Abstract

PURPOSE:To aim at enhancing the durability and operational reliability of a pressure control valve by transmitting the sound pressure of a sound wave generated by a piezo-electric element so as to vibrate a diaphragm. CONSTITUTION:A piezo-electric element 28 vibrates in accordance with input and feed-back signals to a controller 32 so as to generate sound pressure which is amplified by a resonating chamber 26a so as to vertically vibrate a diaphragm 29 and a plunger 33. Due to vibration of a plunger 23 a nozzle 24 is opened and closed, causing the fluid pressure of a fluid chamber 21 to vary so as to move a diaphragm 17, resulting in opening and closing of a main valve 14. With this arrangement there is no mechanical coupling between the piezo-electric element and the diaphragm 29 so as to eliminate deformation of the piezo-electric element, thereby it is possible to surely prevent the piezo-electric element from being damaged.
