Abstract
An electromagnetic valve unit includes a yoke of magnetic metal. The yoke includes upper and lower walls that are integrally connected by side walls. A slit is provided by the upper wall of the yoke. The slit extends along a longitudinal axis of the yoke between axially opposed ends of the yoke. A plurality of electromagnetic valves are abreast installed in the yoke in such a manner that the yoke constitutes outside magnetic paths of solenoid coils of the valves. Each of the solenoid coils has terminal members that project outward from the yoke through the slit.

An electromagnetic valve unit comprising:
- a yoke of magnetic metal, the yoke comprising upper and lower walls that are integrally connected by side walls;
- a slit provided in the upper wall of the yoke, the slit extending along a longitudinal axis of the yoke between axially opposed ends of the yoke;
- and
- a plurality of electromagnetic valves abreast installed in the yoke in such a manner that the yoke constitutes outside magnetic paths of solenoid coils of the valves,
- wherein each solenoid coil has terminal members that project outward from the yoke through the slit,
- wherein the terminal members of every pair of the electromagnetic valves, which face each other with respect to the longitudinal axis of the yoke, are arranged close to one another and face one another,
- wherein the lower wall of the yoke comprises two axially extending wall portions that extend along the side walls respectively and a middle portion through which the two axially extending wall portions are integrally connected, and
- wherein the lower wall of the yoke is integrally formed with at least one strip that is angled relative to the lower wall, so that the strip exhibits a resiliency when pressed toward the lower wall, and
- wherein the strip extends axially outward from the middle portion of the lower wall of the yoke.
