Abstract (en)
[origin: US2017058883A1] A membrane vacuum pump has at least one working space which is bounded by a membrane deformable to change the size of the working space and by a wall in which at least one inlet and at least one outlet are formed for a medium which is sucked into the working space which increases in size in so doing in a suction phase and is expelled via the outlet from the working space which decreases in size in so doing in a compression phase. The membrane vacuum pump furthermore has a controllable actuator unit for deforming the membrane by a contactless action on the membrane by means of electrical and/or magnetic fields.
