SLIDE RING SEAL

摘要

The invention relates to a slide ring seal, especially a slide ring seal for a housing, comprising a counter-ring that can be connected to a rotary shaft in a fixed and sealed manner, and two slide rings between which the counter-ring is coaxially arranged, said rings being provided with slide surfaces such that the rings can rotate in relation to each other in a sealed manner. At least one channel (12) extending especially in the radial direction is arranged in the counter-ring (10), one opening of said channel being oriented towards the shaft (W) and the other opening being fluidically connected to a retaining chamber. The invention also relates to a slide ring seal comprising a counter-ring that can be connected to a rotary shaft in a fixed and sealed manner, and two slide rings between which the counter-ring is coaxially arranged, said rings being provided with slide surfaces such that the rings can rotate in relation to each other in a sealed manner. The counter-ring and the slide rings are covered by an annular housing which is coaxially arranged in relation to the rings, the rotation of said housing in relation to the rings being prevented by a locking element. Said locking element comprises at least one rod (14) on which an abutment element (17) comprising an abutment surface is rotatably arranged, the abutment surface co-operating with a flat counter-abutment (18).
