Abstract

Изобретение относится к насосу для перекачивания загрязненной жидкости, включающей твердое вещество, содержащему крыльчатку (1), выполненную с возможностью вращения в насосной камере указанного насоса, причем крыльчатка (1) перемещается в осевом направлении относительно уплотнительной крышки (3) корпуса между первым положением, смежным с гнездом (2) крыльчатки, и вторым положением, отнесенным от указанного гнезда (2) крыльчатки, причем насос также содержит полость (17), ограниченную уплотнительной крышкой (3) корпуса и крыльчаткой (1), и по меньшей мере одно отверстие (20), соединяющее указанную полость и указанную насосную камеру. Кроме того, отверстие (20) имеет первую площадь сечения потока, когда крыльчатка (1) находится в первом положении, и вторую площадь сечения потока, которая больше, чем первая площадь сечения потока, когда крыльчатка (1) отнесена от первого положения.
