DEVICE FOR STABILISING PRESSURE IN RESERVOIR OF CRYOGENIC GAS FUEL (VERSIONS)

摘要

FIELD: engines and pumps.SUBSTANCE: invention relates to devices for controlling and stabilising pressure of liquids and gases in containers, particularly in cryogenic fuel tanks of locomotives and stability of fuel supply to the engine by stabilisation of pressure in the reservoir in a given range. Cryogenic tank pressure stabilisation device comprises reducing release valve, pressure sensor, electric heater, which is fixed on outer side of inner vessel in vacuum insulation cavity. Also pressure stabilisation device can contain pipeline fitted in cavity of inner vessel connected to a compressed fuel gas tank through gas reducers unit and normally closed valve controlled by pressure in the internal vessel.EFFECT: technical result is improvement of pressure stabilization in internal vessel of cryogenic gas fuel tank in the range that ensures stable supply of fuel to engine without using cryopumps in conditions of weight and dimensional restrictions.2 cl, 2 dwg
