ABSTRACT:
A method of assembling elements into a valve block is described, especially for use with slip-controlled brake systems, in which a sealing ball, valve covers or valve seats are inserted into the valve block to be sealed without using force fitting, swaging or other mechanical working of the parts, to avoid contaminating abrasive particles generated by these processes. The elements are inserted into openings in the valve block housing with a clearance fit, and heated to a temperature higher than the austenite starting temperature causing a memory shape to be restored, which provides a sealing fixation of the elements in respective openings in the valve block.
