摘要： The invention relates to a leakage oil return apparatus for a hydraulic motor. The apparatus is used for returning the oil leaked from the working pressure space of a motor (1) into a motor casing (12) from the casing (12) back to a return line (2) of the motor. Consequently, the return pump (5) driven by a shaft (3) of the hydraulic motor (1) has its suction side (7) connected with said casing (12) and its delivery side (6) conencted by way of non-return valves (4) with pressure and return lines (2) of the motor (1) in such a way that flow communication is established always with the line having a lower pressure. It is preferred that the return pump (5) have its delivery side (6) connected by way of a pressure proportional valve (8) with said casing (12). The pressure proportional valve (8) is adapted to receive its control from the pressure ratio between a casing pressure and a pressure in the delivery side (6) of the return pump (5) in such a way that, as the casing pressure goes down below a given pressure limit or approaches the pressure of 0 bar, the pressure proportional valve (8) switches the return pump's (5) volume flow to free circulation i.e. back to the casing (12).

摘要： The invention concerns a hydrostatic-mechanical gear for driving a mixed drum and, in particular, the drum of a concrete mixer vehicle. Cooling is provided for by the continuous removal of oil from a high pressure circuit, via a connecting pipe, and the constant feeding of the cooled oil, which has passed through an oil cooler, to the interior of a gear housing via a pipe. This pipe discharges into the interior of the gear housing immediately proximate a hydraulic motor. The oil then flows through the hydraulic motor, which is preferably a slow-speed radial piston motor, to reduce the noise generation of the hydraulic motor.

摘要： The tapping circuit forms part of a main fluid circuit which comprises a hydraulic motor having a preferred operating direction and at least two main pipes suitable for communicating with the cylinder block of the motor and constituting respectively, in said preferred operating direction, a feed main pipe and a discharge main pipe. The tapping circuit comprises a single tapping and removal valve connected continuously via a tapping pipe to that one of said main pipes which, in the preferred direction, serves for discharge purposes. This valve serves to replenish the fluid so as to cool it and/or to flush the internal space of the casing of the motor.

摘要： The invention relates to a method and apparatus for returning the oil drained from a working pressure space of a hydraulic motor into a motor casing to an oil line, which is connected to the motor and which is in communication via a divider with intra-motor flow channels which are in communication with the working pressure spaces. The oil seeping into the casing is conveyed by means of pressure variations internal of the hydraulic motor, pulsating consistently with rotating motion, into the oil line presently at a lower pressure and connected to the motor by way of said divider. Therefor, the casing space is connected by a return conduit through a one-way valve to at least one flow channel, which lies between the divider of the motor and the working pressure space of the motor.
