Abstract (en)
Disclosed is a scroll fluid machine wherein a scroll unit achieves higher performance while maintaining reliability. The disclosed scroll fluid machine is provided with: a first actuation chamber (100) and second actuation chamber (102) partitioned by the central end (98) of a wrap (48, 64) of a fixed scroll (44, 60) and the central end (96) of a wrap (46, 62) of a movable scroll (42, 58); and a connection path (106, 119, 112). When at least part of a connection hole (52, 72) gets blocked by the central end of the wrap of the movable scroll as the movable scroll moves in a circle, the connection path connects the first and second actuation chambers with the connection hole. When the central ends of the wraps of the fixed and movable scrolls abut against each other, the connection path cuts off the connection between the first and second actuation chambers and the connection hole.
