    • The invention relates to a pump comprising a pump chamber (1); a suction duct (2) which leads into the pump chamber; a discharge duct (3) which leads out of the pump chamber; in the pump chamber a rotor (4) having a shaft (5) in which the cross-sectional profile of the outer surface is a circular arch, and a spiral flange (6) supported on the shaft; and, parallel to the shaft of the rotor and following the shape of the circular outer surface thereof, a disk (7) that is arranged to rotate in a narrow disk chamber (8) opening into the pump chamber, and is provided with a slot (9) for the spiral flange. In accordance with the invention, the inner surface of the pump chamber (1) is spherical; the periphery of the spiral flange (6) corresponds by shape to the spherical surface, resting tightly against it; the spiral flange makes a full revolution around the shaft (5); and the disk comprises, at intervals of 90°, four radial slots (9) through which the spiral flange is able to slide, so that, as the rotor rotates 360°, the disk will rotate 90°.
    • 本发明涉及一种包括泵室(1)的泵; 一个通向泵室的吸入管道(2) 排出导管(3),其从泵室导出; 在所述泵室中具有转子(4)和螺旋凸缘(6),所述转子(4)具有其中所述外表面的横截面轮廓为圆弧的轴(5)和支撑在所述轴上的螺旋凸缘(6) 并且平行于转子的轴并且遵循其圆形外表面的形状,盘(7)被布置成在开口到泵室中的窄盘室(8)中旋转,并且设置有狭槽 (9)用于螺旋法兰。 根据本发明,泵室(1)的内表面是球形的; 螺旋凸缘(6)的周边在形状上对应于球形表面,紧贴在其上; 螺旋凸缘围绕轴(5)完整旋转; 并且盘以90°的间隔包括四个径向槽(9),螺旋凸缘能够通过该径向槽滑动,从而当转子旋转360°时,盘将旋转90°。
