Abstract:
1. A lip-type shaft seal for sealingly separating pressure compartments, in particular for sealing two components movable relative to one another, comprising: a seal body defining a symmetry axis and made of elastic material which has a Shore A hardness of ≦75, said seal body having a first radial sealing lip for placement in a pocket and terminating in a second axial sealing lip, said radial sealing lip having a sealing edge and bearing against a rotating component, which extends in a direction of the symmetry axis, said axial sealing lip having a sealing edge which, in installed state, rests against a contact surface oriented radially to the symmetry axis; a spring element for urging the sealing edge of the radial sealing lip against the rotating component; and a reinforcing element integrated in a radial sealing portion of the seal body so as to be embraced by one side of the sealing portion, wherein the axial sealing lip extends at an angle of ≧35° in relation to the symmetry axis, when the axial sealing lip has not been installed yet and is under no tension, wherein the axial sealing lip extends from the sealing edge of the radial sealing lip at a length of ≧1.4 mm, when the axial sealing lip has not been installed yet, wherein the axial sealing lip rests against the contact surface at an axial overlap of 0.05 to 0.55 mm, when being installed.
