ABSTRACT:
A Roots type blower has two rotors enclosed within a housing and each having alternately and contiguously therearound a plurality of lobes each having an outer profile of a convex arc and recesses each having an inner profile of a concave arc, the lobes of one rotor meshing cyclically in turn with respective recesses in the other rotor as the rotors rotate in opposite direction. The rotors are formed and assembled with their profile in relation to respective pitch circles with such dimensional configuration that the radius of the convex arc of each lobe is smaller than the radius of the concave arc, and that the point of intersection between each convex arc and the concave arc of the adjacent recess of a rotor is positioned outside the pitch circle of that rotor.
