Definitions
- Valve arrangement in particular electromagnetic valve arrangement for slip-controlled motor vehicle brake systems
- the invention relates to a valve arrangement, in particular an electromagnetic valve arrangement for slip-controlled motor vehicle brake systems according to the preamble of claim 1.
- FIG. 1 is a plan view of the check valve shown in FIG. 1,
- Fig. 3 shows an alternative embodiment for the arrangement of a check valve in the valve receiving body.
- valve 1 shows, on a considerably enlarged scale, a section of a valve arrangement consisting of a rotationally symmetrical valve housing 12, in the valve receiving bore 8 of which a disk-shaped valve seat body 4 and a disk-shaped check valve 1 are fastened.
- the fastening of both parts can preferably be done by caulking the valve housing 12, wherein in the present exemplary embodiment the caulking of the housing material of the valve seat body 4 presses the check valve 1 against a step of the valve receiving bore 8.
- 1 shows the closed position of the check valve 1, in which the sealing surface 6 facing the valve seat body 4 closes the bypass openings 5 in the valve seat body 4 over the entire surface.
- valve closing member 7 is located on the side facing away from the check valve 1 on the valve seat body 4 and closes the opening in the event of electromagnetic excitation 3, which is bypassed at a corresponding hydraulic pressure difference at the check valve 1 by the sealing surface 6 lifts off the bypass openings 5.
- a pressure medium connection between the pressure chambers located above and below the valve seat body 4 is then made possible via the central passage opening 2 as well as along the slot 11 in the check valve 1.
- FIG. 2 shows, with reference to FIG. 1, only the check valve 1 according to the invention in a plan view, so that the slot 11 which can initially only be seen as a bore in the check valve 1 in FIG. 1 can now be clearly recognized as an opening running in the form of a segment of a circle.
- an elastic, web-shaped section 10 extends, which connects the central section to the fastening ring 9.
- the check valve 1 thus has a first outer section which acts as a fastening ring 9 and which is connected via the elastic second web-shaped section 10 to the central section having the sealing surface 6.
- This center section acts as it were via the elastic web-shaped section 10 as a spring tongue in order to lift off the end face of the valve seat body 4 as required due to a hydraulic force acting on it.
- the check valve 1 shown as a plate check valve is preferably made of spring steel or a comparable, heat-treated sheet. However, it is also conceivable to use other alternative materials with corresponding spring properties.
- FIGS. 3 shows an alternative arrangement and embodiment of the check valve 1, which essentially has a disk-shaped sealing surface 6, which is guided axially movably with its entire surface between the valve seat body 4 and the end region of the valve receiving bore 8 in the valve housing 12.
- its disc diameter is selected to be correspondingly smaller than the diameter of the valve receiving bore 8.
- the check valve 1 is in the operating rest position under the action of gravity either on the ring end section 13 of the valve receiving bore 8 shown in the illustration on, or with a hanging valve arrangement on the valve seat body 4. Since this check valve 1 is also shown in FIGS.
- FIG. 4 shows an embodiment of the invention that has been further improved compared to FIG. 3.
- the plate-shaped check valve 1 has the design known from FIG. 3.
- the valve seat body 4 is also identical to the construction shown in FIG. 3. It should be noted that the check valve 1 can be manufactured with a face-turned and slide-ground surface machining process instead of an etched, rustproof and flat ground spring steel.
- the valve seat body 4 has a shoulder 14 to facilitate assembly.
- radial grooves 15 are directed onto the pressure medium channel, which favor the closing speed of the check valve 1, particularly in the cold.
- the present construction of the check valve 1 is particularly well suited for receiving an orifice function, since a precise small hole can be etched into the plate structure without any problems.
- the check valve 1 is designed as a plate check valve which has a passage opening 2 which is aligned coaxially with a first opening 3 of the valve seat body 4, with at least one bypass opening for the first opening 3 in the valve seat body 4 5 is arranged, which is either closed or released by a sealing surface 6 located laterally to the passage opening 2 of the check valve 1.
- the check valve 1 is arranged on the end face of the valve seat body 4 which is remote from the electromagnetically actuable valve closing member 7 and at least in sections is axially movable between the valve seat body 4 and a step of the valve receiving bore 8 with its sealing surface 6.
