ABSTRACT:
A valve timing adjusting mechanism houses a timing adjusting gear assembly within a liquid-tight housing which prevents working fluid used to adjust the timing from coating a timing gear engaging a timing belt. The working fluid is introduced within the housing to exert timing adjusting force on the timing adjusting mechanism, resulting in relative angular displacement between a camshaft and the timing gear which is manifested as an adjustment to the valve timing. With this arrangment, the timing belt is free of working fluid. Therefore, the lifetime of the belt retains its design value and slip between the timing belt and the timing gear can be prevented.
