Abstract

Gasbeheizter Durchlaufwasserheizer (1) mit einem von einem atmosphärischen Gasbrenner (14) beheizten Wärmetauscher (3), dem ein an einem Wasserschalter (3) angeordnetes Wasserventil vorgeschaltet ist und dem gasseitig zwei Gasventile (36, 44) vorgeschaltet sind, von denen eines vom Wasserschalter (5) und das zweite von einem gasdruckgesteuerten Servoventil (29) gesteuert ist, die beide in Serie liegen. Unter Verzicht auf einen Zündbrenner mit seinem Zündgasventil ist das Servoventil (29) mit seinem Gehäuse (51) so aufgebaut, daß sein Innenraum (58) zwei von einer Membran (57) separierte Kammern (59, 60) aufweist, von denen eine (59) mit dem Gasweg (83) stromauf der beiden Gasventile (36, 44) verbunden ist, während die zweite Kammer (60) über ein von einem Elektromagneten (71) betätigbares Ventil (63/65) mit dem Gasweg (83) stromab des ersten Gasventils (36) verbunden ist. Die Membran (57) weist einen den Ventilkörper (37) des Gasventils (36) tragenden Mitnehmer (76) auf, dessen dem Ventilkörper (37) zugewandtes Ende (85) diesen erst nach Durchlaufen eines Spiels (79) gegen die Rückstellkraft einer Feder (80/81) mitnimmt.
