<p>An orbital device in which the orbiting outer member of a gerotor set is restrained from rotation but allowed to orbit about a plurality of circumferentially spaced bolts extending through a chamber in a housing by coaction between a like plurality of outwardly opening axially elongated grooves at the periphery of the outer member, the grooves being dimensioned to directly engage the bolts so as to restrict movement of the outer member to an orbital motion, the bolts being positioned inwardly of the axially extendant outer wall of the housing and the grooves in the outer member of the gerotor set being disposed radially outwardly of the crests of the internal teeth on the outer member.</p> |
