ACOPLAMIENTO POR ENCHUFE PARA UNIR UN EXTREMO DE TUBO CON UNA TUBERIA FLEXIBLE O SIMILAR

摘要

A hose coupling wherein the end portion of a pipe is sealingly but separably connected with the end portion of a deformable hose by a tubular connector which has a first section sealingly fitted into the end portion of the pipe and a second section preferably sealingly attached to the end portion of the hose. The second section can abut against the end face of the end portion of the hose or it can surround or extend into such end portion. The connector carries one or more pivotable latching devices with pallets which engage a portion of the external surface of the end portion of the pipe or portions of surfaces bounding openings in the end portion of the pipe. A sealing element in the form of an O-ring or a sleeve is inserted between the internal surface of the end portion of the pipe and the external surface of the respective section of the connector to ensure that the seal between the connector and the pipe remains intact even if one of these parts moves axially relative to the other part. The connector shares all axial movements of the end portion of the hose and is separably connected thereto by mechanical means or is permanently bonded to the hose. The pallet or pallets of the latching device or devices can pivot in planes which include the axis of the coupling.
