Title:
CONTROL DEVICE FOR PRESSURE-RESPONSE OPERATION TYPE ACTUATOR
Document Type and Number:
Japanese Patent JP3529973
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a control device for a pressure-response operation type actuator to realize high speed responsiveness without damaging durability of an object to be driven.
SOLUTION: A control device for a pressure-response operation type actuator is provided with a pressure chamber 5a to which a variable pressure is fed and a moving partition wall 5b displaced in response to a pressure in the pressure chamber, and drives an object 5A to be driven through displacement of the moving partition wall 5b. The control device comprises various sensors 14 to detect the control state of the object to be driven; a pressure source 9 to feed a variable pressure to the pressure chamber 5a; a first opening closing means 7 to regulate a feed time of a variable pressure; a second opening closing means 18 to regulate the variable pressure into an atmospheric pressure; and an ECU 13A to control opening of the first and second opening closing means 7 and 18 in response to the displacement position of the moving partition wall 5b and the control state of the object to be driven.
