Title
(DE) ÖLVERSORGUNGSSYSTEM FÜR VENTILSPIELAUSGLEICHENDE HYDROSTÖßEL
(EN) OIL SUPPLY SYSTEM FOR VALVE CLEARANCE-EQUALIZING HYDRAULIC TAPPETS
(FR) SYSTÈME D'ALIMENTATION EN HUILE POUR POUSSOIRS HYDRAULIQUES À COMPENSATION DU JEU DES SOUPAPES
Abstract
(DE)
Die Offenbarung betrifft ein Ölversorgungssystem (1) für ventilspielausgleichende Hydrostößel (5) eines Verbrennungsmotors, aufweisend • eine erste Versorgungsleitung (10), welche einen Auslass (9) einer Ölpumpe (8) fluidleitend mit einer Baugruppe eines Nockenwellenantriebs verbindet, • eine zweite Versorgungsleitung (20), welche fluidleitend von einer Abzweigung (15) der ersten Versorgungsleitung (10) zu einer Ölgalerie (16) für die ventilspielausgleichenden Hydrostößel (6) führt, • wobei die Abzweigung (15) in einer betriebsbereiten Einbaulage des Verbrennungsmotors oberhalb von der Ölgalerie (16) der ventilspielausgleichenden Hydrostößel (6) angeordnet ist.
(EN)
The invention relates to an oil supply system (1) for valve clearance-equalizing hydraulic tappets (5) of an internal combustion engine, having a first supply line (10), which connects an outlet (9) of an oil pump (8) in a fluid-conducting manner to an assembly of a camshaft drive, a second supply line (20), which leads, in a fluid-conducting manner, from a branch (15) of the first supply line (10) to an oil gallery (16) for the valve clearance-equalizing hydraulic tappets (6), wherein the branch (15) is arranged in an operationally ready installation position of the internal combustion engine above the oil gallery (16) of the valve clearance-equalizing hydraulic tappets (6).
(FR)
L'invention concerne un système d'alimentation en huile (1) pour des poussoirs hydrauliques à compensation du jeu des soupapes (5) d'un moteur à combustion interne. Le système présente • une première conduite d'alimentation (10), laquelle relie une sortie (9) d'une pompe à huile (8) de manière fluidique à un bloc d'un entraînement d'arbre à cames, • une deuxième conduite de liaison (20), laquelle mène de manière fluidique d'une dérivation (15) de la première conduite d'alimentation (10) à une canalisation d'huile (16) pour les poussoirs hydrauliques à compensation du jeu des soupapes (6), • la dérivation (15) étant disposée, dans une position de montage opérationnelle du moteur à combustion interne, au-dessus de la canalisation d'huile (16) des poussoirs hydrauliques à compensation du jeu des soupapes (6).
