ABSTRACT:
A blower comprising: a vane wheel including a pair of grooves, and blades extending in a radial direction of the vane wheel in each groove, and a casing including stationary flow paths facing to the grooves respectively so that the gas urged in the grooves is capable of flowing in a circumferential direction in the stationary flow paths, a guide flow path extending in the axial directions to fluidly communicate with both of the stationary flow paths to enable the gas to flow from one of the stationary flow paths to the other one of the stationary flow paths, an inlet port for introducing the gas into the one of the stationary flow paths facing to the one of the grooves and an outlet port for discharging the gas out of the other one of the stationary flow paths facing to the other one of the grooves.
