Title
(DE) HYDRAULISCHER VENTILSTÖSSEL FÜR BRENNKRAFTMASCHINEN
(EN) HYDRAULIC VALVE-TAPPET FOR INTERNAL-COMBUSTION ENGINES
(FR) POUSSOIR DE SOUPAPE HYDRAULIQUE POUR MOTEURS A COMBUSTION INTERNE
Abstract
(DE)
Bei einem hydraulischen Ventilstößel für Brennkraftmaschinen, bestehend aus einem tassenförmigen Gehäuse (1), welches eine hohlzylindrische Wandung (2) umfaßt, soll die Masse des Ventilstößels mit geringstem Aufwand reduziert werden. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Wandung (2) zur Reduzierung der Masse des Ventilstößels mit fensterartigen Durchbrechungen (12) versehen ist.
(EN)
The invention concerns a hydraulic valve-tappet for internal-combustion engines, the tappet having a cup-shaped housing (1) with a cylindrical wall (2). The aim of the invention is to reduce the weight of the tappet in the simplest way. This aim is achieved by virtue of the fact that the wall (2) of the tappet housing is pierced by window-like apertures (12).
(FR)
Dans un poussoir de soupape hydraulique pour moteurs à combustion interne, consistant en un corps en forme de coupe (1), lequel comporte une paroi cylindrique creuse (2), il s'agit de réduire la masse du poussoir de soupape de la façon la plus simple. Selon l'invention, ce but est atteint grâce au fait que la paroi (2) est dotée, pour réduire de la masse du poussoir de soupape, de perçages ajourés (12).
