A commercial refrigeration system has a control system which distributes intelligence to increase granularity of the control and simplify wiring, assembly and installation. Compressors of the refrigeration system each have a bus compatible compressor safety and control module including a processor and sensors. All control and safety modules communicate over a single power and communications line with the controller, providing digital transmissions to the controller of measurements taken by the sensors. The information provided may include that the compressor is outside of a specific safety parameter, so that the controller knows not only that a safety parameter has been traversed, but exactly which one. The control and safety modules are capable of executing commands from the controller to cycle the compressors. The control and safety modules preferably contain sufficient intelligence to continue system operation upon failure of the controller. A compressor is also disclosed which has an intelligent control and safety module. The compressor also houses control and safety devices within a hermetically or semi-hermetically sealed shell. A condenser controller is also disclosed that is capable of communicating with the controller to affect intelligent control of one or more compressor fans. A valve controller is disclosed that is capable of communicating with the controller to facilitate distributed control of a system control valve with minimal wiring. A branch controller also communicates with the controller, resulting in distributed control of a refrigeration branch with minimal wiring required. Display/fixture control is achieved using display and control modules that collect data from a plurality of sensors on a common wiring harness. Wiring is also reduced by providing for wireless communication interfaces.

A device to reduce vibrations in a hydraulic force transfer system which has a master cylinder and a slave cylinder connected to the master cylinder via a fluid column, with a housing and a membrane, the membrane having an edge by which it is attached to the housing, wherein the housing and the membrane delimit a chamber which can be connected via a connection to the master cylinder and via a further connection to the slave cylinder, so that the membrane can be pressurized hydraulically by the fluid column between the master cylinder and slave cylinder, and wherein the membrane, at least in a rest state of the hydraulic force transfer system, is pressed by means of a spring element against the direction of the hydraulic pressurization of the membrane against a support surface on the chamber side. 2. A device according to claim 1, wherein the chamber has a base and the housing has a projection extending centrally from the base of the chamber in the direction of the membrane, said projection forming said support surface. 3. A device according to claim 1, wherein the housing has an annular groove surrounding the chamber concentrically to hold a sealing element lying on the membrane, which seals the chamber against the environment. 4. A device according to claim 3, wherein the housing, between the chamber and the annular groove, has a ring-cylindrical section on which the membrane lies at least in the rest state of the hydraulic force transfer system, wherein the ring-cylindrical section has at least one connecting channel which connects the chamber with the annular groove. 5. A device according to claim 4, wherein the ring-cylindrical section has a face surface, and wherein said face surface and the support surface on the projection lie in one plane, so that the membrane loaded by the spring element is held flat in the rest state of the hydraulic force transfer system. 6. A device according to claim 1, wherein the housing is substantially pot-like, and wherein on the substantially pot-like housing is provided a cover which, together with the housing, clamps the membrane at its edge, wherein the spring element rests with its end facing away from the membrane on the cover. 7. A device according to claim 6, wherein the cover is attached to the housing by means of a threaded connection, wherein the cover has an external threaded section which can be screwed into an internal threaded section of the housing. 8. A device according to claim 7, wherein the threaded connection is formed as both sawtooth and round thread-like such that at least the internal threaded section of the housing is rounded in a round thread-like manner at the external diameter of the thread profile and at the internal diameter of the threaded profile has a rounded sawtooth thread-like form. 9. A device according to claim 6, wherein the cover has a central receiving and guiding section for the spring element. 10. A device according to claim 1, wherein the spring element is a coil compression spring. 11. A device according to claim 10, wherein the spring element is surrounded concentrically by a flange sleeve which has a ring collar arranged between the end of the spring element facing the membrane and the membrane. 12. A device according to claim 11, wherein the face of the ring collar facing the membrane is formed as a flat face. 13. A device according to claim 11, wherein the flange sleeve is guided axially mobile in the receiving and guiding section of the cover. 14. A device according to claim 13, wherein the flange sleeve at its end facing away from the membrane has on its outer periphery a peripheral projection while the receiving and guiding section of the cover at its end facing the membrane has on its inner periphery a peripheral projection, wherein the peripheral projection of the flange sleeve has an external diameter which is slightly larger than the internal diameter of the peripheral projection on the receiving and guiding section of the cover. 15. A device according to claim 1, wherein the membrane is made of spring steel. 16. A device according to claim 15, wherein the ratio of diameter to thickness of the membrane is between 40 and 160. 17.
