ABSTRACT:
Apparatus is disclosed for serving as both a reversing valve and an expansion device in a refrigeration circuit. A valve gate having passageways to direct refrigerant between the indoor and the outdoor heat exchangers to effect the function of a reversing valve is disclosed. In addition, the valve gate has multiple flow restriction devices which are selectively incorporated within a refrigeration circuit between the indoor heat exchanger and the outdoor heat exchanger to effect the appropriate amount of flow restriction dependent upon the mode of operation of the unit. These two functions may be incorporated into a single valve or they may be separated such that the separate functions are performed by separate valves. A cylindrical valve gate and multiple passageways for connecting the appropriate lines in a refrigeration circuit are described. The valve is rotated by a combination of an electromagnet spaced about the valve gate and a permanent magnet located within the valve gate.
