Abstract
A valve block, in particular for slip-controlled hydraulic brake systems, includes a plurality of valve domes (10) incorporating magnet coils (1) and insulating casings cast around the magnet coils (1), as well as a contact carrier (2) containing a plurality of electric conductors (4), with the insulating material (10) encompassing the magnet coils (1) forming an integral unit with the contact carrier (2). The resulting design improves manufacturability, functional reliability, modular design flexibility and serviceability.
Claims14
A valve block for slip-controlled hydraulic brake systems comprising:
- a plurality of valve domes incorporating magnet coils with insulating material cast around the magnet coils;
- and a contract carrier containing a plurality of electric conductors, wherein the insulating material encompassing the magnet coils forms an integral unit with the contact carrier wherein the contact carrier is interconnected with the insulating material of the magnet coils by at least one elastic linkage whereby said interconnection is substantially independent of fit tolerances and temperature variations.
A valve block comprising:
- a valve block housing;
- a plurality of valve domes carried on said housing;
- a coil concentrically disposed about each said valve dome, each said coil encased within insulating material;
- a contact carrier composed substantially of insulating material integrally formed with said coil insulating material and containing a plurality of electric conductors interconnecting said coils with at least one circuit interface,
- wherein at least of said coils is disposed in a spaced relationship with said contact carrier and at least one of said electric conductors resiliently bridges the two, and
- wherein said bridging electric conductor is insulatively substantially encased within elastomeric linkage interconnecting said coil and contact carrier.
