Abstract
A valve apparatus having a valve body configured with a flow passage. There is a main piston movably disposed within the flow passage, and configured to move to and from a first piston position to a second piston position. The valve apparatus also has a movable member movably disposed within the valve body, the movable member comprising: a no-go position for stopping movement of the main piston, and a go position to facilitate movement of the main piston.
Claims19
A valve apparatus comprising:
- a valve body comprising a flow passage;
- a main piston movably disposed within the flow passage, the main piston configured to move to and from a first piston position to a second piston position, and the main piston having an extended piston end and an inner piston passageway;
- a chamber formed in the valve body, and comprising an at least one movable piston;
- a blade coupled with the at least one movable piston;
- a movable member movingly disposed within the valve body, the movable member comprising:
- a shoulder for stopping movement of the main piston by abutting the extended piston end, and an opening for the extended piston end to pass therethrough;
- wherein movement of the valve apparatus results in movement of the movable member in a sufficient manner to allow the main piston to move from the first position to the second position, and wherein the second position corresponds with fluid pressure entering the chamber to the movable piston and extending the blade.

A valve apparatus comprising:
- a valve body comprising a flow passage;
- a main piston movably disposed within the flow passage, the main piston configured to move to and from a first piston position to a second piston position, and the main piston having an extended piston end and an inner piston passageway;
- a chamber formed in the valve body, and comprising an at least one actuatable device;
- a movable member movable disposed within the valve body, the movable member comprising:
- a no-go position for stopping movement of the main piston, and a go position to facilitate movement of the extended piston end;
- wherein rotation of the valve apparatus results in rotation of the movable member in a sufficient manner to allow the main piston to move from the first position to the second position, and wherein the second position corresponds with fluid pressure entering the chamber to the actuatable device.

A valve apparatus comprising:
- a valve body comprising a flow passage, and a first housing coupled with a second housing;
- a main piston movably disposed within the flow passage, the main piston configured to move to and from a first piston position to a second piston position, and the main piston having an extended piston end and an inner piston passageway;
- a chamber formed in the first housing, and comprising an at least one actuatable device;
- a movable member movably disposed within the second housing, the movable member comprising:
- a no-go position for stopping movement of the main piston, and a go position to facilitate movement of the extended piston end;
- wherein predetermined movement of the valve apparatus results in movement of the movable member in a sufficient manner to allow fluid pressure to act on the main piston to move from the first position to the second position, and wherein the second position corresponds with fluid pressure entering the chamber to the actuatable device.
