摘要： A variable valve mechanism of an internal combustion engine includes a cam, a transmission mechanism, a first variable device that controls the transmission mechanism to continuously change at least a maximum lift amount of a lift curve indicating a lift amount of a valve that corresponds to a rotation angle of the internal combustion engine, and a second variable device that controls the transmission mechanism to continuously change at least an operation angle of the lift curve. When the lift curve lies in any condition within a predetermined range that covers all or part of a variable range of the lift curve, an absolute value of a ratio of a maximum lift amount variation to an operation angle variation for a slight change from the condition caused by the first variable device is larger than that for a slight change from the condition caused by the second variable device.

摘要： A variable valve mechanism of an internal combustion engine includes an input arm, an output arm, a lock pin, a drive device and a return spring of the lock pin, and a lost motion spring of the input arm. The input arm has in its rear end portion a pushback surface and a stopped surface. The lock pin has in its distal end portion a pushed-back surface and a stopping surface. The drive device includes a driving source and a mover that moves to push the lock pin when driven by the driving source. A driving force of the driving source is set so as to be smaller than a force with which the pushback surface pushes back the pushed-back surface as the lost motion spring causes the input arm to freely swing upward and be larger than load with which the return spring displaces the lock pin.

摘要： The present invention provides a variable valve mechanism, which includes a rocker arm including an input member and an output member; a switching device that switches a drive state of the valve by displacing the switching pin between a coupling position at which the switching pin extends between the first pin hole in the input member and the second pin hole in the output member and a non-coupling position at which the switching pin does not extend; and a lost motion spring. A displacement clearance is formed between an inner peripheral surface of the first or second pin hole and an outer peripheral surface of the switching pin to permit the relative displacement in a range of the displacement clearance at a coupled time so that a tappet clearance is not formed with the input member urged toward the cam by the lost motion spring.
