Abstract (en)

[origin: EP0035147A1] 1. A gas pressure regulator for a circulating water heater provided with a heater for water for consumption, including a valve seat (33), which is disposed in a housing (30) and controlled by a springresettable valve member (35), which is connected to a positioning diaphragm (38), which is subjected to the gas pressure behind the valve (33/35) in the outlet chamber (32), also comprising a first control diaphragm (54), which is subjected on one side to the gas pressure behind the valve (33/35), and a fluid pump (83), wherein that side of the first control diaphragm (54) which is remote from the gas is subjected only to the pressure of the fluid pump (83) and that pressure is limited by a valve (75/76), which is coupled to a second control diaphragm (60), which is biased by a spring (62), characterized in that a backing member (63) for the spring (62) of the second control diaphragm (60) is connected to a positioning rod (15) of a flow switch (16), which is associated with a tap water path (20, 21, 22) of the heater (7) for water for consumption.
