摘要： A variable valve mechanism includes a first cam and a second cam, a main arm that drives a valve when swinging, a first sub arm that swings when pressed by the first cam, a second sub arm that swings when pressed by the second cam, and a switch device. The switch device includes a first switch pin that moves between a first coupled position between the main arm and the first sub arm and a first uncoupled position, and a second switch pin that moves between a second coupled position between the main arm and the second sub arm and a second uncoupled position. Both switch pins are arranged so as to be displaced from each other in positions where these switch pins do not overlap at least during a base circle phase in which base circles of both cams act.

摘要： The present invention provides a variable valve mechanism of an internal combustion engine, which includes a rocker arm that is driven by a cam so as to swing to drive a valve, a switching pin that is attached to the rocker arm so as to be shifted between a first position and a second position, a shift device that shifts the switching pin from the first position to the second position, and a return spring that returns the switching pin. In the variable valve mechanism, a drive state of the valve is switched by shifting the switching pin, the rocker arm is formed to have such a dimension that one end of the switching pin is exposed while projecting outward from the rocker arm, and the return spring is externally fitted to the one end of the switching pin so as to be exposed outside the rocker arm.

摘要： An auxiliary valve actuating mechanism of an engine is provided. The engine includes a conventional valve actuating mechanism (200) and an auxiliary valve actuating mechanism (2002). The auxiliary valve actuating mechanism (2002) includes an auxiliary cam (2302), an auxiliary rocker-arm shaft (2052), an auxiliary rocker arm (2102), an eccentric rocker-arm shaft bush (188) and a shaft bush actuating mechanism (100). The eccentric rocker-arm shaft bush (188) is provided inside the shaft hole of the auxiliary rocker arm (2102). The auxiliary rocker-arm shaft (2052) is provided inside the eccentric rocker-arm shaft bush (188). The shaft center of the auxiliary rocker-arm shaft (2052) is biased from the shaft center of the eccentric rocker-arm shaft bush (188). One end of the auxiliary rocker arm (2102) constitutes a motion pair with an auxiliary cam (2302), and the other end is above the valve (300). The shaft bush actuating mechanism (100) actuates the eccentric rocker-arm shaft bush (188) to rotate between an operating position and a non-operating position. At the non-operating position, the rocking center line of the auxiliary rocker arm (2102) is away from the valve (300), and the auxiliary rocker arm (2102) is separated from the valve; and at the operating position, the rocking center line of the auxiliary rocker arm (2102) is close to the valve, the auxiliary rocker arm contacts with the valve, and the movement of the auxiliary cam is transmitted to the valve to generate the motion of the auxiliary valve. The auxiliary valve actuating mechanism is simple in structure, and easy to mount.

摘要： A valve train assembly comprises: a rocker arm (2) comprising: a first body (10) supporting a first axle (24) on which a first roller (22a, 22b) for engaging a first rotatable cam surface (34, 36) is mounted, whereby at least part of the rocker arm (2) can be pivoted by at least the first rotatable cam surface (34, 36) acting on the first roller (22a, 22b) to move a valve (4) to cause a first valve even. The rocker arm (2) further comprises a second body (8) supporting a second axle (43) on which a further roller (26) for engaging a further rotatable cam surface (38) is mounted, whereby at least part of the rocker arm (10) can be pivoted by the further rotatable cam surface (38) to move the valve (4) to cause a second valve event. One of the first (10) and second (8) bodies is pivotally mounted with respect to the other of the first (10) and second (8) bodies. The rocker arm (2) is configurable in a first mode of operation in which one of the first and second valve events occurs and a second mode of operation in which both the first and second valve events occur or the other of the first and second valve events occurs. The rocker arm (2) further comprises a latching mechanism (40) for latching and unlatching the first (10) and second (8) bodies together and wherein which of the first and second modes the rocker arm (2) is configured in depends upon whether the first (10) and second (8) bodies are latched or are unlatched. The latching mechanism (40) comprises a latch member (80) moveable between a latched position wherein it latches the first (10) and second (8) bodies together and an unlatched position in which the first (10) and second (8) bodies are unlatched The valve train assembly further comprises a latching actuator (94) for moving the latch member (80) between the latched position and the unlatched position and wherein the latching actuator (94) comprises a rotatable shaft (96) attached to a biasing means (98), wherein rotating the rotatable shaft (96) from a first position to a second position causes the biasing means (98) to move the latch member (80) between the latched position and the unlatched position.
