Definitions

  • the invention relates to a high-pressure valve arrangement according to the preamble of claim 1.
  • Such high pressure valve assemblies are used in high pressure pumps, by means of which a fluid medium is brought to a pressure of, for example, 4000 bar and higher.
  • the pressure valve has an axially displaceable, spring-loaded plunger, the front side forms a sealing surface which rests against an associated end face of the valve body in case of sealing and thus sealingly closes the channel during a suction process.
  • the suction valve is provided with a spring-loaded, annular plate-shaped closing body, which abuts against the other end face of the valve body when the fluid medium is pressurized by a piston and pressed through the channel, in which case by the closing body, a suction-side inlet is sealed.
  • a plunger pump is known, with a valve arrangement in which a valve body forms the bottom for a pressure chamber, wherein with a pressure-side plunger a guided through the valve body channel is closed.
  • the invention has for its object to further develop a high pressure valve assembly of the generic type so that increased with little design and manufacturing effort their life and the usability is improved.
  • the mutually corresponding sealing surfaces between the plunger and the valve body conical or even, i. be formed transversely to the longitudinal axis.
  • the axial guidance of the plunger is effected by guide surfaces which are introduced into the valve body in the region of the chamber.
  • the so-called constant support of the plunger in the valve body also contributes to an increase in the load capacity of the high pressure valve assembly.
  • the suction valve which has hitherto been formed by the annular plate-shaped closing body described in the prior art and guided in a bore of the housing, is now also axially displaceably mounted in a guide bore provided in the valve body, whereby manufacturing technology and provide functional benefits.
  • a concentric chamber may be provided in the valve body, on the wall of which the closing body is at least partially supported for axial guidance.
  • a high-pressure valve arrangement is shown, which is provided overall with the reference numeral 3.
  • the same components of the various embodiments are provided with the same reference numerals.
  • the respective high-pressure valve arrangement 3 has a valve body 6 which is mounted on the suction side in a housing 1 and on the pressure side in a flange 2 connected to the housing 1, wherein the valve body 6 is sealed in each case by means of a static annular seal 7 with respect to the housing 1 or the flange 2 is.
  • the housing 1 is provided with inlet bores 4, through which a fluid medium is conveyed via a suction line 5 arranged in the valve body 6 into a suction chamber 11.
  • a closing body 8 the spring-loaded for closing the suction line 5 sealingly abuts the valve body 6.
  • the closing body 8 has a pin 9, which, axially extending, slidably rests in a corresponding bore 19 of the valve body 6, wherein this bore 19 forms a guide for the pin 9 and thus for the closing body 8.
  • the medium By closing the suction line 5, the medium is forced through a piston 10 in the valve body 6 into a pressure chamber 12 of the valve body 6 by means of a piston 18 in which a plunger 13 of a pressure valve is positioned coaxially with the piston 18 and the closing body 8. which closes the channel 10 in a sealing of the medium sealing.
  • the plunger 13 is stepped, with a pin 22 protruding into the pressure chamber 12, while a stepped, peripheral shoulder forms a sealing surface 16, 17, which corresponds to a matched sealing surface of the valve body 6, ie, in the sealing position of the plunger 13th with its sealing surface 16, 17 on the associated sealing surface of the valve body 6 at.
  • this sealing surface 17 of the plunger 13 as well as the associated sealing surface of the valve body 6 is conical, while the sealing surface 16 of the plunger 13 after FIG. 2 is flat, ie, perpendicular to the longitudinal axis of the plunger 13 extends.
  • Gleichgeartet are also sealing surfaces 20, 21 of the closing body 8, which rest in the case of operation on adapted surfaces of the valve body sealing.
  • FIG. 3 shows the plunger 13 with a conical sealing surface 17 which is mounted in the sense of a chamfer, while the pressure chamber 12 is adapted in the contact region of the sealing surface 17.
  • the plane end face forms the sealing surface 16, in correspondence with the bottom of the pressure chamber 12, to which this sealing surface 16 abuts.
  • the wall of the pressure chamber 12 forms a guide surface 14 for the plunger 13, to its axial guidance, wherein between the plunger 13 and the guide surfaces 14 in the open position, the fluid is fed into an outlet 15.
