Patent attributes
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 path 2 constituted by allowing a forward flow path 2a and a return flow path 2b to communicate with each other, is connected to a bladder 1; a gas supply flow path 3 is connected to the forward flow path; an air-water separation section 5 is provided on the way through the return flow path; the return flow path is connected to an upper space 5a of the air-water separation section; and a gas discharge flow path 4 is connected to a lower space 5b of the air-water separation section.
