摘要： The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is swingably supported by a single pivot, and a switching device that operates the rocker arm to switch a drive state of the valve, in which the rocker arm is configured such that at least in a predetermined drive state, a pressing force of the cam is applied disproportionately to one side of the rocker arm in a width direction with respect to a center line when the cam presses a portion of the rocker arm located away from the center line in the width direction. The variable valve mechanism further includes a swing guide that abuts against the rocker arm so that the rocker arm is guided in a swing direction so as not to be tilted in the width direction.

摘要： The present invention provides a variable valve mechanism of an internal combustion engine, which includes an input member, an output member, a slider and a variable device. The output member has internal space formed therein and has a first cutout and a second cutout which are formed at two positions separated from each other in the swing direction so as to extend from an outer periphery of the output member to the internal space, and the input member is mounted in the internal space so as to extend through both inner sides of the first and second cutouts, and is brought into contact with inner side surfaces of the cutouts from both sides in the thrust direction, whereby relative displacement of the input member together with the slider in the thrust direction with respect to the output member is restricted at two positions by the first and second cutouts.

摘要： A variable valve mechanism of an internal combustion engine includes a plurality of swing members and a variable device that displaces a control shaft to displace a plurality of slider gears of the swing members at a time, thereby changing valve lifts of the plurality of swing members at a time by meshing of helical splines. The swing members include a first swing member for a predetermined cylinder of a plurality of cylinders and a second swing member for a cylinder other than the predetermined cylinder, and a helix angle of the helical splines varies between the first and the second swing members. The variable device displaces the control shaft to a predetermined normal position to perform a normal operation, and displaces the control shaft to a predetermined cylinder cutoff position to perform a cylinder cutoff operation in which the second swing member does not drive a valve.

摘要： A variable valve mechanism includes a rocker arm including a first input arm, a second input arm, and an output arm, and a switch device that switches an operating state to a first state by coupling only the first input arm to the output arm, and switches the operating state to a second state by coupling only the second input arm to the output arm. The switch device includes two pins that are displaceably placed in the rocker arm and contact each other at their end faces, and a displacement device that switches the operating state to the first state by displacing a contact portion between the two pins to between the output arm and the second input arm, and switches the operating state to the second state by displacing the contact portion between the two pins to between the output arm and the first input arm.

摘要： A variable valve mechanism includes an input arm that axially supports a roller pressed by a cam, via a roller pin, an output arm that drives a valve when swinging, a switch device that switches the variable valve mechanism between a coupled state where the both arms are coupled and an uncoupled state where the arms are uncoupled from each other, and a lost motion spring that biases the roller against the cam when in the uncoupled state. The lost motion spring includes an extended portion extending in an inter-arm clearance between the input arm and the output arm. An end of the roller pin projects from the input arm into the inter-arm clearance by such a length that the end is accommodated in the inter-arm clearance and that allows a spring retaining portion to be formed in the end. The spring retaining portion is formed in the end.

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 pinhole 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.
