Abstract (en)
[origin: US5875807A] PCT No. PCT/EP95/02208 Sec. 371 Date Jan. 15, 1997 Sec. 102(e) Date Jan. 15, 1997 PCT Filed Jun. 8, 1995 PCT Pub. No. WO96/02795 PCT Pub. Date Feb. 1, 1996Fitting, especially for a continuous flow water heater. The submitted invention takes as its basis the problem of developing a fitting of the named type by which the formation of calcareous deposits on the rod protruding from the water control housing is lessened and the influence of such calcareous deposits on the controller action is completely eliminated. The problem is solved in that within water control housing (2), the control motion of membrane (24) is transmitted to a lever (3) whose center of rotation forms a shaft (4), rigidly connected to this lever (3) and whose pivot is sealed, leading to the exterior of water control housing (2). At the same time, shaft (4) is also the center of rotation for a second lever (5) which is likewise rigidly connected to it. Thus the stroke motion of the first lever (3) is transmitted to the exterior via shaft (4) as a rotary motion and subsequently the rotary motion of shaft (4) is re-converted, by means of second lever (5), into a stroke motion to control the gas outlet. The fitting serves to control gas flow depending on water flow especially for continuous flow water heaters.
