By the pressure piping of attaching troops to a unit, available a kind of pressure medium of taking from the precharge pressure of suitable accumulator loads the hydraulic pressure unit that constitutes described actuator.Here, accumulator can relate to a kind of so-called shared trunk (common rail) 14, in any case it is by all cylinders 1 or one group of cylinder 1.Here can shared trunk 14 be loaded by the pump 15 usefulness pressure mediums that bent axle 5 drives by one.
In order to control the pressure-loaded of above-mentioned actuator, some control valves are set attaching troops to a unit in the pressure piping of these actuators.For limiting the quantity of needed control valve, the actuator of the work of staggering in time can be equipped with a public control valve.For example, the actuator of the exhaust valve 7 of each cylinder and Injection Pump 8 can be equipped with a public control valve.In structural type based on Fig. 1, the Injection Pump 8 of two different cylinders 1 is equipped with a public control valve device 16, the control valve device is connected with shared main line 14 by a pressure piping 17a and is connected with the actuator of attaching troops to a unit by pressure piping 17b, c, alternately with pressure actuator is loaded by the control valve device.What conform with purpose is, its Injection Pump 8 be equipped with the cylinder 1 of a public control gear 16 relate to those by firing order each other from cylinder far away as far as possible, thereby make stagger on the time longer.Control valve device 16 drives (getacktet) by engine signal, and engine signal is received by suitable sensor and is provided with a suitably control valve device 16 of inlet by signaling line 18 inputs that a with dashed lines schematically illustrates.
As seen from Figure 2, control valve device 16 for example comprise one contain the inlet that is useful on signaling line 18 lead control valve 19 and mating reaction, that be designed to a guiding valve with it main control valve 20.Main control valve has a block shell 21 and a main valve plug 22 that is arranged on movably in the shell aperture of attaching troops to a unit.Shell 21 have one can via pressure piping 17a and the inlet 23 that here in form is connected for the pressure medium source of shared trunk 14 with two place its both sides, via pressure piping 17b, c can with to be loaded here be the outlet 24 and 25 that the hydraulic pressure unit of two Injection Pump 8 actuators is connected in form.With them outlet 26 that some are adjacent, that can be connected with an apiezon oil case can also be set abreast.Above-mentioned entrance and exit is connected by the interior circular groove in the hole and the zone in the hole that holds main valve plug 22 of shell 21.
The to-and-fro motion of main valve plug 22 is by being caused by the engine signal of leading control valve 19 respective handling.The skew each time for main valve plug 22 here all needs an engine signal, and it can be converted to a suitable instruction by leading control valve 19.Main valve plug 22 is by the cyclic movement of the engine signal of attaching troops to a unit.If the proper engine signal do not occur at the inlet of leading control valve 19, main valve plug 22 position that should automatically be placed in one for the reason of Security then, in this position, the outlet 24,25 that is connected with the actuator of attaching troops to a unit and with here isolate for the inlet 23 of the pressure-source communication of shared trunk 14 in form.Send the neutral position back to for the laterally offset that realizes main valve plug 22 and with it, be provided with one and attach troops to a unit in the Effector of main valve plug 22.
In case described Effector is used for forming according to pass to the centralising device that the signal of leading control valve 19 realizes that the shifter of main valve plug 22 position deflection in the middle of it and are used for realizing when signaling line 18 no signals that main valve plug 22 returns the neutral position automatically by signaling line 18 by one.
In order to constitute shifter, at least two hydraulic type cylinder-piston units 27 opposite each other with respect to main valve plug 22 are set, they have a mobile piston 29 that limits pressure chamber 28 borders, the distolateral mating reaction of respectively facing of mobile piston and main valve plug 22 respectively.For this reason in illustrated embodiment, mobile piston 29 is provided with the adjacent press-on pins 30 on distolateral of each that be bearing in main valve plug 22 shown in Fig. 2 and 3.Attaching troops to a unit alternately activates in the cylinder-piston unit 27 of two ends of main valve plug 22, that is to say, move right in order to make main valve plug 22, and the cylinder-piston unit 27 on the activation left side, and the cylinder-piston unit 27 on passivation the right, otherwise or.
