Abstract

A control method for controlling the gas flow by a compressor in which a volume is expanded during an intake stroke and the intaken volume of gas is compressed and taken out through a non return valve ( 6 ) for outflow and/or an operable outlet valve ( 3 ) during an evacuation stroke, and in which the compressor has a controllable inlet valve ( 2 ) that is pneumatically, hydraulically or electromagnetically operable and that is opened and closed upon basis of a signal from a control system. The inlet valve ( 2 ) is kept closed during at least a part of an intake stroke.
