Abstract
A gas valve unit for adjusting a gas volume flow in a dual circuit gas burner of a gas appliance includes a valve body having a gas inlet and two gas outlets; and a control mechanism constructed to adjust the gas volumetric flow supplied to one of the gas outlets in a number of stages and to adjust the gas volumetric flow supplied to other one of the gas outlets in a number of stages.

A gas valve unit for adjusting a gas volume flow in a dual circuit gas burner of a gas appliance, comprising:
- a valve body having a gas inlet and two gas outlets;
- a control mechanism constructed to adjust the gas volumetric flow supplied to one of the gas outlets in a number of stages and to adjust the gas volumetric flow supplied to the other one of the gas outlets in a number of stages, the control mechanism including at least two first on-off valves and at least two first throttle points to adjust the gas volumetric flow supplied to the one of the gas outlets;
- and
- a first throttle path in which the first throttle points are disposed in series, and a connecting section arranged between each two adjacent first throttle points and linking one of the first on-off valves in an open state to the gas inlet,
- wherein the throttle points of the first throttle path—when viewed in a gas flow direction in the first throttle path—have an increasing flow cross-section.
A gas valve unit for adjusting a gas volume flow in a dual circuit gas burner of a gas appliance, comprising:
- a valve body having a gas inlet and two gas outlets;
- and
- a control mechanism constructed to adjust the gas volumetric flow supplied to one of the gas outlets in a number of stages and to adjust the gas volumetric flow supplied to the other one of the gas outlets in a number of stages,
- wherein the control mechanism includes first on-off valves to adjust the gas volumetric flow supplied to the one of the gas outlets and second on-off valves to adjust the gas volumetric flow supplied to the other one of the gas outlets,
- the control mechanism includes at least two magnetically acting bodies, with a first one of the magnetically acting bodies being provided for control of the first on-off valves and a second one of the magnetically acting bodies being provided for control of the second on-off valves, and
- each of the at least two magnetically acting bodies is a permanent magnet.
