Constitutive element part provides purely self-sufficient pressure regulation, not only achieves pressure by the Function Coupling of valve Yu variable restrictor portion and declines
Regulation, and realize pump according to the suction of the pressure from high-pressure area throttling, energy requirement that fuel sprays and the most whole
The fuel consumption of system diminishes owing to lacking electricity parts.
Foregoing invention patent solves some problems, but is designed with certain defect, joint in the internal duct of restriction
It is one-body molded that the design of stream portion interior groove is on steel construction, bad maintains whole device, and whole oil circuit is narrower, if
Impurity is blended in fuel oil, easily makes the oil circuit in whole oil burning installation block, and the oil circuit after blocking has a strong impact on spray below
Oil process, also can affect the dynamic property of automobile.
Summary of the invention
The invention is intended to provide a kind of fuel oil with spring vibration device to regulate pump, to solve, oil circuit appearance is susceptible to plugging asks
Topic.
In order to achieve the above object, the base case of the present invention is as follows: a kind of fuel oil with spring vibration device regulates
Pump, including fuel oil regulation pump, restriction, pump oil pipe and oil return pipe, described oil return pipe one end is fixing connects restriction, and oil return pipe is another
One end is fixing connects fuel oil regulation pump, and described restriction is divided into low-pressure area, suction district and slip in low-pressure area and suction district
Regulation valve, one end of described regulation valve is arranged in suction district, and the other end of regulation valve is arranged in low-pressure area, described suction district
Inside being provided with accumulator, oil outlet, spill port, oil-recovery tank, oil-feed tank and pouring orifice, described fuel oil regulation pump is by pump oil pipe and joint
The pouring orifice at top, stream portion is fixing to be connected, and described oil-feed tank, oil-recovery tank, spill port connect formation respectively with oil outlet with accumulator
