  • Patent number: 11530754
    Abstract: The disclosure relates to a sealing diaphragm and a check valve comprising a sealing diaphragm for fluid technology applications. A sealing diaphragm for fluid technology applications is to be provided, which is economical and constructionally simple to produce, which can be used as a closing means for a check valve and with which unwanted interfering noise can be prevented during operation. The object of the disclosure is achieved by a sealing diaphragm with a flat, flexible sealing section, which can be bent or curved with a fluid pressure, wherein at least one resilient frictional tooth is provided on or next to the surface of the sealing section at a distance from an edge of the sealing section, designed and arranged in such a way that it forms an angle between 30° and 150° with the sealing section and it tilts together with the bending or curving movement of the flat sealing section, wherein the frictional tooth has a contact surface on a side orientated in the tilting direction.
