Abstract (en)
[origin: WO2013170964A1] Device for supplying evaporated gas from a storage tank (1) for refrigerated liquefied gas with regulated pressure to a consumer (8), the requirements of which for pressure and mass flow of the gas vary widely, the device having: a motor operated high-pressure pump (3) for the liquefied gas, the driving rotational speed of which determines the mass flow of the pumped liquefied gas; downstream of the high-pressure pump (3) an evaporator (6) for the liquefied gas; downstream of the evaporator (6) a pressure-regulating valve (10) for the evaporated gas, the outlet of which is connected to the consumer (8); a first regulator (11), the measured variable of which is the pressure of the evaporated gas downstream of the pressure regulating valve (10) and the manipulated variable of which acts on the pressure-regulating valve (10); a second regulator (15), the measured variable of which is the pressure of the gas between the high-pressure pump (3) and the pressure-regulating valve (10) and the manipulated variable of which acts on a rotational speed controller (19) for the high-pressure pump (3); and means (17) for combining the manipulated variables of the two regulators (11, 15) in such a manner that the manipulated variable of the first regulator (11) additionally acts on the rotational speed controller (19).
