    Abstract: A displacement pump arrangement, method for operating the displacement pump arrangement and a control device for controlling the displacement pump arrangement provide rotational-speed-variable control of an expeller pump unit for feeding a fluid. The arrangement includes an expeller pump and a drive, the drive being composed of an electric drive motor and a frequency converter, and a control device. The control device controls a state value such as a final pressure of the expeller pump a setpoint value. The control device detects state values of a control variable are supplied by the drive, in particular relating to the position, rotational speed and torque of the drive motor, and adjusts the displacement pump output to reach the setpoint value without using sensors.

    Abstract: A method and a system for determining a setting parameter of a hydrostatic displacement unit is provided. In the method, a pressure value, a rotational speed value, and a torque value are determined. The setting parameter can be determined with use of the pressure value, rotational speed value, torque value of the setting parameter characteristic diagram, and a setting parameter characteristic diagram, which is an inverted efficiency characteristic diagram, which has at least pressure, rotational speed, and torque as input parameters. The system can include a system unit for determining a pressure value, a system unit for determining a rotational speed value, a system unit for determining a torque value, and a system unit for determining the setting parameter with use of the pressure value, rotational speed value, torque value, and a characteristic diagram, whereby the system for determining a setting parameter is formed so that during the determination of the setting parameter it can use as a characteristic diagram a setting parameter characteristic diagram, which is an inverted efficiency characteristic diagram or torque characteristic diagram, which has at least pressure, rotational speed, and torque as input parameters.

    Abstract: A power pump performance analysis system and methods includes a signal processor connected to certain sensors for sensing pressures and stresses in the cylinder chambers and the inlet and discharge piping of a single or multicylinder pump. Pump speed and pump piston position may be determined by a crankshaft position sensor. Performance analyses for pump work performed, pump cylinder chamber stress, pump fluid end useful cycles to failure, and crosshead loading and shock analysis are provided for estimating pump component life and determining times for component replacement before failure.

    Abstract: A high pressure pump for a common rail fuel system avoids torque reversals in its cam shaft by applying a cyclic parasitic load. As the high pressure pump pistons transition from a pumping stroke to a retraction stroke, the cyclic parasitic loading device is loaded to avoid torque reversals in the cam shaft. The cyclic parasitic load device may include a medium pressure pump, such as for supplying medium pressure fuel to a particle trap regeneration device associated with the exhaust after treatment system.

    Abstract: A torque control for a hydrostatic piston pump that provides for a servo piston rod that is connected to the swashplate of the pump and connected to a servo piston within a first cavity that receives compensation pressure that urges the servo piston toward the swashplate. The servo piston has a stem that extends into a bore and is in contact with the stem of a maximum displacement piston that extends into a second cavity that is acted upon by system pressure to urge the maximum displacement piston toward the swashplate. Additionally, within the second cavity is a set of Bellville washers that surround the stem of the maximum displacement piston to limit the movement of the maximum displacement piston toward the swashplate.

    Abstract: In order to provide a construction machine by which energy regeneration can be performed reliably and battery and electrical power generator can be miniaturized, a construction machine has an engine, a hydraulic pump driven by the engine, and an actuator driven by discharge oil from the hydraulic pump, and a regenerative motor which rotates by return oil from the actuator is connected to the rotation shaft of the hydraulic pump. The hydraulic pump is driven by the engine and the regenerative motor when drive torque necessary in the hydraulic pump is larger than output torque generated by operation of the regenerative motor. Meanwhile, the hydraulic pump is driven by the regenerative motor when the drive torque of the hydraulic pump is smaller than output torque of the regenerative motor, and an electrical power generator connected to the rotation shaft of the hydraulic pump is operated to generate electricity by excess torque which has not been energy-regenerated in the hydraulic pump so that this generated electrical power is charged in a battery.
