Abstract: In a horizontal type scroll compressor an external end of a volute (2b) of a fixed scroll (2) is extended near to an external end side of a volute (3b) of a movable scroll (3). By the extension of the volute (2b), inlet ports (22, 23) opening to compression rooms (RA, RB) respectively are disposed near to each other and are located at an upper level in a closed casing (1). An inlet passage (24) is formed at the top of a housing (4) which divides the closed casing (1) into a compression element chamber (12A) and a motor chamber (12B). The opening position of an inlet pipe (11) is displaced circumferentially with respect to the inlet passage (24). The inlet passage (24) is displaced circumferentially with respect to the inlet ports (22, 23) of the compression rooms (RA, RB). The inlet passage (24) is displaced forward in a traveling direction of the movable scroll (3) with respect to the inlet ports (22, 23).
