Abstract

According to the present invention, there is provided a scroll type fluid machinery in which a sta-tionary scroll and a revolving scroll in which spiral wraps are set up at end plates, respectively, are engaged with each other, a drive bushing is fitted rotatably into a boss projected at the central part of the outer surface of the end plate of the revolving scroll, and a drive pin projecting from the rotary shaft is fitted slidably into a slide hole bored in the drive bushing, characterized in that a counter weight which generates a centrifugal force having an opposite direction to a centrifugal force acting on the revolving scroll at the time of revolving motion in a solar motion thereof is provided on the drive bushing.
Further, the contact pressure between the wrap of the revolving scroll and the wrapof the stationary scroll is prevented to become excessive even at the time of high speed rotation of the rotary shaft.
