  • Patent number: 5385396
    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.
    Type: Grant

  • Patent number: 5239133
    Abstract: A fitting arrangement and process for the guidance and the fixing of one or more electric lines passing into a cover lid, as far a valve block for electromagnetically switchable hydraulic valves. The lines are individually molded into a conductor accommodating element, which in turn is fit and sealed in an opening within the cover lid. The conductor accommodating element is retained in the cover lid opening by a protective cap having protrusions to lock the element in the opening, drawing a collar against the opposite side of the cover lid. The lines are bent over and exit an open end of the protective cap, which is locked in position by a ridge snapping into a depression in the cover lid as the cap is slid into grooves on the accommodating element.
