Inventor: YAMAMOTO KAZUO
IPC: F02M69/00
Filed: 1992-03-05
Abstract: PURPOSE:To prevent the collision of a valve with a valve seat due to the pulsation of the compressed air. CONSTITUTION:In a fuel injection device for facilitating fuel atomization by mixing fuel with the compressed air, an air chamber 2 in an air pressure control valve 33 for regulating the pressure of the compressed air at the predetermined level is divided into chambers 2a and 2b with a dividing member 3. An orifice 4 for throttling an air flow area is formed on the member 3. The compressed air from an air compressor 29 flows into the chamber 2b, while pulsating due to pressure fluctuation in the compressor 29 and pressure fluctuation at the time of air injection, but is throttled with the orifice 4. The pulsation of the air flowing into the chamber 2a is thereby reduced. Consequently, the hunting of a valve 22 due to the pulsation and the repeated collision thereof with a valve seat 19 can be prevented. According to this construction, stable air pressure control can be ensured and furthermore, the durability of the valve 22 and valve seat 19 can be improved.
