摘要： PURPOSE: To reduce an excess pressure in a drain oil chamber so as to avoid splashing loss by disposing a pump device between a drain oil port and a tank for sucking drain oil from the drain oil chamber of a motor. CONSTITUTION: A fluid flow from a hydraulic pump 1 is supplied to a nozzle 35 of a jet pump 34 through connection line 41 having a working pressure line 3 or 4 and a throttle element 42, a shuttle valve 40 and a working medium line 39. When the flow is discharged from the nozzle 35 at a high speed, a negative pressure is generated at an inlet portion of the jet pump. When this negative pressure reaches a value sufficiently overcoming a flow drag in a channel between a hydraulic motor 25 and a tank 9, drain oil is sucked from a drain oil chamber of the hydraulic motor 25 through a drain oil port 30. Kinetic energy of the sucked drain oil is converted into pressure energy for transferring the drain oil to the tank 9 through a drain oil line 38. Consequently, due to the suction of the jet pump 34, a liquid level in the drain oil chamber becomes lower than a level of a rotation driving mechanism, thus avoiding loss caused by splashing.

摘要： PURPOSE: To establish a stable running by performing a shift from a high gear ratio to a low one when the output speed of a converter is smaller than the specified value and the transmission ratio has been minimized before the shift operation. CONSTITUTION: A control device 4 actuates couplings K1 and K2 to make shifting from a high gear ratio to a low one if the output speed of a fluid motor 5 of a hydrostatic transmission 29, i.e., a signal from a sensor 14, is smaller than any set value and the transmission ratio is set to any value and has attained a minimum value generated by the running resistance before the shift operation of an under-the-load convertive transmission 7. Accordingly the stability in running of a vehicle operated by the fluid is enhanced, and hydrostatic converter 29 works following a mechanical under-the-load convertive transmission 7 so that stable running can be maintained without increasing the consumption of the fluid.

摘要： A control device for a hydrostatic drive for at least two actuators, having a variable displacement pump whose adjusting device is acted on in accordance with the displacement and/or the flow pressure, wherein each actuator has associated with it, in its hydraulic supply line, a control valve and a preceding displacement controller in the form of a pressure compensator, is simplified while ensuring accurate control. This is achieved by associating with the control device an electronic regulating device which, depending on a measuring element that detects the opening position of the pressure compensator, controls, by means of an adjusting member associated with the adjusting device, the displacement setting of the pump, increasing it as the opening of the pressure compensator(s) becomes larger and decreasing as the opening becomes smaller.
