<p>A gas flow monitor is to be created in which a defined value range of the closing or nominal flow rate can be set by changing the bias of the spring without changing the lift of the closing/valve body with a consequential concomitant reduction or enlargement of the flow gap. For this purpose, the gas flow monitor comprises a gas-tight housing (1), which has a valve seat (5) in its interior for an axially movable closing body (12), and a pin (11) at whose inlet side the closing body (12) is fastened, which with a stop (17) located at its outlet-side end by the force of a closing spring (15) is supported on a guide (6) disposed in the housing (1) on an outlet side by way of a tubular spacer (16). The guide (6) has in its center a sleeve (10), adjustable in an axial direction in which the pin (11) is guided in a longitudinally movable manner. The spacer (16) and the sleeve (10) are firmly connected to each other.</p> |
