  • Patent number: 7178554
    Abstract: An ultrasonically operated valve a source of ultrasonic energy for excitation of a pressurized liquid. The vibration of the ultrasonic horn imparts a pulsing of the pressure of the liquid within the valve. Selection of a sealing mechanism that responds at a different natural frequency than that of the valve body causes the sealing mechanism to unseat and therefore to enable liquid flow. The sealing mechanism will stay unseated as long as the source is imparting energy to the system and therefore inducing pressure pulses in the liquid thus keeping the sealing mechanism away from the valve seat.

  • Patent number: 6971301
    Abstract: An asymmetrical vibrator is provided, which is actuated by compressed air. The vibrator operates in a case, which has two bores disposed parallel on opposite sides of the casing. One of the bores is smaller than the second bore and the piston operating in the small bore is called the slow piston, since it is actuated with air to a relatively slow motion and the piston operating in the second larger bore is called the fast piston, since it is moves at a larger speed when driven directly by the compressed air. The asymmetric vibration motion can be employed to transport materials upwardly in factories and assembly stations. The air operated asymmetric vibrators need low maintenance and do not entail the spark dangers caused by the presence of electrical wiring for electrical drive motors.

  • Patent number: 5290008
    Abstract: This invention is directed to a discharge controlling device for faucet, characterized in that a control lever is used to push a throttle pin axially positioned within the center of the housing, such that the pin is slidably moved up and down and engages a steel ball which is designed to control the opening and closing of a water discharge aperture. As the control lever is pushed by hand and moved from its lowest closed position to the intermediate, open position where the water can be admitted, the steel ball is pushed away from the aperture by the rod tip of the throttle pin which rises axially. At this instant, water enters through the aperture and flows out of the housing. When the hand is released from the control lever, the throttle pin will fall, and the steel ball, which is subject to water pressure, will immediately return to the position where it closes the aperture.

  • Patent number: 5265842
    Abstract: An engine emission control metering valve includes a metering ball valve element operatively connected to an electrically-energized linear actuator that includes a stationary magnet and a moving coil concentric with the magnet. The coil has a different axial length than the magnet such that application of a current to the coil causes coil-generated magnetic flux to axially push the coil away from the magnet. Coil movement translates into movement of the metering valve element through the wedging action of a cam element driven by the coil movement.
