发明名称 VALVE-ACTUATING DEVICE FOR INTERNAL COMBUSTION ENGINE
摘要 In a valve-actuating device, a rocker arm (18A) has a valve contact portion (15) in contact with an engine valve (6) and a cam contact portion (17) in contact with a valve-actuating cam (16). One end portion of each of a set of link arms (19A, 20A) is supported by an engine main body (1) so as to be swingable about an axis parallel to the rotation axis of the valve- activati ng cam (16). The other end portions of the set of the link arms (19A, 20A) are directly connected to the rocker arm (18A) so as to be relatively swingable about axes parallel to the rotation axis line. At least either one of the on e end portion of each of both link arms (19a, 20A) is swingably supported by t he engine main body (1) so as to be steplessly movable in a plane perpendicular to the rotation axis of the valve-actuating cam (16). This structure enables to make the valve-actuating device compact and to steplessly vary the amount of valve opening lift of the engine valve with excellent follow-up capabilit y of the engine valve to the valve-actuating cam maintained.
