Title: Pressure reducing regulating valve of fuel injection system
Inventor: GOTO MORIYASU
IPC: F02D41/38
Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a pressure reducing regulating valve having both the function as a pressure reducing valve and the function as a safety valve at steady operation time and capable of reducing the size and a cost in a commom rail type fuel injection system. SOLUTION: When pressure of a common rail 103 exceeds prescribed pressure at speed reduction time, an electric current is carried to a coil 21 of the pressure reducing regulating valve 1 to open a valve element 41 arranged in a high pressure passage 35 communicated with the common rail 103 to discharge high pressure fuel of the common rail 103 to a low pressure passage 204 reaching a fuel tank via the high pressure passage 35, a low pressure chamber 33 and a low pressure passage 34 to thereby quickly reduce pressure of the common rail 103 to prevent noise. When the pressure of the common rail 103 becomes specified pressure abnormality by some abnormality, the valve element 41 automatically opens against energizing force of a spring 6 to thereby set the pressure of the common rail 103 not more than specified pressure to secure safety.