For active cylinder-piston unit 27, use the pressure medium at inlet 23 places that are present in shell 21 that related pressure chamber 28 is loaded.Be provided with for this reason that some are 23 that link to each other with inlet, can be by leading the flow channel of control valve 19 according to the SC sigmal control opening and closing that exist.Lead control valve 19 and contain an electronic component 19a and the mechanical component 19b that influenced by it that comprises the inlet that is used for signaling line 18, the latter presses the type design of magnetic slide valve, as main control valve 20, it has an inlet can replace the outlet that is connected with it with two, and its spool can be by being moved according to the regulating command that the engine signal that exists produces by electronic component 19a.
Be given for to two oppositely with flow channel that the pressure chamber 28 of the cylinder-piston unit of main valve plug 22 mating reactions carries out pressure-loaded comprise, the branch road 31a that is in the inlet of leading control valve 19 23 that is communicated with and two with inlet from the outlet of leading control valve 19, respectively towards branch road 31b, the c of one of two cylinder-piston units 27, they alternately are connected with branch road 31a.As main control valve 20, to lead control valve 19 and also can be provided with outlet additional, that be not shown specifically, that lead to no pressure oil tank here, they can make branch road 31b or 31c unloading.
In order to constitute shifter, in principle, a distolateral cylinder-piston unit 27 that is equipped with of each of main valve plug 22 is just much of that.In illustrated embodiment, each of main valve plug 22 be distolateral to be equipped with two cylinder-piston units 27 of 180 ° that stagger each other, and this has guaranteed to import into respect to the power of main valve plug 22 axis symmetries and has prevented the crooked of main valve plug 22 then.
At the side direction end position of main valve plug 22, as shown in Figure 3, it is with in front distolateral abutting on the mechanical stop in shifter.The mobile piston 29 of this cylinder that is equally applicable at this moment activate-piston unit 27 is as by Fig. 3 the right as seen.Be hard impact and the mechanical stress associated therewith of avoiding main valve plug 22, mobile piston 29 can be equipped with the buffer 32 of its reseting movement of braking.Here it can relate to act on mobile piston 29 away from the pressure spring on the rear side of spool, when the mobile piston 29 of attaching troops to a unit separately moved backward, pressure spring compression was shown in Fig. 3 left side.
In order to constitute centralising device, be provided with that some are other, with respect to main valve plug 22 opposite each other, oppositely with its mating reaction, in Fig. 2 and 3 a with dashed lines hint and cylinder-piston unit 33 of in Fig. 4 to 6, being shown specifically.Equally in principle, it is just much of that in each side a cylinder-piston unit 33 to be set here.Yet appropriate is, each distolateral two cylinders-piston unit 33 that is provided with at main valve plug 22, they stagger 180 ° and stagger 90 ° respectively with respect to the cylinder-piston unit 27 of shifter each other, so that all cylinder- piston unit 27 or 33 evenly distributes on 360 °, thereby should be able to prevent crooked phenomenon.
Cylinder-piston unit 33 comprises a mobile piston 35 that limits pressure chamber 34 borders respectively, and it is provided with a press-on pins 36 that can place with the abutting end side contacts of main valve plug 22.All the time be activated by the centralising device that cylinder-piston unit 33 constitutes.Correspondingly, continue pressure chamber 34 to be loaded with pressure.For this reason, the pressure chamber 34 of cylinder-piston unit 33 is connected with the annular groove of the inlet 33 of shell 21 or connection with it by flow channel 37a, the b that can not end.But, can be applied to locomotivity on the main valve plug 22 less than being applied to the locomotivity on the main valve plug 32 by cylinder-piston unit 33 by the cylinder that constitutes shifter-piston unit 27.Therefore the centralising device of the continuous activation cylinder-piston unit 27 that can correspondingly be moved each active sides of device overcomes.For this reason, the pressure side on the qualification of the mobile piston 29 of shifter pressure chamber 28 borders of respectively attaching troops to a unit is greater than the pressure side on preferred pressure chamber 34 borders of respectively attaching troops to a unit greater than the qualification of the mobile piston 35 of centralising device twofold.
