<p>An air regulator for compressor, in particular for a screw compressor, of the type that has an oil separator device comprising a pre-separator, is provided in a regulator housing containing a valve element which is spring-loaded on one side and can be actuated by means of a piston arrangement. A control device is operatively connected to the air regulator and includes a control piston which, depending on the pre-separator pressure, actuates the valve element of the air regulator in co-operation with a pre-control device in such a way that the regulator immediately and forcibly assumes the closed position upon starting the compressor, while the regulator assumes the open position in an unloaded initial state.</p> |
