Abstract: A method of controlling a compressor in a transport temperature control unit having a prime mover providing power to the compressor. The compressor has a power requirement that varies depending on loading conditions. The method includes determining the maximum power available from the prime mover, determining the power requirement of the compressor, and adjusting the loading conditions of the compressor so that the power requirement of the compressor substantially equals the maximum power available from the prime mover. Preferably, the method includes starting the compressor at a low speed, varying the suction pressure as permitted by the maximum amount of power available until the suction pressure reaches a maximum suction pressure setting, and after the suction pressure reaches a maximum suction pressure setting, increasing the speed of the compressor as permitted by the maximum-amount of power available.

Abstract: A hybrid or battery type working machine including a hydraulic pump, an electric motor, an electric storage device, and a control device which controls a pump absorption horsepower maximum value in accordance with an amount of electricity stored in the electric storage device. The control device reduces the pump absorption horsepower maximum value by dividing the pump absorption horsepower maximum value into a plurality of regions having different target flow rates, and reduces the pump absorption horsepower maximum value from an old pump absorption horsepower maximum value corresponding to the pump absorption horsepower maximum value which has not yet been reduced to a new pump absorption horsepower maximum value corresponding to the pump absorption horsepower maximum value which has been reduced, so that temporal differences among the regions can increase in a descending order of a target flow rate.

Abstract: A fluid power pumping apparatus having a control system for limiting the power loading thereon to the power available from a motor (172) driving the apparatus, includes a variable displacement rotating piston pump (170). A compensating valve assembly (174) of a type known in the prior art is mounting on the pump. The compensating valve controls flow volume through the pump in response to pressure at an outlet (176) of the compensating valve. The outlet is connected to a variable load limiting control (180). The load limiting control includes a low flow adjustment which varies according to the position of a cam (186) which is connected to the swash plate of the pump, and a high-flow cut-off. The load limiting control reaches higher operating pressures while operating within the power delivery capabilities of the motor. Both the low flow adjustment and high-flow cut-off are manually adjustable to tailor the pump to the operating characteristics of the motor.

Abstract: The invention relates to a power control device for two variable displacement pumps, each with an adjusting device which can be acted upon by adjusting pressure, a power control valve associated therewith, which is acted upon by a first control pressure corresponding with the operating pressure of the variable displacement pump to be adjusted against a pressure difference in the direction of the control position, in which the adjusting pressure loading is controlled in the direction of reduced displacement of the variable displacement pumps along a hyperbolic control curve, whereby the pressure difference results from a spring-arrangement backpressure counteracting the first control pressure and a second control pressure corresponding with the operating pressure of the other variable displacement pump and with increase of the same drops from a maximum value to a minimum value. In order to set the latter value with the device, it is provided in accordance with the invention that the spring arrangement comprises a first and a second pressure spring, the first pressure spring is set to a force corresponding with the minimum value (.DELTA.p.sub.min) and the second pressure spring is set to a force corresponding with the difference (.DELTA.p.sub.max -.DELTA.p.sub.min) between maximum value (.DELTA.p.sub.max) and minimum value (.DELTA.p.sub.min) of the pressure difference, and the first pressure spring with its setting force and the second pressure spring with a force decreasing with increasing second control pressure act upon the power control valve.
