In an arrangement for adjusting the clutch slip of a friction clutch arranged on the output side of an engine of a motor vehicle, a control variable, formed as a function of the operating point of the engine and of an associated set point value for the clutch slip read out of a characteristic diagram, is applied directly to a clutch control element which adjusts the clutch slip.

A device is provided for reducing the engine torque when shifting up a change-speed gear transmission connected downstream of an internal combustion engine. A final control element for influencing the engine torque is connected to a control circuit and causes a reduction in the engine torque only in the full load range of the internal combustion engine and only above a limit value of the negative changes in engine speed over time. Comparator circuits for positive changes in speed over time are connected to the final control element such that the reduction in engine torque is blocked above a limit value of the positive changes in speed over time. In this way, overshoots triggered by positive changes in speed over time cannot result in a reduction in the engine torque.

This invention relates to a suction housing of a lubricating-oil pump inserted in a lubricating-oil storage tank of an aggregate of vehicles having a distributing regulator with a mass that is guided in the direction of the accelerating forces affecting the vehicle for the regulating of valve openings. In order to obtain a suction housing with a low overall height and a simple arrangement of valves, the distributing regulator is developed to be plate-shaped in which case the valves are movably suspended at the sides of the distributing regulator.
