Abstract

PURPOSE: To absorb the cubical expansion of oil and maintain tight sealing of an automatic valve clearance controller fitted between a can and push rod of a valve mechanism in an OHV type internal combustion engine, by increasing the effective area of its elastic seal.
CONSTITUTION: A plunger 17 is inserted loose in a cylindrical lifter 16 which is in touch with a cam to compose an oil chamber 18. A heat resisting, elastic seal 30 is put between the internal wall of the lifter and the small bore end 17a to absorb the cubical expansion of oil. A ball seat for receiving the lower spherical surface of a push rod is fitted to the upper end of the small bore 17a and fixed with a fastener 33. Since a ball seat 32 is independent from the small bore 17a, it is possible to reduce the small bore 17a and expand the seal 30, irrelevant to the size of its concave 32a. Oil flowing along the push rod lubricates the fastener 33 through a hole 34 to reduce rattling and abrasion.
