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.

1. An air regulator for compressors, comprising: an oil separator apparatus,a regulator housing,a valve element in said regulator housing, the valve element being spring-loaded on one side,a piston arrangement connected to a control line for actuating the valve element,pilot control apparatus with a pre-separation pressure port for connection to a source of pre-separation pressure, a valve magnet that is located between the control line and a control piston, the control piston being located between the pre-separation pressure port and said magnet, andwherein the control piston, depending on a pre-separator pressure resulting from starting of a compressor to which the regulator is connected in use, in interaction with the pilot control apparatus actuates the valve element such that, when a compressor to which the regulator is connected is started, the regulator is immediately forced to assume a closed position, while in a base state the regulator assumes an open position. 2. The air regulator as claimed in claim 1, wherein the air regulator is adapted for being triggered in at least one of a pneumatic and electrical manner. 3. The air regulator as claimed in claim 1, wherein the air regulator is adapted for being triggered pneumatically, and the control apparatus contains a check valve between control medium and pre-separator medium areas. 4. The air regulator as claimed in claim 1, wherein the control apparatus is fastened directly on the regulator housing. 5. The air regulator as claimed in claim 1, wherein the control apparatus is in communication with the piston arrangement for loading of the valve element. 6. The air regulator as claimed in claim 1, wherein a diversion apparatus is integrated into the regulator housing. 7. The air regulator as claimed in claim 6, wherein the diversion apparatus comprises a diversion nozzle which in the regulator housing and which discharges directly via a bore into an intake space. 8. A regulated compressor arrangement, comprising: a compressor, andan air regulator connected to said compressor,wherein the air regulator comprises:an oil separator apparatus,a regulator housing,a valve element in said regulator housing, the valve element being spring-loaded on one side,a piston arrangement connected to a control line for actuating the valve element,pilot control apparatus with a pre-separation pressure port for connection to a source of pre-separation pressure, a valve magnet that is located between the control line and a control piston, the control piston being located between the pre-separation pressure port and said magnet, andwherein the control piston, depending on a pre-separator pressure resulting from starting of the compressor to which the regulator is connected, in interaction with the pilot control apparatus actuates the valve element such that, when the compressor to which the regulator is connected is started, the regulator is immediately forced to assume a closed position, while in a base state the regulator assumes an open position. 9. The air regulator as claimed in claim 8, wherein the air regulator is integrated in a compressor housing of the compressor. 10. The air regulator as claimed in claim 8, wherein the compressor is a screw compressor.
