Definitions

  • the invention relates to a valve arrangement, in particular a valve arrangement for a high pressure pump for a common rail system.
  • a high-pressure pump in addition to a piston driven by an eccentric, also has a valve arrangement with active or passive valves.
  • the valve assembly is usually integrated by a high degree of integration in sandwich construction directly into the pump, which is done for example by means of pressing and welding operations and accompanying adjustment processes.
  • the valve assembly can be tested in such a production, however, only directly in the pump, so that in case of malfunction of the valve, the entire pump is rejected.
  • DE 10 2010 031 600 A1 discloses a high-pressure pump having a pump element received in a cylinder head and having a suction valve for supplying fuel into the pump element, a closure screw being inserted into the cylinder head which applies an axial force to a suction valve plate of the suction valve applies.
  • the object of the invention is therefore to propose a valve arrangement for a pump, which allows a reliable and also still removable mounting on or in a pump, at the same time installation-related damage Sealing rings prevented and still has a compact construction possible.
  • a valve arrangement for a high pressure pump which has a pump housing with a recess, a valve housing, which is designed to correspond with the recess in the pump housing, so that it can be inserted into the recess, and has a clamping disc.
  • the valve housing has at least one radial projection with a first axial boundary surface and one of these oppositely disposed second axial boundary surface.
  • the clamping disk extends radially over the radial projection of the valve housing and has a third axial boundary surface which rests flush on the second axial boundary surface of the valve housing.
  • the clamping disk has a thread on the circumference, which can be screwed into a thread on the inside of the recess in such a way that the valve housing is clamped by the clamping disk with the first axial boundary surface in the pump housing.
  • valve housing is designed by inserting or insertable by the corresponding configuration in the recess of the pump housing.
  • the interfaces between the valve housing and the pump housing can be configured with conventional sealing rings or the like, which are not rotationally moved due to the lack of screwing the valve housing in the pump housing. The reliability of the sealing effect of the sealing rings is therefore not affected by the nature of the assembly.
  • the radial projection of the valve housing is suitable for carrying out a tensioning of the valve housing with the pump housing via the clamping disk which can be screwed into the pump housing. Due to the high operating pressure in high-pressure pumps of 350 bar or more act on the valve relatively large axial forces that must be absorbed by the attachment of the valve housing. The circumferential arrangement of a thread and the tension of the valve housing with the pump housing leads to a much more favorable absorption of these axial forces, the displacement of the thread radially outward still requires a much smaller dimensioning of the thread and thus allows a compact design of the valve assembly.
  • the recess has a shoulder on which the first axial boundary surface of the valve housing rests. This step can thus provide an annular boundary surface for clamping the valve housing in the pump housing.
  • the shoulder is preferably a stepped transition from a larger inner diameter to a smaller inner diameter. The larger inner diameter could be about the inner diameter of the thread in the recess or fall below this.
  • the recess may have a further shoulder, which leads to a blind hole-like design of the inner portion of the recess.
  • a cylindrical portion of a valve housing can be easily inserted, wherein the valve housing should be easy to insert into the recess.
  • This inner portion of the recess is hereinafter referred to as sealing portion.
  • the sealing portion is designed with a suitable for sealing via a sealing ring fit, wherein the valve housing in a corresponding, cylindrical portion has an annular, circumferentially arranged annular groove in which a sealing ring is arranged.
  • a support ring may be arranged in the annular groove, which prevents extrusion of the sealing ring in a sealing gap formed between the annular groove and the recess.
  • the second axial boundary surface of the valve housing which faces the clamping disk, has a shoulder which extends axially towards the clamping disk. Consequently, the third axial boundary surface on the clamping disc also have a shoulder which corresponds to the shoulder on the second boundary surface of the valve housing.
  • a centering effect can be produced by means of which a particularly precise alignment of the valve housing is produced and / or maintained when the tensioning disk is screwed to the pump housing.
  • the tensioning pulley has a fourth axial limiting surface arranged opposite the third axial limiting surface and provided with a receiving profile for a tool. Since valve components can extend axially over the pump housing through the clamping disk and the clamping disk could continue to submerge almost completely in the pump housing, it is particularly advantageous if a corresponding tool for screwing the clamping disk can be arranged detachably on the clamping disk. This is achieved by such a profile for receiving a tool, which may have completely different shapes. In addition to spaced apart from a rotation axis bores, between which a kind of claw key can be arranged, also regular, continuous profiles, such as a star-shaped recess are conceivable.
  • valve housing and the clamping disc each have a bore whose diameters correspond with each other.
  • An actuator housing of an actuator of a volume control valve is inserted through the two corresponding bores in the valve housing.
