Patent number: 11738216Abstract: In a preferred embodiment, methods and systems for the control of the breathing gas supply from a pressure-leading supply conduit to one or more breathing masks of an oxygen emergency supply device in a passenger aircraft include an on/off valve arranged between the supply conduit and the one or more breathing masks. The valve can be blocked or released to control air supply based upon monitoring mass flow to the breathing masks. The valve, for example, is actuated to an open position until the error between the actual mass flow and a desired mass flow exceeds a maximal error value, whereupon the valve is actuated to a closed position until the error between the actual mass flow and the desired mass flow exceeds a minimal error value whereupon the valve is actuated to the open position and the mass flow monitoring cycle is repeated.Type: GrantFiled: July 9, 2020Date of Patent: August 29, 2023Assignee: B/E Aerospace, Inc.Inventors: Heiko Marz, Thomas Sauerbaum

Patent number: 10213630Abstract: The invention relates to a method for the control of the breathing gas supply, in particular of the oxygen supply, from a pressure-leading supply conduit (1) to one or more breathing masks (3) of an oxygen emergency supply device in an air vehicle, in particular in an aircraft, with which an on/off valve (2) is arranged between the supply conduit (1) and the one or the several breathing masks (3), with which valve the conduit connection can be blocked or released, with which a desired mass flow dependent on cabin pressure is set and the actual mass flow is detected, wherein in a first method step the valve (2) is activated in an opening manner until the error between the actual mass flow and the desired mass flow and which is summed over time exceeds a previously fixed maximal error value (4), whereupon the valve (2) in a second method step is activated in a closing manner until the error between the actual mass flow and the desired mass flow and which is summed over time exceeds of a previously fixed minimalType: GrantFiled: March 24, 2015Date of Patent: February 26, 2019Assignee: B/E Aerospace Systems GmbHInventors: Heiko Marz, Thomas Sauerbaum

Patent number: 8944096Abstract: A method for controlling the pressure and/or the flow rate of a fluid includes withdrawing flow energy from a fluid flowing through a pipeline (15). This energy is converted at least partially into electrical energy and used for the electrical control (65) of the flow rate and/or the pressure of a fluid. The device for controlling the flow rate and/or pressure of a fluid in a pipeline (20) has at least one electric generator (35), which is developed for the withdrawal of flow energy from a flowing fluid and for converting this energy at least partially into electrical energy. The device has a control mechanism (65) for controlling the flow rate and/or pressure of a fluid in a pipeline (20) with an electric driving mechanism supplied by the generator (35).Type: GrantFiled: July 30, 2009Date of Patent: February 3, 2015Assignee: B/E Aerospace Systems GmbHInventors: Ruediger Conrad, Heiko Marz
