  • Patent number: 11703127
    Abstract: A seal assembly includes: a seal element; a part to be sealed; and a measuring arrangement for monitoring an aging of the seal element. The seal element is held on the part so as to provide a contact stress between the seal element and the part. The seal element has a contact face with which the seal element bears against the part. At least one measuring component of the measuring arrangement is integrated in each case into the seal element and into the part. The contact face of the seal element has a surface geometry with depressions.

  • Patent number: 10539246
    Abstract: A pressure equalization element for a housing, such as a lithium-ion accumulator, includes a membrane and at least two parallel non-return valves. The membrane is connected in series to the non-return valves, which are positioned opposite each other. The non-return valves are formed by two valve plates and a valve membrane. The plates define at least one outlet chamber and at least one inlet chamber which each have a respective entry opening and exit opening. The membrane is positioned between the plates and includes at least two valve dampers, the entry openings of the inlet and outlet chambers sealed by a respective damper. Pressure equalization elements of this type can thus be cost-effectively and logically implemented via few components, while avoiding loose components. Such elements can be included in, for example, a housing, battery cell module, or motor vehicle.
