Definitions
- the invention relates to a pressure regulating valve having a housing that has a coil wound on a coil carrier, an axially displaceable in a bearing armature, a core and a flux guide, and that has a connection bore and a connection piece, wherein the connection piece has a valve seat for the armature ,
- Such pressure control valves are pump used in particular in hydraulic actuators, in controls for automotive automatic transmission or in combination with a pressure or flow rate controlled engine oil. These may be so-called on / off valves, or so-called modulator valves, which can infinitely control a throughput.
- an on / off control valve is here to be listed, which is known from DE 197 16 185 A1.
- an electromagnetically driven armature cooperates with a valve seat to fluidly connect a connection opening with a drainage hole.
- the armature cooperates with compression springs and the electromagnetic drive such that a sealed closure is ensured in the off position.
- high demands are placed on the electromagnetic drive and the manufacturing accuracy of the pressure control valve, which naturally leads to a high manufacturing and assembly costs.
- the invention is therefore an object of the invention to provide a pressure control valve, which ensures its functionality with the lowest possible production and assembly costs.
- the housing is designed substantially in two parts, wherein a lower part of the connecting piece and the connection bore, and is non-positively or positively disposed in an upper part of the housing, wherein in the direction of the core parts of the connecting piece a bearing bush is provided for the anchor and in the opposite part of the connecting piece a stop bushing is provided for the anchor.
- the pressure control valve in terms of tolerance and manufacturing accuracy is particularly simple and inexpensive to produce.
- the lower part has a through hole in which the bearing bush and the stop bushing are non-positively or positively arranged, the lower part is particularly inexpensive to produce and thus avoids easily alignment inaccuracies between bearing and stop bushing.
- the bearing bush is set back in relation to the connection bore in the lower part, a high pressure medium throughput via the connection bore can be realized in a simple manner even with a small armature stroke.
- the penetration depth of the stop bushing is adjustable in the lower part, such that the stroke of the armature is adjustable. This can be ensured for example by the fact that the stop bushing is pressed into the lower part and has a knurling, cording or the like, so that the adjustment of the stop bushing can be made easily and accurately.
- the directed towards the lower end of the armature can be bevelled at an angle ⁇ and be directed to the armature end of the stop sleeve at an angle ß beveled such that there is a line contact between the armature and the stop bushing.
- the core has a pin made of a non-magnetizable material which acts as a stop element for the armature and as a spring seat for a spring which supports the armature resiliently relative to the core.
- the pin can be arranged adjustably in the core.
- the some figure shows a sectional view of a preferred embodiment of a pressure regulating valve.
- the control valve 1 comprises a housing 2, which is designed substantially in two parts.
- the upper part 3 has an electromagnetic drive unit 4 which acts on an armature 6, which is arranged axially displaceably in a bearing 5.
- the electromagnetic drive 4 consists essentially of a coil 7, a core 8, and a Flußleit Tout, the
- the executed in plastic housing also has a plug 11 for controlling the pressure control valve.
- the core 8 is clipped in the present case in the upper part 3.
- the electromagnetic drive 4 acts on the armature 6, which in the present case
- the armature 6 serves as a valve rod and valve closure member of an on-off valve.
- the armature 6 is biased by a spring 12 relative to the core 8 in a closed position.
- the spring 12 is guided by a pin 13 in the
- Assembled state adjustable in the core is arranged and at the same time as upper
- Stop element for the armature 6 is used.
- the armature 6 is in turn in a here as
- the bearing bush can consist in particular of a magnetizable steel carrier plate and a non-magnetizable sliding layer, for example of bronze or Teflon.
- the thickness ratio between the beam carrier plate and sliding layer is approximately
- This bushing 5 is in one
- Lower part 14 arranged in the upper part 3 of the housing 2 non-positive or positive is arranged.
- This lower part 14 also has a connecting piece 15, which serves in the present case, the supply of a pressure medium and has a connection bore 16 through which the pressure medium can be forwarded.
- a stop bushing 17 is provided, which forms the valve seat for the armature 6.
- the directed towards the lower part 14 end of the armature 6 is angled ⁇ at an angle and the armature 6 directed end of the stop bushing 16 beveled at an angle ß. Due to the unequal angle results in a line contact of the armature 6 on the stop bushing 16, which has a good sealing effect.
- the line seal can be ensured by a so-called "striking.”
- the stop bushing 16 has a knurling, not shown, which makes it possible to precisely adjust the penetration depth of the stop bushing 16 and thus to limit the stroke of the armature 6.
- connection bore 16 In order to achieve a full-surface flow through the connection bore 16 to flow through the pressure medium from the connecting piece 17 to the connection bore 16, the bearing 5 is slightly offset relative to the connection bore 16 in the lower part 15, whereby the free space corresponding to the bearing thickness forms a flow zone which forms the entire surface Flow through the connection hole 16 allows.
- the armature 6 west further on an inner bore 18, which ensures a pressure equalization via the armature 6. Due to the design of the armature 6 and the fact that above the armature 6, the same pressure as below the armature 6 prevails, the armature 6 itself is pressure balanced. In this way, the electromagnetic drive 4 can be made simpler and less expensive.
- the illustrated pressure control valve 1 can be used in particular as a control valve for a controllable mechanical oil pump in which the oil flow rate is to be controlled by this pressure control valve. If now the oil pressure of the oil pump can be reduced, the electromagnetic drive 4 is actuated and thus the armature 6 is moved in the direction of the core 8. Thus, the oil can be performed via the inlet of the connecting piece 15 to the connection bore 16 and from there out of pressure in an oil pan, not shown.
