The invention relates to an oscillating slide machine working on an eccentric circulatory motion, whereby the oscillation guide grooves ( 19 ) on the inner rotor ( 5 ) are provided with groove front edges ( 20 ) and groove rear edges ( 21 ) of differing heights, such that the diameter of the imaginary circle ( 17 ), connecting all groove front edges ( 20 ), is smaller than the diameter of the circle connecting all the groove rear edges ( 21 ).
