摘要： The invention concerns a valve arrangement (7) comprising a flow path (11) connecting an inlet (9) and an outlet (10), a closing means (12) arranged in said flow path (11), a resetting means and a first pressure in a first pressure chamber (14) acting in a closing direction on said closing means (12), a pressure of said outlet (10) and a second pressure in a second pressure chamber (18) corresponding to a pressure of said inlet (9) when said closing means (12) is closed acting in opening direction on said closing means (12), said first pressure chamber (14) being connectable to the outlet (10) via an auxiliary valve (13). It is intended to keep small a pressure pulse when opening the valve arrangement (7). This is achieved in that the closing means (12) having a first opening state (A) and a second opening state (B), a flow resistance of said closing means (12) in said first opening state (A) being larger than a flow resistance of said closing means in said second opening state (B).

摘要： Hydraulic driving device with a hydraulic motor and a bearing arrangement in which the output shaft of the hydraulic motor is supported. Typically, the bearing arrangement is axially supported on the output shaft between a shoulder of the output shaft and a nut screwed onto the output shaft. To reduce overall length, the invention provides that the shoulder is located on the side of the bearing arrangement opposite from the end of the output side of the output shaft, and a friction-disc pack directly bears on the bearing arrangement. The motor has a braking device, including the friction-disc pack and at least one braking cylinder with a spring chamber and a release chamber. A braking valve in the braking position supplies the spring chamber with the load pressure and the release chamber with the tank pressure, and in the release position supplies the spring chamber with the tank pressure and the release chamber with the load pressure. The motor has a flushing line and a leakage line, which in one form of the invention are connected with the spring chamber and led to a tank via the braking valve. In another form of the invention, the leakage line is connected to the release chamber and the flushing line is connected to the spring chamber. In yet another form, the leakage line is connected to the spring chamber and the flushing line is connected to the release chamber. The combination of lines from the braking device and the flushing system results in simplifications.
