    摘要: A valve operating system in an internal combustion engine which provides a stable seating force for an engine valve (V) and includes an armature (12) operatively connected to a stem (8) of the engine valve that is capable of being seated on a valve seat member (6) provided to a cylinder head, valve-opening (13) and valve-closing (14) electromagnets for exhibiting electromagnetic forces for attracting the armature to open and close the engine valve, respectively, and valve-opening (15) and valve-closing (16) resilient means for exhibiting resilient forces for biasing the engine valve in opening and closing directions, respectively, and for retaining the armature in a predetermined neutral position by cooperation with each other during deenergization of both the valve-opening and valve-closing electromagnets. When the engine valve is closed by energizing the valve-closing electromagnet and is seated on the valve seat member, only the resilient force of the valve-closing resilient means is applied to the engine valve V because the valve-closing electromagnet attracts the armature and compresses the valve-opening resilient means.

    摘要: A valve operating system in an internal combustion engine including rollers (31,32,33) which are in rolling contact with valve operating cams (23,24) and rotatably supported by support shafts (34,35,36) fixed to rocker arms in a manner such that the support shafts can be easily fixed to the rocker arms. In one embodiment, a rocker arm (25 1 ) is provided with a fitting bore (37) in which a support shaft (34 1 ) is fitted and with a press-fit bore (40) leading to an inner surface of the fitting bore (37). A locking groove (43) is provided in an outer surface of the support shaft (34 1 ) in correspondence to an opening of the press-fit bore (40) into the inner surface of the fitting bore (37), and extends in a direction tangent to a phantom circle (C 1 ) about an axis of the support shaft (34 1 ). A pin (46) is press-fitted into the press-fit bore (40) and engaged in the locking groove (43).
