ABSTRACT:
A spool valve having a valve housing with an internal spool receiving space, in which a valve spool is arranged. A plurality of sealing rings are arranged in axial sequence. Such sealing rings are retained in holding recesses, which are formed integrally with the valve housing. The valve housing is itself longitudinally divided and is composed of a plurality of housing parts which respectively constitute a wall section, extending for some distance in the peripheral direction, of the spool receiving space including the associated peripheral sections of the holding recesses. It is in this manner that the sealing rings may be inserted into the spool receiving space without any difficulty in the separated condition of the housing parts, whereafter the housing parts only have to be fitted together.
