Abstract
Methods, apparatus, systems and articles of manufacture are disclosed that produce a pneumatic actuator end cap having an integral volume booster. An example pneumatic actuator end cap includes a first cavity to provide a first fluid passageway to receive a pressurized fluid from a source external to the pneumatic actuator end cap, a second cavity to provide a second fluid passageway to route the pressurized fluid to an internal chamber of a pneumatic actuator in which a piston is disposed, and a third cavity containing a fluid valve to control a flow of the pressurized fluid between the first fluid passageway and the second fluid passageway.
Claims20
A pneumatic actuator end cap comprising:
- a first cavity to provide a first fluid passageway to receive a pressurized fluid from a source external to the pneumatic actuator end cap;
- a second cavity to provide a second fluid passageway to route the pressurized fluid to an internal chamber of a pneumatic actuator in which a piston is disposed;
- and
- a third cavity containing a fluid valve to control a flow of the pressurized fluid between the first fluid passageway and the second fluid passageway.
A pneumatic actuator system comprising:
- a cylinder including a piston;
- and
- an end cap coupled to the cylinder, the end cap including cavities defining at least a portion of a pneumatic volume booster, the cavities to provide fluid passageways to control a flow of pressurized fluid within the system.
A method comprising:
- forming a first cavity of a portion of a pneumatic volume booster, the first cavity to provide a first fluid passageway to receive a pressurized fluid from an external source;
- forming a second cavity of the portion of the pneumatic volume booster, the second cavity to provide a second fluid passageway to route the pressurized fluid to an internal chamber of a pneumatic actuator;
- and
- forming a third cavity of the portion of the pneumatic volume booster, the third cavity to control a flow of the pressurized fluid between the first fluid passageway and the second fluid passageway.
