ロール型流体機械。 By interlocking a fixed scroll and an orbiting scroll, each having a spiral wrap erected on its end plate, a pair of sealed scrolls whose volume changes according to the orbiting movement of the orbiting scroll are provided between the two scrolls. A discharge port is formed in the center of the end plate of one of the two scrolls, and when one of the closed chambers and the discharge port communicate with the end plate of the other scroll, a discharge port is formed in the center of the end plate of one of the scrolls. A scroll-type fluid machine comprising a concave pocket that communicates a closed chamber with the discharge port to balance the pressure between the pair of closed chambers, characterized in that the corner portion of the concave pocket is formed with a smooth curve. Scroll type fluid machine.
