Piston Compressor with a Closing Device for the Outlet Line

A piston compressor for compressing a gas, comprising:

• an inlet valve, which is arranged between an inlet line for gas for compression and a compression chamber of the piston compressor;
• an outlet valve, which is arranged between the compression chamber of the piston compressor and an outlet line for compressed gas;
• a separate closing device, which is arranged downstream of the outlet valve in a flow direction of the gas by which the outlet line is closable with respect to the compression chamber;
• a clutch by which the piston compressor is separable from a drive device;
• and
• a control device which has a signal connection both to the clutch and to the separate closing device;
• wherein
• a switchable valve device forms the closing device, and
• the control device is configured to switch the switchable valve device into a closed position when the clutch between the piston compressor and the drive device is open.
