Le dispositif possède une coque inférieure (8) avec un bord (9) pourvu d'écornures (10), et ledit bord (9) est situé sur la circonférence de la coque (8). Le dispositif possède également une coque supérieure (11) avec un bord (12) pourvu d'encoches (13), et ledit bord (12) est situé sur la circonférence de la coque (11). Chaque soupape à clapet inverse, de la même manière que la soupape à clapet inverse (4) comporte un logement (46) avec un cadre (47) et une nervure (48) située sur la partie de la circonférence du cadre. Ladite soupape à clapet inverse comporte des fenêtres (49 et 49') munies de réductions (50 et 50'), ainsi qu'une paroi interne (52) et une paroi externe (57). Les parois sont sous la forme de triangles. La soupape à clapet inverse comporte un clapet (59) pourvu d'un rouleau (60) avec une bague (61) et d'un disque séparable (63) pourvu d'un poussoir (64) et d'une bague (65). Le poussoir (64) est relié à un coulisseau (66) par l'intermédiaire d'une barre de poussée (67), le coulisseau (66) étant en outre relié à un actionneur linéaire (69) par l'intermédiaire d'un ressort (68). La coque inférieure (8) comporte une douille (14) destinée à un silencieux acoustique (15) et lesdites douilles contiennent une partie inférieure (15') d'un ventilateur (16). La coque comporte une douille (17) destinée à un silencieux acoustique (18) et des douilles (22 et 22') pour les unités inverses (5 et 5'). Les unités comportent des évidements d'étanchéité (28 et 28'). La coque inférieure (8) comporte une cavité (23) avec une douille (25) pour la séparation horizontale (7) et une cavité (26) avec une douille (25') pour la séparation horizontale (T) et elle comporte également des douilles (19 et 19') pour les blocs régénérateurs (1 et 1'). Lesdites douilles comportent des évidements (27 et 27') pour les joints d'étanchéité (3 et 3'), la coque comportant en outre une séparation verticale (20) avec un bord (21).
