Definitions
- the invention relates to a high-pressure fuel pump for an injection system of internal combustion engines, with a Pump housing, with at least one pump element and with a camshaft for driving the pump element.
- Such a high-pressure fuel pump is, for example, from EP 0 481 964 B2 known.
- This high pressure fuel pump is required a pre-feed pump, which fuel from a Fuel tank to the pump element of the High pressure fuel pump promotes.
- the invention has for its object a High-pressure fuel pump with integrated pre-feed pump to provide the simple structure and inexpensive can be produced.
- This task is at a High pressure fuel pump in an injection system from Internal combustion engines, with a pump housing, with at least one pump element, with a camshaft for Drive of the pump element solved in that the Pump housing, the camshaft and one with the camshaft interacting blocking wings form a blocking pump, and that the vane pump fuel at least promotes a pump element.
- Pre-feed pump becomes an otherwise necessary electrical Pre-feed pump entirely or at least for the most part dispensable.
- existing components such as the pump housing and the Camshaft are the cost of the invention Vane pump very low.
- the number also increases of the required components only around a locking wing, so that the assembly is not significantly more complex.
- the invention Vane pump does not require any additional installation space in modern internal combustion engines and modern vehicles is only available to a very limited extent.
- a particularly simple embodiment of the Vane pump according to the invention provides that on the a side of the locking wing facing the pressure chamber is provided and that the groove is part of the first hydraulic connection is. This allows the first hydraulic connection with the least possible effort will be realized.
- the Pressure chamber opposite the pump element so that at least partial radial force compensation for the camshaft is created and also the volume of the suction space regardless of the position of the piston of the pump element is.
- roller tappet is guided in the pump housing and that between the side facing away from the interior Roller tappet and the suction chamber a second hydraulic Connection is provided so that pressure equalization is possible.
- the side of the Roller tappet with the pressure of the first hydraulic Connection is applied so that the roller tappet by the hydraulic force acting on it against the Camshaft is pressed.
- this embodiment can have a spring between the pump housing and roller tappet omitted.
- a throttle can be provided.
- High pressure fuel pump can be replaced by a Suction throttle control or by controlling the excess Delivery rate during the delivery stroke of at least one Pump element take place, so that each for one certain application cheapest flow control can be used.
- Camshaft several cams distributed over the circumference has and / or in one piece with a shaft, in particular a balancer shaft or a camshaft, the Internal combustion engine is executed and / or that the High-pressure fuel pump on the internal combustion engine is flanged so that the flow rate of the High-pressure fuel pump according to the invention by the Design of the camshaft can be varied within limits and the construction effort and the space required be reduced.
- the high-pressure fuel pump according to the invention can especially in a fuel injection system High pressure fuel storage (common rail) used become.
- a first embodiment of an inventive High-pressure fuel pump is in Fig. 1a in Longitudinal section, in Fig. 1b in cross section along the Section line A-A shown.
- the high pressure fuel pump consists of a pump housing 1 and a camshaft 3.
- the camshaft 3 is cam-shaped on the right and left Section 5 of the camshaft 3 in a first bearing cover 7 and a second bearing cap 9 rotatably mounted.
- the first bearing cover 7 can also be part of a Be cylinder head of an internal combustion engine and the Camshaft 3 can be made in one piece with the camshaft Internal combustion engine to be executed.
- Seals 11 Between the pump housing 1 and first bearing cover 7 and second bearing cover 9 are Seals 11 provided.
- the cam-shaped section 5 of the Camshaft 3 actuated via a roller tappet 13 Pump element 15, which in the cross-sectional view 1b can be clearly seen.
- FIG. 1b also shows that the pump housing 1 is made in two parts.
- the two parts of the Pump housing 1 are in Figs. 1a and 1b with 1a and 1b designated.
- the pump element 15 essentially consists of a Pump piston 17, which seals in a cylinder bore 19 is led.
- the Pump piston 17 By rotating the camshaft 3, which in Fig. 1 is indicated by an arrow, the Pump piston 17 into a via the roller tappet 13 oscillating movement offset.
- Fig. 1b not in detail represented means, such as a snap ring, a Spring washer or the like, the pump piston 17 with coupled to the roller tappet 13 so that the pump piston 17 oscillates when the Camshaft 3 is rotated.
- the pump housing 1a is an interior with a cylindrical Geometry left out.
- the diameter of the interior 31 corresponds to the tip circle of the cam-shaped section 5 the camshaft 3, so that there is almost no gap between the Cam 33 of the cam-shaped section 5 and the interior 31 remains.
- the locking wing 37 is a second Compression spring 39 against the cam-shaped section 5 pressed.
- the cams 33 and the locking wing 37 share the Interior space 31 into a suction space 41 and a pressure space 43.
- the first hydraulic connection 45 Between the pressure chamber 43 and the inlet valve 25 of the Pump element 15 is a first hydraulic connection 45 available.
- the first hydraulic connection 45 consists of a variety of interconnected holes and a groove 47 in the locking wing 37, which on the Pressure chamber 43 facing the same side is arranged.
- In the first hydraulic connection is also one Metering device 49 arranged. So that's it Embodiment according to FIG. 1 with a Suction throttle control equipped. However, the invention is not on high pressure fuel pumps with such Scheme limited.
- a second hydraulic connection 53 provided that the free movement of the roller plunger 13th in the pump housing.
- camshaft 3 If the camshaft 3 is driven, it will Pump element 15 and the interior 31, cam-shaped Section 5 and locking vane 37 formed locking vane pump operated simultaneously.
- the vane pump always delivers enough fuel in the first hydraulic connection 45, so sufficient in all operating conditions Fuel for the pump element 15 is available.
- Fuel for the pump element 15 is available.
- several pump elements 15 can also be used be supplied with such a vane pump.
- the second compression spring 39 must Locking wing 37 against the cam-shaped section 5 press. Once the pressure in the first hydraulic section 45 is constructed, the locking wing 37 is additionally by pressing this pressure against the cam-shaped section 5, what the seal between suction chamber 41 and pressure chamber 43 improved.
- the excess pumped by the vane pump Fuel is a pressure control valve 63 and a Bore 55, which is visible in Fig. 1a, in the Suction chamber 41 returned. Also opens into the bore 55 a fuel inlet 57, from which fuel from a not shown fuel tank in the High pressure fuel pump arrives. With certain Use cases is between the not shown Fuel tank and the fuel inlet 57 another electric feed pump (also not shown) integrated.
- FIGS. 1a and 1b are a second embodiment of the High-pressure fuel pump according to the invention shown.
- the same components are provided with the same reference symbols and what has been said regarding FIGS. 1a and 1b applies corresponding.
- the required pressing force of the roller tappet 13 on the cam-shaped section 5 applied hydraulically.
- a pressure control valve 63 ensures that the Contact pressure of the roller tappet 13 on the cam-shaped Section 5 remains within predetermined limits.
- In the second hydraulic connection 53 is a throttle 65 intended.
- the piston 17 is via a spring washer 67 coupled to the roller tappet 13.
