Claims

[Scope of utility model registration request]

′ At the position of the revolution-side spiral body where the contact points of both spiral bodies begin to separate from each other in the closed chamber formed by inward contact with the stationary-side spiral body as the revolution-side spiral body revolves,
A scroll type fluid machine characterized in that a notch is carved in a discharge port to communicate one of two outer small chambers.
