<p>PURPOSE:To reduce the total height of an engine by installing an actuator at a separated position from a tappet part, in a mechanism for varying the number of cylinders in operation by allowing the check valve of a hydraulic type valve gap adjusting mechanism to be inoperative by pressing said valve. CONSTITUTION:An actuator 50 of a solenoid valve which operates a rod 71 for pressing the check ball 72 of a hydraulic tappet 70 is arranged at a position departed from the installation part for the hydraulic tappet 70, and the driving force of the actuator 50 is transmitted to the rod 71 through a cable means 60, hydraulic means, or a vacuum means. Therefore, projection of the actuator 50 from a cylinder cover is prevented, and the total height of an engine can be reduced.</p> |
