Abstract

A valve control device of the kind used in ABS or ASR systems as applied in motor vehicles. Such a valve control device comprises a valve block that accommodates the solenoid valves and where a solenoid is assigned to each solenoid valve. The side of a solenoid holder facing the valve block has compartments for accommodating the solenoids, there being an elastic spring element on its compartment base that presses the solenoid against the valve block. Furthermore, each solenoid has first media that, when the solenoid is introduced into this compartment, act together with second media, assigned to the compartment, as a snap latch in such a way as to prevent the solenoid from being pulled out from this compartment. The first and second media are sufficiently elastic that the solenoid can still be moved slightly in all directions in the plane perpendicular to its coil axis.

Dependent claims

Valve control device for controlling a hydraulic/pneumatic system including several solenoid valves arranged in a valve block, with each such valve having a solenoid assigned to it and being arranged in a coil holder having a side facing away from the valve block and a side facing the valve block, and wherein:

a) a printed circuit board is provided and situated on the side of the coil holder facing away from the valve block and holding a control electronics system;
b) the side of the coil holder facing the valve block has coil compartments to accommodate the solenoids, with the depth of these compartments corresponding approximately to the length of the respective solenoids;
c) between each solenoid and the associated coil compartment base there is an elastic spring element that presses the solenoid against the valve block;
d) each solenoid has first media that act together with a second medium assigned to the coil compartment to provide a snap latch function on introducing the solenoid into the coil compartment such that the solenoid is prevented from being pulled out of the coil compartment;
and
e) the first and the second media are sufficiently elastic that the solenoid can still be moved slightly in all directions in the plane perpendicular to its coil axis.
