Abstract
A sliding valve having a valve slider that can be axially displaced relative to the valve sleeve in order to determine the size of variable passage cross-sections and for establishing a pressurization connection between a high-pressure connection and a working connection and a pressure-reducing connection between the working connection and a low-pressure connection, in that control edges running in the circumferential direction are configured on the outer circumference of the valve slider, which interact with the control edges of the valve sleeve. The control edges of the valve sleeve are configured as edges extending in the circumferential direction relative to the symmetry axis, which are a component of a lateral face of the valve sleeve.
