  • Patent number: 10682845
    Abstract: A film transducer has a holding part, an electroactive composite structure which includes at least one deformable carrier and at least two electrodes arranged on opposite sides of the deformable carrier, and a load application member which is mounted to the composite structure. The holding part engages two ends of the composite structure facing away from each other and the load application member is arranged between the two ends of the composite structure.
    Type: Grant

  • Patent number: 10422435
    Abstract: A diaphragm valve including an axially driven valve spindle provides a pressure member, which allows to directly couple the diaphragm to the valve spindle. The same pressure member may always be used for coupling, irrespectively of the type of fastener, which is integrated in the diaphragm.

  • Patent number: 10241500
    Abstract: A film transducer has a holding part and an electroactive multilayer composite structure including at least two deformable carriers which are each coated on at least one side with a planar electrode. The multilayer composite structure has an elongated basic shape and being clamped on its shorter sides in a fixing section in the holding part while its longer sides are free, the electrodes of the multilayer composite structure being alternately connected at the ends clamped in the holding part to a contact element which is arranged in the fixing section.

  • Patent number: 9638339
    Abstract: A diaphragm valve comprises at least one valve body which has at least one inlet, at least one outlet, at least one flow channel and at least one shutoff web dividing the flow channel into channel portions. The diaphragm valve furthermore comprises a diaphragm which rests on a circumferential sealing seat of the valve body, and a drive having a drive housing, the drive being coupled to the diaphragm to press the diaphragm against the shutoff web for closing the valve. The diaphragm valve furthermore comprises a fastening unit for detachably locking the drive to the valve body, the fasting unit having a bayonet cap and an additional central retightening unit by means of which an axial tightening force is generated.
