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.

[ What is claimed is:] [1.] An electromagnetically actuatable disc-type valve for metering the supply of fluid, the valve comprising:an elongated cylindrical core member having an exterior surface including a bottom surface, said core member defining a hollow passage internally thereof;an armature having a top surface disposed toward said bottom surface of said core member, said armature having a bottom surface disposed to face opposite said top surface of said armature;a lift stop member formed of non-magnetic material, said lift stop member being configured in the form of a first annular sleeve with an axial opening configured to receive a portion of said core member therein;a valve seat configured in the form of a first disc having a top face disposed toward said bottom surface of said armature, said top face including a top surface, said valve seat defining at least one entrance opening through said top surface, said valve seat defining at least one sealing land surrounding all said entrance openings and having an upper surface raised above said top surface of said valve seat;a nozzle pole configured in the form of a second annular sleeve, said nozzle pole defining a supply end and a delivery end disposed axially opposite said supply end, said nozzle pole defining an interior wall at said supply end, at least part of said interior wall defining at least part of a first receiving compartment, said armature being at least partially received within said first receiving compartment;each of said core member, armature and nozzle pole being formed of magnetic material and configured and disposed together to be selectively actuated to form part of a magnetic circuit with a single working pole at said bottom surface of said core member;a guide ring formed of non-magnetic material and configured in the form of a third annular sleeve, said guide ring being disposed to prevent physical contact between said armature and said nozzle pole when said core member, said armature and said nozzle pole are selectively actuated to form part of said magnetic circuit;a first weld for welding said nozzle pole to said lift stop member; anda second weld for welding said lift stop member to a portion of said exterior surface of said core member in a manner defining an air gap of a predetermined magnitude between said top surface of said armature and said bottom surface of said core member when said core member, said armature, and said nozzle pole are selectively actuated to form part of said magnetic circuit.
