Abstract
A valve diaphragm is provided, comprising: an edge region arranged at a narrow side, in particular a tab protruding beyond a functional region of the valve diaphragm, wherein a recess of the edge region comprises, starting from an opening of the recess, a diameter enlargement; and a plastic body which comprises a transponder and whose fastening portion protrudes through the opening, wherein, by means of a shaping process effected in the diameter enlargement of the recess, in particular by hot caulking, at least one region of the fastening portion at least partially fills the diameter enlargement.
Claims18
A method of production of a valve diaphragm, wherein the valve diaphragm comprises:
- an edge region arranged at a narrow side, wherein a recess of the edge region comprises, starting from an opening of the recess, a diameter enlargement;
- and a plastic body which comprises a transponder and whose fastening portion protrudes through the opening, wherein at least one region of the fastening portion at least partially fills the diameter enlargement by means of hot caulking executed in the diameter enlargement of the recess, and wherein the at least one region of the fastening portion secures the plastic body in a positive-locking manner to the edge region, wherein the method comprises:
- producing a main body of the valve diaphragm, wherein the diameter enlargement is implemented as a blind hole with an inner diameter in the main body which decreases at least in portions towards the bottom of the blind hole;
- penetrating a passage in a region of the diameter enlargement to form the recess;
- arranging a blank fastening portion of a plastic body blank in the region of the diameter enlargement, wherein the fastening portion is guided through the opening;
- and
- shaping the blank fastening portion to produce the at least one region of the fastening portion in the diameter enlargement.
A valve diaphragm comprising:
- an edge region arranged at a narrow side;
- and
- a plastic body comprising a head with a transponder arranged therein, wherein a fastening portion arranged within the edge region projects from the head, and wherein the fastening portion comprises:
- at least two first positive-locking portions arranged on opposite sides of a central longitudinal axis (U) of the plastic body and tapering in a distal direction;
- and
- at least two second positive-locking portions arranged on opposite sides of the central longitudinal axis (U) of the plastic body and projecting in a proximal direction, wherein surfaces oriented in the distal direction of the first positive-locking portions each enclose a smaller angle with the central longitudinal axis (U) than surfaces oriented in the distal direction of the second positive-locking portions enclose with the central longitudinal axis (U).
A valve diaphragm comprising:
- an edge region arranged at a narrow side, wherein a recess of the edge region comprises, starting from an opening of the recess, a diameter enlargement;
- and
- a plastic body which comprises a transponder and whose fastening portion protrudes through the opening, wherein at least one region of the fastening portion at least partially fills the diameter enlargement by means of hot caulking executed in the diameter enlargement of the recess, and wherein the at least one region of the fastening portion secures the plastic body in a positive-locking manner to the edge region.
