Abstract
A spool valve possesses a longitudinally divided valve housing, in the case of which housing parts are assembled with longitudinal sides fitted together. In the wall of the valve housing valve ducts are provided. In order to enable simplification of the manufacture of such valve housings at least part of the length of a valve duct extends in the parting interface of the valve housing. In this respect the wall of the valve duct is made up of complementary peripheral wall portion, which are provided at the housing parts adjacent to each other in the parting interface.
