A rotary compressor comprising a cylinder (5) having a cylinder chamber (51) having a suction hole (52) and an exhaust hole (53) both formed therein, a roller (7) adapted to fit over an eccentric shaft portion (31) of a driving shaft (3) and to be installed in the cylinder chamber (51), and a blade (9) dividing the interior of the cylinder chamber (51) into a low pressure chamber (X) communicating with a suction port (54) and a high pressure chamber (Y) communicating with an exhaust port (55), wherein the suction hole (52) is formed in the internal circumferential surface of the cylinder chamber (51) in such a manner as to be inclined towards the blade (9) relative to a normal (c) perpendicular to a tengent (b) at the portion where the suction hole (52) is formed. Due to this configuration, the flow resistance caused when gas fluid is sucked from the suction hole (52) into the low pressure chamber (X) of the cylinder chamber (51) is made small, whereby pressure loss in the low pressure chamber (X) of the suction gas can be reduced. <IMAGE> |
