Hydraulic valve lash adjuster

摘要

The lash adjuster body has a piston in a closed bore. A cam is in communication with one surface of the assembly for imparting motion to it. The assembly has a fluid reservoir and chamber formed within it. The chamber is formed between the bore bottom surface and the bottom surface of the piston. A valve opening (64) is also formed for providing fluid communication between the reservoir and the chamber. A check valve mechanism is in communication with the valve opening for selectively opening and closing the valve opening in response to the angular position of the cam.
