Abstract
A flow control for a continuous-flow water heater is used to control the flow of gas to a burner (24) of a heat exchanger (29) as a function of the passage of water, in which only one operating element has to be actuated. The reduction in apertures through the housing wall of the flow control, reduces the risk of leaks. Furthermore, manufacturing expenditure is minimized. To this end, in addition to the operating element (8), a switching element (9) is rotatably mounted on a spindle (7) projecting from the water-carrying housing (5), wherein a rotary movement of the operating element (8) can be transmitted via drivers (10; 11) to the switching element (9), which also has a switching contour (13) by means of which a fixedly arranged microswitch (14) can be actuated, by means of which an electronic ignition and monitoring device (3) can be electrically actuated, by means of which gas flow to the burner can be shut off.
