  • Patent number: 8057193
    Abstract: A compressor arrangement includes 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, and a feed pressure connection defined in the compressor housing to supply compressed air beneath the control piston. In a closed position, the control piston closes the feed pressure connection when in the closed position. In an opened position, the control piston opens the feed pressure connection when in the opened position, thereby permitting air to vent from the feed pressure connection via a venting connection.
