Abstract (en)
Invention relates to a rotary piston pump comprising a housing (1, 2) with inlet and outlet orifices for the pumped fluid, inside the spherical piston chamber the two rotor halves (9, 10) of the rotary piston are connected together by a universal-joint spider, where rotation axes of said rotor halves are at an angle in relation to each other and where the universal-joint spider is included in the disk element (13) between the rotor halves (9, 10). The spider arms (15) of the universal-joint are formed by semi-axles (18), which are connected to the spherical part in the centre of the disk element (13).
