Title:
PNEUMATIC TYPE LIGHT CONTROLLED POSITIONER
Document Type and Number:
Japanese Patent JPS6283502
Kind Code:
A
Abstract:
PURPOSE:To make an electric power supply wiring for a light controlled positioner unnecessary, by rotating a fan connected to a generator motor with an air pressure which is supplied from an air supply pipe, and utilizing the electric power from the generator motor as the electric power supply of the light controlled positioner. CONSTITUTION:A light controlled positioner which controls an operational valve 9 is supplied with pressure air as the driving power source of the operational valve 9. And the supply pipe 84 of the pressure air is connected with a manifold 84a, furthermore a fan 86 which is rotated by air stream and connected with a generator motor 87 is disposed on the opening end of the manifold 84a. Therefore, the light controlled positioner has a self generating function, and even if it utilizes a microprocessor 102 for controlling and the like as auxiliaries, the wiring of an outer electric power source becomes unnecessary.
