Abstract

End fitting or armature for multi-channel hoses having a positioning plate and a guiding plate extending perpendicularly to the longitudinal axis of the hose and apertured to receive hose coupling elements. Means are provided for varying the axial spacing of the plates. A resilient element is disposed between the plates, a part of which seats in a groove formed in the internal surface of the end fitting when the plates are pulled towards each other under load.

Claims

1. An end fitting for a multi-channel hose, comprising a hollow body for positioning and retaining coupling elements of individual hoses;

a positioning plate and a guiding plate respectively disposed within said body, at right angles to the longitudinal axis of the end fitting;

respective apertures defined in said plates for receiving said coupling elements;

adjusting means for varying the axial distance between said plates; and

means disposed between said plates for resiliently spacing them apart, at least a part of said spacing means being farther from the longitudinal axis, when said plates are pulled towards each other under load, than in an unloaded state;

wherein a groove is defined in the internal surface of said body, and said part of the spacing means is engaged in said groove when said plates are pulled towards each other.

2. The end fitting as defined in claim 1, wherein said adjusting means is in the form of a screw engaging said plates.

3. The end fitting as defined in claim 1, wherein said spacing means is constituted by a resilient block, the major cross-section of which is perpendicular to the longitudinal axis.

4. The end fitting as defined in claim 1, wherein facing surfaces of said plates are provided with respective peripheral chamfers, and said spacing means is constituted by an at least partly resilient ring disposed in a space defined and bounded by said groove and said chamfers when said plates are pulled towards each other.

5. The end fitting as defined in claim 4, wherein said ring is a split metallic ring.
