Abstract
An actuator assembly comprises a housing having a piston at least partially disposed therein. The actuator assembly includes at least one biasing mechanism disposed within the housing to selectively position the piston between a first position, a second position, and a third position located between the first and second positions.
Claims21
1-15. (canceled)
An actuator assembly, comprising:
- a housing having a center bore formed therein;
- a first biasing mechanism disposed in the housing;
- a second biasing mechanism disposed in the housing;
- and
- a solid piston at least partially disposed in the housing, wherein the piston includes a first end and a second end, and is selectively positionable between a first position, a second position, and an intermediate position between the first position and the second position, and wherein the first end of the piston contacts the first biasing mechanism when the piston is in the first position, and the second end of the piston includes an actuating member extending outwardly away from the first biasing mechanism, wherein the piston is spaced apart from the first biasing mechanism when the piston is in at least one of the second position and the intermediate position, and wherein the second end of the piston contacts the second biasing mechanism when the piston is in the first position, the second position, and the intermediate position.
2 more elements
An actuator assembly, comprising:
- a housing;
- and
- a one-piece solid piston at least partially disposed in the housing, wherein the piston divides the housing into a first chamber and a second chamber, wherein the first chamber includes a first biasing mechanism disposed therein, and wherein the second chamber includes a second biasing mechanism.
An actuator assembly, comprising:
- a housing;
- a one-piece solid piston at least partially disposed in the housing, wherein the piston divides the housing into a first chamber and a second chamber, and wherein the first chamber has a first biasing mechanism disposed therein and the second chamber has a second biasing mechanism disposed therein;
- and
- a sealing member disposed about the piston, wherein the sealing member militates against a flow of at least one fluid directly from one of the first chamber and the second chamber into a remaining one of the first chamber and the second chamber.
