본 발명은 슬립 제어되는 유압식 차량 브레이크 시스템의 리턴 펌프로서 피스톤 펌프(1)에 관한 것이다. 본 발명에 따라, 버섯 모양의 차단 바디(17)가 스프링 장전형 배출 밸브(14)이고, 그 샤프트(20)는 관형 댐퍼 피스톤(27)의 중앙 홀(21)을 통해 연장한다. 차단 바디(17)는 그 개방 및 폐쇄 방향에 대해 횡으로 이동 가능하므로, 상기 차단 바디는 폐쇄시 밸브 시트(19)에 정렬된다. 개방시, 댐퍼 피스톤(27)은 브레이크 액을, 상기 브레이크 액이 수용되어 있던 댐퍼 챔버(25)로부터 변위시킴으로써, 배출 밸브(14)의 개방 운동이 댐핑된다.

    A piston pump as a return pump of a slip-controlled, hydraulic vehicle braking system is disclosed. There is a mushroom-shaped shut-off body as a spring-loaded outlet valve, the shaft thereof extending through a center hole of a tubular damper piston. The shut-off body is movable transversely to the opening and closing direction thereof, so that said shut-off body aligns with a valve seat upon closing. Upon opening, the damper piston forces brake fluid out of a damping chamber in which it is housed so that an opening movement of the outlet valve is dampened.
