摘要： An idle position detection switch, in which a fixed contact, a terminal for transmitting an idle position signal to an external terminal, and a support disc firmly attaching both the fixed contact and the terminal are insert-molded into a connector made of a resin. As a result of the construction, not only the switch can be fabricated with less components and less cost, but also each contact portion has such an improved rigidity as to allow the incidence of false contacts to be reduced.

摘要： An idle position detecting switch includes a metal housing supported on a throttle body and being electrically connected to the throttle body. the housing contains a push rod which is axially slidable therein, one end of which forms a moveable contact in the housing. A fixed contact is fixed in the housing via a resinous insulator which is connected to a resinous guide for supporting and guiding the push rod. A metal spring in the housing biases the push rod such that the movable contact is spaced from the fixed contact and has opposite ends respectively connected to the movable contact and the housing. As a result, the guide and insulator can independently be incorporated with each other even before a connector is fixed to the housing.

摘要： A return spring assembly for use in an engine intake throttle valve return device comprising a spring holder sleeve (17) including an inner and outer sleeves (18,20) placed over a throttle valve shaft (3) and connected at one end to each other so that the inner and outer sleeves (18,20) are spacedly and concentrically held. Inner and outer torsion coil springs (8,9) are supported on the inner and outer sleeves (18,20), respectively, and connected between an intake barrel (1) and the valve shaft (3) for urging the throttle valve (2) to its closed position. An eccentric radial flange (22) which may be circular, oval or polygonal is provided on the outer sleeve (20) for holding the outer torsion coil spring (9). The eccentric flange (22) extends continuously over the entire circumference of the outer sleeve (20) and has a maximum outer diametrical dimension substantially equal to the inner diameter of the outer torsion coil spring (9). The eccentric flange (22) is eccentric with respect to the outer sleeve (20) by an amount effective to prevent the outer coil spring (9) from being disclocated from the outer sleeve (20).

摘要： An idling position detecting switch for an internal-combustion engine, comprising a conductive tubular housing mounted on a throttle body of a throttle valve for regulating fuel-air mixture supply rate provided on an intake manifold for supplying a mixture to the combustion chamber of an internal-combustion engine, a push rod axially slidably supported in the housing and having one end projecting from one end of the housing so as to be in contact with a stopper connected to a valve shaft of the throttle valve, and the other end disposed within the housing and provided at the extremity thereof with a movable contact, a fixed contact disposed opposite to the movable contact within the housing, and a spring urging the push rod toward the stopper so that the movable contact is separated from the fixed contact and absorbing shocks applied to the push rod by the stopper of the throttle valve. The spring has one end firmly fixed to the push rod at a position near the movable contact and the other end firmly fixed to an inner surface of the housing. A detention mechanism is provided to prevent the turning motion of the spring within the housing due to a turning effect resulting from an axial sliding movement of the push rod.

摘要： A proportional flow control valve in which a valve seat is provided in the proportional flow control valve body, a valve piece is slidably mounted on a movable iron core, and is urged toward the valve seat by an elastic member disposed between the valve piece and the movable iron core, and a holder is fixedly mounted on the movable iron core so as to limit the movement of the valve piece toward the valve seat caused by the elastic member. The proportional flow control valve is high in reliability in which the leakage of fluid is substantially zeroed even when fully closed, and the difficulties are eliminated that, when its flow rate adjusting means engages with or disengages from the valve seat, hammering sounds are produced and the flow characteristic is adversely affected, and which is simple in adjustment and is maintained correct in flow characteristic at all times.
