Abstract
There are output pistonsfor opening intake valves, an intake camcoaxial with a crankshaftto actuate an input piston, a hydraulic control valve, output passagewaysA,B connecting the output pistonsto the hydraulic control valve, and an input passagewayconnecting an input hydraulic chamberto the hydraulic control valve. The hydraulic control valve has one state, which enables pressure-transmission communication between the input passageway and the output passagewayA at least during a period for one cycle of reciprocating motion of the input piston, and another state, which enables pressure-transmission communication between the input passageway and the output passagewayB at least during the period for one cycle of reciprocating motion of the input piston. The hydraulic control valve assumes the states alternately in every rotation of the intake cam
