隔膜将膜片制动器缸的内部分成两个彼此密封隔离的室(20,31),其中第一室(20)包括由气动压力加载的压力室并且第二室(31)包括用于由隔膜(24)致动的活塞(26)的活塞室,其中隔膜(24)的周边紧固边缘(32)被夹持于压力侧的壳体零件(6)与背离压力的壳体零件(2)之间,并且其中气动压力相对于所述隔膜(24)的工作运动有效的表面(50)而加载隔膜(24),并且设置缩小环(36),缩小环从隔膜(24)轴向地延伸至背离压力的壳体零件(2)中并且径向地减小或径向地限制隔膜(24)的有效区域(50),并且至少缩小环(36)和隔膜(24)被设计成单件式部件。
