Abstract
An actuator assembly is disclosed. The actuator assembly includes a driven component, a coil housing including a first coil and a second coil, and an armature housing including a first armature and a second armature. The first armature is axially fixed to the armature housing, and the second armature is slidably received within the armature housing and axially fixed to the driven component. In a first energized state, the first coil is energized, and the driven component is driven a first predetermined distance towards the coil housing. In a second energized state, the first coil and the second coil are energized, and the driven component is driven a second predetermined distance towards the coil housing.
Claims15
An actuator assembly comprising:
- a driven component;
- a coil housing including a first coil and a second coil, the first coil and the second coil being independently energizable;
- and
- an armature housing including a first armature and a second armature, the first armature axially fixed to the armature housing, and the second armature slidably received within the armature housing and axially fixed to the driven component,
- in a first energized state, the first coil is energized, and the driven component is driven a first predetermined distance from an initial position towards the coil housing, and
- in a second energized state, both the first coil and the second coil are energized, and the driven component is driven a second predetermined distance from the initial position towards the coil housing.
An actuator assembly comprising:
- a driven component;
- a coil housing including a first coil and a second coil, the first coil and the second coil being independently energizable;
- and
- an armature housing including a first armature axially fixed within a first seat and a second armature slidingly supported against a second seat, the first seat and the second seat are axially offset, and the second armature is slidably received within the second seat and is axially fixed to the driven component,
- in a first energized state, the first coil is energized, and the driven component is driven a first predetermined distance from an initial position towards the coil housing until the first armature abuts the first coil, and
- in a second energized state, both the first coil and the second coil are energized, and the driven component is driven a second predetermined distance from the initial position towards the coil housing until the first armature abuts the first coil and the second armature abuts the second coil.
A method of driving a component, the method comprising:
- providing an actuator assembly, the actuator assembly including:
- a driven component;
- a coil housing including a first coil and a second coil, the first coil and the second coil being independently energizable;
- and
- an armature housing including a first armature and a second armature, the first armature axially fixed to the armature housing, and the second armature slidably received within the armature housing and axially fixed to the driven component;
- energizing the first coil such that first armature is driven towards the coil housing, and the driven component is driven a first predetermined distance towards the coil housing;
- energizing the first coil and the second coil such that the first armature and the second armature are driven towards the coil housing, and the driven component is driven a second predetermined distance towards the coil housing.
