<p><P>PROBLEM TO BE SOLVED: To provide a scroll part structure and a supercharger capable of reducing pumping loss, increasing a turbine output, and suppressing load concentration to a rotor vane. <P>SOLUTION: A scroll flow channel 32 are divided so as to correspond to cylinders 21 to 24 in one to one correspondence and to be arranged in parallel about a rotary shaft. The scroll flow channel 32 includes a distal end side scroll flow channel 32a for feeding a fluid to a distal end side of the rotor vane 31 and a root side scroll flow channel 32b for feeding the fluid to the root side of the rotor vane 31. In accordance with the exhaust order of the cylinders 21 to 24, the scroll flow channel 32 is connected to the cylinders 21 to 24 so as to include portions for feeding the fluid to the root side scroll flow channel 32b after feeding the fluid to the distal end side scroll flow channel 32a, and for feeding the fluid to the distal end side scroll flow channel 32a after feeding the fluid to the root side scroll flow channel 32b. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
