<p><P>PROBLEM TO BE SOLVED: To provide a fuel pressurizing feeder, whereby an engine for a model can stably pressurize and feed fuel over a low-speed to high-speed rotation. <P>SOLUTION: A fuel valve 8 is controlled by a diaphragm 7 operated on receiving positive pressure in a crank chamber to feed fuel. Only the positive pressure of the pressure in the crank chamber is applied through a reed valve 2b to a fuel tank. The crank chamber is communicated with the outside air through a reed valve 2a to be opened when the interior of the crank chamber becomes negative pressure. The reed valve 2a is provided with a pore 2c, whereby the pressure in the crank chamber is prevented from being increased to excess. On the other hand, the pressurization chamber for applying pressure to the diaphragm 7 is communicated with the outside air through the pore 2a and a slit 5c to enable slow leak. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
