Definitions
- the invention is based on a fuel injection pump the genus of the claim.
- a fuel injection pump the pressure medium supply to the cylinder bore via Check valve, while the pressure medium drain over the Return spring receiving space runs.
- the one Face of the spool exposed to control pressure limited over the entire diameter of the cylinder bore in this the control room, on the other hand via a throttle is connected to a control pressure inlet.
- Such Spray adjusters are very sensitive to Control pressure fluctuations and tend to the Control spool vibrating relative to the spray adjuster Executes movements, resulting in an unstable Working behavior of the injection adjuster leads. It has Throttle bore the effect of kickbacks on the side the control pressure supply resulting from the operation of the Fuel injection pump arise as little as possible on the Control spool should affect, but will balanced mean working pressure in the control room is effective, only incompletely achieved.
- the fuel injection pump according to the invention with the has characteristic features of claim 1 in contrast, the advantage that the spool in its Movements are additionally dampened, so that in Control room pressure fluctuations do not occur immediately reach stimulatingly on the control spool. Will the Control piston must vibrate due to pressure surges the one enclosed in the blind hole by the pin Liquid is initially displaced through the throttle gap become. The resulting throttling effect is suppressed effective the tendency of the control piston to vibrate.
- Fuel injection pumps of the distributor type can either as pumps with one as both distributor and Pump piston serving axially driven pump piston can be provided, or radial pistons can be provided are arranged radially in a distributor Promote the delivery channel.
- a so-called radial piston pump the known type is shown in section in Figure 1.
- Four pump pistons 1 are provided, which in the same angular distance in a common radial plane to Axis of distributor 2 in radial bores 3 of distributor 2 are tightly slidably mounted.
- the distributor opening control outgoing injection lines on the circumference of the distributor, one of them with the pump piston moving inwards supplied with fuel brought up to injection pressure becomes.
- the distributor is shown by not shown Means driven in rotation by a drive shaft such that, on the one hand, the distributor opening has its control function can execute and on the other hand that the pump piston be moved in the circumferential direction.
- the cam ring 8 represents the essentially stationary part of the cam drive of the pump pistons. While the device moving the pump piston, the e.g. B. the roller plunger 6 leading ring 9 can be the is coupled to the drive shaft, the moving part of the Represent cam drive.
- the cam ring 8 has a nose 14 which in a recess 15 in an injection piston 16 whose cylindrical surface engages.
- the injection adjustment piston is tightly displaceable in a cylinder 17 and closes with its one end 18 with the closed End of the cylinder 17 a work space 20 and with its opposite, other end face 21 in there also closed cylinder a spring chamber 22.
- a return spring 23 is arranged on the one hand on a wall 24 closing the cylinder 17 and on the other hand on the end face 21 of the adjusting piston 16 supports and thus strives to clamp the injection adjustment piston 16 with its one end face 18 in contact the wall 25 closing the cylinder 17 opposite bring to.
- a control slide 28 27 is provided, which opens towards the spring chamber 22.
- the control slide 28 used there closes with a End face 29 with the closed end of the cylinder bore a control room 30 and protrudes with its other End in the spring chamber 22, where it from a control spring 31st is acted on, which on the other hand also on the Wall 24 supports.
- Parallel to the cylinder bore 27 runs in Adjusting piston starting from one end face 18 Connecting line 32, which is radial in the area of the overlap opens into the cylinder bore through the spool.
- This junction can by a collar 33 of the Control spool are closed, this ring collar a first annular groove on both sides: 34 and a second annular groove 35 limited and into the first annular groove 34 via a throttle 36 is connected to the control chamber 30 and the second annular groove 35 with an axial blind bore 37 as a pressure medium outlet the spring chamber 22 is connected, which in turn via a Relief line 38 is relieved.
- the ring collar delimiting ring edges are control edges through which at a relative displacement of the control spool Connecting line 32 either via the first annular groove 34 a pressure medium inlet 39 or the second annular groove 35 the spring chamber 22 is connected.
- the first ring groove 34 constantly in connection with the pressure medium inlet 39, the supplied with pressure medium from a pressure storage space 40 becomes.
- a fuel pump is used to supply the storage space 41 with parallel pressure control valve 42, through which the pressure storage space in known Way is supplied with a pressure that is essentially Speed-dependent with increasing speed of the fuel injection pump or the associated internal combustion engine increases.
- This pressure also constantly prevails in the control room 30 in such a way that the spool according to the change of this Pressure is shifted relative to its control spring, this depending on the compressed or relieved.
- the ring collar leads 33 controlling functions from such that at a increasing pressure occurring right shift of the control spool the working space 20 is supplied with pressure medium until a subsequent movement of the adjusting piston against the force of the spring 23, the connecting line 32, which was previously opened, is closed again.
- the pressure in the control chamber 30 drops the workspace 20 is relieved until the connecting line is closed again.
- the pressure in the control room 30 can still through a relief line 43, in the electrically controlled valve 44 sits, relieved or modified become.
- Pressure storage space 40 also as a fuel supply space and relief space of the high pressure part serves, act here in particular the tax operations at the end of the High pressure delivery stroke adversely on the constancy of the Control pressure. This always leads to an unstable Behavior of the injection piston or the whole Device for the start of spraying.
