Claims
- 1. In a refrigerant system having a compressor and a pair of coils operatively interconnected to a reversing valve for selectively interconnecting one of the discharge side and the suction side of said compressor to one of said coils while interconnecting the other of the discharge side and the suction side of said compressor to the other of said coils so that one of said coils will act as a condensor and the other coil will act as an evaporator, the improvement wherein said reversing valve has four separate movable ball valve means for effecting the reversing operation thereof, said reversing valve having a housing means carrying said ball valve means, a single actuating means carried by said housing means, and a lever pivotally interconnected to said actuating means and to said ball valve means to control said reversing operation thereof.
- 2. In a refrigerant system as set forth in claim 1, said housing means being provided with a pair of port means respectively leading to said coils and having two pairs of valve seats respectively on opposite sides of said port means, said ball valve means controlling said valve seats.
- 3. In a refrigerant system as set forth in claim 2, said ball valve means for each of said pair of valve seats comprising a pair of interconnected spaced apart balls.
- 4. In a refrigerant system as set forth in claim 3, one pair of said spaced apart balls being respectively disposed outboard of their respective pair of valve seats.
- 5. In a refrigerant system as set forth in claim 3, one pair of said spaced apart balls being respectively disposed inboard of their respective pair of valve seats.
- 6. In a refrigerant system as set forth in claim 3, said pairs of interconnected balls being interconnected together to move as a unit.
- 7. In a refrigerant system as set forth in claim 1, said actuator means comprising a fluid operated piston and cylinder means.
- 8. In a refrigerant system as set forth in claim 7, a pilot means carried by said housing means for controlling said fluid operated piston and cylinder means.
