Abstract

Provided is a scroll fluidic device that is capable of reducing suction pressure loss as well as suppressing discharge pulsations and reducing noise. The scroll fluidic device is characterized in that a fixed scroll member is integrally formed with a center housing on the inside of the center housing disposed between a front housing and a rear housing; the end surface of the outer shell of the center housing is positioned lower than the height of a scroll lap of the fixed scroll member, with an end plate of the fixed scroll member served as a reference of position in the height direction; and a corridor-like space extending in the device circumferential direction, which is surrounded by an outer shell forming portion of the center housing, the inner surface of an outer shell of the front housing, the scroll lap of the fixed scroll member, and the end plate of a movable scroll member, is formed.
