Abstract
The hydraulic lifter system for variable cylinder engines comprises a hydraulic lifter which is operatively connected to a rocker arm and which includes a body having a pressure chamber and a reservoir chamber, a plunger slidably positioned within the body, and a check valve to allow the fluid flow only into the pressure chamber from the reservoir chamber, a solenoid valve positioned by the side of the hydraulic lifter, means for causing the check valve to open to thereby establish the fluid communication between the pressure and reservoir chambers by means of the solenoid valve, and a stopper member for locking the plunger to stop the operation of the hydraulic lifter in association with the means for causing the check valve to urge to open.
