Definitions
- the invention relates to an electromagnetically operable valve, in particular for brake systems in motor vehicles, according to the preamble of claim 1.
- Such a valve is known from EP 1 307 369 B1.
- the known valve is arranged in a valve block as a switching element between a wheel brake cylinder and a fluid storage an ⁇ and serves to allow the wheel brake cylinder under pressure pending medium to flow in the direction of the fluid reservoir can.
- the inlet and the return bore for the pressure medium in the valve block and thus also in the valve are arranged perpendicular to the longitudinal axis of the valve.
- the inflow of the pressure medium from the Radbremszy ⁇ cylinder is perpendicular to the longitudinal axis of the plunger element.
- the pressure medium acts hydraulically in the same effective direction as a compression spring, which presses the plunger element in the direction of a sealing seat. It has been found that, in particular, the transition from the closed to the open valve or, conversely, due to the flow conditions, is associated with noises. As a result of the force of the pressure medium acting hydraulically in the same direction as the compression spring, it is not possible with the known magnetic circuit in the known valve to open the opening. To control the closing or closing operation of the valve in the desired manner to minimize the noise.
- the electromagnetically operable valve according to the invention in particular for brake power systems in motor vehicles, having the features of claim 1 has the advantage that the opening or closing operation of the valve can be controlled with relatively little effort as viewed from the magnet side.
- the proposed valve is furthermore compatible with the previous valve in terms of its connections, that is, the same valve blocks with the same geometry of the inlet or return bores for the pressure medium can be used.
- the valve element comprises a baffle surface, so that the fluid jet emerging from the sealing region no longer acts directly on the armature and the valve closing element.
- unwanted fluctuations in the hydraulic power can be reduced, which has a positive effect on the stability and controllability of the valve.
- FIG. 1 shows a longitudinal section through an electromagnetically actuatable valve which is arranged in a valve block
- FIG. 2 shows a section in the plane II-II of FIG. 1 in the region of the inlet bore, which cooperates with the valve seat
- FIG Longitudinal section through an alternative embodiment of an electromagnetically actuated valve.
- the electromagnetically actuatable valve 10 shown in FIG. 1 is partially arranged in or on a valve block 11 and forms part of a pressure control device, not shown otherwise, for a brake power plant of a motor vehicle.
- the normally closed valve 10 consists of two Bau ⁇ groups: a hydraulic part 13 which is partially received in a stepped bore 14 of the valve block 11, and an electrical part 15 which is unplugged on the upstanding from the valve block 11 hydraulic part 13.
- the electrical part 15 consists essentially of a bobbin 16 with an electrical winding 17, a magnetically-conductive coil jacket 18 and a magnet-flux-conducting annular disk 19.
- the hydraulic part 13 of the valve 10 has a guide sleeve 21 which, at its end assigned to the electrical part 15, is closed with a pressed-in and fluid-tight welded pole core 22.
- a longitudinally displaceable armature 23 is received in the guide sleeve 21, a longitudinally displaceable armature 23 is received.
- the armature 23 is supported by a return spring 24 on the pole core 22.
- Polkernabgewandt is in the anchor 23 in a bag Holes bore a substantially pin-shaped closure member 25 with a hemispherical end 26 is pressed.
- the guide sleeve 21 is connected by turning with a sleeve-shaped valve element 27.
- the valve element 27 has, on the side facing the armature 23, a funnel-shaped widened region 28, into which the armature 23 projects with its closing element 25.
- an annular space 29 is formed in the valve element 27 between the valve element 27 and the armature 23.
- a blind hole-like longitudinal bore 32 is formed in the longitudinal axis 31 of the valve 10, in which also the armature 23 and the valve element 27 are arranged, in the Ventil ⁇ element 27 on the closing member 25 side facing a blind hole-like longitudinal bore 32 is formed.
- the longitudinal bore 32 has in its outlet region a countersink 33, which forms a sealing seat together with the end 26 of the closing member 25 when the closing element 25 is pressed by the return spring 24 in the direction of the valve element 23.
- a transverse bore 35 From the bottom of the longitudinal bore 32 is a transverse bore 35, which leads to the outer periphery of the valve member 27.
- valve element 27 From the base 36 of the region 28 of the valve element 27 go from a plurality, in the embodiment four, arranged at equal angular intervals longitudinal bores 38 from.
- the longitudinal bores 38 open onto the side of the valve element 27 opposite the countersink 33.
- a filter element 40 is inserted in a bore 39.
- the valve element 27 described so far is preferably made of a sprayed or sintered metal, whereby there is the possibility er ⁇ to produce the valve element 27 without cutting.
- valve element 27 and the region of the guide sleeve 21 enclosing the valve element 27 are surrounded by an annular filter element 42.
- the filter element 42 can be flowed through by pressure medium, wherein a connection between the filter element 42 and the transverse bore 35 in the valve element 27 is made.
- valve 10 described so far is inserted with its valve element 27 and its filter element 42 into the stepped bore 14 of the valve block 11.
- an inlet bore 44 is provided, which is coupled to a wheel brake cylinder, for example.
- a drain hole 45 is arranged, which communicates via the filter element 40 with the longitudinal bores 38.
- the return spring 24 presses the closing member 25 against the counterbore 33 in the valve element 27, so that pressure medium is present via the inlet bore 44 and the filter element 42 in the transverse bore 35 and the longitudinal bore 32 can not escape via the sealing seat at the end 26 of the closing member 25.
- the fact that the pressure medium in the longitudinal bore 32 exerts a hydraulic force on the closing member 25, the ent ⁇ against the spring force of the return spring 24 acts, and thus supports the movement of the armature 23 at a current, can be with relatively small magnetic forces ge ⁇ targeted movement of the closing member 25 effect.
- the stroke can thus vary over the opening or closing time considered vary widely, depending on the specific application, the flow conditions on the valve 10 to make so that the lowest possible opening and closing operation of the valve 10 can be achieved.
- FIG. 3 corresponds substantially to that of Figure 1, but wherein the valve member 27 additionally has a in the radial direction in the space 29 extending baffle 49.
- the impact surface 49 has a hole in the center in which the closing member 25 is movably seated. Fluctuations in pressure and velocity of the free jet emerging after the valve seat lead directly to fluctuations in the hydraulic force (fluctuations as they are considered here can be caused for example by pressure surges or cavitation and are therefore unavoidable).
- the unwanted fluctuation in the hydraulic power disturbs the equilibrium of hydraulic force, magnetic force and spring force necessary for the stability of the valve 10. It comes to vibrations that lead to the loss of controllability in the worst case.
- the impact surface 49 absorbs these disturbances to a certain extent and thereby increases the robustness in the sense of a better controllability of the valve 10.
- the baffle 49 is configured such that it promotes the flow deflection down to the outflow channels 38. Untitled. This increases the flow through the valve 10 given a pressure difference.
- valve element 27 can preferably be produced without cutting from an injection or sintered metal, the shape is very variable. Design measures can be used in particular to optimize the flow guidance around armature 23 and closing member 25.
