  • Dual restrictor shut-off valve for pressurized fluids of air cooling/heating apparatus
    Patent number: 6560987
    Abstract: A shut-off valve for pressurized fluids in an air cooling/heating apparatus that includes at least one condenser and at least one fluid evaporator communicating with each other by a pipe. The valve includes two ducts each containing a restrictor coaxially formed with a capillary designed to cause rapid expansion of the fluid when it emerges from the capillary, thus allowing expansion of the fluid in either the heating or cooling mode. The valve further includes a duct for sampling the pressurized fluid before expansion during operation in either the heating or cooling mode.
    Type: Grant
