foerfarande and foer oil injection device to a rotationskompressor of deplacementstyp

摘要

A conduit system for oil injection has gas fed to the injection oil to alter the compressibility of the gas-oil dispersion and thereby alter the inherent frequency for the hydraulic vibrations in the channels and conduits. A regulatable connection (12,13) for gas to an oil injection (6) is arranged so that gas is adjustably fed to the oil to alter the compressibility.
