Abstract

Invention relates to a rotary piston pump comprising a housing with inlet and outlet openings for a pumped fluid, inside the spherical piston chamber two rotor halves of the rotary piston connected together by a universal joint spider, where the axis of rotation of said rotor halves are at an angle in relation to each other and where the universal joint spider is located within the disk element between rotor halves. Arms of the spider of the universal joint are formed by half spindles, which are connected to the spherical part in the centre of a disk element.
