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.
Claims20
An actuator assembly, comprising:
- a housing having a center bore formed therein, a first inner surface, and a second inner surface opposite the first inner surface;
- a first biasing mechanism extending from the first inner surface of the housing;
- a second biasing mechanism extending from the second inner surface of the housing;
- and
- a solid piston at least partially disposed in the housing, wherein the piston
- includes a first end facing the first inner surface of the housing and a second end facing the second inner surface of the housing, and is selectively positionable between a first position within which the first end of the piston is urged toward the first inner surface of the housing, a second position within which the second end of the piston is urged toward the second inner surface of the housing, 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 first end of the piston is spaced apart from the first biasing mechanism when the piston is in the second 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.

An actuator assembly, comprising:
- a housing having a first inner surface and a second inner surface opposite the first inner surface;
- 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 extending from the first inner surface of the housing, and wherein the second chamber includes a second biasing mechanism extending from the second inner surface of the housing,
- wherein the piston includes a first end facing the first inner surface of the housing and a second end facing the second inner surface of the housing, and is selectively positionable between a first position within which the first end of the piston is urged toward the first inner surface of the housing, a second position within which the second end of the piston is urged toward the second inner surface of the housing, 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 first end of the piston is spaced apart from the first biasing mechanism when the piston is in the second 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.

An actuator assembly, comprising:
- a housing having a first inner surface and a second inner surface opposite the first inner surface;
- 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 extending from the first inner surface of the housing and the second chamber has a second biasing mechanism extending from the second inner surface of the housing;
- 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,
- wherein the piston includes a first end facing the first inner surface of the housing and a second end facing the second inner surface of the housing, and is selectively positionable between a first position within which the first end of the piston is urged toward the first inner surface of the housing, a second position within which the second end of the piston is urged toward the second inner surface of the housing, 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 first end of the piston is spaced apart from the first biasing mechanism when the piston is in the second 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.
