Abstract
The linear actuator comprises a double-chamber solenoid pump comprising at least one pump coil, a multi-way valve and at least one pump armature that can be moved by energizing the at least one pump coil and is provided with a switching armature by means of which the multi-way valve can be switched and which can be moved by energizing the at least one pump coil. In the method, both the switching armature and the pump armature are moved by energizing the pump coil.
Claims18
A linear actuator comprising:
- a solenoid pump having:
- at least one pump coil;
- a multi-way valve;
- at least one pump armature that is movable by energizing the at least one pump coil;
- and
- a switching armature, by which the multi-way valve is switchable, the switching armature being movable by energizing the at least one pump coil.
A method for operating a linear actuator, the linear actuator comprising a solenoid pump, the solenoid pump having at least one pump coil, a multi-way valve, at least one pump armature that is movable by energizing the at least one pump coil, and a switching armature, by which the multi-way valve is switchable, the switching armature being movable by energizing the at least one pump coil, the method comprising:
- setting the switching armature in a predetermined position in relation to a position of the multi-way valve, the setting comprising the energization of the at least one pump coil;
- and
- moving the pump armature while maintaining the predetermined position, the moving of the pump armature while maintaining the predetermined position comprising energizing the at least one pump coil.
