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. Return-flow ducts between the pressure chambers assist for example the idling operation. For the torque amplification, one or more mechanical step-down stages can be used, more especially with the planetary gear sets, with phasewise superimposition of the step-down stages and automatic phase change.
