A compressed gas is introduced from a compressor into an inlet 2aa of a check valve 1 and discharged through an outlet 3a from the check valve 1. A ball valve 5 is disposed on a valve receiver 6 between the inlet 2aa and the outlet 3a in the check valve 1. The ball valve 5 is more strongly pressed onto the valve receiver 6 in an upstream side than in a down-stream side to prevent back flow of the gas.

| 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 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. | ||||||
