Title:
COMPRESSED AIR DISCHARGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/145573
Kind Code:
A1
Abstract:
A compressed air discharge device 10 has a primary valve 12 and a secondary valve 13. The primary valve 12 is switched between a discharge position M2 at which compressed air is discharged to a discharge port B, and a blocking position M1 at which the discharge is blocked. The secondary valve 13 is switched between an air supply position P2 at which compressed air is supplied to a pilot chamber 37 through a supply/discharge flow passage 71, thereby switching the primary valve 12 to the discharge position M2, and an air discharge position P1 at which compressed air within the pilot chamber 37 is discharged to the outside. Compressed air is intermittently discharged from a discharge opening when the secondary valve 13 is switched between the air supply position and the air discharge position.
