Abstract

In its housing bore (22), the circular slide valve has a sealed sleeve (35) which is inserted such that it can rotate and/or move axially. The sleeve (35) is externally adjustable by means of an adjusting projection (41). Depending on the setting of the sleeve (35), the inner end of the sleeve (35) may cover to a greater or lesser extent the opening (10) of an air supply channel (5) into the housing bore (22), as a result of which its flow cross-section is adjustable. The circular slide (23) is supported in a sealed manner such that it can move in the housing bore (22) and the sleeve (35) in the normal manner. Restrictor devices of such a type for channel openings can be provided on both ends. In the case of a 5/2-way valve which is used for controlling the application of pressure to a double-acting cylinder, the outlets can in this way be designed in a simple manner to be adjustable. <IMAGE>
