Title
(EN) INTERNALLY COOLED POPPET VALVE FOR INTERNAL COMBUSTION ENGINE
(FR) SOUPAPE CHAMPIGNON À REFROIDISSEMENT INTERNE POUR MOTEUR À COMBUSTION INTERNE
Abstract
(EN) It is disclosed a poppet valve (2) with a valve body (4) which has a cavity (6), a coolant inlet port (8), and a coolant outlet port (10); wherein the coolant inlet port (8) and the coolant outlet port (10) are arranged on a valve stem (12) of the poppet valve (2), wherein the cavity (6) extends into the valve stem (12) of the poppet valve (2) and into a valve head (14) of the poppet valve (2), wherein there is provided a coolant conducting element (16) within the cavity (6) and extending into the cavity (6) from the valve head (14) to the valve stem (12), where the coolant conducting element (16) in each case has a cross-section, wherein the coolant conducting element (16) includes a pipe section ( 18) and a funnel section (20), wherein the coolant conducting element (16) extends concentrically to the poppet valve (2) in the cavity (6) of the poppet valve (2).
(FR) L'invention concerne une soupape champignon (2) avec un corps de soupape (4) qui a une cavité (6), un orifice d'entrée de liquide de refroidissement (8) et un orifice de sortie de liquide de refroidissement (10). L'orifice d'entrée de liquide de refroidissement (8) et l'orifice de sortie de liquide de refroidissement (10) sont disposées sur une tige de soupape (12) de la soupape champignon (2). La cavité (6) s'étend dans la tige de soupape (12) de la soupape champignon (2) et dans une tête de soupape (14) de la soupape champignon (2). Un élément conducteur de liquide de refroidissement (16) est pourvu à l'intérieur de la cavité (6) et s'étend dans la cavité (6) de la tête de soupape (14) à la tige de soupape (12) et l'élément conducteur de liquide de refroidissement (16) dans chaque cas comporte une section transversale. L'élément conducteur de liquide de refroidissement (16) comprend une section de tuyau (18) et une section d'entonnoir (20), et (16) s'étend de façon concentrique à la soupape champignon (2) dans la cavité (6) de la soupape champignon (2).
