    摘要： Provided is a variable valve device for an internal combustion engine. The variable valve device includes intake- and exhaust-side swing arms that pivot to open and close intake valves and exhaust valves in two cylinders #1, #2, intake- and exhaust-side hydraulic lash adjusters that serve as pivot points of the respective swing arms, a variable valve system that continuously varies valve lift characteristics of the intake valves and lost motion mechanisms that stop opening and closing of the intake exhaust valves by lost motion of the intake- and exhaust-side hydraulic lash adjusters on the cylinder #1. The maximum valve lifts of the intake valves are set larger than valve lifts of the exhaust valves. The minimum valve lifts of the intake valves are set smaller than the valve lifts of the exhaust valves.

    摘要： A driver that reciprocates has its reciprocation divided into a non-actuating portion and an actuating portion. The driver in one embodiment positions a carrier that has two pins, each pin being slidably mounted in its slot on a housing. One of the pins is an output pin that may be linked to operatively position a valve of an internal combustion engine. The two slots are configured such that each pin, during its motion range, does effect a capture of the other pin such that the captured pin is generally stationary. When the output pin is captured, the driver reciprocation causes the non-output pin to perform a lost-motion traverse of its slot. When the non-output pin is captured, the driver reciprocation actuates the output pin. A linked pair of such embodiments driven by a single driver can thus alternately actuate two valves.

    摘要： An internal combustion engine includes a driving shaft, a pair of camshafts for driving engine valves, a transmission connecting the driving shaft to a first of said camshafts and a transmission connecting the first camshaft to the second camshaft. The transmission connecting the two camshafts to each other includes a pair of articulated parallelogram mechanisms each having two crank members rotatable with end portions of the camshafts and connected to each by means of a connecting rod. The crank members are made up of circular discs eccentrically mounted on the camshafts and rotatably received in circular openings formed at the ends of the respective connecting rod. The two crank members rotatable with the same camshaft are spaced from each other by a determined angle.

A rockable cam is supported on the first camshaft so that the rockable cam rotates or oscillates about the axis of the first camshaft. A rocker arm is oscillatingly supported on an outer periphery of the eccentric cam so that a center of an oscillating motion of the rocker arm revolves around the axis of the first camshaft. Also provided is a control shaft variably controlling the center of the oscillating motion of the rocker arm.
