<p>A gas pressure flow regulator comprises a main valve part (10), a valve journal (20) and valve opening (13) and a drive mechanism(50). A receiving space (14) is arranged on the side facing the valve opening (13) out on the main valve part (10) and a switch magnet (30) for electrical on- and off-switching of the drive mechanism (50) of the valve journal (20) is arranged in the receiving space (14). Additionally, a magnet body (40) is provided at the end of the valve journal facing the switch magnet (30), and is free to move together with the valve journal (20) in the direction facing the switch magnet (30) and as long as the valve journal (20) reaches the selected opening point of the valve opening (13), the magnet body (40) provides magnetic induction at the switch magnet (30) in order to interrupt the electric switching of the drive mechanism (50) and to permanently hold the preselected opening point of the valve opening (13), so as to control the gas flow.</p> |
