VALVE STRUCTURE OF AN OVERHEAD-VALVE ENGINE

摘要

The object of the invention is to provide a valve structure for an overhead-valv e engine that it is easy to introduce, with a cylinder head in which the combustio n 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. Positi oned on an inclined plane Ul are the longitudinal center lines 2a, 4a and 1a of the inlet v alve 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.
