摘要： A valve drive device for an engine include a valve for opening or closing an opening of a port to a combustion chamber, a valve drive member for opening or closing the valve and a drive shaft for driving the valve drive member. The device also includes a variable valve timing mechanism for continuously changing a working angle of the valve corresponding to an operation state of the engine by changing a state of drive force transmission from the drive shaft to the valve drive member. A variable valve clearance mechanism is configured such that a valve clearance that is defined as a gap between the valve and the valve drive member can be set at a first value during a first condition in which the working angle of the valve is large to a second different value during a second condition in which the working angle of the valve is small.

摘要： A valve drive mechanism for actuating a valve of an internal combustion engine includes a cam member with a cam surface having a first portion and a second portion. A roller is configured to rotate and contact the first portion of the cam surface when the valve is in a closed position and the second portion of the cam surface with the valve is in an open position. The cam member and the roller are configured to reciprocally move relative to each other to open and close the valve. When the roller contacts the first portion, a gap within the valve drive mechanism exists between components of the valve drive mechanism on a downstream side of a force transmission path to the valve with respect to a contact point between the roller and the cam surface. A spring member urges the roller and the cam surface into contact with each other during motion between the cam member and the roller.

摘要： A rotational cam can be disposed on a camshaft rotationally driven by a crankshaft of an internal combustion engine. A swing cam can be swingable through the rotational cam. The swing cam has a rotational cam abutment portion which contacts the rotational cam and transmits driving force from the rotational cam to the swing cam. An abutment portion displacing mechanism can be provided for displacing the rotational cam abutment portion to change a relative distance between the rotational cam abutment portion and a center axis of the swing shaft. Changing the relative distance allows changing a lift and the like of a valve.
