Abstract: Device for supplying evaporated gas from a storage tank to a consumer at varying pressure and mass flow requirements, having: a high-pressure pump for the liquefied gas, the speed of which determines the mass flow of the pumped liquefied gas; an evaporator for the liquefied gas; a pressure-regulating valve for the evaporated gas, the outlet of which is connected to the consumer; a first regulator, the measured variable of which is the pressure of the evaporated gas and the manipulated variable of which acts on the pressure-regulating valve; a second regulator, the measured variable of which is the pressure of the gas and the manipulated variable of which acts on a rotational speed controller for the high-pressure pump; and means for combining the manipulated variable of the two regulators in such a manner that the manipulated variable of the first regulator additionally acts on the rotational speed controller.

Abstract: Device for supplying evaporated gas from a storage tank for refrigerated liquefied gas with regulated pressure to a consumer, the requirements of which for pressure and mass flow of the gas vary widely, the device having: a motor operated high-pressure pump 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 an evaporator for the liquefied gas; downstream of the evaporator a pressure-regulating valve for the evaporated gas, the outlet of which is connected to the consumer; a first regulator, the measured variable of which is the pressure of the evaporated gas downstream of the pressure regulating valve and the manipulated variable of which acts on the pressure-regulating valve; a second regulator, the measured variable of which is the pressure of the gas between the high-pressure pump and the pressure-regulating valve and the manipulated variable of which acts on a rotational speed controller for the high-press
