EJECTOR DEVICE FOR CHARGING CONSUMED VESSEL OF GAS ODORISER Russian patent published in 2010 - IPC F04F5/54 F17D3/12 

FIELD: machine building.

SUBSTANCE: device consists of vessel with liquid odorant coupled with gas line via odorant metering device and main, and via second main connected with upper point of vessel. Further, the vessel consists of high pressure gas line and ejector, input of which is coupled with the gal line of high pressure via the third main with normally closed driven electric valve. Output of the ejector is communicated with the gas line through the fourth main. The vessel also consists of a vessel-storage filled with liquid odorant. The device is equipped with an auxiliary vessel, a lower point of which is connected with the lower point of the vessel via the fifth main and normally closed driven electric valve. An upper point of the auxiliary vessel is connected with a vacuum main of the ejector. Notably, the lower point of the vessel-storage is connected with the lower point of the auxiliary vessel through the sixth main and normally closed driven electric valve and is positioned above the upper point of the auxiliary vessel, while its lower point is located above the upper point of the vessel.

EFFECT: charging vessel with liquid without metering device shut-off and without break of continuous process of odorising.
