Title:
CAM SHAFT WITH LUBRICATING OIL SUPPLY FUNCTION
Document Type and Number:
WIPO Patent Application WO/1985/001557
Kind Code:
A1
Abstract:
A hollow portion of a cam shaft (1) contains an elastic packing member (4) which has projections (6) formed on the outer periphery thereof. A lubricating oil passage is defined between the inner peripheral surface of the hollow portion of the cam shaft (1) and the outer peripheral surface of the packing member (4) by the projections (6) which are in close, resilient contact with the inner peripheral surface of the hollow portion. Since the lubricating oil passage has a relatively small volume, during the start of operation, lubricating oil quickly fills into the passage and is supplied to sliding surfaces of cams.
