    摘要： A device for reducing friction while maintaining characteristics identical to the pressure characteristics of a common oil pump based on provision of a plurality of discharge sources and a newly devised method of switching oil passages. The device is configured from a first discharge passage from a first rotor assembly to an engine, a first return passage that returns to an intake side of the first rotor assembly, a second discharge passage from a second rotor assembly to the engine, a second return passage that returns to an intake side of the second rotor assembly, and a pressure control valve whose valve main body is provided between a discharge port from the second rotor assembly and the first discharge passage. The first discharge passage and the second discharge passage are coupled, and a flow passage control is executed in each of: a low revolution range in a state in which only the first discharge passage and the second discharge passage are open; an intermediate revolution range in a state in which the first discharge passage and second discharge passage are open and the first return passage is closed while the second return passage is open; and a high revolution range in a state in which the second discharge passage is closed while the first discharge passage is open and the first return passage and second return passage are open.

    摘要： A throttle valve device for use in an internal combustion engine comprises a valve shaft extending across an air induction passage of the engine. A valve plate is fixed to the valve shaft to rotate therewith in the air induction passage. An electric actuator is connected to one end of the valve shaft to rotate the valve shaft with the aid of electric power. A biasing cam structure is incorporated with the valve shaft to bias the valve place toward a predetermined intermediate open position. The biasing cam structure comprises a cam plate which is secured to the other end of the valve shaft to rotate therewith and has a generally V-shaped cam edge; a loading lever which has a base end pivotally connected to a fixed portion; a follower member which is connected to a leading end of the loading lever and slidably engaged with the V-shaped cam edge; and a biasing member which biases the loading lever in a direction to press the follower member against the V-shaped cam edge.

    摘要： A device for returning a reciprocating mechanism to a predetermined intermediate position of reciprocating motion, comprises a reciprocating link movable in accordance with a predetermined reciprocating motion, a pair of positioning members provided at both sides of the predetermined intermediate position of reciprocating motion, a pair of movable blocks, and a single resilient member interconnecting the movable blocks. The positioning members is adapted to position the movable blocks by abutting the movable blocks against the respective positioning members via a biasing force created by the single resilient member. The movable blocks is adapted to return the reciprocating link to its predetermined intermediate position by abutment of the reciprocating link on both the movable blocks, for restricting a reciprocating motion of the reciprocating link via the biasing force created by the single resilient member. During the reciprocating motion, one of the movable blocks breaks contact with the associated positioning member and additionally the reciprocating link breaks contact with the other positioning member by pushing the associated one of the movable blocks in a direction of increasing the biasing force created by the single resilient member.
