Abstract

A device for pressure reduction of a gaseous medium is proposed, having an inlet channel (2) in which the gas is supplied at high pressure, and having a restrictor device, which has a plurality of perforated discs (7) and reduces the pressure of the gas to a lower level. The restrictor device is constructed as a multi-stage control device and has a perforated cone (6) which is arranged such that it can be displaced in a perforated cage (4), the perforated cage (4) and perforated cone (6) being provided with perforations (13, 14). The movement of the perforated cone (6) is controlled as a function of the load range. <IMAGE>
