摘要: A shaft sealing structure (12) includes a plurality of V-packings (14a to 14c) that are stacked in multiple stages, and each of the V-packings is formed of a thick-walled annular top portion (16), a thin-walled inner side skirt portion (18), and a thin-walled outer side skirt portion (20). Adjacent ones of the top portions abut against each other, adjacent ones of the inner side skirt portions do not interfere with each other, and adjacent ones of the outer side skirt portions do not interfere with each other.

摘要: Sealing device (1) for a stem (12) of a valve (10) comprising a metal gasket (4) for the valve (10) stem (12), shaped as a half "U" provided with a single sealing lip (44), which has a radially inner surface (442) and a radially outer surface (444), inclined along the radially inner direction, a wedge metal ring (6) positioned inside the half "U" of the metal gasket (4), an elastic element (7) configured to cooperate with said wedge metal ring (6), the elastic element providing the wedge metal ring with an elastic load and a static sealing ring (8). The elastic element (7) is configured for applying a force to the wedge metal ring (6) such that said wedge metal ring (6) applies a contact pressure to the sole sealing lip (44) of the metal gasket (4) shaped as a half "U".

摘要: A two piece valve stem seal assembly including first (114) and second (116) generally cylindrical shells, one of which is partially axially nested or inserted within the other. The valve stem seal assembly also includes an engagement portion (122,134) on the one of the shells for grippingly engaging the other shell in order to substantially prevent or at least minimize the possibility of axial separation of the shells during subsequent assembly into an engine or other valve-containing device. The assembly may also optionally include a discontinuity (654,756) on the one of the shells for axially retaining or axially interlocking the shells in order to substantially prevent or at least minimize such possibility of axial separation.

摘要: Fitting for attachment to a membrane of an inflatable device comprises a mounting adapter (1) to be secured to said membrane. A resiliently deformable part (5c) associated with said mounting adapter is arranged to embrace and hold an initially separate insert (2). The resiliently deformable part (5c) is arranged such that when the mounting adapter is secured to the membrane and exposed to a force exerted by fluid at one of two sides of the membrane, the resiliently deformable part is urged into applying engagement with the insert (2). A variety of different inserts (2) having different valve arrangements can be held by the mounting adapter.

摘要: Die Erfindung betrifft einen Kugelhahn mit einer Schaltkugel (10) zum wahlweisen Sperren oder Freigeben eines fluidführenden Weges (12) innerhalb eines Ventilgehäuses (14), in dem die Schaltkugel (10) über ein Dichtsystem (22) drehbar geführt und mittels einer Schaltspindel (24) betätigbar ist, die das Ventilgehäuse (14) durchgreift, und die über ein weiteres Dichtsystem (30) gleichfalls drehbar im Ventilgehäuse (14) geführt ist. Dadurch, dass das weitere Dichtsystem (30) für die Schaltspindel (24) mindestens eine Lippendichtung (56,58) aufweist, die die Schaltspindel (24) umfaßt, wird die Spindelabdichtung nunmehr nicht mehr über konventionelle O-Dichtringe realisiert, sondern über ein Lippendichtringsystem, wobei die dahingehend eingesetzte Lippendichtung nur eine geringe Vorpressung benötigt, um sicher abdichten zu können, wobei die Dichtvorpressung bei Druck sich noch weiter erhöht.
