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.

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.
