Title
(EN) AIR/OIL SEPARATOR WITH UNITARY TOP END CAP AND FLANGE
(FR) SEPARATEUR AIR/HUILE A BRIDE ET OBTURATEUR D'EXTREMITE SUPERIEURE FORMES D'UN BLOC
Abstract
(EN) An air/oil separator (16) has a filter media pack (25) arranged radially symmetrically about an axis. A bottom end cap (28) is secured to one end of the filter media pack. A top end cap and flange assembly (34) includes a flange and trough member (45) having a flange portion (35) extending radially outwardly from the axis providing a flange for mounting the separator such that the separator is suspended from the flange portion. The flange and trough member (45) also has a trough portion (46) providing an inverted trough within which is a hardenable material secured to the other end of the filter media pack. The flange and trough member (45) is a single unitary member forming both flange and the trough, which eliminates separate flange and trough members which must be welded or brazed together.
(FR) Un séparateur air/huile (16) comporte une garniture (25) à base de milieu filtrant placée symétriquement dans le sens radial autour d'un axe. Un obturateur d'extrémité inférieure (28) est fixé à une extrémité de la garniture à base de milieu filtrant. Un ensemble bride et obturateur d'extrémité supérieure (34) comporte un élément formant bride et auge (45) doté d'une partie bride (35) s'étendant radialement vers l'extérieur depuis l'axe, constituant une bride pour le montage du séparateur, de sorte que ce dernier soit suspendu à la partie bride. L'élément bride et auge (45) comporte également une partie auge (46) constituant une auge inversée dans laquelle une matière durcissable est fixée à l'autre extrémité de la garniture à milieu filtrant. L'élément bride et auge (45) constitue un élément monobloc formant la bride et l'auge, ce qui supprime la nécessité d'utilisation d'éléments bride et auge séparés, lesquels doivent être soudés ou brasés l'un à l'autre.
