Abstract
Each of recesses in outer circumferential surfaces of rotors includes: a leading-side area extending forward from a longitudinal center of an associated one of the outer circumferential surfaces in a rotation direction of the rotor, and a trailing-side area continuous with the leading-side area, and extending rearward from the longitudinal center in the rotation direction. From the longitudinal center of the associated one of the outer circumferential surfaces in the rotation direction, forward extension of the leading-side area is longer than rearward extension of the trailing-side area. The leading-side area has a larger volume than the trailing-side area.
