Problems solved by technology

The disadvantage of this radial vibration is that it makes it difficult to regulate the pressure in pressure medium systems by electronic control of such valves
That is, radial vibrations adversely affect the pressure regulation accuracy of the valve

Embodiment Construction

[0014] figure 1 A solenoid-actuated valve 10 known from the prior art is shown in longitudinal section. The illustration of the solenoid coil which completes the valve 10 has been intentionally omitted for the sake of clarity. The valve 10 has a sleeve-shaped valve housing 12, in the figure 1 A plug-shaped pole core 14 made of magnetically permeable material is inserted into the open end of the upper middle part. The pole core 14 is fixedly connected to the valve housing 12 . The valve housing 12 is in figure 1 The open end of the lower middle part is closed by a seat body 16 which is also fixedly connected to the valve housing 12 . The seat body 16 forms a valve seat 18 which is arranged on the longitudinal axis X-X of the valve 10 and is formed on the base of a first flat depression 20 which is open towards the interior of the valve housing 12 . The valve seat 18 itself is configured, for example, in the shape of a conical seat. Opposite the flat depression 20 which is...

Abstract

The invention relates to an electromagnetically actuatable valve, in particular a pressure regulating valve of an antiskid controllable vehicle brake system. A known valve (10) of this type has a seat body (16) with a valve seat (18), at least one inflow channel (28) and an outflow channel (30). A blocking element (26) is provided in order to avoid a hydraulic short-circuit connection between the inflow channel (28) and the outflow channel (30) when the valve seat (18) is closed. According to the invention it is proposed that the blocking element (26.1, 26.2) is equipped with a flow guide (72.1, 72.2). The flow guiding mechanism (72.1, 72.2) prevents the partial flows from the inflow holes from merging with each other and directs the flow to the closing body (34) of the control valve seat (18), so that a transverse force is exerted on the closing body when it performs a lift movement . This transverse force deflects the closing body ( 34 ) in the radial direction during the opening or closing movement and thus produces a radial vibration damping effect which stabilizes the lift movement. Based on this effect, the valve (10) has better pressure regulation characteristics.

Description

technical field [0001] The invention relates to an electromagnetically actuatable valve, in particular a pressure regulating valve of a vehicle brake system with anti-skid control, comprising: a seat body forming a valve seat, which is correspondingly provided with at least one inflow channel for introducing a pressure medium and an outflow channel from which pressure medium emerges; a blocking element which interrupts the hydraulic short-circuit connection between the inflow channel and the outflow channel. Such a valve is known, for example, from DE 10 2010 002 469 A1 or DE 10 2011 079 339 A1 with regard to its design. The valve has a seat body which, in addition to forming the valve seat, also forms at least one inlet channel through which the pressure medium is conducted and an outlet channel through which the pressure medium is discharged. In order to avoid a hydraulic short circuit between these channels when the valve seat is closed, a blocking element is provided. In...
