ABSTRACT:
A directional flow control or reversing valve for use within a thermodynamic system wherein a working fluid is cycled through a closed-loop fluid circuit having refrigeration elements including a first heat exchanger or coil, a second heat exchanger or coil coupled in series to the first heat exchanger, and a compressor having a high pressure discharge side and a low pressure suction side. The control valve includes distribution and check valving elements that are operable for selectively directing the flow of fluid from the compressor discharge side to the first or second heat exchanger and, respectively, the compressor suction side to the second or first heat exchanger for the reversible operation of the system in alternate heating and cooling modes. The valve includes a housing which is formed as having internal chambers for receiving the valving elements, and fluid ports which open into the housing as couplable in fluid communication with the refrigeration elements of the fluid circuit.
