  • a means for maintaining the pressure of a cooling medium in the cooling space above the pressure of a compressor medium in the compressor chamber during operation of the compressor device is provided accordingly.
  • the pressure of the cooling medium is maintained during the operation of the compressor device above the pressure of the compressor or compressor medium. According to the invention, this ensures that even in the case of leaks on a partition between the compressor chamber and the cooling chamber, no gas can escape from the compressor device into the cooling medium.
  • the compressor device according to the invention is in view of the danger situation on the partition wall between the compressor room and the refrigerator is particularly well protected.
  • the gas volume of the compressor chamber is securely sealed by the higher pressure in the cold room and the associated cooling circuit.
  • temperature and / or pressure-related volume changes in the cooling space are compensated by means of a balancing device by introducing and discharging cooling media into and out of the cooling space.
  • the system according to the invention and the associated method are furthermore independent with regard to the actual size or the volume of the cooling circuit of the compressor device. Regardless of whether there is a large or a small volume of the cooling circuit, the volume can always be completely filled with the aid of the compensation device according to the invention.
  • gas bubbles are also preferably removed from the cooling medium by means of a venting device.
  • This venting device also contributes to ensuring the invention, in comparison to the compressor room higher pressure in the refrigerator at.
  • the above-mentioned compensation device is also designed with a differential pressure regulator for regulating the differential pressure between the cooling space and the compressor space, which has a control piston and a control valve which can be actuated with this.
  • On the control piston acts advantageous on one side of the pressure of the compressor or the pressure prevailing in the compressor chamber.
  • On the other side of the control piston is in particular the pressure of the cooling medium, which, so that it can be held higher than the pressure in the compressor chamber, is increased by an additional force acting on the control piston.
  • the differential pressure regulator is designed with a control piston, which has a first piston chamber fluidly connected to the cooling chamber and a second piston chamber fluidly connected to the compressor chamber and in which the control piston is biased on the side of the second piston chamber resiliently toward the first piston chamber.
  • the resilient bias of this type generates in the first piston chamber an increase in pressure in comparison to the second piston chamber, so that in this way the pressure of the cooling medium, as provided according to the invention, is kept higher than the pressure of the compressor medium.
  • the compensation device according to the invention is further preferably designed with a differential pressure measuring device for measuring the differential pressure between the cooling space and the compressor space.
  • the differential pressure measuring device determines said differential pressure and generates a signal that, with little or no differential pressure with the above-mentioned compensation device, cooling medium is introduced into the cooling circuit into the cooling space.
  • the compensation device is preferably designed with a pressure generator for conveying cooling medium into the cooling space, which, in particular, as explained above, can be actuated by the differential pressure measuring device.
  • the compensation device is preferably designed with a pressure relief for discharging cooling medium from the cooling space, which can be actuated in particular by the above-mentioned control piston.
  • a pressure relief may also advantageously be provided on the pressure generator, a pressure relief valve and / or a safety valve.
  • differential pressure protection provided between the pressure side of the cooling medium and the pressure side of the compressor medium, which ensure a pressure relief by means of a movable wall at an increased differential pressure between these two sides of a compressor according to the invention from a predetermined pressure threshold.
  • the FIGURE shows a highly schematic function diagram of an embodiment of a compressor device according to the invention.
  • a compressor device 10 is designed in the form of a turbo-compressor and in this case has a compressor chamber 12 with a drive (not shown), which is partially integrated therein, of the turbo-compressor.
  • a compressor chamber 12 In the compressor chamber 12 is a (not illustrated in detail) compressor medium.
  • the compressor chamber 12 is surrounded by a partition wall 14 in the form of a tube which encloses the compressor chamber 12 with respect to a cooling space 16.
  • the cooling space 16 is part of a cooling device 18 and includes a (not further illustrated) cooling medium, which can be conveyed by a cooling circuit line 20 out of the cooling space 16 and into this.
  • the cooling medium serves to dissipate heat, which arises mainly through the stator of the electric drive.
  • a cooling pump 22 with an associated cooling pump drive 24 and a cooler 26 are connected in series.
  • a differential pressure control device 28 which has a control piston 30.
  • the control piston 30 separates a first Piston chamber 32 from a second piston chamber 34, wherein in the first piston chamber 32, the pressure of the cooling medium and in the second piston chamber 34, the pressure of the compressor medium is present.
  • the second piston chamber 34 is also a spring element 36, by means of which the control piston 30 is urged resiliently in the direction of the first piston chamber 32. In this way prevails in the first piston chamber 32 in comparison to the second piston chamber 34 higher pressure.
  • a valve 38 is further actuated, by means of the cooling medium from the cooling circuit line 20 can be discharged. This discharging takes place when the volume of the cooling medium in the cooling circuit line 20 in the region between the cooling space 16 and the cooling pump 22 expands (in particular due to heating of the cooling medium). Such expansion of the cooling medium causes the control piston 30 is urged toward the second piston chamber 34 and thereby the valve 38 is opened. The valve 38 then releases a line to a refill and storage device 40 through which cooling medium can drain.
  • the valve 38 is arranged in the installed state in the system at the highest point. This ensures that the valve 38 assumes the function of a venting device and the system is vented via the valve 38.
  • a differential pressure measuring device 42 is provided to detect the differential pressure between the first piston chamber 32 and the second piston chamber 34 by measurement.
  • the differential pressure measuring device 42 has a measuring means 44 and a signal generator 46 of a predefined upper measuring threshold as well as a signal generator 48 of a predefined lower measuring threshold.
  • the signal generator 48 When the differential pressure between the first piston chamber 32 and the second piston chamber 34 decreases below the value of the lower - measured threshold, the signal generator 48 generates an electrical signal, which is passed to a controller 50 of a Nach spallpumpenantriebs 52.

B. with closed check valve 60 or closed shut-off, while the check valve 60 prevents a backflow of coolant from the cooling circuit line 20 back into the storage tank 56 during standstill of the refill 54.
