Abstract
A sealed-type lash adjuster includes a cylindrical body; a plunger received in the body and forming a chamber with the bottom of the body; and a diaphragm mounted between an open end of the body and the plunger, and forming a reservoir for hydraulic oil to be supplied to the chamber. The adjuster also includes a holder having a bushing for receiving the body with the bottom of the body engageable with a valve rocker, and the diaphragm and the open end of the body generally facing away from the combustion chamber, a reservoir for storing fluid lubricant, and a conduit for conducting fluid lubricant from the reservoir to an interior annular channel in the bushing. At least part of the thickness of the diaphragm is formed of a fluorine-bonded layer extending over the entirety of the diaphragm.
