Abstract (en)
[origin: EP0580547A1] For injection devices for two-component materials, a nozzle is provided within which the mixing of the individual components takes place. The nozzle has a mixing tube (1) for a first discharge opening (3a) and, arranged coaxially therewith, a tube piece (2) for a second discharge opening (3b) of the injection device. The pipe piece (2) is provided with a non-return valve which comprises passages (2b) of the pipe piece (2) and a sleeve (5) surrounding this region of the pipe piece (2). This non-return valve prevents a back-surge of the individual components and promotes the formation of a closure by a portion of cured components, so that even during actuation of the injection device with the nozzle, with cured components accumulated thereon, still mounted, no back-surge into the injection device occurs. <IMAGE>
