Abstract

La présente invention est relative à un ensemble de chambre de combustion comprenant un carter annulaire externe (3) de chambre de combustion et une chambre de combustion également annulaire qui est agencée à l'intérieur dudit carter (3), avec des moyens disposés azimutalement de fixation d'une paroi (11) de ladite chambre de combustion (1) audit carter (3), ces moyens de fixation comprenant chacun un pion de fixation (4), ledit carter (3) comportant des orifices d'insertion (300), tandis que ladite paroi (11) de la chambre de combustion (1) comporte des orifices de réception (15) en regard desdits orifices d'insertion (300), chaque pion (4) étant inséré dans un orifice d'insertion (300) et dans l'orifice de réception (15) disposé en regard, ledit pion (4) ayant un corps en forme de fût (41) généralement cylindrique, tandis que ledit orifice de réception (15) correspondant a la forme d'une cheminée, caractérisé par le fait que ledit fût (41) : - est inséré dans un fourreau (5) fixé audit carter (3); - est seulement en contact avec ce fourreau (5) ; - et est monté mobile en rotation autour de son axe longitudinal (X-X'), relativement audit fourreau (5). Figure pour l’abrégé : figure 5The present invention relates to a combustion chamber assembly comprising an outer annular casing (3) of the combustion chamber and an equally annular combustion chamber which is arranged inside said casing (3), with means arranged azimuthally fixing a wall (11) of said combustion chamber (1) to said casing (3), these fixing means each comprising a fixing pin (4), said casing (3) comprising insertion orifices (300) , while said wall (11) of the combustion chamber (1) comprises receiving orifices (15) facing said insertion orifices (300), each pin (4) being inserted into an insertion orifice (300 ) and in the receiving orifice (15) arranged opposite, said pin (4) having a barrel-shaped body (41) generally cylindrical, while said receiving orifice (15) corresponding to the shape of a chimney , characterized in that said drum (41): - is inserted into a sheath (5) fixed to crankcase audit (3); - Is only in contact with this sheath (5); - And is rotatably mounted around its longitudinal axis (X-X'), relative to said sheath (5).
