Title (EN) SHEAR SEAL ASSEMBLY
(FR) JOINT DE CISAILLEMENT
Abstract: front page image
(EN)A shear seal assembly (65) has an inner sleeve (66) and an outer sleeve (68) with an elastomeric material bonded therebetween. One sleeve (66, 68) has a circumferential groove (74) formed in the exposed wall (76) thereof in which groove (74) an O-ring (78) nests. The assembly is mounted between two telescopic members (28, 38) that have limited relative rotation. The sleeve without the groove (74) is press fit on or in one member (28, 38) and the sleeve (68) with the groove (74) will be spaced from the other member (28, 38) so that the O-ring (78) will extend from the groove (74) into sealing contact with said other member (28, 38). Clips or retainers (82) are provided for seating the grooved sleeve (66, 68) to said other member (28, 38) whereby limited relative rotation or oscillation between the members takes place without rupturing the elastomeric material. The shear seal can be removed without destroying the shear seal structure so that it can be reused.
(FR)Un joint de cisaillement (65) possede un manchon interieur (66) et un manchon exterieur (68) lies par un materiau elastomere intermediaire. Un manchon (66, 68) possede une rainure circonferentielle (74) formee dans sa paroi exposee (76), un joint torique (78) venant se loger dans la rainure (74). L"ensemble est monte entre deux organes telescopiques (28, 38) qui ont un mouvement de rotation relatif limite. Le manchon sans la rainure (74) est ajuste a force sur ou dans un organe (28, 38) et le manchon (68) avec la rainure (74) est espace de l"autre organe (28, 38) de sorte que le joint torique (78) s"etende depuis la rainure (74) en contact d"etancheite avec l"autre organe (28, 38). Des pinces ou des dispositifs de retenue (82) sont prevus pour asseoir le manchon rainure (66, 68) sur ledit autre organe (28, 38), d"ou une rotation ou oscillation relative limitee entre les organes sans qu"il n"y ait rupture du materiau elastomere. Le joint de cisaillement peut etre enleve sans destruction de sa structure de maniere a pouvoir etre reutilise.
