Abstract
An electromagnetic actuator having at least one electromagnetic actuator unit, the actuator unit comprising a coil and a plunger, which plunger is axially movable relative to the coil via energization of the coil, and the actuator unit being arranged in a housing. In order to achieve a particularly simple design, the plunger is arranged approximately coaxially with the coil according to the invention.
Claims23
An electromagnetic actuator comprising:
- at least two electromagnetic actuator units, each electromagnetic actuator unit including:
- a coil;
- a core concentrically arranged within and rigidly connected to the coil;
- a plunger coaxially aligned with the coil and the core, the plunger configured to translate axially in relation to the coil and the core based on an energization of the coil;
- a stop rigidly connected to the core such that the plunger rests against an at least partially spherical surface of the stop when the plunger is in a first end position proximate to the core;
- and
- a plunger guide coaxially aligned with the coil and the core, the plunger guide configured to slidably receive the plunger,
- wherein each plunger guide is further configured to move in relation to one another.
