Abstract:
1. A compressor arrangement, comprising: a compressor housing; an intake region defined in the compressor housing; a control pressure connection in communication with the intake region; a control pressure chamber in communication with the control pressure connection; a control piston disposed in the compressor housing beneath the control pressure chamber; a guide element securing the control piston in the compressor housing; at least one sealing element disposed between the control piston and the guide element; a feed pressure connection defined in the compressor housing to supply compressed air beneath the control piston; wherein the control piston is disposed in a closed position when the compressor arrangement is in operation and an opened position when the compressor arrangement is in a switched off state, wherein the control piston closes the feed pressure connection when in the closed position due to a greater pressure in the feed pressure connection than in the control pressure chamber, wherein the control piston opens the feed pressure connection when in the opened position due to a greater pressure in the control pressure chamber than in the feed pressure connection, thereby permitting air to vent from the feed pressure connection via a venting connection.
