Abstract

PURPOSE: To enable to use a small bored electromagnetic valve by connecting a pressure tank to a supply tank only when a piston in a cylinder valve is moved to a reverse side of a pressure chamber and communicating the supply tank with open air only when the piston is moved to a side of the pressure chamber.
CONSTITUTION: A supply tank 25 is provided beside a pressure tank 15 at a position lower than the lower-limit level for the pressure tank 15. The upper portion of the supply tank 25 is connected to open air through a valve 26 allowing sucking only, also, to the pressure tank 15 through a non-return valve 27 allowing discharging only. The bottom portion of the pressure tank 15 is connected to a pressure chamber 36 facing to an end of a piston 35 in a cylinder valve 34 through an electromagnetic valve 21, and the chamber 36 is connected to open air through a choke of small hole 37 respectively. The piston 35 is energized toward the pressure chamber side, and only when the piston 35 in the cylinder valve 34 is moved to the reverse side overse side of the pressure chamber, both tanks 15, 25 are communicated, while only when the piston 35 is moved to the pressure chamber side, the tank 25 is connected to open air. By avobe-described valve machanism, the operation of the electromagnetic valve 21 is controlled.
