Abstract

"CONJUNTO DE CILINDRO DE COMPRESSOR". Um conjunto de cilindro de um compressor inclui: um cilindro (110) tendo um espaço (W) interno cilíndrico dividido em um primeiro espaço e em um segundo espaço quando chapa (30) divisória de um eixo (21) rotacional é inserida no mesmo, e uma parte (116) de inserção de degrau formada em ambos os seus lados em um formato anular; um primeiro mancal (160) tendo o eixo (21) rotacional acoplado em uma parte central e sendo inserido para ser acoplado na parte (116) de inserção de degrau formada em um lado do cilindro (110) de modo a cobrir o espaço interno do cilindro; e um segundo mancal (170) tendo o eixo (21) rotacional acoplado na sua parte central e sendo inserido para ser acoplado na parte (116) de inserção de degrau formada no outro lado do cilindro de modo a cobrir o espaço interno do cilindro (110). Um volume morto é reduzido e dessa forma uma perda de re-expansão de um gás refrigerante pode ser reduzida."COMPRESSOR CYLINDER SET". A cylinder assembly of a compressor includes: a cylinder (110) having a cylindrical inner space (W) divided into a first space and a second space when a divider plate (30) of a rotational shaft (21) is inserted therein, and a step insert portion (116) formed on both sides thereof in an annular shape; a first bearing (160) having the rotational shaft (21) coupled to a central portion and being inserted to be coupled to the step insert portion (116) formed on one side of the cylinder (110) to cover the internal space of the cylinder; and a second bearing (170) having the rotational shaft (21) coupled to its central part and being inserted to be coupled to the step insert portion (116) formed on the other side of the cylinder to cover the internal space of the cylinder ( 110). A dead volume is reduced and thus a loss of re-expansion of a refrigerant gas can be reduced.
