Abstract: A compressor for a tire-repairing kit contains a second toothed wheel provided with a journal. The journal is functionally connected to a piston in such a way that the piston moves up and down when the second toothed wheel rotates. The inertial forces of the piston carrying out the up and down movement are compensated by a counterweight which is embodied in an integral manner with the second toothed wheel and is fixedly connected thereof.
