Definitions
- the invention relates to an electromagnetically operated suction valve for a high-pressure pump in a fuel injection system, in particular in a common-rail injection system, with the features of the preamble of claim 1. Furthermore, the invention relates to a high-pressure pump for a fuel injection system, in particular a common-rail injection system, with such a suction valve.
- An electromagnetically actuated suction valve for filling a pump working space of a high pressure pump with fuel is an example of the published patent application DE 10 2014 200 695 A1 out. It comprises a liftable valve tappet, which is acted upon in the closing direction by the spring force of a spring. Further, an electromagnet is provided for acting on a mechanically coupled to the valve stem anchor. The armature is acted upon in the direction of the valve stem by the spring force of a further spring, which is dimensioned such that it holds open the suction valve in the absence of energization of the electromagnet. To close the suction valve, the electromagnet is energized.
- the armature then performs a lifting movement against the spring force of the other spring, so that the valve stem is relieved and is pulled by the spring force acting in the closing direction spring in a valve seat.
- the energization of the electromagnet is stopped.
- the additional spring returns the armature to its initial position, whereby it strikes the valve tappet and lifts it out of the valve seat.
- armature and valve tappets move highly dynamically. This can lead to the formation of local negative pressure range. If the negative pressure reaches a critical limit, cavitation occurs. This means that gas bubbles form, which implode on renewed increase in pressure and can lead to damage to the moving components due to cavitation erosion.
- a particularly critical area with regard to cavitation is the contact area between the armature and the valve tappet.
- the armature of the suction valve has a central bore, which is closed towards the valve tappet by an actuating body resting against the valve tappet. In the central bore protrudes from the side opposite the actuating body side into a bearing element, via which the armature is mounted.
- a connection between pressure chambers formed on both sides of the armature is formed along the outer jacket of the armature.
- the present invention has for its object to provide an electromagnetically operated suction valve for a high-pressure pump in a fuel injection system, which is less subject to wear due to a reduced risk of cavitation and therefore has a long service life.
- the electromagnetically actuated suction valve is specified with the features of claim 1.
- Advantageous developments of the invention can be found in the dependent claims.
- a high pressure pump is proposed with such a suction valve.
- electromagnetically actuated intake valve comprises an electromagnet for acting on a liftable armature, which is acted upon in the direction of a liftable valve stem by the spring force of a compression spring, so that when energized electromagnet the armature is mechanically coupled to the valve stem and holds it in an open position.
- the armature is penetrated by a central bore which connects pressure chambers formed on both sides of the armature.
- a pin-shaped displacement element provided, which dips at least during a stroke movement of the armature in the central bore of the armature.
- the displacement element that is immersed in the central bore of the armature when the suction valve is switched leads to a targeted volume displacement. This is a pressure compensation can be produced, which counteracts the formation of local negative pressure zones and thus reduces the risk of cavitation.
- the volume within the armature decreases and fuel is displaced from the bore into the pressure space below the armature.
- This is the pressure chamber which is arranged on the side facing the valve tappet side of the armature, or the pressure chamber whose volume increases due to the stroke of the armature. The volume displaced into the pressure space prevents the pressure in this pressure space from falling below a critical limit.
- a defined amount of fuel can be displaced from the pressure chamber located above the armature into the bore and thus into the lying below the armature pressure chamber via a free flow cross-section between the displacer and armature.
- the setting of the additionally displaced quantity can be specifically adjusted via the free flow cross section.
- a defined free flow cross section therefore preferably remains between the armature and the displacement element.
- the volume displacement counteracts in particular the cavitation in the contact area between the armature and valve tappet. This reduces the load on the armature and the valve tappet so that they can be manufactured from less wear-resistant materials or a wear reserve is negligible. In addition, expensive heat treatments of the components to increase the wear resistance can be omitted. This has the consequence that the manufacturing costs can be reduced.
- the displacement element has a relation to the inner diameter of the bore of the armature reduced Outer diameter. This leads to the formation of a circumferential annular gap between the displacer and the armature, which defines the remaining free flow cross-section.
- the displacement element can have at least one longitudinal groove and / or flattening on the outer peripheral side.
- the remaining between the displacer and the armature free flow cross section can therefore also be defined by an axially extending flow channel.
- the pin-shaped displacer element forms a throttle point together with the armature. This means that the remaining free flow cross section between the armature and the displacement element corresponds at least in one section to a throttle cross section.
- the armature is at least partially received in a valve body of the suction valve.
- the valve body can be used in this case to guide the armature.
- the valve body may define a first end position of the armature.
- an adjusting element can be inserted between the armature and the valve body, so that the valve body only indirectly defines the first end position. If such an adjustment element is provided, this is preferably annular and axially supported on an annular shoulder of the valve body. Since the guide of the armature is effected via the valve body, the remaining between the armature and displacer free flow cross-section can be designed arbitrarily.
- the armature can also be guided via the pin-shaped displacement element.
- the radial gap between the displacer and the armature is designed as narrow as possible.
- the intended for targeted volume displacement free flow cross section between the displacement element and the armature can then be ensured via an axially extending flow channel.
- at least one longitudinal groove and / or flattening can be provided on the outer circumference side on the displacement element-as already described above.
- the pin-shaped displacement element is preferably mounted stationary, so that the armature moves relative to the displacement element.
