Abstract
Between the end of a valve and a valve-operating cam in an internal combustion engine, a valve lifter is inserted. A filler enclosing portion is formed between a shim and the body of the valve lifter. Through an opening from an injector, a filler is introduced into the filler enclosing portion, so that valve clearance is corrected to zero. Differences in valve clearance can be easily corrected.
Claims6
A method of adjusting a valve clearance in a valve operating mechanism, the method comprising the steps of:
- connecting a first member having a valve contacting surface which contacts an end of a valve, with a second member which has a cam contacting surface which contacts a cam for operating the valve, to provide a volume-variable filler enclosing portion between the first and second members to form an intermediate space of a valve lifter;
- providing the intermediate space between the cam and the end of the valve;
- and
- introducing a curable filler into the filler enclosing portion to define a distance between the first and second members to a suitable one to finish the valve lifter.
