AIR SUPPLY DEVICE FOR VEHICLES

摘要

An air supply device for a vehicle is provided to bend a diffuser passage and install a volute at the upper portion of the diffuser passage, so that the length of the diffuser passage is sufficiently ensured to raise pressure switching performance. An air supply device includes a motor part(140), a motor housing(130), an input duct(110), a bearing holder(120), an impeller(170), an output duct(160), and an end plate(180). The motor part is inserted into the central portion of the motor housing to rotate a rotary shaft(141). The motor part includes a magnet and a stator(145). The stator is spaced apart from the rotary shaft at a predetermined distance. The rotary shaft rotates if electric current is applied to the stator.