- the pin-shaped displacement element can be firmly connected to a pole core of the electromagnet.
- the pin-shaped displacement element can be pressed into a central recess of the pole core.
- the pole core itself can also form the pin-shaped displacement element.
- the pole core may have a pin-shaped projection which serves as a displacement element and which is formed on an end face of the pole core facing the armature.
- the armature loading pressure spring is supported directly on the pole core.
- the support of the compression spring preferably takes place directly at the anchor.
- the compression spring can be at least partially embedded in the pole core and / or in the armature. In this way, a compact construction in the axial direction is also achieved.
- the compression spring at least partially surrounds the pin-shaped displacement element.
- About the displacement element can be effected in this case, a guide of the compression spring.
- the pole core is connected via a sleeve to the valve body.
- the axial distance between the pole core and the valve body is adjustable. If, in addition, the second end position of the armature is predetermined by the pole core, the stroke of the armature can be adjusted via the axial distance.
- the further proposed high-pressure pump for a fuel injection system is characterized in that it comprises a suction valve according to the invention.
- the suction valve is preferably integrated in a housing part of the high-pressure pump, so that the housing part forms a valve seat of the suction valve.
- the advantages of the invention come particularly well, since the contact area between the armature and the valve stem is additionally burdened by pressure pulsations from a low pressure area serving as inlet for the suction valve.
- Fig. 1 electromagnetically actuated suction valve is used to fill a high pressure element space 19 of a high-pressure pump with fuel.
- the suction valve is integrated in a housing part 17 of the high-pressure pump, which at the same time forms a valve seat 18.
- the suction valve comprises a hubbeweglichen with the valve seat 18 liftable valve stem 3, which is acted upon in the closing direction by the spring force of a closing spring 21.
- the closing spring 21 is designed as a helical compression spring, which surrounds the valve stem 3 in regions and on the one hand on the housing part 17, on the other hand supported on a pressed onto the valve stem 3 spring plate 22.
- annular low pressure chamber 20 is further formed, which is bounded by a valve body 14 of the suction valve and serves as an inlet.
- the valve body 14 at the same time receives an armature 2 which can be moved in a stroke via the valve body 14 is guided.
- the armature 2 is acted upon in the direction of the valve stem 3 by the spring force of a compression spring 4, which is greater than the spring force of the valve lifter 3 loading closing spring 21, so that the spring force of the compression spring 4 keeps the suction valve open.
- an electromagnet 1 To close the suction valve, an electromagnet 1 must be energized.
- the energization of the electromagnet 1 leads to the construction of a magnetic field whose magnetic force pulls the armature 2 - against the spring force of the compression spring 4 - in the direction of a pole core 15 which defines the upper end position of the armature 2.
- the lower end position is predetermined by an annular body 23 which is supported on a shoulder 24 of the valve body 14.
- the pole core 15 is fixedly connected via a sleeve 16 to the valve body 14.
- a pin-shaped displacement element 8 is pressed in the pole core 15. This dips into a central bore 5 of the armature 2 when the magnetic force of the electromagnet 1 pulls the armature 2 in the direction of the pole core 15.
- the displacement element 8 reduces the volume of the bore 5, while the volume of a pressure chamber 7 arranged below the armature 2 increases. From the bore 5 in the pressure chamber 7 displaced fuel causes the pressure in the pressure chamber 7 does not fall below a cavitation critical range.
- an orifice 13 is formed via an annular gap 10 between the displacer 8 and the armature 2, which has a free flow cross-section 9, via a targeted amount of fuel from a located above the armature 2 pressure chamber 6 in the bore 5 and thus in the pressure chamber 7 is discharged below the armature 2. Because with the stroke of the armature 2, the volume of the located above the armature 2 pressure chamber 6 decreases and the pressure in the pressure chamber 6 increases. Via the targeted volume displacement, a pressure compensation can be effected, which significantly reduces the risk of cavitation in the pressure chamber 7, in particular in the contact region B of the armature 2 with the valve tappet 3.
- the Fig. 2a shows the suction valve in the closed position, in which the armature 2 rests on the valve stem 3.
- the volume of the pressure chamber 6 located above the armature 2 is maximum, while that of the pressure chamber 7 located below the armature 2 is minimal is.
- the immersion depth of the displacer 8 in the central bore 5 of the armature 2 corresponds in this case to the stroke h of the armature 2. However, this is not necessarily the case. For example, even at rest, d. H. when the suction valve is closed, the displacement element 8 engage in the bore 5, so that the immersion depth can also be greater than the stroke h of the armature 2.
- FIGS. 3a and 3b an alternative embodiment of a suction valve according to the invention can be seen.
- flattenings 11 on the displacement element 8 form axially extending flow channels 12, which define the remaining between the armature 2 and the displacement element 8 free flow cross-section.
- This is also designed here as a throttle cross section 13 to dissipate at a stroke of the armature 2, a defined amount of fuel from the pressure chamber 6 in the pressure chamber 7.
- the outer diameter of the displacement element 8 is designed to guide the armature 2, so that the guiding function of the valve body 14 is eliminated.
- the radial gap 25 between the valve body 14 and the armature 2 can be made large accordingly, in order to additionally bring about a pressure equalization.
