Abstract
A fluid choke may include a housing and a shuttle configured to move within an interior chamber of the housing. The housing may have a fluid inlet channel and a fluid outlet channel. The shuttle may have a gate connected to an end of the shuttle and the gate may be configured to mate with a seat located in the housing at the fluid outlet channel. The shuttle may be moved within the interior chamber by a pressurized hydraulic fluid configured to apply a hydraulic pressure to a peripheral portion of the shuttle, an inner portion of the shuttle, and the gate.
Claims18
An apparatus comprising:
- a housing having a plurality of fluid channels therethrough comprising at least an inlet channel connected to an outlet channel via a fluid passageway such that fluid is flowable from the inlet channel through the fluid passageway to the outlet channel;
- a shuttle configured to move within the housing, the shuttle having an inner surface and a total length defined between a first end of the shuttle and a second opposite end of the shuttle, wherein the first end of the shuttle has an end surface facing the outlet channel;
- a bonnet coupled to the housing;
- a gate extending outwardly away from the end surface of the shuttle facing the outlet channel towards the outlet channel, wherein the gate has a first end directly facing the outlet channel and a second, opposite end facing the shuttle, wherein the gate tapers inwardly towards the first end;
- and
- a hydraulic fluid chamber at least partially defined by the bonnet and the inner surface of the shuttle and configured to apply hydraulic pressure to both the bonnet and the second end of the gate,
- wherein the end surface of the first end of the shuttle is disposed within the fluid passageway between the inlet channel and the outlet channel, and
- wherein the hydraulic fluid chamber is configured to apply hydraulic pressure to the bonnet directly and to the second end of the gate directly.

A method comprising:
- mounting a shuttle to be movable inside a housing that comprises at least an inlet channel, an outlet channel and a fluid passageway connecting the inlet channel and the outlet channel such that fluid is flowable from the inlet channel throughout the fluid passageway to the outlet channel, the shuttle being movable in a first direction and in a second, opposite direction, the shuttle including a peripheral portion and an inner portion, wherein the shuttle has a total length defined between a first end of the shuttle and an opposite second end of the shuttle and the first end of the shuttle has an end surface facing the outlet channel of the housing, wherein the inner portion is located distally farther in the first direction than the peripheral portion;
- covering at least a portion of the end surface of the shuttle, that faces the outlet channel, with a shuttle nut;
- and
- moving the shuttle within the housing by directing pressurized hydraulic fluid to the peripheral portion and the inner portion of the shuttle,
- wherein the end surface of the first end of the shuttle is disposed within the fluid passageway between the inlet channel and the outlet channel.

- a housing having a plurality of fluid channels therethrough comprising at least an inlet channel connected to an outlet channel via a fluid passageway such that fluid is flowable from the inlet channel through the fluid passageway to the outlet channel;
- a shuttle configured to move within the housing, the shuttle having an inner surface and a total length defined between a first end of the shuttle and a second opposite end of the shuttle, wherein the first end of the shuttle has an end surface facing the outlet channel;
- a bonnet coupled to the housing;
- a gate extending outwardly away from the end surface of the shuttle facing the outlet channel towards the outlet channel, wherein the gate has a first end directly facing the outlet channel and a second, opposite end facing the shuttle, wherein the gate tapers inwardly towards the first end;
- a hydraulic fluid chamber at least partially defined by the bonnet and the inner surface of the shuttle and configured to apply hydraulic pressure to both the bonnet and the second end of the gate;
- and
- a shuttle nut configured to at least partially secure the gate to the shuttle and wherein the hydraulic fluid chamber is at least partially defined by the shuttle nut,
- wherein the end surface of the first end of the shuttle is disposed within the fluid passageway between the inlet channel and the outlet channel, and
- wherein the gate is fixed relative to the shuttle, wherein the second end at least partially defines the hydraulic fluid chamber.
