The object of the invention is to provide a valve structure for an overhead-valve engine that it is easy to introduce, with a cylinder head in which the combustion chamber is hemi-spherical. The inlet valve 3 and exhaust valve 2 are positioned in such a manner that they incline substantially in a "V" formation as seen in front view. Positioned on an inclined plane Ul are the longitudinal center lines 2a, 4a and 1a of the inlet valve 2, the associated push rod 4 and the rocker arm 1, which connects these, respectively. Positioned on an inclined plane U2 are the longitudinal center lines 3a, 4a and 1a of the exhaust valve 3, the associated push rod 4 and the rocker arm 1, which connects these, respectively.
La présente invention a trait à la disposition des soupapes d'un moteur à soupapes en tête. D'application facile, cette invention comporte également une culasse dans laquelle la chambre de combustion est hémisphérique. La soupape d'admission (3) et la soupape d'échappement (2) sont placées de telle sorte qu'elles sont inclinées essentiellement pour former un « V » lorsqu'elles sont vues de face. Les lignes centrales longitudinales (2a, 4a, et 1a) de la soupape d'admission (2), la tige poussoir (4) correspondante et le culbuteur (1), qui les relient respectivement, sont disposés selon un plan incliné (U1). Les lignes centrales longitudinales (3a, 4a et 1a) de la soupape d'échappement (3), la tige poussoir correspondante (4) et le culbuteur (1), qui les relient respectivement, sont disposés selon un plan incliné (U2).
