FIELD: pneumohydraulic devices.

SUBSTANCE: invention allows you to adjust the level of opening of the water drain from the receiver. The automatic water drain device (1) includes a body (2), a top cover (3) with a pipe (4), a bottom cover (5) with a pipe (6), a float consisting of an upper section (7) and a lower section (8), as well as a valve, which includes a stopcock body (9), a jet fixed in it (10) and a hollow stem (11) with a tip (12) sealed in the lower part.
