The fluid flow operated machine has a housing (1) and a rotary shaft (2) formed flowing path. An axial arrangement is selected such that a certain partial length of a recess (4) is extended before a front edge of a shovel (3) against a flow direction. The radial depth of the recess amounts to a certain percentage of an axial cord length of the shovel. An inclination angle of a rear surface in circumferential direction amounts to 30 degrees to 60 degrees.
