  • Patent number: 11802622
    Abstract: A shaft seal, in particular a radial shaft seal, has a seal element that is provided with a seal section that under elastic deformation contacts the outer side of a mounting sleeve. The shaft seal has a grease ring located on the mounting sleeve wherein the grease ring is arranged axially adjacent to the free end of the seal section on the mounting sleeve. For installation, grease ring and seal section are pushed by a mounting tool onto the shaft and the seal section on the shaft is pushed onto the grease ring in such a way that the grease of the grease ring is distributed between the seal section and the shaft.

  • Patent number: 11792944
    Abstract: The valve for pressure compensation and/or for emergency venting of a container, preferably of a housing of a vehicle battery, has a housing (6) with an inlet (6a) that is closable by at least one valve element (23) subjected to a closing force in a first position. The housing (6) is at least partially gas-permeable and preferably water-tight, and has at least one outlet (26) which is located behind the valve element (23) when the valve element (23) assumes its first position. So that in case of a malfunction even larger quantities of gas can be guided to the exterior through the valve, is the valve element for an increased pressure surpassing the closing force at the inlet (6a) is adjustable in the direction toward a second position against the closing force, in which the valve element (23) at least partially opens the outlet (26) such that the outlet (26) is directly connected in flow communication with the inlet (6a).

  • Patent number: 11719343
    Abstract: A radial shaft seal has an elastomeric sealing lip with an inner side facing a shaft to be sealed. The sealing lip has a first circumferential ring arranged at the inner side and resting against the shaft to seal a medium side from an air side. Return conveying elements are arranged circumferentially about the sealing lip at the inner side and at a side of the first circumferential ring facing the air side. They return leakage medium, independent of a rotational direction of the shaft, to the medium side. A second circumferential ring at the inner side is positioned at a side of the return conveying elements facing the air side. The first circumferential ring is an elevation with depressions, also formed as elevations, distributed circumferentially thereabout. The depressions extend toward the second circumferential ring and are positioned, respectively, between two of the return conveying elements neighboring each other.

  • Patent number: 11603933
    Abstract: A radial shaft seal for a shaft to be sealed operating at high rotational speeds and circumferential speeds in both rotational directions has a sealing lip with a first circumferential ring and a second circumferential ring. The first circumferential ring is resting seal-tightly against the shaft to be sealed and seals the medium side. At the side of the first circumferential ring facing the air side, there are first return elements that convey leakage medium back to the medium side. The second circumferential ring is provided at the side of the first circumferential ring facing the air side and second return elements are provided at its air side. The second return elements guide medium that has passed underneath the second circumferential ring back underneath the second circumferential ring to the medium side.
