Hose-connection fitting for a pressure hose

摘要

The invention relates to a hose-connection fitting for a pressure hose, having a nipple which projects into the interior of the hose end and having a sleeve which coaxially encloses the hose end, presses it radially against the nipple and thus fixes it axially, at least one elastic sealing ring being arranged between the outer wall of the nipple and the inner wall of the hose end. In order to obtain leaktightness, even after long usage and extreme operating conditions, it is proposed that the sealing ring be supported in the direction of the hose and fitting axis, on the one hand, against a flange-like or step-like encircling radial protrusion on the outer wall of the nipple and, on the other hand, against a radial constriction of the sleeve or of an intermediate part which is rigidly connected to the sleeve, and that it be possible to push the nipple and sleeve together relative to one another, by the internal hose pressure, in the direction of the hose and fitting axis to the extent to which the sealing ring can be elastically deformed in said direction. According to a further variant, the function of the sealing rings is assumed by parts of the hose wall.
