ABSTRACT:
Disclosed is a gas cycle apparatus for a tire vulcanizer, configured to increase the circulating flow rate of a heating gas by preventing a gas feeder of the gas cycle apparatus from being subjected to an excessive load caused by a drain, and thereby capable of shortening the tire vulcanizing time by improving the temperature difference eliminating capacity in a bladder, to thereby allow the enhancement of the production capacity of tires. A gas circulating flow path2constituted by allowing a forward flow path2aand a return flow path2bto communicate with each other, is connected to a bladder1;a gas supply flow path3is connected to the forward flow path; an air-water separation section5is provided on the way through the return flow path; the return flow path is connected to an upper space5aof the air-water separation section; and a gas discharge flow path4is connected to a lower space5bof the air-water separation section.
