Internal combustion engine with hydraulic valve clearance adjustment elements and an oil supply for these

摘要

In an internal combustion engine, the valves of which are actuated by a camshaft (1) by way of bucket tappet-like valve clearance adjustment elements (7) supported in guides (6), longitudinal and transverse passages (16, 21) in the camshaft (1) and bearing bolt holes (11) for camshaft bearings (3, 5) serve for the transport of oil to the individual adjustment elements (7). In order to avoid the need for a separate bearing body (3) in addition to the cylinder head for making feed passages between the bearing bolt holes (11) and the guides (6), the axes (9, 24) of adjacent guides (7) and bearing bolt holes (11) run in a transverse direction at an angle so that notches (15) are produced between the two (Fig. 1). <IMAGE>
