Definitions

  • the valve 3 opens against the system pressure, which is shown in the schematic illustration merely as an example as a spherical valve body 9 facing the pressure medium connection 4, loaded by a valve spring 7 in the closing direction and sealingly coming into contact with a valve seat 8. There are other ways of doing this, too. It is also shown that a plunger 10, which serves to open the valve body 9 against the spring force of the valve spring 7 and the closing force resulting from the system pressure, is provided on the valve body 9.
  • the force transmission element 10, here designed as a plunger is used to transmit force from a hand lever 12, which is pivotably mounted in the gun housing 1 on the handle 2 on a pivot axis 11, to the valve body 9.
  • the force transmission element 10 assumes its uppermost position and the gear roller 16 with a little distance to the side of the abutment roller 17 lies, the effective distance of the abutment roller 17 to the pivot axis 11, ie the clear distance between the abutment roller 17 and the pivot axis 11, is less than the effective distance of the gear roller 16 to the pivot axis 11, ie here the distance between the center points.
  • the lateral distance of the center of the pivot axis 11 from the center of the force transmission element 10 is relatively small, ie the lever ratio is relatively large.
  • valve body 9 With the valve body 9 slightly open and thus largely relieved of pressure, the gear roller 16 now comes to bear laterally on the abutment roller 17. This situation is shown in dashed lines in FIG. 4, it is the pressure-relieved position of the valve body 9.
  • the system pressure here has dropped to, for example, 200 bar.
  • the restoring force on the valve body 9 only results from the effective cross-sectional area of the force transmission element 10. no longer from the effective cross-sectional area of the valve body blocking the valve seat 9.
  • the holding force with the valve body 9 open is already relatively low in this system. However, it can be reduced even further, to practically 0 N or even in the sense of self-retention.
  • the wedge gear connection 15 can be designed so that when the valve body 9 is open, it derives practically all of the restoring force caused by the force transmission element 10 into the stationary abutment.
  • the gear part, in particular the gear roller 16 is in contact with the abutment part, in particular with the abutment roller 17, that the contact point or the contact line is only slightly offset from the point of action or line of action of the Force transmission element 10 exerted restoring force on the abutment roller 17.
  • this angle tube 6 namely has a bearing bracket 19 which is attached to the angle tube 6, in particular welded on here. This has the advantage over the attachment to the gun housing 1 that the gun housing 1 can be kept free of forces.
