Abstract: A capacitive ignition system for an internal combustion engine includes a voltage converter which has two primary terminals and two secondary terminals a primary voltage source has two voltage source terminals (A+, A?) which are connected in each instance to one of the primary terminals so that a primary circuit is formed; a switch which is incorporated within the primary circuit and a controller so that the switch can be closed and opened; a first control device constructed to actuate the controller in accordance with an ignition pattern for closing and/or opening; an electrical capacitance (C1, C2) within the primary circuit; and a second control device (25) constructed to maintain constant a voltage rise at the secondary terminals, which occurs in order to reach the ignition voltage, as the ignition energy requirement of an ignition device connected to the secondary terminals changes.

Abstract: A turbine includes a stator (10) and a rotor (20); a plurality of turbine stages (30) through which a flow path of an operating fluid extends; an axial thrust balancing piston (40) arranged at the rotor and a first piston chamber (41) connected to one of the turbine stages (30.1) so that the operating fluid can be conveyed into the first piston chamber with a first fluid pressure, and a second piston chamber (42) has a counterpressure so that an axial thrust opposed to a flow direction of the operating fluid can be exerted on the rotor; and a pressure control device (60) connected to the second piston chamber. The pressure control device constructed to vary the counterpressure by controlled removal of fluid from the second piston chamber so that the axial thrust of the axial thrust balancing piston can be varied.

Abstract: The oil side-flow cleaning device includes a heating unit (11) installed between the oil tank and the filter unit (10) so that, when the oil temperature is below a defined limit value, oil flows through the filter unit (10) in such a way as to bypass the filtering function and is heated; and so that, when the oil temperature is above the defined limit, oil flows through the filter unit (10) so as to be subjected to the oil filtering function. In addition or as an alternative, the oil side-flow cleaning device comprises a backflush unit including a backflush collecting tank (17) and a backflush nozzle (18), wherein, when the device is in backflush mode, oil flows through the filter medium (16) in a second, opposite direction as a function of the position of the backflush nozzle (18) relative to the filter medium (16).
