Pneumatic slide valve with split valve housing of plastic

A pneumatic slide valve, comprising:

• a valve housing defining an axis and made of injection-molded plastic material, said valve housing having a valve bore and a plurality of external ports, said valve housing including an outer housing portion, which is made of reinforced plastic and is determinative for a geometric outer dimension of the valve housing, and an inner housing portion, which is made of non-reinforced plastic and extends continuously within the valve housing to define a plurality of spaced-apart pressure fluid compartments in fluid communication with the ports and to define the valve bore at least in a region which is positioned in the area of the pressure fluid compartments, with the valve bore interrupted in axial direction by the pressure fluid compartments, wherein the outer housing portion is molded around the inner housing portion;
• and
• a slide member, accommodated in the valve bore of the valve housing for displacement in the direction of the axis, for regulating a flow of compressed air between the ports.
