Abstract
A fluid machine includes a stationary scroll member and a movable scroll member. A second tooth portion of the movable scroll member is arranged to be revolved with respect to a first tooth portion of the stationary scroll member and to form an operating chamber between the movable scroll member and the stationary scroll member. The operating chamber is changeable in accordance with a revolution of the movable scroll member to be defined between two sliding contact portions, and is dividable into first and second operating chambers. The second tooth portion is provided with a passage portion through which an introducing port for introducing a fluid to the operating chamber communicates with the second operating chamber when the introducing port communicates with the first operating chamber. The passage portion disconnects the introducing port from the second operating chamber when the introducing port is disconnected from the first operating chamber.
