Abstract
A hydraulic valve lifter for variable displacement engine includes a valve housing, one-way valve disposed in the housing for controlling fluid communication between a working chamber and a reservoir, a sleeve member secured to one end of the valve housing and an axial bore therein and a plunger slidably disposed in the axial bore of the sleeve member. The outer diameter of the plunger is designed to be smaller than the inner diameter of the valve housing so that the inertia weight of the plunger may be reduced.
