Claims8
A valve comprising:
- a valve body having a bore extending through the valve body and defining a longitudinal axis of the valve body;
- a rotatable valve component, rotatable relative to the valve body, rotatably disposed within the bore of the valve body, with a first passage passing through the rotatable valve component;
- a motor disposed within the bore, connected to the rotatable valve component and operable to rotate the rotatable valve component within the valve body, said motor having a longitudinal axis, wherein said longitudinal axis of the motor is aligned parallel with the longitudinal axis of the valve body;
- and
- a motor well, disposed within the bore, wherein said motor well provides a volume within the bore of the valve isolated from the water flow around the motor, with the motor disposed within the motor well;
- a fixed valve component comprising a portion of the body of the valve which surrounds the motor well, with a channel passing longitudinally through the portion of the body of the valve which surrounds the motor well, wherein;
- the rotatable valve component is rotatable to move the first passage into alignment with the channel to allow flow through the channel, and to move the remainder of the rotatable valve component into alignment with the channel to prevent flow through the channel.
