GAS CONTROLLER
Document Type and Number:
Japanese Patent JPS58142088
Kind Code:
A
Abstract:
PURPOSE:To secure such a controller that has no unstable motion, by installing a click body and a ball operating this click body for clicking as well as a spring body, while opening a gas passage only after the click body is kept in a state of being clicked with certainty. CONSTITUTION:When an operating knob 7 is rotated around a rotary center shaft 11 of a click body 6 upon operation in an arrow direction, the click body 6 is set in click motion by means of a ball 18 being pressed by a pressing spring 9 and simultaneously secured forcibly to the position of each stage with the balance between forces of the ball 8, the pressing spring 9 and the click body 6. In this case, since distance D is provided between the terminal of a contactor 5 and a gas on-off valve 10, at a time when the ball 8 exists on the crest of a curved part 6a of the click body 6, the contactor 5 does never push the gas on- off valve 10 so that no gas may come out.
