摘要： A pressure equalising device for a housing, including an inside, an outside, and a lattice-like cage having a gas passage opening. The gas passage opening connects the inside and the outside in a differential pressure-dependent and flow-conducting manner. The gas passage opening is covered by a gas-permeable membrane which includes at least one nonwoven layer. The nonwoven layer includes fibers which are substantially completely sheathed by a sheath of an elastomer.

摘要： A plug-in piece 1 for sealing connection of two mutually assigned cylindrical surfaces includes an essentially tubular support body 2, which on its ends exhibits annularly encircling sealing elements, which can be made to engage to produce a sealing connection with the cylindrical surfaces to be sealed, wherein at least one of the sealing elements is configured as an annularly encircling sealing bead 3, 30 on the outer surface of the support body 2, with a spherically curved sealing surface. Provision is made that the spherical radius of the sealing surface (3, 30) is chosen so that the center of the sphere is roughly at the axis of support body (2) symmetry. Thus, the compression forces are ensured to remain largely constant, independent of the angular setting over the entire surface of the sealing bead.
