Abstract:
1. An injection hose assembly for connection between an air conditioning or refrigeration system and a manual injector having a fluid containing portion for injecting fluids into the air conditioning or refrigeration system, the assembly comprising: a) a first fitting compatible with a fitting on the system, b) a second fitting compatible with the injector, the second fitting having an opening to which the injector can be connected, c) a substantially non-collapsing joint between the first fitting and the second fitting, d) a generally tubular hose between the first fitting and the joint, and e) an inline normal swivel providing fluid communication between the hose and the first fitting such that the hose has a first conduit fluid path and the first fitting has a second conduit fluid path, and the first conduit fluid path is normal to the second conduit fluid path, and the inline normal swivel permits relative rotation of the hose about the first conduit fluid path and relative rotation of the first fitting about the first conduit fluid path, wherein the first fitting, hose, joint and second fitting are connected to provide fluid connection between the first fitting and the second fitting, wherein the second fitting is offset from the hose and the joint permits at least two positions of the second fitting with respect to the hose when connected to the fluid containing portion of the injector, in the first position the second fitting opening is substantially aligned with the hose directed towards the first fitting and in the second position the second fitting opening is directed at 90 degrees to the hose, and the second fitting is offset from the hose by a distance sufficient to permit the hose and the injector to pass one another without bending the hose.
