Publication number: 20170037973Abstract: A seal (6), which is intended for a valve (1) comprising a body (3) and a shutter element (4) movable in a bore (31) of the body under an action of a drive shaft (5), includes at least one elastomeric ring segment (8) having a passage opening (81, 83) for the drive shaft (5). The elastomeric ring segment comprises a surrounding portion (82, 84) arranged around the passage opening (81, 83) and lateral arms (86, 88) which extend in the circumferential direction of the ring while being each connected to the surrounding portion. Starling from each junction (89) between the surrounding portion (82, 84) and a lateral arm (86, 88), the surrounding portion flares outwardly in an axial direction (X-X?) of the ring relative to the lateral arm.Type: ApplicationFiled: December 27, 2013Publication date: February 9, 2017Inventors: Roland LUCOTTE, Gerald LAURENT

Patent number: 8616585Abstract: A pipe joint includes a first pipe that includes a first flange and a second pipe that includes a second flange. A first sleeve is installed within the first pipe and a second sleeve is installed within the second pipe. Further, an annular ring is positioned between the flange of the first pipe and the flange of the second pipe. The annular ring includes a first hub that extends into the first pipe and a second hub that extends into the second pipe. Moreover, a first complementary engagement structure is formed between the first sleeve and the first hub of the annular ring. The first complementary engagement structure provides a first seal interface within the pipe joint. A second complementary engagement structure is formed between the second sleeve and the second hub of the annular ring. The second complementary engagement structure provides a second seal interface within the pipe joint.Type: GrantFiled: October 26, 2011Date of Patent: December 31, 2013Assignees: Saint-Gobain Performance Plastics Corporation, Saint-Gobain Performance Plastics ASTIInventors: Yves Stefani, Roland Lucotte