  • Coils of a control electromagnet may be arranged around this actuator housing. Another, surrounding the magnet housing could also be bolted to the clamping disc.
  • the invention further relates to a high-pressure pump with such a valve arrangement.
  • the high pressure pump is in this case in particular the high pressure pump of a common rail system.
  • FIG. 1 shows the valve assembly in a sectional view.
  • the Figures 2a) - 2c ) show differently designed clamping disks with recording profiles for receiving a tool.
  • Fig. 1 shows a valve assembly 2 with a valve housing 4, a clamping plate 6 and an actuator 8 in an actuator housing 10.
  • a core component of the valve assembly 2 is a valve stem 12 which is pressed by a spring 14 on a stop 16, wherein the actuator 8 is an axial movement of the valve stem 12 can exert against the spring force.
  • the opening area between the valve tappet 12 and the valve seat 60 is controlled via the actuator 8.
  • the size of the volume flow from a fluid inlet 18 is controlled to an output 20.
  • valve arrangement 2 In order to be able to test and / or replace the individual components of the valve arrangement 2 separately, the valve arrangement 2 according to the invention has a mechanical separation of functions, which leads to the construction shown.
  • the valve housing 4 is designed such that it can be inserted into a recess 22 of a pump housing 24. This means that the valve housing 4 can be pushed into the recess 22 by an axial movement and in this case no rotation, for example for screwing, is necessary.
  • the recess 22 is provided as a blind hole with a flat bottom or with a kegligen reason, with this the output 20 connects.
  • the recess 22 is cylindrical in the region of the outlet 20, as well as the valve housing 4 has a cylindrical portion 26 whose outer diameter corresponds to the inner diameter of the recess 22.
  • the cylindrical portion 26 has a circumferentially arranged annular groove 28 with a support ring which carries a sealing ring 30.
  • the pump housing 24 has a shoulder 34, wherein the inner diameter of the shoulder 34 is smaller than the outer diameter of a projection 36 of the valve housing 4.
  • the valve housing 4 passes when inserted into the recess 22 with a first axial boundary surface 5 in a stop the shoulder 34, so that the geometric positions of inflow channels of the inlet 18 with flow openings 38 of the valve housing 4 correspond.
  • the clamping ring 6 is used for clamping the valve housing 4 with the pump housing 24. This is configured such that on its outside circumference a thread 40 is arranged, which corresponds to a thread 42 of the pump housing 24. The resulting from the high pressure of a common rail system hydraulic force FH is compensated by an applied by means of the clamping ring 6 axial clamping force FS.
  • the valve housing 4 has, on a side facing the clamping ring 6, a second axial limiting surface 44 which corresponds to a third axial limiting surface 46 on a side of the clamping ring 6 facing the valve housing 4.
  • the clamping ring 6 rests during screwing therefore with the third axial boundary surface 46 on the second axial boundary surface.
  • the second axial boundary surface 44 may be bounded by a shoulder 45, which forms an annular plateau facing away from the clamping ring 6.
  • a shoulder 47 of the clamping ring 6 correspond, so that automatically takes place during clamping of the clamping ring 6, a centering of the valve housing 4.
  • the clamping disk 6 is preferably dimensioned such that it is flush in a strained state of the valve housing 4 flush with the pump housing 24 or even slightly immersed in this.
  • valve housing 4 and the clamping disk 6 further each have a central bore 50 and 52, which have the same diameter, so that the actuator housing 10 in the two aligned bores 50 and 52 can be inserted.
  • the remaining components of the actuator 8 can be attached to the clamping disk 6 after assembly of the actuator housing 10.
  • valve assembly can be configured as a separate hydraulic assembly significantly shorter and much more compact. This is achieved by the outsourcing of the thread on an outsourced by the valve housing component having a much larger outer diameter than the cylindrical portion 26. Consequently, a shorter thread is necessary to introduce the same clamping force.
  • valve housing 4 must only be plugged in and a rotation of the valve housing 4 is eliminated, which advantageously exerts on the sealing effect of the sealing ring 30.
  • Fig. 2a - 2c show different receiving profiles 54, 56 and 58 in a clamping disc 6, which are designed to receive a tool. While Fig. 2a shows four radially outwardly extending recesses 54 on the bore 52 is in Fig. 2b proposed to use separate, radially spaced from the bore 52 holes 56. Fig. 2c shows a series of circumferentially arranged on the bore 52, triangular recesses 58 which extend the bore 52 to a tooth profile.
  • Allen recording profiles should be common, however, that a distance to a rotation axis of the clamping plate 6 is maintained and At least two recesses should be present to allow the insertion of the tool outside the central bore 52.
