PURPOSE: To remove bubbles generated in a pressure chamber, thus preventing a nozzle from blocking by forming an air discharge hole in the fuel pressure chamber of a fuel pressure adjuster. CONSTITUTION: A fuel pressure adjuster 13 is fastened to the outer side of an upper half portion of a throttle valve. Here, the fuel pressure adjustor 13 has a small hole 131 formed in its pressure chamber, whereby bubbles generated due to high temperature or local low pressure or the air sucked into a fuel tank can be removed from the pressure chamber. As a consequence, a nozzle can be prevented from blocking due to the bubbles. Further, since a fuel pressure and a fuel quantity supplied by a fuel pump are sufficient great, the small hole 131 does not exert influence on the stability of the fuel pressure in the pressure chamber. |
