Device to drain away liquids from a separating container submitted to compressed air

摘要

Liquids are sepd. from compressed air in a sepn. vessel having a valve (2) at its lowest point with valve seat (4) and closing member (4) which can be brought into sealing contact. The closing member is supported by a valve spring (5) and is acted on by the pressure of the compressed air to force it on the seat. The spring lifts the closing member from the seat when the compressed air pressure falls below an arbitrary min. value. Closing member is pref. of an elastomeric material and the valve spring is pref. a coil spring.
