ABSTRACT:
In a refrigerant system having a compressor and a pair of coils operatively interconnected to a reversing valve that is adapted to selectively interconnect one of the discharge side and suction side of the compressor to one of the coils while interconnecting the other of the discharge side and the suction side of the compressor to the other of the coils so that one of the coils will act as a condensor and the other coil will act as an evaporator, the improvement wherein the reversing valve has movable ball valve members for affecting the reversing operation thereof under the control of a solenoid operated pilot valve that biases a piston of a piston and cylinder arrangement that is operatively interconnected to the ball valve members.
