Abstract
The invention discloses a device of pump plunger rod (11) in the combustion engine, which consists of at least one cam (15) and at least one rocker (16) with rolling bulk (17), wherein the rolling bulk (17) of rocker (16) are rolling on the cam (15), which is attached by pump plunger rod (11) according to rolling movement. The plunger rod roller (21) of pump plunger can roll on the rolling bulk (17) of swaying rod (16) directly.
Description
Technical field
The present invention relates to a kind of by claim 1 device that is used for operating fuel pump as described in the preamble.
Background technique
The known in practice device that is used for operating fuel pump, the line of force or power input operate pump plunger rod, make the roll body that is attached to rocking bar on cam, roll, wherein owing to of the spin axis swing of this rolling motion rocking bar around rocking bar, and wherein the rotatable crank sidepiece by the roll body of lateral register at rocking bar is delivered to the oscillating motion of rocking bar on the plunger rod roll body that is attached to the pump plunger shaft stopper rod, cause finally thus and the oscillatory type of the interactional plunger rod roll body of pump plunger shaft stopper rod to be handled or the motion of step-by-step movement or grading type that wherein this device will be attached to the moving through on the pump plunger shaft stopper rod that rocking bar is delivered to the internal-combustion engine jet pump of control curve of cam.It is disadvantageous power being input on the pump plunger shaft stopper rod to be handled like this, because whole device bears huge mechanical load, and wearing and tearing easily thus.
Summary of the invention
The task of the present invention of setting out thus provides a kind of novel device that is used for operating fuel pump.
This task is by solving by the described device that is used for operating fuel pump of claim 1.According to the present invention, the plunger rod roll body of pump plunger shaft stopper rod rolls on the roll body of corresponding rocking bar.
In the present invention, the plunger rod roll body of operating pump plunger shaft stopper rod to be handled directly rolls on the roll body of corresponding rocking bar.This makes in the pump plunger shaft stopper rod better power transmission or obtain a kind of line of force of optimization.Bear more small mechanical load and wear and tear more small thus by the device that is used for operating fuel pump of the present invention.
Description of drawings
Preferred improvement of the present invention put case dependent claims and below explanation in obtain.Describe embodiments of the invention with reference to the accompanying drawings in detail, but the present invention is not limited to these embodiments.
Accompanying drawing illustrates:
Fig. 1 shows the device that is used for operating fuel pump by of the present invention;
Fig. 2 has rotated 90 ° viewgraph of cross-section with the view with respect to Fig. 1 and has shown details by the device of Fig. 1.
Embodiment
Below with reference to the present invention of Fig. 1 and 2 more detailed description.
Fig. 1 shows that device 10 by the pump plunger shaft stopper rod 11 of the jet pump that is used to handle internal-combustion engine of the present invention is used for to internal-combustion engine, particularly the co-rail diesel internal-combustion engine provides fuel under high pressure.This pump plunger shaft stopper rod 11 to be handled is bearing in the guiding device 12, and longitudinally the direction of medial axis 13 moves.A so-called middleware 14 that is used to connect petrolift acts on the guiding device 12 of pump plunger shaft stopper rod 11.
Comprise that by Fig. 1 at least one has the cam 15 of control curve 23 by the device 10 that is used for operate pump plunger rod 11 of the present invention, its cam 15 is designed to so-called three cams in the embodiment shown.The roll body 17 that is attached to rocking bar 16 rolls on the control curve 23 of cam 15 or cam 15.This roll body 17 can be rotated to support on the end 18 of rocking bar 16, and wherein rocking bar 16 can be around turning point 20 swings that are attached to the end 19 relative with end 18.
Plunger rod roll body 21 and pump plunger shaft stopper rod 11 interactions to be handled, the plunger rod roll body is arranged in a chamber 22 of being determined by pump plunger shaft stopper rod 11, and can be rotated to support on wherein.In the present invention, plunger rod roll body 21 directly rolls on the roll body 17 of rocking bar 16, makes plunger rod roll body 21 continuous rolling on the roll body 17 of rocking bar 16.Be used for the power input of operate pump plunger rod 11 corresponding from cam 15 to rocking bar 16 roll body 17 and directly to plunger rod roll body 21, carry out final plunger rod roll body 21 operating pumps plunger rods 11 from this roll body 17.If power is directly transmitted to the direction of plunger rod roll body 21 by roll body 17 edges from cam 15, obtain the favourable direction angle of so-called contact normal force so.By device of the present invention bear less wearing and tearing and frictional loss less.
Can be in the single camming and repeatedly camming and all types of plunger pump that is used for the motor fuel high voltage supply are applied by device of the present invention.
