Abstract
A refrigerant powered actuated ball valve for use in the fluid circuit of a refrigeration or air conditioning system which can be remotely controlled by a low amperage control signal is disclosed. The actuated ball valve harnesses the pressurized refrigerant from the fluid circuit in which it is installed as the primary power medium to actuate the valve. The valve includes actuation means with a manifold having an inlet port which is in constant fluid communication with a high-pressure side of the fluid circuit. Pressurized refrigerant supplied to the manifold is branched to a series of fluid channels running through the manifold. Exhaust port operators are mounted in conjunction with the manifold to connect the actuation means to the low-pressure side of the fluid circuit and to direct the flow of pressurized refrigerant to either an exhaust port or the manifold. A reciprocal member disposed within the manifold engages a pinion such that a linear displacement of the reciprocal member causes a corresponding angular displacement of the pinion member. Cycling of the ball valve between an opened position and a closed position is achieved when the pressurized refrigerant is applied to …
