摘要： A valve moving apparatus of an internal combustion engine comprises an engine valve, a valve spring, a spring seat supporting an end of the valve spring and a cam driving the engine valve to open. A valve spring set load changing device in the valve moving apparatus comprises the spring seat including a base seat and a support seat movable relatively to the base seat, an actuator generating drive force in accordance with an operational condition of the engine and a manipulating mechanism transmitting the drive force to the support seat. The actuator and the manipulating mechanism are positioned outside of the spring seat. When the support seat is rotated by a predetermined amount by the drive force transmitted through the manipulating mechanism, the support seat moves also in direction of expansion and contraction of the valve spring to change set load of the valve spring.

摘要： It is proposed to lessen the weight and improve the mechanical strength of a retainer of a valve open-close mechanism driven by an electromagnetic actuator used in an automotive internal combustion engine. The electromagnetic actuator is mounted in a housing mounted on an internal combustion engine body. A first stem has its tip abutting the valve, which is provided with a retainer and carries a first coil spring. A second stem is provided on the other side of an armature. The second stem has a retainer. Between this retainer and the housing, a second coil spring is mounted. At least one of these parts is made of a metal smaller in specific weight than iron or its alloy. Each retainer has a boss and an arcuate corner portion having a radius of curvature R of 1.0 mm or over between a spring abutting surface and the boss to relieve stress concentration.

摘要： A valve-operating mechanism includes cam followers carried on an engine body 1 with their tip ends being in sliding contact with the cam, rocker arms integrally connected to the cam followers and carried on the engine body coaxially with said cam followers with their tip ends being connected to valves, and valve springs for biasing the valves in closing directions. In the valve-operating mechanism, auxiliary springs are connected to the cam followers for biasing and turning the cam followers in the same directions as directions in which the valve springs bias and turn the rocker arms through the valves. Thus, a couple of forces generated over the axis of the cam follower and the rocker arm due to biasing force of the valve spring can be offset in a valve-closing process.

摘要： A valve spring retainer is mounted to the upper end of a poppet valve via a pair of cotters in an internal combustion engine of an automobile. The valve spring retainer has an intermediate portion and an outer flange which is engaged with the upper end of a valve spring. The lower surface has a gap between the outer flange and the intermediate portion to decrease wear which is caused by engagement with the valve spring. There is also provided a valve operating mechanism which has a valve spring retainer which has a projection on the lower surface so as to prevent wear.

摘要： In a valve train of an internal combustion engine having a switchable support element (1), the lost motion spring (18) of the support element (1) is arranged axially offset next to the support element (1) while being coupled to an inner element (3) of the support element (1) by a crossbar (20). Due to this externally positioned spring (18), the support element (1) requires only a relatively small design space.
