Definitions

  • the invention relates to a pressure regulating valve, in particular for regulating the hydraulic pressure in a motor vehicle transmission, according to the preamble of patent claim 1.

  • FIG. 2 shows a second expedient embodiment of the invention shown on a pressure control valve, the inlet channel of which in the basic position of the spherical valve closing element is connected on the one hand to the outlet channel and on the other hand is separated from the leakage channel,
  • FIG. 3 shows a modification of individual features of the pressure control valve according to FIG. 1,
  • FIG. 4 shows a modification * of individual features of the pressure control valve according to FIG. 2.
  • Each of the two pressure regulating valves has a valve housing 8, 9 manufactured in a cartridge design, in which a valve tappet 6 is guided, which cooperates with a first spherical valve closing member 13, around the flow path between a first pressure medium connection 1 (inlet channel, which opens radially into the valve housing 8, 9) ) and a second pressure medium connection 2 (drainage channel) which opens axially from below into the valve housing, either to interrupt or to connect.
  • the valve housing 8, 9 accommodates a valve seat 4 facing the first valve closing member 13 and a magnet armature 14 which actuates the valve tappet 6 and which is movably arranged within a valve coil 20 arranged on the valve housing 8, 9.
  • each of the two pressure control valves is constructed in such a way that the valve seat body 5 by means of a centering body 7 guiding the valve tappet 6 in the valve housing 8 , 9 is fixed.
  • the centering body 7 is preferably held in the valve housing 8, 9 by means of a press connection that is particularly simple to implement.
  • a passage 12 is arranged in the center of the centering body 7, through which the valve tappet 6 extends, for which purpose the pocket-shaped recess of the centering body 7 has two punched holes which can be closed by a further valve closing member 27 fastened to the valve tappet 6.
  • the surface of the cap-shaped centering body 7 facing the further valve closing member 27 therefore has a valve seat surface 10 adapted to the contour of the further valve closing member 27 to accommodate the further valve closing member 27 in order to make the pressure medium connection between the two pressure medium channels 1, 2 and the third pressure medium connection 3 dependent on that To be able to separate the position of the valve lifter 6 at any time.
  • the second Ventilschüeßgüed 13 is designed as a plate-shaped seat valve, which is preferably produced by stamping, embossing or deep-drawing thin sheet metal to form an annular disk which is attached to the valve tappet 6 by means of a press fit.
  • the valve housing In order to be able to manufacture the valve housing as small as possible and inexpensively, it consists of a first and a second housing part 8, 9, the first housing part 8 being designed as a deep-drawn housing pot into which the valve seat body 5 and the centering body 7 are pressed.
  • the first housing part 8 is fastened to the collar 15 of the second housing part 9 in a particularly simple manner in a pressure-tight manner by means of a press connection, the second housing part 9 being designed as a tubular cold extrusion or turned part for receiving the parts relevant for the magnetic circuit (magnet armature 14, valve coil 20).
  • the magnet armature 14 is designed as a hollow igniter, into which a magnet armature sleeve 16, which is produced in the deep-drawing process, is pressed and which projects with its sleeve ends on both sides of the end faces of the magnet armature 14.
  • the lower sleeve end has a stop 17 for the valve tappet 6, while on the side of the stop 17 facing away from the valve tappet 6, a compression spring 18 arranged inside the magnet armature sleeve 16 is accommodated in a space-saving manner and is acted upon by an adjusting sleeve 21 adjusted in the yoke ring 19.
  • the yoke ring 19 consists of a sheet metal part produced in the deep-drawing process, which is placed over the outer circumference of the valve coil 20.
  • the yoke ring 19 is bent with its end facing away from the valve housing 9 inwards around the upper edge of the valve coil 20 and is connected by means of a press connection to a tube 22 which, with its end remote from the offset region, extends between the valve coil 20 and the magnet armature 14 in the direction of the End face of the second housing part 9 extends.
  • the tube 22, following its press-fit area in the yoke ring 19 has a step section (23) with an enlarged diameter, on which the magnet armature sleeve (16) is supported.
  • a filter bowl 24 provided with a ring filter fabric is pressed onto the first housing part 8, a pin 25 being arranged at the bottom of the filter bowl 24, which pin closes a stepped bore 26 arranged in the center of the valve seat body 5, in which the first valve plug 13 is inserted.
  • a transverse channel 28 opens into the stepped bore 26 and is permanently connected to the first pressure medium connection 1 opening radially into the wall of the first housing part 8.
  • the second pressure medium connection 2 extends as a longitudinal channel eccentrically through the bottom of the filter bowl 24 and through the bottom of the valve seat body 5 into the cavity of the first housing part 8, in which the centering body 7 is located and from there (depending on the position of the two Ventilschüeßgüeder 13, 27) with the first and / or connected to the third pressure medium connection 1, 3.
  • the filter bowl 24 is made of a plastic, which has circumferential grooves at both ends, into which sealing rings 30 are inserted, which lie sealingly along the bore wall of a valve carrier 31 receiving the pressure regulating valve.
  • the cup-shaped housing part 8 On the upper edge of the valve carrier 31, the cup-shaped housing part 8 is supported with its radially outwardly bent edge, on which a projection of the second housing part 9 holds the pressure control valve in the valve carrier 31 under the action of an axial assembly force.
  • the spherical first valve closing element 13 is in the electromagnetically non-energized basic position of the armature 14 in its closed position on the valve seat 4, since a return spring 29 is arranged between the cup-shaped stop 17 and the second housing part 9, the force of which is greater is the counteracting force of the compression spring 18.
  • the further plate-shaped valve closing member 27 is lifted off the valve seat surface 10, so that the second pressure medium connection 2 is connected exclusively to the third pressure medium connection 3 through the longitudinal channel of the valve seat body 5.
  • the tube 22 in the valve construction according to FIG. 2 additionally takes on the function of the magnetic core, as a result of which an incredibly simple structure of the magnetic core is realized.
  • the pressure regulating valve according to FIG. 3 differs from the pressure regulating valve according to FIG. 1 by a yoke ring 19 which is pulled down particularly deep in the interior of the valve coil 20 in the direction of the valve housing 9 and in which the magnet armature 14 is guided.
  • the tube 22 with a constant diameter can be designed particularly easily as a cold-drawn or deep-drawn part.
  • the pressure regulating valve according to FIG. 3 differs from the pressure regulating valve according to FIG. 1 by the one-piece design of the magnet armature sleeve 16 with the stop.
  • the further illustrated features of the pressure control valve according to FIG. 3 can be found in the description part of FIG. 1.
  • the pressure regulating valve according to FIG. 4 differs from the pressure regulating valve according to FIG. 2 by a yoke ring 19 which is drawn lower in the inner region of the valve coil 20 in the direction of the valve housing 9 and in which the magnet armature 14 is guided in the upper end region.
