Definitions

  • the invention relates to a Druckregeiventii with a housing having a reference pressure port and a reference pressure chamber, a Voryakan gleich and a pre-pressure chamber and a Regefchristanscbiuss and io Regeiyakhunt cooperating with a movable axially in the housing control member such that a desired control pressure between a form , which is applied to the admission pressure port and a reference pressure, which is applied to the reference pressure port, can be adjusted.
  • the second sealing means comprises a second sealing member which is positively arranged in the housing and / or in the control member, but is spaced in the radial direction of the control member.
  • control member is designed in several parts, wherein a longitudinally extending hollow body is provided, which has at its two ends a first sealing member of the first sealing means and a third sealing member of the third sealing means.
  • a longitudinally extending hollow body is provided, which has at its two ends a first sealing member of the first sealing means and a third sealing member of the third sealing means.
  • the reference pressure chamber is connected via the channel formed as a cavity in S85güed with the control pressure chamber. It is advantageous that the control member is movable by a valve stem of the drive direction.
  • the second sealing member is then arranged between the longitudinally extending hollow body and the first sealing member.
  • the housing is advantageously constructed from a first, second and third Gepuruseteii.
  • the second sealing member may be arranged between the first and second housing part.
  • the figure shows a Druckregeiventif 1 with a housing 2, which has a Referenzdruckanschius 3 and a reference pressure chamber 4, a form pressure port 5 and a pre-pressure chamber 6 and a Regei réelleanschfuss 7 and a control pressure chamber 8. Furthermore, in the housing 2, a control member 9 is arranged, which is mounted movably in the axial direction. By means of an oscillating movement of the control element 9, a desired regulating pressure, which results from the admission pressure applied to the admission pressure port 5 and a reference pressure applied to the reference pressure port 7, can be set. The minimum control pressure thus corresponds to the reference pressure, usually the atmosphere and the maximum control pressure corresponds to the pre-pressure applied to form pressure port 5.
  • a drive device 10 which acts on the control member 9.
  • an electromagnetic drive is provided, however, other drive devices, such as pneumatic, electromotive drive devices may be used, in the present case, the drive device 10 is only fragmentarily shown to be irrelevant to the essence of the invention.
  • the valve lifter 26 driven by the electromagnetic drive 10 has a sealing surface 22 which, together with a first sealing element 14, forms a first sealing device.
  • This first sealing device 11 serves to seal the reference pressure chamber relative to the control member nd thereby also relative to the control pressure chamber 8.
  • a second sealing device 12 is provided, which according to the invention consists of a sealing member 15 designed as a sealing ring which is arranged positively in both the housing 2 and in the control member 9.
  • control member 9 is executed in several parts, wherein a longitudinally extending hollow body 17 is provided, which has at its two ends the first sealing member 14 and the third sealing member 16.
  • the housing 2 consists of a first housing part 19, a second housing part 20 and a third housing part 21.
  • the radially outwardly directed side of the second sealing member 15 can be arranged between the first housing part 19 and the second housing part 20 and radially inwardly directed side of the sealing member 15 between the longitudinally extending hollow body 17 and the first sealing member 14 may be arranged.
  • the valve stem 18 is biased over the sealing surface 22 by means of a first spring means 23 with respect to the first housing part 19.
  • the third sealing member 16 is biased by a second Federmittei 25 relative to the third housing part 21.
  • a membrane for sealing the drive device 10 with respect to the reference pressure chamber 8 is still provided. It is entirely conceivable that the membrane 26 simultaneously forms the first Federmittei 23, so that the spring provided here may be omitted.
  • the pressure control valve works as follows:
  • the valve tappet 26 and thus the sealing surface 22 are moved in the direction of the control member 9.
  • the reference pressure chamber 4 is sealed against the Regeiyakhunt 8.
  • Another movement will cause the sealing member 16 lifts from the sealing surface 24 and the pre-pressure chamber 9 connects to the control pressure chamber 8, so that a medium with the applied form in the control pressure chamber 8 can pass.
