Abstract
An electromagnetically actuatable disc-type valve includes a pre-assembled hydraulic sub-assembly with a core member and a separately pre-assembled electrical sub-assembly with a body. The exterior surface of the core member is configured to facilitate insertion into the electrical sub-assembly and orientation relative thereto by use of a bushing. The outside diameter of the body of the valve is no more than 13.5 millimeters in the vicinity of the delivery end of the hydraulic sub-assembly. A fluid filter is disposed between a tensioning spring and a calibration slide to facilitate more accurate flow checking and leakage checking of the valve during manufacture.
