Abstract

Настоящее изобретение относится к крыльчатке (12) центробежного или полуосевого типа, используемой в насосе для насосной подачи жидкостей и выполненной с одной или несколькими лопастями (18) таким образом, что лопасти прикреплены к закрывающим дискам (12, 16) на каждой стороне, образуя так называемую закрытую крыльчатку, характеризующейся тем, что передние края (40) лопастей изогнуты назад во входное отверстие (42) одного из закрывающих дисков (12) крыльчатки.
