Abstract
The invention provides an automatic drain device with membrane for pneumatic circuits. A flexible membrane (11) which separates the opening (2) of a jar (1) from a drain pipe (6) is precurved in a top position against this opening and against a skull-cap (8) against which it bears, which skull-cap then closes a communication orifice (14) provided on one side of the membrane. Under the action of the pressure in the jar, the membrane moves down to come to bear against a discharge end-piece (5) freeing, during this movement, orifice (14) and making drainage possible.
