In order to provide a displacement type fluid machine for reducing a fluid loss of a discharge process as much as that of a scroll fluid machine, easily prepared than the scroll fluid machine, in the displacement type fluid machine wherein a shaft is gyrated in a hollow cylinder whose section shape comprises a series of curves so that a working fluid is discharged from a plurality of discharge ports, a shaft angle thetac of a compression process of each working chamber is given by the following algorithm:(where, N is the number of threads).
