Abstract (en)
[origin: EP0146931A2] This comprises an injector 1 and a support portion 2. Injector 1 includes a pressure buffer tube 6 for containing adhesive, a tubular coupler member 9 on the end(s) of tube 6, and a check valve 10 between the end(s) of tube 6 and coupler 9. Support portion 2 includes a base member 3 for location on the crack and a tubular coupler projection 4 on which coupler 9 is to be fitted, so that check valve 10 is pressed open. Thus the adhesive in tube 6 is filled into the crack by gradual and continuous contraction of tube 6. Further adhesive can be provided to tube 6 via the coupler 9 and valve 10 at the other end of tube 6. <IMAGE>
