Definitions
- the invention is based on a piston pump according to the Genus of claim 1.
- the piston pump according to the invention with the features of Patent claim 1 has the advantage that the Partial filling of the respective pump element is no longer in the essential of the interaction of the delivery pressure of Feed pump, the spring force of the first check valve and depends on the vacuum generated by the pump piston, but the duration of the filling of the pump element of the im essentially loaded only by delivery pressure and spring force second check valve is determined which at low flow rate of the fuel supplied also the Filling limited while the first check valve in the printing phase of the conveying process only substantially serving to the cylinder space of the pump element against the shut off the second check valve. Of the Fuel metering is thus no longer of the Opening duration of the first check valve determined. beginning and end of the metering process according to the invention from Delivery pressure of the fuel introduced and limited.
- FIG. 1 shows a Hydraulic circuit diagram of part of a Fuel injection system with a piston pump for High-pressure fuel supply system and Figure 2 a Section through a pump element of the piston pump.
- the hydraulic circuit diagram shown in Figure 1 shows a Pump arrangement for high-pressure fuel production for a in Internal combustion engine used fuel injection system, in particular common-rail injection system.
- the Pump arrangement has a low-pressure feed pump 1, which on the suction side, for example, a diesel fuel containing fuel tank 2 is connected. Of the Feed pump 1 is on the pressure side, a delivery line 3, in which a flow control valve 4 is arranged.
- the pump assembly also includes a high pressure piston pump 6 with three pump elements 7 on which, respectively a pump piston 8 in a cylinder chamber 9, a suction side first and second check valves 10 and 11 as well pressure side comprise a pressure valve 12.
- the under one Angular distance of 120 ° arranged pump piston 8 are supported by spring force on a cam ring 13, which of an eccentric shaft 14 is driven.
- the delivery line 3 is after the flow control valve. 4 branches and in each case to the second check valve 11 of the Pump elements 7 connected.
- the two against spring force in the direction of the cylinder chamber 9 opening check valves 10 and 11 are arranged in series, with the first Check valve 10 close to the cylinder in the respective Delivery line branch lies.
- From the pressure valves 12 of the Pump elements 7 go line branches one High-pressure fuel line 15 off, which is not one illustrated high - pressure fuel storage of the Fuel injection system leads.
- the low-pressure feed pump 1 and the high-pressure piston pump 6 are constant pumps.
- In the simplified hydraulic circuit diagram of Figure 1 are no belonging to the pump assembly pressure control and limit valves, return lines and fuel filters shown.
- a pump piston 8 in one Cylinder space 9 of a housing 17.
- To the cylinder chamber 9 is connected to the pressure valve 12 of the pump element 7.
- Of the Cylinder space 9 is characterized by an annular disc-shaped Valve plate 18 completed. This one is through Housing member 19 in the form of a in the housing 17th held down screwed screw plug.
- the Housing member 19 engages with a sealing edge 20 on the cylinder side facing away from the valve plate 18 and is circumferentially with a sealing ring 21 relative to the housing 17 sealed.
- the valve plate 18 is circumferentially of an annular space 22 surrounded, in which a line branch of the Delivery line 3 opens.
- the valve plate 18 is a coaxial with the Cylinder chamber 9 extending, stepped through hole 24 provided. Coaxial to the through hole 24 is in the housing member 19, a blind hole 25 is formed.
- the valve plate 18 is also provided with a radial running stitch channel 26 provided, which is located between the circumferential annular space 22 of the housing 10 and the stepped through bore 24 extends.
- the stitch channel 26 opens into a bore section 27 of the Through hole 24, between a cylinder space side annular collar 28 and a facing away from the cylinder space bore section 29 of Valve plate 18 is located.
- Cylinder space side is on the annular collar 28 of the valve plate 18th a hollow cone-shaped valve seat 31 of the first Check valve 10 is formed.
- This one has plate-shaped closing member 32, which against the Valve seat 31 is conically limited. Because of each other Deviating cone angle touch closure member 32 and Valve seat 31 along an edge whose diameter at the same time the clear diameter of the annular collar 28 is. Notwithstanding the embodiment, the closing member 32nd also only be disc-shaped and with a flat valve seat 31 cooperate with the valve plate 18.
- the Closing member 32 is a shaft 33, which the Through hole 24 of the valve plate 18 at a distance penetrates and in the blind hole 25 of the Casing component 20 ends.
- a hollow cone-shaped valve seat 35 of the second Check valve 11 is formed.
- Taper angle agrees the sealing diameter of the second Check valve 11 with the clear diameter of the Ringbund 28 coincide.
- the sleeve-shaped closing member 36 of second check valve 11 is remote in the cylinder space Bore portion 29 of the valve plate 18 largely pressure-tight and extends into the blind hole 25 of the housing member 19.
- the sleeve-shaped closing member 36 includes with his bottom 37, the shaft 33 of the closing member 32 with radial play.
- a prestressed Compressed spring 39 received, which on the one hand to the cylinder side facing away from the sleeve bottom 37 and on the other hand to a stop 40 on the closing member shaft attacks.
- the two compression springs 38 and 39 practice one each Closing force on the associated check valve 10 and 11 respectively out.
