Abstract
PURPOSE: To prevent a drain from being accumulated in the discharge pipe by a method wherein one end of the discharge conduit for the enclosed fluid is extended upward with an upward slope in a rubber dam which is raised or lowered in response to a feeding and discharging of the fluid such as air etc.
CONSTITUTION: Air suctioned from the air inlet port 17 is forcedly fed into the rubber dam 4 from the inlet port 14 via valves b5, b2, b1 and the conduit 12 to raise the rubber dam 4. Air enclosed in the rubber dam 4 is discharged from the discharge port 16 from the feeding port via conduit 12 and the valves b1, b4, b3 to lower the rubber dam 4. Conduit 12 is applied for an air feeding conduit and a discharge conduit.
