摘要： The invention relates to a rotary piston machine, comprising a housing (10) and a piston (12) which is situated in a hollow area of the housing (10) in such a way that it can rotate and which is rotationally fixed to a shaft (18) that passes through the housing (10). At least one inlet channel and at least one outlet channel for guiding a working fluid in or out of the hollow area are configured in the housing (10). According to the invention, the hollow area has a section which is configured in the form of a cylindrical ring cavity that is coaxial to the shaft (18). The piston (12), as a ring piston, is configured in the form of a cylindrical tubular section which engages in the ring cavity of the housing (10) and is axially displaceably guided in said ring cavity. The end surfaces (20,26) of the ring cavity and the ring piston (12) facing away towards each other are configured as constant wavy surfaces with an axially parallel amplitude. The inlet and outlet openings are located within an axial area of the lateral surface of the ring cavity that is determined by the maximum axial interval of the wave hollows of the end surfaces (20,26) facing towards each other.

摘要： The invention relates to a rotary piston pump comprising a housing (10), an annular piston (18) in the form of a tubular segment, which is connected to a shaft (22) in a rotationally fixed manner and which is guided rotationally and displaceably in an annular chamber (28, 10) of the housing, said chamber being coaxial with the shaft (22). The rotary piston pump also comprises at least one inlet and one outlet which are configured in the housing in such a way that the inlet or outlet on the annular chamber side are located inside an axial area of a surface area of the annular chamber, said surface area being determined by the maximum axial distance of the wave troughs of the end surfaces that face each other. The invention is characterized in that the annular piston has control pockets which are open toward its axial end surface, said control pockets controlling the inlets and outlets, wherein the characteristics of the control pockets (38) and the inlets and outlets are selected in such a way that maximum volume flow of the medium to be conveyed is enabled by the inlet (40) when the piston performs a stroke between the top and bottom dead center and by the outlet (56) when the piston performs a stroke between the bottom and top dead center.
