<p>The invention relates to a slide valve for regulating the hydraulic pressure at a working connection (A) to values between a low pressure and a high pressure, for which purpose a valve slide (1) is accommodated in a hole (3) of a housing (4) such that it can move linearly, which housing (4) has a low pressure connection (T), a high pressure connection (P) and the working connection (A), for which purpose the working connection (A) is connected to the low pressure connection (T) in the first position of the valve slide (1), while the working connection (A) is separated from the two further connections (P, T) in a second position of the valve slide (1), and having a third position of the valve slide (1), in which the working connection (A) is connected to the high pressure connection (P). The invention provides for a plurality of radial holes (7) to be arranged in the valve slide (1), through which radial holes (7) flow can pass and which radial holes (7) interact with a plurality of circumferential control edges (6) in the housing (4) which seal the valve slide (1) in the hole (3) in a leakfree manner by means of suitable sealing rings (2).</p> |
