Combustion chamber seal between cylinder running bush and cylinder head - involves residual surface seal between crankcase and cylinder head and tension force for combustion chamber seal applied by cylinder head screws

摘要

Between a union (8) of the cylinder running bush (2) and an extension (9) of the crankcase (3) a spring ring (10) is fitted, which has a spring characteristic line, which in a predetermined area "B" has a virtually constant spring force over the spring path. The running bush can have a conical sealing surface (6) and the cylinder head (1) has a likewise conical counter sealing surface (7). Between the face surface (11) of the cylinder running bush and the cylinder head, adequate clearance is available. Both the cylinder head and the face surface of the cylinder running bush, viewed in longitudinal section, may have trapezoidal and identical turned-out formations.
