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.

摘要： A controlled proportional valve is provided, with a main slide valve section (4) containing a main slide valve, which section controls a flow of fluid between a pump connection (P) connected to a pump (2) and a tank connection (T) connected to a tank (6) and two work connections connected to a load (5) and which generates a load-sensing signal (LS.sub.INT) in dependence on the pressures at the work connections (A, B), and with a compensating slide valve section (3) which controls the pressure across the main slide valve section (4) in dependence on the load-sensing signal (LS.sub.INT). It is desirable to achieve a more rapid response time in a proportional valve of that kind, wherein the control means should be capable of being retrofitted to existing proportional valves. To that end, a control arrangement (10) which controls the pressure of the load-sensing signal (LS.sub.INT) to influence the actual volume flow and/or the actual pressure in the work connections (A, B) is provided.
