A cylinder assembly of a compressor includes: a cylinder (110) having a cylindrical inner space (W) partitioned into a first space and a second space as partition plate (30) of a rotational shaft (21) is inserted thereinto and a step insertion portion (116) formed at both sides thereof in a ring shape; a first bearing (160) having the rotational shaft (21) coupled at a central portion and being inserted to be coupled into the step insertion portion (116) formed at one side of the cylinder (110) so as to cover the inner space of the cylinder; and a second bearing (170) having the rotational shaft (21) coupled at the central portion thereof and being inserted to be coupled into the step insertion portion (116) formed at the other side of the cylinder so as to cover the inner space of the cylinder (110). A dead volume is reduced and thus a re-expansion loss of a refrigerant gas can be reduced.

L'invention concerne un ensemble cylindre de compresseur comprenant un cylindre (110) ayant un espace interne cylindrique (W) divisé en un premier espace et en un second espace sous forme de plaque de séparation (30) d'une tige rotative (21) insérée ainsi qu'une partie d'insertion (116) formée sur les deux côtés sous forme annulaire; un premier roulement (160) ayant la tige rotative (21) couplée au niveau de la partie centrale et insérée de manière à être accouplée dans la partie d'insertion (116) formée sur un côté du cylindre (110) de manière à recouvrir l'espace intérieur du cylindre; ainsi qu'un second roulement (170) ayant la tige rotative (21) couplée au niveau de la partie centrale et insérée de manière à être accouplée dans la partie d'insertion (116) formée sur l'autre côté du cylindre de manière à recouvrir l'espace intérieur du cylindre (110). Un volume mort est réduit ce qui entraîne la réduction de la perte de ré-expansion d'un gaz de refroidissement.
