Linear actuator and method for operating such a linear actuator

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. 本发明涉及种线性致动器。该线性致动器包括双室螺线管泵，该双室螺线管泵包括至少个泵线圈、多通阀以及至少个泵电枢，通过给至少个泵线圈供电能够使该泵电枢移动；并且该双室螺线管泵设置有切换电枢，多通阀能够借助于该切换电枢而切换，并且通过给至少个泵线圈供电能够使该切换电枢移动。在本方法中，通过给泵线圈供电而使切换电枢和泵电枢都移动。
