摘要： A rocker arm includes a first end including a substantially horizontal wall having a receptacle formed therein. A second end of the rocker arm is spaced from the first end and includes a substantially horizontal wall for engaging a valve stem. A pair of spaced substantially parallel vertical sidewalls extend between the first end and the second end. In one embodiment, the sidewalls define a width between the first end and the second end that is less than each of the widths of the first and second ends. In another embodiment, a transverse wall extending between the sidewalls is formed in the second end. In yet another embodiment, rocker arm alignment walls are formed in the second end independently of the sidewalls.

摘要： A drive cam opens or closes an intake valve via a variable mechanism, a split-type rocking cam arm, and a valve actuating mechanism. The variable mechanism varies a position of an intermediate roller corresponding to a rotating angle of a control shaft, thereby variably setting a lift amount of the intake valve. The split-type rocking cam arm includes an input arm and an output arm, and a connection selection mechanism is disposed between the arms. When the arms are connected together, the intake valve performs an ordinary open/close operation. When the arms are disconnected, an input of the drive cam is absorbed by a relative rocking motion between the arms, so that the intake valve is retained in a pause state.

摘要： Connecting element (10) retains cam follower (2), which actuates gas-exchange valve (4) of an internal combustion engine, on support element (6). Support element (6) has spherical end (7) on cylindrical section (22) and on which cam follower (2) is mounted, so as to be pivotably movable in the direction of gas-exchange valve (4) about center of rotation (9). Connecting element (10) has elastically deformable projections (21), which proceed from central webs (19), parallel to the pivot axis of cam follower (2) such that connecting element (10) is connected to cylindrical section (22) in a frictionally-engaging manner. Projections (21) are embodied as lugs (20) which angle away from central webs (19) and extend in a direction pointing away from cam follower (2), so that projections (21) are elastic in shape.

摘要： The invention provides an internal combustion engine equipped with a variable valve control system which switches the actions of an engine valve by sliding a rocker arm in the axial direction of the rocker arm shaft, while enabling the restriction on the sliding movement of the rocker arm to be removed in accordance with the timings of the actions of the rocker arms irrespective of the engine speed. The internal combustion engine includes an actuator that moves a rocker arm shaft in its axial direction, a trigger arm that engages with a rocker arm to prohibit the sliding movement of the rocker arm, and a trigger pin which is configured to be activated by an axial movement of the rocker arm shaft to bring the trigger arm into action, and to disengage the trigger arm from the rocker arm.

摘要： A variable valve mechanism for an engine includes: a rocker shaft; a first rocker arm rotatably supported by the rocker shaft, for transmitting displacement of a first cam to a valve; a second rocker arm rotatably supported by the rocker shaft, for transmitting a displacement of a second cam to the valve; and a switching mechanism for switching a transmitting state and a non-transmitting state. The first rocker arm has a pair of first arm portions and a recess portion in which an upper end of the valve is inserted at an end portion of each of the first arm portions. The second rocker arm has a second arm portion disposed between the first arm portions. The first rocker arm is restricted from movement in an axis direction of the rocker shaft when an inner sidewall of the recess portion is in contact with the upper end of the valve. The second rocker arm is restricted from movement in the axis direction when the second arm portion is in contact with the first rocker arm.
