Abstract

An injection nozzle having a nozzle body defining an injection cavity and at least one curing device integrally formed within the nozzle body.

Claims

1. An injection nozzle for encapsulating a component in sealant in situ, the injection nozzle having a nozzle body defining an injection cavity and at least one sealant curing device integrally formed within the nozzle body.

2. An injection nozzle according to claim 1 wherein the sealant curing device comprises at least one heating element.

3. An injection nozzle according to claim 1 wherein the sealant curing device comprises at least one light source.

4. An injection nozzle according to claim 3, wherein the light source comprises an LED.

5. An injection nozzle according to claim 3, wherein the light source comprises a fibre optic cable.

6. An injection nozzle according to claim 1, wherein the nozzle body comprises a plurality of movable nozzle portions arranged to be reversibly moved with respect to each other between at least a first configuration in which the injection cavity has a first volume and a second configuration in which the injection cavity has a second different volume.

7. An injection nozzle according to claim 6, wherein the movable nozzle portions comprise a plurality of concentric elements arranged to be linearly transposed with respect to one another along a central axis.

8. An injection nozzle according to claim 6, wherein the movable nozzle portions comprise a plurality of overlapping nozzle leafs arranged to rotatably transposed with respect to one another about a central axis.
