A flexible hose with connect flange and a method for obtaining such a hose. The flexible hose () whereof the elastomer wall () is reinforced by at least a main carcass () comprises flexible cables, including at least at one of its ends an annular flange (), provided with longitudinal perforations, whereto is fixed at least the main carcass, the flange having an external diameter not greater than the external diameter of the hose wall proximate to the flange. The flange comprises perforations () emerging on one or more indentation(s) () provided on the outer surface () of the hose wall and whereof the dimensions enable to house therein at least linking elements () externally accessible for abutting connection of pipes without interposition of an intermediate component between their respective flanges.

Flexible hose with connect flange and method for obtaining same

A flexible hose which makes possible the early visual detection of a malfunction, can have a structure which allows a localized deformation in specified zones. This structure can have a combination of at least one radial expansion zone, and at least one compensation zone, wherein a localized deformation can occur as soon as the leak pressure of the leaking fluid reaches a threshold value which is only a fraction of the operating pressure of the fluid being transported through the hose.

An internal combustion engine having a power generating device, and a transmission link connecting the power generating device to an accessory operated by the power generating device, the transmission link being tensioned by a tension adjusting device which pivots, during tension relaxation, around an imaginary center of rotation, and during a tension increase, around a stop, such that the two elastic rigidities achieved for both rotations are in a ratio of at least two.
