Abstract
A service valve assembly that is designed to minimize leakage by reducing the number of leakage paths from the valve assembly. In addition, the service valve assembly is designed to permit connection to many different refrigeration systems and has higher flow capacity. The valve assembly is engageable by current servicing tools so that purchase of new service tools is not required. In the valve assembly, the service connection is designed as part of the shut-off valve and communicates with the condenser side port. Therefore, initial processing through the condenser side port and subsequent processing through the evaporation side port occur through the combined service connection and shut-off valve structure. Once installed, the described valve assembly has one leak path versus two leak paths in known valve assemblies.
