Abstract: A drive mechanism, in particular for motor vehicles having a combustion engine including at least one compressor of the displacement type integrated by way of members of a planetary gear drive into the transmission train, and which by means of valves can be regulated infinitely variably and which on the suction side serves for cooling the installation and on the motor side for supplying charging air and on the power take-off side serves to increase the rate of rotation. The reaction force of the compressor is transmitted to the planetary wheels of a gear assembly driven with down gearing and there counteracts the deviation movement, i.e. the pivoting of the planetary gears when under load. A differential gear mechanism between the gear assembly on the one hand and the compressor respectively gear casing on the other hand including two planetary gear members connected to permit a gear ratio range from idling up to 1:1.

Abstract: A drive system especially for motor vehicles and the like, with a conventional internal combustion engine, having at least planetary gearing and a mechanism for the mechanical boosting of the engine, comprising a compressor with displacement effect, a forwardly disposed low pressure chamber and rearwardly disposed high pressure chamber, which are connected together by return-flow ducts and throttle valves. Power transmission, speed change and engine boosting are controlled in running operation by throttling the air flow, in which respect the compressor, driving by way of a system-specific distributor gear, transmits power back to the distributor gear as a reaction element and thus forcibly influences the drive torque or speed of rotation of the power take-off shaft, while on the other hand as a compressor it provides charging air, stationary low pressure in the intake-side of the low pressure chamber makes possible an autonomous cooling of the system.
