(54) Dual drive compressor


(57) Described is a compressor (10) for compressing gaseous fluids such as air which is adapted to be driven periodically via a rope pulley (16) through pulling on a rope (36) or alternatively is adapted to be driven continuously via a disc or wheel-shaped rotatable body (18). A drive shaft (14) is connected via two overrunning clutches (52, 56) to the rope pulley (16) or the rotating body (18) and the rope (36) can be rapidly rewound by means of a spring actuator. The drive through rotating body (18) enables the use of the compressor (10) with a bicycle, in which the rotating body (18) is frictionally coupled to a tire, in order to fill a compressed air storage container which can subsequently be used, e.g. for pumping up bicycle tires.
