    摘要: A valve operating system in an internal combustion engine is disclosed, wherein the operational characteristic of an engine valve which is an intake valve or an exhaust valve, can be changed in accordance with the operational state of the engine. In the valve operating system, a power transmitting means comprises an inner wheel, an outer wheel surrounding the inner wheel, and a carrier on which a planetary rotor is rotatably carried. The inner wheel is operatively connected to a cam shaft, and the outer wheel is connected to the engine valve. A rotational-amount control device is connected to the carrier for controlling the rotational amount of the carrier in accordance with the operational state of the engine. Thus, the size of the valve operating system can be reduced, and moreover, the operational characteristics of the engine valve can be finely changed.

    摘要: A valve operating system includes a connection switch-over device provided in a plurality of cam followers. The connection switch-over device has a piston moved in response to a change in hydraulic pressure in a hydraulic pressure chamber. A roller shaft is disposed on at least one of the cam followers and has a roller carried thereon to come into rolling contact with a valve operating cam. In this valve operating system, the hydraulic pressure chamber and a communication passage, which permits an oil supply passage to communicate with the hydraulic pressure chamber, are defined in a particular one of all the cam followers, which moves a smallest amount when the connection switch-over device is in its disconnecting state. The roller shaft, having the roller rotatably carried thereon, is mounted on the cam follower other than the particular one cam follower. Thus, it is possible to avoid an increase in size of the particular one cam follower, and avoid a complicated assembling operation and passage construction. Moreover, the valve operating load is reduced to a minimum by using the roller.

    摘要: A variable stroke characteristic engine is provided in which a piston (11) and a crankshaft (30) are linked to a control shaft (65) via a variable stroke link mechanism (LV), and the variable stroke link mechanism (LV) is operated by an actuator (AC) that drives the control shaft (65) to thus make the stroke travel of the piston (11) variable, wherein a housing (HU) of the hydraulic actuator (AC) for operating the variable stroke link mechanism (LV) is provided in a bearing member (54) of a lower block (41) supporting the crankshaft (30), and the housing (HU) is thus made small, thereby suppressing any increase in the dimensions of the engine. Furthermore, a hydraulic switching valve unit (92) for controlling operation of the hydraulic actuator (AC) is directly mounted on the housing (HU), thereby enhancing the responsiveness of the hydraulic actuator (AC).
