摘要： A control apparatus for an adjustable hydraulic machine includes a power amplifier for adjusting the hydraulic machine under the control of a control valve generally set by manual setting means. Limiting units are selectively and detachably attached to supporting means, and respond to excessive fluid pressure, flow, or torque, to influence a limiting valve which controls the flow to the control valve so that the power amplifier operates the adjusting means of the hydraulic machine to reduce the pumped amount of fluid so that normal operating conditions are automatically obtained. One or several limiting units can be attached and connected into the hydraulic circuit of the machine, and independently control the limiting valve.

摘要： The disclosure pertains to a crane drive system including a fluid crane motor for imparting horizontal motion and a fluid motor for actuating a hoist mechanism. A variable delivery pump drives the motors in a closed loop hydraulic circuit which includes control valves for starting and stopping the motors. Variable speed control of either or both motors is accomplished by varying the output of the pump.

摘要： A hydraulic transmission drive comprising a combustion engine, a main pump, and a hydraulic motor, is regulated by adjusting the output of the main pump by regulating means including a hydraulic motor and a regulating pump driven by the combustion engine and driving the regulating motor. An adjustable throttle means is connected with the outlet conduit of the regulating pump and influences the operation of the regulating motor so that when the main pump has an overload, its speed is reduced together with the speed of the combustion engine until the torque of the combustion engine is sufficient.

摘要： A hydraulic power transfer system, for use for example in the propulsion of a vehicle, comprising an engine, a fixed positive displacement pump driven by the engine, a fixed positive displacement pump driven by the engine, a variable positive displacement motor, a control valve controlling flow of liquid from the pump to the motor and a pressure responsive means responding to increase in hydraulic pressure at the motor to increase motor displacement and increase engine speed. The variable positive displacement motor may be the propulsion motor for the vehicle. The control valve may include a variable flowselecting device adapted to feed the motor some of the pressure liquid delivered by the pump and including a bypass to carry the remainder of the liquid carried by the pump back to reservoir. The pressure-responsive means may operate to limit hydraulic pressure to a value which having regard to the volumetric displacement of the pump will demand a driving torque from the engine less than the maximum torque of which the engine is capable.

摘要： D R A W I N G
A CONSTANT-SPEED ROTARY DRIVE OPERATING AT HIGH EFFICIENCY INCLUDES A HYDRAULIC MOTOR WITHIN A CLOSED FLUID CIRCUIT WHICH HAS A FLUID BYPASSING AND MULTIPLE-PUMPING ARRANGEMENT FOR MAINTAINING A CONSTANT RATE OF FLUID FLOW TO THE HYDRAULIC MOTOR. TWO OR MORE ROTARY PUMPS ARE DRIVEN AT THE SAME OR RELATED SPEEDS BY A VARIABLE-SPEED POWER INPUT DEVICE, AND AN AUTOMATIC VALVING ARRANGEMENT, RESPONSIVE TO CONDITIONS CHARACTERIZING THE FLOWS WHICH MUST BE BYPASSED TO OPERATE THE MOTOR AT CONSTANT SPEED, SELECTIVELY CHANNELS THE OUTPUT FLOWS FROM THE PUMPS IN SEQUENCES AND COMBINATIONS WHICH INSURE THAT THE POWER LOSSES ASSOCIATED WITH FLOW IN THE BYPASS FOR THE HYDRAULIC MOTOR ARE MINIMIZED FOR ALL RANGES OF INPUT-SPEED VARIATIONS.

摘要： A hydrostatic pump-and-motor transmission system, e.g. for a vehicle, in which the pump and the motor can have their displacement volumes varied in discrete steps to give a number of predetermined fixed ratios. The pump is either a swashplate or variable eccentric pump adjustable to and between predetermined settings, or, a plurality of fixed displacement pumps switchable on the hydraulic side between, e.g. small pump alone, large pump alone, both pumps together. The motor is either a multibank piston/cylinder motor with valving arrangements for cutting out one bank of cylinders from the fluid supply, or several separate motors - some disconnectable. A hand selector sets up the various conditions e.g. three alternative pump displacement values with the motor at maximum displacement and two conditions with the motor at minimum displacement and the pump at two of the three pump displacement values. Instead of using multibank motors and cutting out one bank, four motors on four wheels of a vehicle may give the maximum motor displacement condition, the motors of either the front or the rear wheels being cut off from the pump, for the minimum motor displacement condition.
