Abstract

Gasket for fluid to apply between two rotating elements with respect to the other, comprising an annular body that can be coupled to one of said elements, a flexible and circumferential lip formed in said body and protruding from it so that a joint edge of said lip is apply against the other element; whose lip edge is defined by the common edge of two angularly arranged annular surfaces; a pumping configuration provided on one of said surfaces and that is effective to push the fluid towards said lip edge during the relative rotation of said elements; and a plurality of discontinuities provided around the circumference of said lip edge so that, in use, an interrupted coupling is defined between said lip edge and the second element and each interruption is formed in such a way as to define a passage through which can transfer fluid from one side to the other of said lip.
