Title:
PNEUMATIC REMOTE CONTROL SYSTEM
Document Type and Number:
Japanese Patent JPH02293230
Kind Code:
A
Abstract:

PURPOSE: To easily obtain fluid which drives actuators by closing the exhaust valve of the one actuator at higher pressure in response to a difference between pneumatic pressures in the actuators, and opening the exhaust valve of the other actuator.

CONSTITUTION: When a spherical part 24 is manually constricted, increased pressure closes flap valves 30, 31 and opens a flap valve 34 to allow air into an actuator chamber 14. Then the increase in pressure causes closing of an exhaust valve 62, and a rod 60 opens an exhaust valve 64 in the other actuator chamber 16 to communicate with the atmosphere via an outlet 58. When the spherical part 24 is loosened, the flap valve 34 closes and the flap valves 30, 31 open to draw a large amount or air into the spherical part 24. Then the expansion of a film 18 caused by an increase in pneumatic pressure within the chamber 14 causes the movement of a projecting part 22 to tilt mirror support 10. When the spherical part 44 is constricted, air enters the other actuator chamber 16, tilting the mirror support 10 in the opposite direction.
