Abstract (en)

[origin: DE4425200A1] The present invention is to develop a flow control of the stated kind in which the furring of the rod projecting from the water containing housing (2) is reduced and the effect of such fur on the control behaviour is completely eliminated. This problem is solved in that the control movement of the diaphragm (24) in the water containing housing (2) is transmitted to a lever (3), the pivot of which is formed by a sealed shaft (4) firmly secured to said lever (3) and leading to the outside of the water containing housing (2). At the same time, the shaft (4) is also the pivot of a second lever (5) also firmly secured to it. The lifting movement of the first lever (3) is thus converted via the shaft (4) to the exterior as a rotary movement and then the rotary movement of the shaft (4) is reconverted by the second lever (5) into a lifting movement to control the gas flow. The flow control is used to control the gas flow depending on the water flow, especially for instantaneous water heaters.
