摘要： The present invention relates to an electrohydrostatic system having a hydraulic cylinder comprising a first cylinder chamber and a second cylinder chamber. Furthermore, the electrohydrostatic system has a fluid hydraulic supply device for providing a hydraulic fluid, a fluid hydraulic motor pump unit, designed to provide a fluid hydraulic volume flow in order to move the hydraulic cylinder. A motor control device is designed to provide a rated current for an electrical drive of the fluid hydraulic motor pump unit. Moreover, the electrohydrostatic system has at least one fluid hydraulic safety valve, which on a first valve side is connected to one of the cylinder chambers of the hydraulic cylinder and on a second valve side is connected to the fluid hydraulic motor pump unit. The fluid hydraulic safety valve can be bridged via a bypass connection with a fixed orifice plate, wherein the bypass connection is connected to the first valve side and to the second valve side of the at least one fluid hydraulic safety valve. Moreover, the electrohydrostatic system has a pressure sensor that is connected to one of the cylinder chambers of the hydraulic cylinder. The pressure sensor is designed to detect a fluid hydraulic pressure on one of the cylinder chambers and, according to the detected fluid hydraulic pressure, to provide an enabling signal for the motor control device to provide the rated current for the electrical drive of the fluid hydraulic motor pump unit.

摘要： The invention relates to a radial reciprocating engine (1) having cylinders (5) arranged in a cylinder carrier (16) and a piston element (21) arranged in each cylinder (5) that is connected to a guide element (22), wherein the guide element (22) runs on a slide surface (14), whereby a stroke movement is imposed on the piston element (21). Since the piston element (21) is spherical at least in the region of the piston element (21) which seals the inner walls (51) of the cylinder (5) during the stroke movements, a linear seal is created, which enables a more compact design in comparison to radial pumps with cylindrical piston elements.

摘要： A safe hydraulic drive system and process, comprising at least one first cylinder chamber and a second, separate cylinder chamber which are connected to one another via a connecting line to form a fluid-filled hydraulic circuit, and a hydraulic drive for conveying the fluid from one cylinder chamber, via the connecting line, into the other cylinder chamber in which the connecting line is arranged. The connecting line has at least one parallel system, between the hydraulic drive and one of the two cylinder chambers, including at least one first sub-connection with at least one first stop valve and a second sub-connection with a baffle arranged therein. The connecting line, excluding the second sub-connection, has a first flow resistance and the second sub-connection has a second flow resistance due to the baffle arranged therein, which is greater than the first flow resistance for the fluid, wherein the drive system is provided with at least one open first stop valve in normal mode and with a closed first stop valve in safe mode for conveying the fluid, and a suitably high second flow resistance has been selected so that a maximum permissible speed for a piston rod is not exceeded in safe mode, even when an external force acts on the drive system in the direction of movement of the piston rod.

摘要： The present invention relates generally to a weapon having an eccentrically-pivoted barrel (1) that is mounted on a movable base (2), and to a method of elevating and stabilizing such a barrel. A drive mechanism (3) acts between the barrel and the base to permit and enable the elevation of the barrel relative to the base to be selectively changed. A compensation device acts between the barrel and base to compensate for the unbalance of the barrel. The compensation device includes a gyroscope (13) mounted on the barrel and arranged to provide an output signal, a set point generator (12), a closed-loop control device (10) and an actuating element (16). The actual position of the barrel is sensed by the gyroscope, which supplies its output signal to the set point generator. The set point generator produces a set force value as a function of the gyroscope output signal. The set force value is supplied to the closed-loop control device, which produces a set point value that is, in turn, supplied to the actuator for controllably changing the elevation of the barrel.

The controller includes a memory (28) for receiving and storing a plurality of initial set points supplied from a keypad (29). A recalculation circuit (42) is operatively arranged to recalculate the magnitude of each set point according to the equation S.sub.n(r) =(S.sub.n(i) -G.sub.1)B+G.sub.2, where S.sub.n(r) is the recalculated value a particular set point, G.sub.1 is a first reference die gap, G.sub.2 is a second reference die gap, B is a scaling factor, and S.sub.n(i) is the corresponding initial set point stored in memory. The recalculation circuit is operatively arranged to supply each recalculated set point to the memory to replace the initial set point stored therein. The recalculated set points are supplied to the actuator, via an interpolator (30) for controlling movement of the mandrel during an extrusion cycle.

摘要： A control system for a hydraulic punch press is adapted to dissipate the energy stored in a hydraulic actuator so that the punch will exit the workpiece without substantial release impact. The control system includes a signal generator for producing a progressively increasing command signal while the punch penetrates the workpiece, a position transducer for producing a negative feedback signal indicating the actual punch position during such penetration, and a summing point for supplying the difference between the command and actual signals as an error signal to a servovalve used to control operation of the actuator.
