Valve block assembly

A valve block assembly comprising:

• a plurality of electromagnetically actuable hydraulic valves, each said valve defining at least one exposed electrical contact;
• a valve receiving member carrying said valves in a fixed array;
• a unitary cover matingly mounted to said valve receiving member in a fixed positional relationship therewith and co-acting therewith to sealingly enclose said valves;
• and
• an electrically conductive network insulatively carried by said cover and including a separate mating contact positionally aligned with each said valve contact for completion of an electrical circuit upon mounting of said cover upon said valve receiving member, an electrical interface operative to provide external access to said network, and electrical conductors stamped from a generally planar sheet of conductive material interconnecting said mating contacts and interface, whereby mounting of said cover upon said valve receiving member simultaneously establishes connection between all valve-mating contact pairs.

In a valve block assembly having at least one electromagnetically actuatable hydraulic valve means, block means for supporting said valve means, cover means for sealingly enclosing said valve means and power supply means for energizing said valve means, the improvement comprising:

• said at least one electromagnetically actuatable hydraulic valve means defining at least one positionally fixed exposed electrical contact;
• said cover means formed of an electrically insulative material and sealingly enclosing said valve means when matingly mounted to said block means in a fixed positional relationship;
• said power supply means including external connector means for electrically connecting power externally of said cover means, internal connector means for electrically connecting power internally of said cover means and conducting means for electrically interconnecting said internal connector means with said external connector means, said power supply means insulatively carried by said cover means and positionally fixed with respect to said cover means, said internal connector means including at least one mating contact positionally aligned with said at lest one exposed electrical contact of said valve means for completion of an electrical circuit when said cover means is mounted on said block means, at least a portion of said external connector means integrally formed as part of an external surface of said cover means, said internal connector means and said conducting means formed by stamping a generally planar sheet of conductive material.
