Connect element to be connected with pump element group.
Background technology
This grafting pump is by known in 10 2,009 003 057 A1 of DE.The grafting pump is designed in fuel injection apparatus
Used in and with pumping cylinder lid and molding pumping cylinder pump element group, wherein, translational motion is capable of by drive shaft
Pump piston can move up and down in the cylinder holes of pumping cylinder.Here is arranged between pump element combined drive shaft and is configured to pulley jumper bar
Jumper bar, the jumper bar by pulley slide on the driving shaft and by the convert rotational motion of drive shaft for pump piston translation transport
It is dynamic.Pulley jumper bar is connected by means of connecting element with pump element group.Connecting element is configured to independent sleeve, and the sleeve passes through ring
The fixed protrusion of shape is embedded in the cannelure in pumping cylinder and with opposed flange, and the flange hooks the outer of pulley jumper bar
Put protuberance.
The content of the invention
The task of the present invention is to provide a kind of grafting pump, and the grafting pump is while configuration is simple with for jumper bar
Integrated form transports clamp device.
The task is solved in the following manner, i.e. connecting element and jumper bar single type ground construction.The configuration be primarily based on
Lower cognition：Grafting pump is mainly configured to substantially independent component by pump element group and jumper bar.These components must be in its manufacture
Transported to combustion engine manufacture person place afterwards and be there assemblied on internal combustion engine.Here exists following dangerous：Pump element group and
Jumper bar is by mistake separated from each other and thus produces due to waste product risk caused by part lose or damage.In order to avoid this
A bit, one is arranged for the connecting element that connects pump element group and jumper bar.By the connecting element and jumper bar single type ground structure
Make so as to be provided and component to be assembled quantity reduces.Thus it is verified advantageously, connecting element with punching
Bar single type ground construction because main target be set up connection connecting element configuration it is especially consistent with the configuration of jumper bar.By
This at least indistinctively changes the manufacturing expense of corresponding jumper bar.Additionally, connecting element can improve the jumper bar in cylinder holes
In translational motion when guiding.Thus reduce the possible abrasion of the component for moving each other.
In the expansion scheme of the present invention, connecting element is sleeve.Sleeve be it is a kind of can simple realization in structure
Element and can manufacture together with jumper bar without any problems.The jumper bar body of the reception pulley of such as jumper bar can be used as foundry goods system
Make, wherein, sleeve is manufactured by the corresponding modification of mold.In the finishing passes of the sliding surface of ensuing jumper bar body
In, sleeve can be processed in identical procedure of processing together.But the diameter that sleeve can also have the specific impulse body of rod smaller, makes
Obtain the contact not produced with cylinder holes.The polish of sleeve is not needed in the configuration.
In other configurations of the present invention, connecting element is constructed in the form of multiple retaining arms.In the configuration, in principle
Sleeve is made to be reduced to retaining arm, wherein, retaining arm is constructed so as to and so arranges with regard to jumper bar body so that these retaining arms are protected
Confirm the existing holding function of arranging and ensure the guide function of jumper bar body if necessary.Additionally, connecting element is used as retaining arm
Configuration has the advantages that to reduce weight, thus minimizes the quality of motion.
In other configurations of the present invention, connecting element has built-in flange, and the flange hooks what is arranged on cylinder cap
Annular tab.Reliable fixation of the jumper bar in pump element group is guaranteed by the configuration.
In the expansion scheme of the present invention, flange is abutted in annular tab in assembling ready position.This reclines
Corresponding to carrying out in the assembling ready position of transporting position.Thus, in these states, in accordance with the same of the orientation for determining
When ensure that the component determination mutual correspondence.After grafting pump is assemblied on internal combustion engine with jumper bar, flange is in annular
Reclining in contact pin is cancelled, and therefore ensures that, the component can be in the case where being not in contact with without abrasively phase each other
To motion.
In other configurations of the present invention, connecting element includes pump spring.Thus pump spring is complete for example in transportation
It is complete to encapsulate, and pump spring space is protected against the impact that foreign body (being for example also likely to be to pack residue) is invaded.
In the expansion scheme of the present invention, connecting element has at least two holding bolts, and the holding bolt hooks spring pad
Piece or annular tab.In the configuration, connecting element is minimized in terms of the physical dimension in the first configurations with regard to which, its
Mode is that jumper bar body passes through the holding bolt of connecting element and abuts on pump impulse bar foot to support the spring shim of pump spring common
Effect.But the configuration can also be combined with sleeve or retaining arm in the second configurations, the sleeve or retaining arm are connect with annular
Piece collective effect.
In the expansion scheme of the present invention, spring shim or annular tab are coefficient with holding bolt recessed with two
Groove, wherein, jumper bar can be reversed relative to pump element group.The configuration can realize particularly simple assembling, and its mode is, jumper bar
Be provided for by holding bolt import in groove and after importing the jumper bar is reversed relative to pump element group.
In the expansion scheme of the present invention, flange and/or holding bolt are manufactured with mode of texturing.Here, especially annular
Flange is manufactured with mode of texturing by corresponding instrument with after the engagement of pump element group in jumper bar.

Specific embodiment
Fig. 1 illustrates the vertical section of grafting pump, grafting pump being partially installed on internal combustion engine as fuel injection apparatus.Combustion
Material spraying equipment has fuel tank, and the fuel of deposit is supplied to grafting pump by fuel low-pressure system from the fuel tank, and this is inserted
Connect pump the fuel of supply is preferably supplied in high pressure accumulator.Will there in until 3000bar from high-pressure storage
Storage fuel under pressure is extracted by fuel injector, for being ejected in the combustor attached troops to a unit of internal combustion engine.It is constructed so as to
Fuel injection system is common-rail injection system and is for example designed for conveying the diesel oil of auto-ignition internal combustion engines.
Grafting pump is had pump element group 1 and is passed through with 1 coefficient jumper bar 2 of pump element group, the pump element group and jumper bar
Connecting element is connected with each other.Pump element group 1 and jumper bar 2 are at least partly installed to the housing in the internal combustion engine housing 4 of internal combustion engine
In groove 3, wherein, jumper bar 2 mainly have jumper bar body 25 and with the coefficient pulley 5 of the jumper bar body, the pulley is in camshaft 7
Cam 6 sliding surface on during the rotational motion of camshaft 7 slide, the camshaft as internal combustion engine ingredient arrange
In internal combustion engine housing 4.Thus the rotational motion of camshaft 7 is transformed into the pump piston 8 of the ingredient as pump element group 1
Parallel-moving type move up and down.Therefore, pump piston 8 is supplied to the fuel of grafting pump and is transported in high-pressure storage.
Pump element group 1 has pumping cylinder lid 9, and a pumping cylinder 11 with cylinder holes 10 is molded on the pumping cylinder lid.Pump piston 8 is in pump
Be directed in cylinder 11 and with the extension of the cylinder holes 10 for being arranged in pumping cylinder lid 9 in pump work chamber collective effect, the pump work
Make chamber to be connected with fuel low-pressure system by inlet valve and be connected with high-pressure storage by outlet valve.It is downward in pump piston 8
