Disclosed is a continuously adjustable spool valve comprising an inner bushing (2), which serves as the valve spool, and comprising an outer bushing (4) fixed to the housing, which is surrounded by two annular spaces (10, 12). In order to adjust the flow cross-section between the two annular spaces, a plurality of slots (18) are provided in the inner bushing and in the bushing fixed to the housing, which slots extend in the circumferential direction of the bushings and are axially spaced with respect to each other. When the inner bushing (2) is displaced, the slots can be simultaneously covered and the connection is hence pushed shut or enlarged in the overlap thereof and the connection is thus opened. |
