Abstract:
A two-part housing interconnects inlet and outlet fittings in fixed relation to form a valve body having an elongate internal chamber. The chamber includes a piston having a seal and cyclically slidable from a closed, flow-restricting position, to an open position. A cam within the chamber engages a follower on the piston outer surface and is driven by an external handle. Certain valve bodies are formed by connecting inlet and outlet fittings. An actuator includes a two-part collapsible cam insertable through the chamber and into a bonnet. Following piston installation, the cam is extended by an external handle to engage a follower on the piston surface. Another actuator includes a body-encircling ring having a cam track on the interior surface. One end of a follower engages the track and another end engages the piston. Rotation of the ring and track drives the piston within the chamber to control liquid flow through the valve.

Claim (Index 10):
A valve, comprising:\n a. a valve body including an inlet fitting coupled with an outlet fitting; b. the valve body defining an elongate chamber having an inlet and an outlet disposed at opposite ends of the chamber; c. a piston disposed within the chamber and including a first seal, the piston being slidable along an axis within the chamber from a closed position in which the first seal engages a seat to restrict flow through the valve to an open position in which the first seal is displaced from the seat to allow flow through the valve; d. a rotatable ring encircling the valve body in coaxial relation to the axis; e. a cam track disposed on the inner surface of the ring whereby rotation of the ring causes rotation of the cam track; and f. a follower having a first end and a second end, the first end engaging the cam track and the second end extending inwardly through the valve body and operably engaging the piston so that the cam track may move the piston between the closed and open position by rotating the ring about the axis.