Based on above-mentioned power relation, guarantee, in case with pressure to loading in the cylinder-piston unit 2 of a side attaching troops to a unit of shifter, just can mobile main valve plug 22, this is meant the situation when the corresponding engine signal 7 of one of existence.If the cylinder of shifter-not activation of piston unit 27, that is to say and do not have corresponding engine signal, then main valve plug 22 automatically places the neutral position based on Fig. 4 by lasting cylinder with the pressure-loaded-piston unit 33 of centralising device, in this position, the inlet 23 be cut off and export 24,25 with the inlet 23 isolation, locking is attached troops to a unit in the unit of outlet 24,25, locking Injection Pump 8 in illustrated embodiment thus.Therefore in pressing the embodiment of Fig. 1, can not cause undesirable injection.
The mobile piston 35 of cylinder-piston unit 33 and the press-on pins 36 that is attached thereto load with the power towards main valve plug 22 directions constantly by the pressure that continues to exist in the pressure chamber 39 of respectively attaching troops to a unit.Some mechanical stop restrictions that move through towards main valve plug 22 directions that cause thus of mobile piston 35 are as can being clear that by Fig. 4 to 6.When mobile piston keeps off on the convex shoulder 38 that leans against a shell side of attaching troops to a unit with its anchor ring by press-on pins 36 limited boundaries of attaching troops to a unit, reach described stop dog position.
The length dimension of the press-on pins 36 of mobile piston 35 is designed to, when main valve plug is in its as shown in Figure 4 neutral position, the mobile piston 35 of respectively attaching troops to a unit the press-on pins 36 of each cylinder-piston unit 33 opposite each other of stop dog position and distolateral contact of respectively facing of main valve plug 32.In case main valve plug 22 laterally offsets, for example skew left in Fig. 5, then the mobile piston 35 of the cylinder on the left side-piston unit 33 lifts and enters in the pressure chamber 34 of respectively attaching troops to a unit from the backstop that shifts out of attaching troops to a unit, and opposed here be that the mobile piston 35 of cylinder-piston unit 33 on the right remains in backstop and firmly puts.As can being clear that by Fig. 5, the right-hand member side of main valve plug 22 is lifted from adjacent press-on pins 36 this moment.If at passivation shifter under this situation and no longer power is applied on the main valve plug 22, then this main valve plug automatically is moved back into the neutral position by the cylinder-piston unit 33 on the left side successively moved the morning of centralising device, in this position, it is by press-on pins 36 contacts of the whole cylinders-piston unit 33 of centralising device.
In order to guarantee a kind of reliable contact and to get rid of any gap, mobile piston 35 and press-on pins 36 thereof can be provided with the axial bore of a perforation radially divided and for this reason, hold one in the axial bore and shift out pin 39, when the mobile piston 35 of attaching troops to a unit be in its stop dog position and main valve plug 22 therewith away from the time, as can clearly be seen that by Fig. 6 left side, shift out pin 39 shift out by the pressure in the pressure chamber of attaching troops to a unit 34 and keep being bearing in main valve plug 22 attach troops to a unit distolateral on.
Rightly, the shell 21 of main control valve 20 is provided with sealing attaches troops to a unit in the side cover 40 in the hole of main valve plug 22, and it contains the cylinder-piston unit 27 of shifter or centralising device or 33 pressure chamber 28 or 34.Attach troops to a unit in flow channel 37a, the b of pressure chamber 34 rightly fully at shell 21 with cover 40 interior extension.Be directly installed on the shell 21 of main control valve 20 if lead control valve 19, like that, then this point also is applicable to flow channel 31a, b, the c that attaches troops to a unit in the pressure chamber 28 of shifter among the embodiment as shown.
When the usage ratio valve, an enclosed regulating loop can be set, detect main valve plug 22 corresponding positions this moment and lead the control valve as actual value input, this is led the control valve and can implement rating value-actual value and relatively also can realize required correction.In order to detect the position of main valve plug 22, main valve plug is equipped with position transducer 42 a preferred contactless job, that only schematically illustrate in Fig. 2 and 3, and it is connected with an inlet of attaching troops to a unit of leading control valve 19 by signaling line 43.
