Abstract

PURPOSE: To provide both a smoke exhausting function and a fire preventing function, by installing in a cylinder the second piston thrusted by a spring, and by installing in the rod of the second piston the first piston thrusted by a spring, and by placing a supply and discharge pipe in the cylinder.
CONSTITUTION: The second piston 4 thrusted by a spring 6 is fitted in a cylinder 1. The first piston 14 thrusted by a spring 16 is fitted in the second piston rod 5. A supply and discharge pipe 18, which communicates with the first cylinder chamber 17, is protruded from the rear lid 3 of the cylinder 1. When compressed air is discharged out of the first cylinder chamber 17, the first piston rod 15 is moved back to open a smoke exhaust duct. When compressed air is discharged out of the first cylinder chamber 17 and the second cylinder chamber 7, the first piston rod 15 is moved forth to close the smoke exhaust duct. A smoke exhausting function and a fire preventing function are thus provided.
