ABSTRACT:
An apparatus and method are disclosed for the simple removal of liquid condensate, in particular of water of condensation, from compressed-air systems alternately subjected in operation to positive pressure and atmospheric pressure. The compressed-air system is first of all connected for a limited period, at intervals or after each subjection to positive pressure, to a vacuum generator in order to promote re-evaporation of the condensate and is evacuated by the latter before atmospheric pressure is passed in or let in again. In certain embodiments, a highly restricted reverse flow through the compressed-air system is permitted. The method is particularly suitable for use in small-volume compressed-air systems which do not have to be permanently subjected to positive pressure, e.g., in pneumatic door-closing aids for motor cars.
