sleeve for a group of estate with characteristic pompante and procedure for its implementation.

摘要

complex required for use with two elements relatively mobile to close to estate, and comprising a group of bound primary and associated hose wear.the group comprises a shell and a primary sealing element with at least a part of keeping fit to be called an exact contact of fluid with a surface of the sealing sleevewear.the latter has a generally cylindrical configuration having a surface formed by cold flow of metal, and the configuration includes at least one element of pumping water and airhaving been a part odinamico off radially from the rest of the surface of the cylindrical part of the sleeve wear.the process includes positioning a sleeve of wear in a mold of molded wire and displacement of a punch for forming along the cape of the sleeve wear for theungare cape while reducing its thickness.and at the same time to ensure that the metal flow cold in order to create a pattern on the surface of the mantle that is complementary to the configuration of the mold drawing.
