    • A piston pump (10) for a hydraulic consumer of an electronically controlled vehicle brake system, carries a stepped piston (50, 50′) and centers a sealing assembly (26, 26′) which is retained in an axial direction Ax by a step (52, 52′) on the stepped piston (50, 50′), on the one hand, and is retained by a spring cage (53, 53′), on the other hand. The stepped piston (50, 50′) includes a plane support (54, 54′) for plane support legs (55a,b,c; 55a,b,c′) of the spring cage (53, 53′) The stepped piston (50, 50′) includes radially inwards, with respect to the support (54, 54′), a stepped bore (56, 56′), with the bore (56, 56′) accommodating centering legs (57a,b,c; 57a,b,c′) of the spring cage (53, 53′). Coaxially as well as inside the stepped bore (56, 56′), a spring-loaded valve member (59, 59′) of a non-return valve is arranged. A resetting spring (38) is supported on an abutment (41) of the bushing (18, 19) on the one hand and on the spring cage (53, 53′) on the other hand The bushing (18, 19) is provided with a stop (63, 63′) for the stepped piston (50, 50′), so that stepped piston (50, 50′), resetting spring (38), non-return valve, and sealing assembly (26) are arranged within the bushing (18, 19) as a subassembly that can be handled independently.
    • 一种用于电子控制车辆制动系统的液压消耗器的活塞泵(10)承载有阶梯式活塞(50,50'),并使密封组件(26,26')居中,所述密封组件(26,26')沿轴向方向Ax被保持在步骤 (52,52'),另一方面由一个弹簧笼(53,53')保持在台阶式活塞(50,50')上。 阶梯式活塞(50,50')包括用于弹簧保持架(53,53')的平面支撑腿(55a,b,c; 55a,b,c')的平面支撑件(54,54') 阶梯式活塞(50,50')相对于支撑件(54,54')径向向内包括阶梯孔(56,56'),孔(56,56')容纳定心腿(57a, b,c; 57a,b,c')。 同轴地以及在阶梯孔(56,56')内部,布置有止回阀的弹簧加载的阀构件(59,59')。 另一方面,复位弹簧(38)一方面被支撑在衬套(18,19)的基台(41)上,另一方面支撑在弹簧保持架(53,53')上。衬套(18,19)被设置 具有用于阶梯式活塞(50,50')的止动件(63,63'),从而布置阶梯式活塞(50,50'),复位弹簧(38),止回阀和密封组件(26) 在套管(18,19)内作为可以独立处理的子组件。
