Definitions

  • the invention is based on a solenoid valve according to the preamble of the main claim.
  • a solenoid valve of this type has become known, in which the disk-shaped stop part of the valve closing member comes into contact with an annular bead of the fixed stop when opening, which has a breakthrough coaxial to the annular bead.
  • the valve closing member strikes hard on the annular bead, so that rebounding disturbing the liquid flow occurs.
  • there are hydraulic adhesive forces which differ from valve to valve. Rebounders and adhesive forces have a very unfavorable effect on the switching times of the valves from stroke to stroke and from valve to valve. This is particularly disadvantageous when such a valve is used for the metering of fuel per injection stroke of a fuel injection pump or per fuel supply cycle and the metering accuracy required.
  • the solenoid valve according to the invention with the characterizing features of the main claim has the advantage that a squeezing flow in the opening gap between the damping chamber and the closing surface results in a damping of the opening movement of the valve closing member and that the adhesive forces when reopening the damping chamber are very low. Furthermore, it has been found to be advantageous that the function of the solenoid valve is much less temperature-dependent due to the narrow stop surface of the damping chamber than in known solenoid valves, since a turbulent squeezing flow occurs in the damping gap when the damping chamber is closed.
  • FIG. 1 shows a first exemplary embodiment of a solenoid valve in longitudinal section
  • FIGS. 2 and 3 show the part of a second and third exemplary embodiment essential to the invention in longitudinal section.
  • the solenoid valve has a valve housing 1, in which a core 2 made of ferromagnetic material is inserted, which carries a solenoid 3 between an inner cylinder 4 and an outer cylinder 5.
  • Inner cylinder 4 and outer cylinder 5 are connected to one another in a magnetically conductive manner by a yoke 6.
  • a magnetically conductive yoke plate 7 covers the outer cylinder 5 and the magnet coil 3.
  • the magnetic circuit interrupted between the inner cylinder 4 and the perforated plate 7 is bridged by an armature 10.
  • the armature 10 has a plate-shaped part 11 which merges into a hollow cylindrical connecting piece 12 which lies opposite the end face of the inner cylinder 4 and which engages through an opening 9 in the plate 7.
  • Two guide collars 18, 19 guide the valve closing part 15 in a cylinder bore 20 of a guide bushing 21.
  • the guide bushing 21 is part of a valve seat body 22 which has an inflow bore 23 in extension to the cylinder bore 20.
  • a cavity 24 is enclosed by the yoke 6 and valve seat body 22, from which drain bores 25 extend.
  • a conical valve seat 27 is formed in the valve seat body 22, with which a hemispherical closing body 28 of the valve closing part 15 cooperates. Bores 29 in the guide bushing 21 connect the cavity 24 and the annular chamber 26.
  • the drain bores 25 lead through an intermediate chamber 30 to a return flow channel 31 in the valve housing 1.
  • a return spring 35 is supported in the upper part of the guide bushing 21, which rests with its upper end on the armature head 16 of the valve closing part 15 and, in the non-excited state of the solenoid coil 3, lifts the valve closing part 15 from the valve seat 27 and counteracts it presses a stop plate 36 fixedly arranged above the armature 10 and the plate 7, so that the solenoid valve is in the open position.
  • fluid for example liquid fuel
  • inflow bore 23 under high pressure, which is connected to the pressure chamber of a fuel delivery pump of a fuel injection system for internal combustion engines.
  • return flow channel 31 is connected to the low-pressure suction side of the fuel feed pump.
  • a damping chamber 40 which is open against the disc-shaped armature head 16 is arranged on the stop plate 36.
  • the ceiling of the damping chamber 40 is formed by the plate itself and the side wall by an annular collar 41 projecting downward from the stop plate 36.
  • the thickness of the wall of the collar 41 is very small, so that the end-face, annular stop surface 42 for the anchor head 16 is very narrow.
  • the stop surface 42 is preferably spherical in order to keep the hydraulic adhesive forces low when the anchor head 16 is lifted off the stop surface 42.
  • this chamber 40 is in the stop by a throttle bore 43 plate 36 connected to the space 44 above the stop plate 36, which is also under low pressure.
  • the throttle bore 43 is dimensioned such that when the anchor head 16 strikes the stop face 42 of the annular collar 41, the flow rate is negligibly small, so that the damping chamber 40 has a damping effect, but that fluid is removed from the chamber when the anchor head 16 is lifted off the annular collar 41 44 can flow into the damping chamber 40.
  • this throttle bore 43 a damping effect of the damping chamber 40 is ensured since the valve closing part 15 has a high speed before striking the annular collar 41, but has a low speed when it is lifted off.
  • a throttle in the form of a fine channel can be provided in the stop surface 42 of the annular collar 41 or in the surface of the anchor head 16 which comes into contact therewith.
  • a plurality of openings 45 are arranged in the armature head 16, evenly distributed, through which displaced fluid can flow.
  • the arrangement of these openings 45 is preferably such that they coincide with the radially outer part of the stop surface 42 of the collar 41. This results in a further reduction in hydraulic gluing when lifting off the anchor head.
  • the solenoid valve opens again if the pressure in the pressure chamber of the connected fuel delivery pump is to be reduced.
  • the circuit to the magnetic coil 3 is interrupted again with the effect that the holding force of the core 2 is eliminated.
  • the valve closing part 15 is displaced upwards at a relatively high speed.
  • the anchor head 16 strikes the stop surface 42 of the collar 4j between the stop surface 42 and the ring region of the upper side of the armature head 16 which coincides therewith, a squeezing flow from the damping chamber 40 and the space which coincides downwards with this.
  • FIGS. 2 and 3 are modified compared to the one described above according to FIG. 1 only with regard to the damping device.
  • the same reference numerals are therefore used for parts that remain the same and have the same effect.
  • a check valve 50 is provided which allows fluid to flow from the upper space 44 into the damping chamber 40, but blocks in the opposite direction.
  • the check valve 50 consists of a recess 51 covering the damping chamber 40 and an opening 52 coaxial therewith with a smaller diameter, and of a ball 53 in the recess 51 against the opening 52, which is supported by a conical compression spring 54 against the seat on Transition between the recess 51 to the opening 52 rests.
  • the compression spring 54 is supported on a snap ring 55.
  • the check valve 50 has the advantage that when the anchor head 16 is lifted from the stop surface 42, fluid flows from the chamber 44 into the damping chamber 40 without resistance, whereas when the anchor head 16 approaches when the solenoid valve is opened, no fluid flows from the damping chamber 40 into the chamber 44 can flow, but, as described above, displaced fluid is used to dampen the approach movement.
  • the damping chamber 40 is enlarged in that the valve closing part 15 has a blind bore 60 which is open at the top.
  • a throttle bore 61 is arranged in the lower part of the valve closing part 15, which connects the blind bore 60 with the annular chamber 26.
  • the damping chamber and its narrow stop surface can also be arranged on the valve closing part 15 or on its anchor head 16 instead of on the stop plate 36.
