Abstract:

In a power element a means (5) for fixing each end of an elastic tubular chamber (2) on the head (6) of a pipe connection union (4) consists of two cylindrical bushings (7, 8) which are interconnected by means of a tenon joint, are located inside the casing (1) and form a central channel, the axis of which coincides with the axis of the casing (1). The walls of the channel in a plane parallel to the longitudinal axis of the casing (1) have the form of two truncated cones facing each other by their larger bases. The generatrix of the conical surface of the channel is essentially parallel to the generatrix of one conical surface of the head (6) of the pipe connection union (4), whereas the other generatrix of the channel is essentially parallel to the generatrix of the other conical surface of the head (6) of the pipe connection union (4).
