Patent ID: 8333219

Claim:
A plug ( 2 , 2 ′, 2 ″) for setting in a pipe ( 4 ), the plug ( 2 , 2 ′, 2 ″) comprising: a shaft ( 8 , 8 ′, 8 ″) having a first end ( 10 ) and a second end ( 12 ); a force transmission body ( 14 ) disposed about the shaft ( 8 , 8 ′, 8 ″) at the first end ( 10 ) thereof, wherein the force transmission body ( 14 ) is connected in a rotatable and axially movable manner to the shaft ( 8 , 8 ′, 8 ″) via a thread connection ( 16 ); a stop body ( 18 ) disposed at the second end ( 12 ) of the shaft ( 8 , 8 ′, 8 ″); and plug construction elements disposed between the force transmission body ( 14 ) and the stop body ( 18 ) including: a first compression body ( 20 , 20 ′) disposed in an axially movable manner about the shaft ( 8 , 8 ′, 8 ″) and in proximity of the force transmission body ( 14 ); a support body ( 22 ) with a conical surface disposed in an axially movable manner about the shaft ( 8 , 8 ′, 8 ″); at least one anchoring body ( 24 ) structured axially movable, hence radially movable, on the outside of the conical support body ( 22 ); a second compression body ( 26 ) disposed in an axially movable manner about the shaft ( 8 , 8 ′, 8 ″); and at least one elastic sealing body ( 28 ) disposed about the shaft ( 8 , 8 ′, 8 ″), wherein the shaft ( 8 , 8 ′, 8 ″) and the first compression body ( 20 , 20 ′) are disposed in direct contact with each other; the shaft ( 8 , 8 ′, 8 ″) and the first compression body ( 20 , 20 ′) are connected in a non-rotational manner via complementary connection elements ( 30 ′, 30 ″); the first compression body ( 20 , 20 ′) is prevented from rotating when the force transmission body ( 14 ) is rotated, thereby ensuring an optimum transmission and control of an activation force for the plug ( 2 , 2 ′, 2 ″).
