Definitions
- the present invention relates to a high-pressure fuel supply device, and more particularly to a high-pressure fuel supply device for supplying high-pressure fuel to an internal combustion engine.
- a fuel supply system for a fuel injection type automobile internal combustion engine is generally as shown in FIG. 3, in which fuel 2 in a fuel tank 1 is delivered from a fuel tank 1 by a low-pressure pump 3. After passing through the filter 4 and being regulated by the low-pressure regulator 5, it is supplied to the high-pressure fuel supply device 6, which is a high-pressure pump. The fuel is supplied to the common rail 9 of the internal combustion engine (not shown) after the fuel is increased in pressure only by the flow rate required for fuel injection by the fuel supply device 6. Excess fuel is relieved from the solenoid valve 17 between the low-pressure damper 12 and the suction valve 13. The required flow rate is determined by a control unit (not shown) and controls the solenoid valve 17.
- the high-pressure fuel thus supplied is injected into a cylinder (not shown) of the internal combustion engine as a high-pressure mist from the fuel injection valve 10 connected to the common rail 9.
- the fill valve 7 and the high-pressure relief valve 8 are opened when the internal pressure of the common rail 9 becomes abnormal pressure (high-pressure relief valve opening pressure) to prevent the common rail 9 and the fuel injection valve 10 from being damaged.
- the high-pressure fuel supply device 6 which is a high-pressure pump, pressurizes the fuel supplied through a filter 11 that filters the supplied fuel, a low-pressure damper 12 that absorbs the pulsation of the low-pressure fuel, and a suction valve 13. And a pump 16 for discharging high-pressure fuel through a discharge valve 14 and a fuel pressure holding valve 15.
- the fuel pressurizing chamber 24 composed of the plunger 26, the sleeve 25, the plate 102, the suction valve 13 and the discharge valve 14 of the pump 16 has an electromagnetic valve 17 Through the low pressure damper 12 and the suction valve 13.

That is, a cylinder 25 is provided. A plunger 26 is provided in the cylinder 25 so as to be slidable in the axial direction so that the volume of the pressurizing chamber 24 in the cylinder 25 is variable. A compression spring 27 is provided at the inner end (the upper end in the figure), and the outer end (the engine camshaft not shown in the figure below) receives a driving force from the outside and transmits the driving force to the plunger 26. The working member, which is the evening pet 28, is fitted and fixed in this way. The plunger 26 and the evening pet 28 constitute the piston 89 of the high-pressure fuel supply device 6.
- the high-pressure fuel supply device 6 integrally includes a pump 16 as a plunger pump, an electromagnetic valve 17 connected to a pressurizing chamber 24, and a low-pressure damper 12.
- the high-pressure fuel supply device 6 also includes a casing 30 substantially surrounding the cylinder 25 and the piston 29 to prevent fuel leaking from between the cylinder 25 and the piston 29 from leaking outside. It is provided with a rubber sealing device 31 for sealing a gap between the single 30 and the plunger 26 of the piston 29.
- a plunger piston 29 is driven up and down in FIG. 4 by a driving force provided coaxially with an engine camshaft (not shown) to suck and discharge fuel.
- the high-pressure fuel in the pressurizing chamber 24 is released (released) to the low-pressure suction side by opening the solenoid valve 17 and then into the common rail 9. No more fuel is pumped.
- the valve opening timing of the solenoid valve 17 the discharge amount from the fuel supply device 6 is variably adjusted and controlled.
- the sealing device 31 for preventing the fuel in the high-pressure fuel supply device 6 from leaking into the engine room is provided as a shaft-side member for pressurizing the fuel.

- an oil film is formed on the seal part where the plunger 26 that draws in fuel or engine oil during reciprocation of the piston 29 and the lip part of the rubber seal device 31 Not to wear I have to.
- Such a structure is not a perfect seal, but a structure that accepts and uses a certain small amount of leakage. Therefore, the surface condition of the shaft side at the seal part, the moving speed of the shaft, and the rubber loop There is a problem that the lubrication state of the seal portion changes greatly depending on the shape, interference, and the condition of the fuel and engine oil around the lip, causing wear on the seal portion and increasing the amount of leakage.
- the piston 29 for pressurizing the fuel is the most important component, and it takes a lot of time for evaluation.
- wear and seizure of the sleeve 25 that constitutes the fuel pressurization chamber 24 like the piston 25 and fits with a certain gap with the piston 29 becomes a problem. If such a problem occurs in the seal portion in such a conventional device, it is necessary to simultaneously evaluate the effect of the Biston 29 on the wear and seizure of the slip 25, and the evaluation time Requires a lot of time. In addition, more time is required for evaluation because restrictions are imposed on measures for the piston 29 side.
