摘要： An electrothermally operated valve which comprises a housing provided thereon with first and second ports and with a hermetic chamber in communication with the respective ports, a bimetallic element having a stationary end secured to an inner wall of the housing and a movable end, a cut-off valve including a valve body fixed on the movable end of the bimetallic element to co-operate with one of the first and second ports, and a heating coil coupled with the bimetallic element and adapted to be connected with a source of electricity. When the bimetallic element is heated upon energization of the heating coil, deflection of the bimetallic element is assisted by snap action to open the cut-off valve so as to communicate the first and second ports to each other through the hermetic chamber.

摘要： A solenoid-operated fluid control valve has an armature assembly which includes a reciprocally movable platelike magnetic valve member and a seal element loosely retained by the valve member and projecting therefrom. A magnetic core defines a fluid passageway and has a valve seating surface at its one end. The valve seating surface of the magnetic core opens in a valve chamber which surrounds the side surface of the magnetic valve member to guide its movement toward and away from the valve seating surface and to maintain the seal element in alignment with the valve seating surface. The seal element has opposed conical or spherical ends and an annular recess therebetween. The seal element loosely engages with and retained by an opening of the magnetic valve member to abut concentric with the valve seating surface of the magnetic core in spite of a slight eccentricity of the assembly within the valve chamber. The solenoid-operated fluid control valve also has a compression spring positioned concentric with the magnetic valve member and bears at one end against the magnetic valve member and a solenoid mounted on a bobbin in which the magnetic core is secured.

摘要： An electrically operated switching valve comprising a valve housing provided with a pair of opposed valve ports, a valve member disposed between the valve ports for co-operation therewith and a snap-action valve actuating device for actuating said valve member alternately into engagement with the valve ports. The valve actuating device includes a rectangular plate which is bent in one direction along the longitudinal center line and a strap member extending between diagonally opposite corners of the plate and secured thereto. The strap member has a length which is smaller than the diagonal dimension of the plate so that the plate is deflected under tension applied by the strap member in the opposite direction along the transverse center line of the plate. The strap member is associated with an electric heating wire so that it is heated when the wire is energized. Since the strap member has a coefficient of thermal expansion which is greater than that of the plate so that it is expanded by a greater extent than the plate when heated by the wire allowing the plate to return with snap action to its undeflected position.

摘要： An electromagnetic control valve is provided with a housing having an inlet and two outlets extending through the wall of the housing. A valve member is mounted in spaced relation from each outlet opening on a resilient member for movement into and out of engagement with a valve seat surrounding the outlet opening. An elongated valve actuator is pivoted at its mid-point between the two valve members and is provided with a projection adjacent each end disposed in contact with a respective valve member. A spring normally biases the valve actuator about its pivot point to bias one of the valve members into engagement with its associated valve seat. An electromagnet is located on the opposite side of the valve actuator from said one of said valve members to pivot the valve actuator against the force of the spring.

摘要： In an electrical speed sensor for generating an electrical signal proportional to the rotational speed of a vehicle wheel, a first shaft is rotatably mounted and is adapted to be operatively interconnected with an output shaft of the vehicle transmission. The first shaft carries a rotor of magnetic material which is cooperable with a stationary rotor of magnetic material to provide an output signal indicative of the rotational speed. A second shaft is rotatably mounted at a fixed angle relative to the first shaft in operative driven engagement therewith. The rotatable core of a speedometer cable is coupled to one end of the second shaft for rotation therewith to operate the vehicle speedometer.

摘要： A constant speed driving device has an ejector for supplying negative pressure to an actuator which controls the engine's throttle valve. The ejector includes a diffuser communicating with the engine intake manifold downstream of the throttle valve and a nozzle communicating through a pressure responsive control valve with the intake conduit upstream of the throttle valve and downstream of the supercharger. A negative pressure suction port of the ejector communicates with the negative pressure inlet port of the actuator. The constant speed control device is capable of supplying, even in the operation of the supercharger, a sufficiently increased negative pressure to the actuator for operating the throttle valve without the need to provide a vacuum pump.Further, the speed control device includes an electro-magnetic valve connected to the engine computer, which valve being is responsive to an input signal from the computer to pressure lock the pressure responsive control valve in its closed position so that the pressure from the supercharger cannot cause an air stream to flow through the nozzle. As a result, no negative pressure is applied to the actuator by the ejector.
