Abstract
(DE)
Auslassdichtung, die zur Abdichtung eines ersten Druckauslasses und eines zweiten Druckauslasses einer Pumpe eine Dichtungsstruktur (16) aus einem Dichtungsmaterial aufweist, die Dichtungsstruktur (16) umfassend: - einen ersten Dichtsteg (18), der einen für den ersten Druckauslass vorgesehenen ersten Fluiddurchgang (18a) der Auslassdichtung (14) in einer axialen Draufsicht auf die Auslassdichtung umlaufend dicht einrahmt, und - einen zweiten Dichtsteg (19), der in der Draufsicht einen für den zweiten Druckauslass vorgesehenen, seitlich neben dem ersten Fluiddurchgang (18a) gelegenen zweiten Fluiddurchgang (19a) der Auslassdichtung (14) umlaufend dicht einrahmt, - wobei die Dichtungsstruktur (16) die Dichtstege (18, 19) zusammenhängend als Einheit bildet und/oder die Auslassdichtung (14) eine Trägerstruktur (15) umfasst, an der die Dichtstege (18, 19) angeordnet sind.
(EN)
The invention relates to an outlet seal which has a seal structure (16) made of a seal material in order to seal a first pressure outlet and a second pressure outlet of a pump, said seal structure (16) comprising: - a first sealing web (18) which sealingly frames the periphery of a first fluid passage (18a) of the outlet seal (14) in an axial plan view of the outlet seal, said first fluid passage being provided for the first pressure outlet, and - a second sealing web (19) which sealingly frames the periphery of a second fluid passage (19a) of the outlet seal (14) in plan view, said second fluid passage being provided for the second pressure outlet and being placed laterally adjacent to the first fluid passage (18a), wherein - the seal structure (16) forms the sealing webs (18, 19) in a connected manner as one unit and/or the outlet seal (14) comprises a support structure (15) on which the sealing webs (18, 19) are arranged.
(FR)
L'invention concerne une garniture d'étanchéité de sortie qui possède une structure d'étanchéité (16) en un matériau d'étanchéité en vue de rendre étanche une première sortie de pression et une deuxième sortie de pression d'une pompe, la structure d'étanchéité (16) comprenant : une première nervure d'étanchéité (18), qui encadre de manière circonférentielle et étanche un premier passage de fluide (18a), prévu pour la première sortie de pression, de la garniture d'étanchéité de sortie (14) dans une vue de dessus axiale de la garniture d'étanchéité de sortie, et une deuxième nervure d'étanchéité (19) qui, dans la vue de dessus, encadre de manière circonférentielle et étanche un deuxième passage de fluide (19a) de la garniture d'étanchéité de sortie (14), prévu pour la deuxième sortie de pression et situé latéralement à côté du premier passage de fluide (18a). La structure d'étanchéité (16) forme les nervures d'étanchéité (18, 19) en continu sous la forme d'une unité et/ou la garniture d'étanchéité de sortie (14) comporte une structure porteuse (15) sur laquelle sont disposées les nervures d'étanchéité (18, 19).
