Patent ID: 7137411

Claim:
An electromagnetic hydraulic valve with following features: the hydraulic valve comprising an electromagnet comprising an axially movable armature, a valve part comprising at least two valve seats and a closing ball corresponding to at least one of the valve seats, the electromagnet is formed by a hollow cylindrical plastic coil spool comprising an electric plug contact, at least one coil winding received in the coil spool and a magnet housing surrounding the coil winding, the magnet housing is configured as a cylinder tube sleeve whose one end is angled into an interior of the sleeve to form a circular ring-shaped bottom and whose other end comprises a plurality of turn-over tabs for connecting the magnet housing to the coil spool, a hollow cylinder of the plastic coil spool is configured at least partially as an armature space for the armature, into which armature space an upper pole and a lower pole of the electromagnet extend and which is lined with a non-magnetic metal sleeve, the valve part is formed by a hollow cylindrical valve housing that comprises a pressure delivery connection (P) on one front end, as well as a load connection (A) and a tank connection (T) that are made as radial holes in a cylinder jacket of the valve housing, inside a hollow cylinder of the valve housing is arranged respectively between the pressure delivery connection (P) and the load connection (A), and between the load connection (A) and the tank connection (T), one of the valve seats of the valve part, the valve seats of the valve part are made as axial apertures in bottoms of two cup-shaped deep-drawn parts that are fixed with peripheral surfaces in the hollow cylinder of the valve housing by a press fit, the hydraulic valve can be inserted with the valve part that comprises at least one outer sealing ring into a complementary valve reception, and the hydraulic valve comprises a fixing flange through which the hydraulic valve can be screwed, pressure-medium tight, on the valve reception, wherein at least one of the valve housing of the valve part and the lower pole of the electromagnet is configured as a separate part that can be made without chip removal, and the lower pole is made integrally in one piece with the fixing flange of the hydraulic valve and also serves as a reception socket for the valve housing.
