    摘要: A cylindrical support portion is provided on a wafer pump case to surround a rotary shaft, and a cylindrically formed power transmitting rotary wheel surrounding the support portion is integrally coupled to an outer end of the rotary shaft which protrudes outwardly from the support portion. A bearing means is interposed between an inner surface of the power transmitting rotary wheel and an outer surface of the support portion. A plurality of sealing members disposed concentrically with the bearing means are interposed between the rotary shaft and an inner surface of the cylindrical support portion at a location axially outwardly spaced from the mechanical seal, and a grease is filled between the sealing members. The water pump structure not only improves the sealing property of the sealing members by providing the sealing members at a location in which the deflection of the rotary shaft is smallest, but also increases the retaining property for the grease between the plurality of sealing members. This enhances water resistance of the bearing means. Moreover, in spite of the provision of the plurality of sealing members and the bearing means, the water pump structure avoids an undesirable increase in size and remains relatively compact.

    摘要: An intake manifold device for an internal combustion engine that has an engine body with an intake port connected to an intake valve port which is openable and closable by an intake valve operatively coupled to a valve operating mechanism capable of varying the intake valve operation between low and high speed operation. The intake port is connected to an intake chamber through a first intake passageway which has a length and a cross-sectional area for a low-speed range and through a selectively openable and closable second intake passageway which is openable in a high-speed range. Independently characterized in openable and closable on/off valve are disposed respectively in upstream and downstream ends of the second intake passageways. The on/off valves and intake valves operating mechanism are selectively operated for maximizing the torque output of the engine over a wide range of speeds.

    摘要: An internal combustion engine intake device having a high-speed intake passage for high-speed operation and a low-speed intake passage for a low-speed operation of the engine. Each high- and low-speed intake passage is connected to an intake port and valve hole of each cylinder of the engine. An intake box is connected to the upstream ends of the high- and low-speed intake passages and has in inlet coupled to a throttle body having a throttle valve operable in response to throttle operation by the driver. Control valves are disposed in each high- and low-speed intake passage for individually controlling the flow passage areas and the valves are operated to provide the optimum intake air flow.
