弁駆動装置。 A cam provided on a camshaft that rotates in synchronization with the crankshaft of an internal combustion engine and a piston in contact with the cam are housed in a cylinder so as to be able to reciprocate, thereby defining a fluid chamber filled with incompressible fluid. an actuator that defines a fluid chamber filled with incompressible fluid and communicating with the fluid chamber of the hydraulic generator; In the valve driving device for an internal combustion engine, the valve drive device is capable of reciprocating movement in the same direction as the piston within its cylinder and is in contact with one of the hydraulic generator or actuator with a gap in the reciprocating direction between the piston and the piston. 1. A valve drive device for an internal combustion engine, which houses a member and includes a compression spring interposed between the corresponding contact member and the piston.
