A device that eliminates the need for mechanical clearance in
the valve train of internal combustion engines. Clearance is
normally required to prevent the valve's being held open and
destroyed as the valve train undergoes thermal expansion. However,
clearance requires frequent adjustment and is responsible for much
operating noise. The hydraulic lifter is a telescoping compression
strut in the linkage between cam and valve, consisting of a piston
and cylinder . When no opening load exists, a weak spring
moves the piston, extending the strut and eliminating any
clearance. This action sucks oil into the cylinder past a check
valve. The trapped oil transmits the valve-opening forces with
little deflection. A slight leakage of oil during lift shortens the
strut, assuring valve closure. The leakage oil is replaced as the
spring again extends the strut at no load. It is suitable
for audi and volkswagen.
