ROTARY COMPRESSOR AND REFRIGERATION APPARATUS

A compressor includes a cylinder (101); a cylinder chamber (103); a piston turning along an inner peripheral surface (101a) of the cylinder (101); a blade that partitions the cylinder chamber (103) into a high pressure side region and a low pressure side region together with the piston; a blade hole...

More Information
Summary:A compressor includes a cylinder (101); a cylinder chamber (103); a piston turning along an inner peripheral surface (101a) of the cylinder (101); a blade that partitions the cylinder chamber (103) into a high pressure side region and a low pressure side region together with the piston; a blade hole (104) allowing the blade to advance and retract; a suction passage (120) that extends from an outer peripheral surface of the cylinder (101) to the inner peripheral surface (101a) of the cylinder (101) and guides a refrigerant to the cylinder chamber (103); and a pipe connection member (200) having a press-fitting portion (201b) press-fitted into the suction passage (120) from a radially outer side of the cylinder (101). A distance (R2) from a center point (O1) of the cylinder chamber (103) to the press-fitting portion (201b) is equal to or longer than a distance (R1) to a radially outer end of the blade hole (104).
