PCT No. PCT/SU89/00101 Sec. 371 Date Jan. 18, 1990 Sec. 102(e) Date Jan. 18, 1990 PCT Filed Apr. 18, 1989 PCT Pub. No. WO89/11023 PCT Pub. Date Nov. 16, 1989.In a powered member, a device for attaching each end of a flexible tubular chamber to a head of a nipple is formed by a pair of cylindrical bushings interconnected by means of a tenon and mortise joint which are located in the casing and define a central passage having its axis aligned with the axis of the casing. Walls of the passage in a plane drawn in parallel with the longitudinal axis of the casing are in the form of a pair of truncated cones having their larger bases facing towards each other. One generatrix of the conical surface of the passage extends substantially in parallel with generatrix of one conical passage of the head of the nipple and the other generatrix of the passage extends substantially in parallel with the generatrix of the other conical passage of the head of the nipple. |
