  • Refrigerant thermostatic valve
    Patent number: 5974827
    Abstract: The present invention provides a valve for use in a lubrication oil circulation system associated with the compressor of a refrigeration system, which valve has internal operating components which can be removed through a sealable access opening in the wall of the body of the valve, thus allowing the operating components of the valve to be inserted into and removed from the valve body through the access opening. This permits the valve body to be connected to the pipework of the circulation system by welded joints in place of the but joints used hitherto. The invention also provides a lubrication oil circulation system incorporating a valve mechanism of the invention.
