Abstract: Self-pumping hydropneumatic shock absorbing strut with internal level control, in particular for motor vehicles, in which, to regulate the level, a pump which is driven by the movements of the spring transports damping medium from a low pressure chamber which is under a lower pressure into a high pressure chamber which is constantly pressurized by the respective spring force of the shock absorbing strut. During this process, when a specified level is exceeded, the damping medium can flow back into the reservoir via a regulating device, whereby the regulating device is a recess between the work chamber and the low pressure chamber, which regulating device can be controlled by a magnetically actuated closing element.

Abstract: A hydrokinetic torque converter which includes pump wheels and/or turbine wheels in particular of a Fottinger coupling, wherein all the required blades are stamped in the form of blade blanks, out of a round stamping blank in a single operating process, in such a manner that each blade blank remains connected, by means of a connecting web, to a ring-shaped area of the stamping blank which remains intact during the stamping. The blade blanks are then subjected to a shaping process, in which they are reshaped into the final three-dimensional shape of the blade, whereby the connection with the ring-shaped area remains intact, and, in a shaping process, the ring-shaped area is adapted to the contour of the housing that delimits the pump wheel or turbine wheel. A blade carrier is thereby produced which makes it possible to install all the blades, in their three-dimensional position with respect to the pump or turbine wheel, in a single process.

Abstract: A hydrokinetic torque converter has a main impeller driven by an internal combustion engine, an auxiliary impeller that can be engaged into drive connection with the main impeller by an impeller clutch, a turbine coupled to an output shaft, and a stator which together form a converter circuit filled with hydraulic fluid. The impeller clutch has a clutch member that engages with the auxiliary impeller in a rigid, non-rotatable fashion. The clutch member forms the separating wall between two chambers, each of which is connected by at least one fluid flow passage to an associated hydraulic line, which leads to a supply system and acts depending on its operating state, as an inflow or outflow line creating a pressure gradient between the chambers. Based on the pressure gradient the clutch member can be set in either a first position, in which it is connected in rotary fashion to the converter housing, or in a second position, in which this rotary connection is released.

The emergency starting attempt can be initiated by the driver by means of a control mechanism, e.g. a manually actuated control switch or the accelerator pedal. If necessary, the speed threshold can be measured by means of a speed sensor.
