  "textContent": "The invention concerns a valve for controlling oil flow to a single sided cylinder having a single hydraulic connection comprising a valve housing (36) with a cylindrical wall enclosing a valve chamber (23), the cylindrical wall has a pump connection (4,46) to be connected to a pump, a cylinder connection (24,31) to be connected to the single hydraulic connection, and a tank connection (5,47) to be connected to a storage tank, a valve body (29) with ridges (30,32,34) that seal against the cylindrical wall of the valve chamber, a first channel (46,35,33,28,47) for connecting the tank connection and the pump connection and/or the cylinder connection, and a drive (17,40,43) for axially positioning the valve body in the valve chamber in a neutral position (N) wherein the valve body closes the cylinder connection and the first channel connects the pump connection and the tank connection, in a tip position (T) wherein the cylinder connection and the pump connection are connected and in a lower position (L) wherein the first channel connects the pump connection with both the cylinder connection and the tank connection. In accordance with the invention the first channel is formed by a cavity (33) in the valve body (29) and preferably by openings (28,35) at both ends in the sides of the valve body.",
