Формула изобретени  1. ВЕНТИЛЯТОР, содержащий корпус с входным и выходным отверсти ми и лопат- ки, размещенные в корпусе на несущем диске и спицах, установленных на валу, отличающийс  тем, что, с целью повышени  напора и производительности, кажда  лопатка изогнута в продольном направлении, причем изогнуты/5 участки расположены под углом друг к другу и имеют суммарную длину больше продольной длины корпуса.SUMMARY OF THE INVENTION 1. A FAN comprising a housing with inlet and outlet openings and vanes arranged in a housing on a carrier disk and spokes mounted on a shaft, characterized in that, in order to increase the pressure and productivity, each blade is curved in the longitudinal direction moreover, bent / 5 sections are located at an angle to each other and have a total length greater than the longitudinal length of the housing. 2. Вентил тор по n.f. отличающийс  тем, что дополнительно содержит изогнутые в продольном направлении лопасти, один конец каждой из которых соединен с наружной поверхностью лопатки со стороны входного отверсти , а другой конец размещен во входном отверстии, причем изогнутые участки лопатки расположены под углом друг к другу.2. Fan according to n.f. characterized in that it further comprises longitudinally curved blades, one end of each of which is connected to the outer surface of the blade from the inlet side, and the other end is placed in the inlet, the curved portions of the blade being angled to each other.
