Abstract:
A regulator for regulating a liquid medium flow to a device comprising:a first pressure chamber, charged with a first pressure level, said first pressure chamber being connected to a gas volume at a first pressure level;a second pressure chamber, charged with a second, lower pressure level, connected to a liquid medium supply via a first flow resistance;a third pressure chamber having a third pressure level that corresponds to the pressure of the device connected to said regulator;a control element disposed between said first and second pressure chambers and a spring element for biasing said control element, said spring element adapted to be compressed as a function of the pressure in the first pressure chamber relative to the pressure in the second pressure chamber; anda variable flow resistance disposed between said second and third pressure chambers which influences the medium flow supplied to the device, wherein the flow rate through the variable flow resistance is a function of the force exerted by the first pressure chamber as well as the forces exerted by the second and third pressure chambers, and the flow rate through the variable flow resistance, being increased due to the spring force.
