Abstract

외측의 링크형상의 오일 저장실로 부터 중앙의 오일저장실까지 오일을 위한 적어도 하나의 흡입도관이 관통하는 형식의 틈새보상기구를 지닌 태핏에 있어서, 흡입도관(20,33)의 흡입횡단면(21)은, 스커트(3)의 내주면(11)의 근처에, 특히 중력방향으로 볼 때 링크형상의 오일저장실(14)의 가장 낮은 위치근처에 위치하는 영역내에 배치된다. 질량을 현저히 증가시키는 구성부분이 없는 태핏을 제작할 수 있을 뿐 아니라, 모든 운전조건하에서 공기 및 오일의 기포를 흡입하지 않는 액압매체를 중앙의 오일저장실내로 흡입시킬 수 있다.In a tappet having a gap compensator of the type through which at least one suction conduit for oil penetrates from the outer link-shaped oil reservoir to the central oil reservoir, the suction cross-sections 21 of the suction conduits 20 and 33 are , In the region near the inner circumferential surface 11 of the skirt 3, in particular near the lowest position of the link-shaped oil reservoir 14 in the direction of gravity. In addition to producing tappets without components that significantly increase mass, hydraulic media that do not inhale air and oil bubbles under all operating conditions can be sucked into the central oil reservoir.
