。 A housing having a fluid suction port and a fluid discharge port, a first side plate fixedly disposed within the housing, and a first spiral body formed on one surface of the first side plate; A first side plate divides the inside of the housing into a suction chamber that communicates with the suction port and a crank chamber in which the first spiral body is present. a fixed scroll member formed with a suction hole communicating with the movable scroll member, a movable scroll member comprising a second side plate and a second spiral body formed on one surface of the second side plate; interlockingly overlapping the second spiral coils such that the side walls of both spiral coils contact each other to form a plurality of line contacts and form at least one pair of closed fluid pockets between the spiral coils; A drive mechanism connected to the movable scroll member causes the movable scroll member to move in a circular orbit, and a rotational movement of the movable scroll member is prevented by a rotation prevention mechanism, so that the fluid pocket is spirally moved by the circular orbit motion. In the positive displacement fluid compression device that moves toward the center of the body and performs a unidirectional fluid compression action with a reduction in volume, the suction hole is located at the outermost part of the first spiral body. The housing inner wall surface of the first spiral wound body outer wall surface is formed at a position offset by approximately 180 degrees from the end and at a position facing a region between the housing inner wall surface and the first spiral wound body outer wall surface. a portion facing the inner wall of the housing is formed by an arc concentric with the inner wall surface of the housing, and the suction hole is a long hole extending along the outer wall surface of the first spiral body. Fluid compression device.
