Abstract

The multi level piston compressor has an intake valve chamber (13) whereby upstream compressor level (1) is arranged on the intake valve. An auxiliary valve (16) is connected with the cylinder space (11). The auxiliary valve is in stand still state in open position and moves in closed position. The differential pressure is examined in the down stream compressor level (2) of the exhaust valve chamber (25).
