| An operational control device is disclosed for a positive-displacement pump having a motor, means for actuating the motor, state sensor means for detecting an actual operating parameter (e.g., pressure) of the pump, and operating mode means for controlling an operating mode of the pump. A first actuating mode of the operating mode means is set by the actuating means below a first operating-parameter threshold value (P1). This mode brings about a constantly rising pump pressure in the direction of an operating-parameter setpoint value (Pset) in a variable manner, which is dependent on a detected change in the operating parameter over a predefined time interval. A second actuating mode is set as normal operation to the operating-parameter setpoint value by the actuating means above the first operating-parameter threshold value. P1 is fixed or is calculated as a fraction of the operating-parameter setpoint value and/or a pump parameter correlated therewith. | ||||||

| A hydraulic pump or motor includes a body having a chamber and a rotor rotatably mounted within the chamber. The chamber and rotor are shaped to define one or more rise regions, fall regions, major dwell regions and minor dwell regions between walls of the chamber and the rotor. The rotor has a plurality of slots and vanes located in each slot. Each vane is movable between a retracted position and an extended position. In the retracted position, the vanes are unable to work the hydraulic fluid introduced into the chamber whereas they are able to work the hydraulic fluid introduced into the chamber in the extended position. A vane retaining member that is selectively actuable enables the vanes to be retained in the retracted position. | ||||||

| The present disclosure relates to a hydraulic drive having a stationary housing. The hydraulic drive also has a drive shaft that extends through the stationary housing. Furthermore, the hydraulic drive has a hydraulic motor for rotating the drive shaft relative to the stationary housing. Additionally, the hydraulic drive includes a driven hub adapted to be connected to a rotatable driven element. The hydraulic drive also has a coupling/decoupling arrangement that allows the hydraulic drive to be operated in an engaged mode where the drive shaft is coupled to the driven hub in a direct drive arrangement and a disengaged mode where the drive shaft is decoupled from the driven hub. When the hydraulic drive is operated in the engaged mode torque from the drive shaft is transferred to the driven hub causing the driven hub to rotate relative to the stationary housing. When the hydraulic drive is operated in the disengaged mode the driven hub can free wheel relative to the drive shaft. | ||||||

| A control system for a variable displacement pump driven by a drive source for driving a vehicle is provided. The variable displacement pump pressurizes hydraulic oil, and is switchable between a full capacity operation in which a discharge flow rate is maximized and a partial capacity operation in which the discharge flow rate is lower than that in the full capacity operation. It is determined whether an operation for starting the drive source has been performed. A rotational speed of the drive source and a temperature of the hydraulic oil are detected. When the rotational speed of the drive source is equal to or higher than a predetermined rotational speed and the hydraulic oil temperature is equal to or lower than a predetermined temperature, immediately after the operation for starting the drive source is performed, the partial capacity operation of the variable displacement pump is performed. This control suppresses generation of untoward noises caused by the operation of the variable displacement pump when starting to drive the vehicle. | ||||||

| A turbomachine that can be operated as a motor and as a pump, having an axially fixedly mounted shaft, including a power section with rotating inlet and outlet and an associated controller. Because the axial forces (Fgx) have been made independent of the sense of rotation the turbomachine is significantly more reliable, and because the sealing forces have been adjusted it has significantly greater reliability (η) in both running directions. It can be operated with fluids and gases. The turbomachine can be extended by adding a control device and a drive for the control device so as to provide a freewheel function, a braking function and/or blocking function, and so as to shift, modify and optimize the characteristic curves across the entire control range. In both the clockwise and anticlockwise directions the turbomachine has in principle the same properties, although these can be modified and optimized by the control device. | ||||||
