<p>There is a slide valve for a fluid, in which a piston slide (3) in a housing chamber (2) of a valve housing (1) can move axially in a reciprocating manner, in which, in the valve housing (1), a housing channel (7) connected to a first connection (8) is provided with a through-flow opening facing the piston slide (3) and in which, in the piston slide (3) a slide channel (14), connected to a second connection (11), is provided with a through-flow opening facing the valve housing (1). In this arrangement, it is desired that the slide valve, in which flow stoppages resulting from fluid impurities do not occur, is designed such that the flow control can be carried out in a more finely sensing manner. This is achieved in that the outlet-side through-flow opening extends over a cut-out (16) originating from the associated channel (14), the cross-section of which cut-out (16) tapers in the axial direction towards the inlet-side through-flow opening when the piston slide (3) is in the blocked position. For flow control in the slide valve, not only is the overlapping region of the two through-flow openings moved but moving the piston slide also changes the cross-section available for the fluid to flow out of after passing through the overlapping region. …<IMAGE>… </p> |
