Regular polysemy and semi-productive sense extension

A device for mixing a gas current under pressure with an atomized mist of liquid, such as lubricating oil, having a casing partially filled with a supply of liquid, a through duct for the gas current, said duct extending through the casing and having a pressure reducing valve, a bypass for a partial gas current connecting the upstream side with the downstream side of the valve and including i.a. the unfilled portion of the casing, and a suction tube opening into a first atomization area in the bypass and adapted to discharge liquid drawn from the supply in the casing into the partial gas current flowing through the bypass, in which a second, controllable atomization area is provided connected in parallel with the valve in the through duct and in series with the first atomization area to introduce the partial gas current enriched by the liquid into the gas current flowing through the duct. The outlet opening of the bypass has a valve seat cooperating with a portion of the valve in a manner such as progressively to close the outlet of the bypass in response to opening movements of the valve.
