Abstract
A valve assembly, in particular for a hydraulic vehicle brake system with traction control, having at least one, preferably electromagnetically actuatable valve, which receives valve components in a valve housing and is retained by fastening means by nonpositive and/or positive engagement in a receiving bore of a valve block. The valve block, at least in the region of the receiving bore, comprises thermoplastic, and the fastening means have at least one retracted region on the radially outer circumference of the valve housing or of a valve holder that retains the valve housing in the receiving bore, into which region plastic rendered molten by heating and ensuing insertion of the valve and/or of the valve holder into the receiving bore can flow, and after cooling of the thermally deformed plastic a positive-engagement connection can develop between the valve housing and the receiving bore or the valve holder and the receiving bore.
