An actuating device ( ) for carrying out mechanical work by means of a slave piston rod ( ) in a hydraulically-operated slave cylinder ( ), where the actuating device ( ) is made up of a hydraulic pump ( ) integrated with a slave cylinder ( ) and where the hydraulic pump ( ) is driven by a linear electric motor, which consists of a pump piston ( ) which is used as rotor in the linear motor at the same time as the pump piston ( ) functions as a pumping piston in the hydraulic pump ( ) to build up a hydraulic pressure in the slave cylinder ( ).

Electrohydraulic setting device

A device that includes a combustion engine with a piston that is mechanically freely movable in a housing. The device permits combustion of a fuel mixture to produce a pushing force to the piston. The device includes an electromagnetic energy transducer and an external current circuit, which is connected to the energy transducer for exchange of effect in a direction to or from the energy transducer. A control unit controls the direction of the effect, which is exchanged between the energy transducer and the external current circuit, during operation of the device. Such a device can be used to generate electrical energy, and can be employed in a vehicle.

Device including a combustion engine, a use of the device, and a vehicle

A device for control of power (P) generated by a gas turbine (1) which drives an electric generator (2) with a rectifier (3) connected thereto, comprises a control member (6) adapted to control the fuel supply of the gas turbine (1) in such a way that the inlet temperature (T) of the gas turbine is caused to correspond, at least substantially, to a predetermined value (TR). A direct-voltage network (4) with controllable voltage (U) is connected to the rectifier (3) and the control member (6) generates a voltage control signal (URs) which is supplied to the direct-voltage network (4) .
