Det tryck, som erhålles inuti innerröret vid gasens explosion bestänunes av gasens salumarasättluirxg, tryck och tenperatur före explosionen. Trycket kan också påverkas genom inblandning av andra gaser såsom kväve, koldioxid m fl.The pressure obtained inside the inner tube during the gas explosion is determined by gas salumarasättluirxg, pressure and temperature before the explosion. The pressure can also affected by the admixture of other gases such as nitrogen, carbon dioxide, etc.

Expansionen av irmerröret underlättas om spalten 1' mellan :inner- och ytter- rör evakueras från luft Lmder, såsom före explosionen, förloppet. Detta kan ske exempelvis medelst ett hål 1" gencm det yttre röret 1, fig. 1, Vilket hål förbinder spalten 1' med det yttre rörets utsida., där spalten evakueras exempelvis via en nippel 1"' och en, ej visad, vacnurrpuxrp. För att erhålla en kontrollerad och reproduoerbar expansion, bör gasmängder och tryck styras av en automatik 11, bestående av t ex magnetventiler och elektronik med tidsfunktion. Enligt ett föredraget utförande är den explosiva gasens erxergiirmeliåll avsett att avpassas så att det inre röret plastiskt deformeras och så att det yttre »röret enclast elastiskt defomeras.The expansion of the inner tube is facilitated if the gap 1 'between: inner and outer pipes are evacuated from air Lmder, as before the explosion, the course. This can be made, for example, by means of a hole 1 "through the outer tube 1, Fig. 1, Which hole connects the gap 1 'to the outside of the outer tube, where the gap is evacuated, for example, via a nipple 1 "'and a, not shown, vacnurrpuxrp. to obtain a controlled and reproducible expansion, gas volumes should and pressure is controlled by an automatics 11, consisting of eg solenoid valves and electronics with time function. According to a preferred embodiment, it is explosive the gas exchanger is intended to be adapted so that the inner tube is plastic deformed and so that the outer tube is elastically deformed.

Före införandet av den explosiva gasen evakueras luften genom en ventil- försedd ledning 12. Alternativt lämnas denna öppen under början av gasens nßttmmirzg' " ' och stang" es uzrzan' gastrycket ökas' . Detta förfarande anvand" es då luften användes som oxiderarxíle gas.Prior to the introduction of the explosive gas, the air is evacuated through a valve provided line 12. Alternatively, leave it open at the beginning of the gas nßttmmirzg '"' and rod" es uzrzan 'gas pressure increases'. This procedure is used when the air was used as oxidizing gas.

Efter explosionen avlastas 'trycket genom en avloppslednzirag 13, varefter gav- larna borttages.After the explosion, the pressure is relieved through a drain line 13, after which the the larvae are removed.

I löpanie produktion är lämpligen den gavel, genom vilken tillförseln av gasen sker, fast monterad och mtståenie gavel axiellt rörlig, till exempel neaeiet , ej visad, hyareulik.In runner production is suitably the gable through which the supply of the gas occurs, fixedly mounted and mtståenie end axially movable, for example neaeiet, ej visad, hyareulik.
