A gas valve unit for adjusting a gas volume flow fed to a gas burner of a gas-operated device, particularly a gas cooking appliance, includes a valve body, in which at least two valve seats of open-close valves of the gas valve unit are formed. At least two throttle points each having at least one throttle opening are formed in the valve body. The valve body includes a plurality of mutually parallel plates, with one of the parallel plates forming a valve sealing plate with the at least two valve seats of the open/close valves and another of the parallel plates forming a throttle plate with the throttle openings of the at least two throttle points. The valve sealing plate is made of a flexible material, such as plastic.

1. A gas valve unit for adjusting a volumetric gas flow supplied to a gas burner of a gas appliance, said gas valve unit comprising: a plurality of open/close valves,a valve body comprising a plurality of mutually parallel plates and at least two valve seats of the open/close valves, andat least two throttle points, with each of the at least two throttle points having at least one throttle opening,wherein one of the parallel plates forms a valve sealing plate with the at least two valve seats of the open/close valves and another of the parallel plates forms a throttle plate with the throttle openings of the at least two throttle points, andthe throttle openings are fixed open. 2. The gas valve unit of claim 1, wherein the gas appliance is a gas cooking appliance. 3. The gas valve unit of claim 1, wherein the valve sealing plate is made from a flexible material. 4. The gas valve unit of claim 3, wherein the valve sealing plate is made from plastic. 5. The gas valve unit of claim 1, wherein each open/close valve has a shut-off body seated on the valve sealing plate when the open/close valve is closed. 6. The gas valve unit of claim 5, wherein the valve sealing plate comprises an orifice arranged in a region of each valve seat, and wherein the shut-off body seated on the valve sealing plate seals the orifice when the open/close valve is closed. 7. The gas valve unit of claim 5, further comprising at least one permanent magnet producing a force for moving the shut-off body. 8. The gas valve unit of claim 5, wherein each open/close valve comprises a spring constructed to pretension the shut-off body toward the valve sealing plate. 9. The gas valve unit of claim 5, further comprising a pressure plate made from substantially rigid material arranged on a side of the valve sealing plate facing away from the shut-off body. 10. The gas valve unit of claim 9, wherein the substantially rigid material is a metal. 11. The gas valve unit of claim 9, wherein the pressure plate has apertures corresponding to orifices arranged in the valve sealing plate. 12. The gas valve unit of claim 11, further comprising a first gas distribution plate arranged between the pressure plate and the throttle plate, said first gas distribution plate having apertures corresponding to the apertures in the pressure plate and to the throttle openings in the throttle plate. 13. The gas valve unit of claim 12, wherein a open/close valve assigned to an aperture of the first gas distribution plate connects the aperture substantially unthrottled to a gas inlet of the gas valve unit when the open/close valve is open. 14. The gas valve unit of claim 12, further comprising a second gas distribution plate arranged on a side of the throttle plate facing away from the first gas distribution plate, wherein the second gas distribution plate comprises apertures corresponding to the throttle openings in the throttle plate. 15. The gas valve unit of claim 14, wherein precisely one aperture of the second gas distribution plate is connected to a gas outlet of the gas valve unit. 16. A gas valve unit for adjusting a volumetric gas flow supplied to a gas burner of a gas appliance, said gas valve unit comprising: a plurality of open/close valves;a valve body comprising a plurality of mutually parallel plates and at least two valve seats of the open/close valves;at least two throttle points, with each of the at least two throttle points having at least one throttle opening, one of the parallel plates forming a valve sealing plate with the at least two valve seats of the open/close valves and another of the parallel plates forming a throttle plate with the throttle openings of the at least two throttle points;a pressure plate made from substantially rigid material, the pressure plate having apertures corresponding to orifices arranged in the valve sealing plate; anda first gas distribution plate arranged between the pressure plate and the throttle plate, the first gas distribution plate having apertures corresponding to the apertures in the pressure plate and to the throttle openings in the throttle plate,wherein each open/close valve has a shut-off body seated on the valve sealing plate when the open/close valve is closed,the pressure plate is arranged on a side of the valve sealing plate facing away from the shut-off body, andat least some of the apertures in the first gas distribution plate connect two adjacent throttle openings of the throttle plate with one another. 17. The gas valve unit of claim 16, wherein the throttle openings are fixed open. 18. A gas valve unit for adjusting a volumetric gas flow supplied to a gas burner of a gas appliance, said gas valve unit comprising: a plurality of open/close valves;a valve body comprising a plurality of mutually parallel plates and at least two valve seats of the open/close valves;at least two throttle points, with each of the at least two throttle points having at least one throttle opening, one of the parallel plates forming a valve sealing plate with the at least two valve seats of the open/close valves and another of the parallel plates forming a throttle plate with the throttle openings of the at least two throttle points;a pressure plate made from substantially rigid material, the pressure plate having apertures corresponding to orifices arranged in the valve sealing plate;a first gas distribution plate arranged between the pressure plate and the throttle plate, the first gas distribution plate having apertures corresponding to the apertures in the pressure plate and to the throttle openings in the throttle plate; anda second gas distribution plate arranged on a side of the throttle plate facing away from the first gas distribution plate, wherein the second gas distribution plate comprises apertures corresponding to the throttle openings in the throttle plate,wherein each open/close valve has a shut-off body seated on the valve sealing plate when the open/close valve is closed,the pressure plate is arranged on a side of the valve sealing plate facing away from the shut-off body, andat least some of the apertures in the second gas distribution plate connect two adjacent throttle openings of the throttle plate with one another. 19. The gas valve unit of claim 18, wherein adjacent throttle openings of the throttle plate that are connected by the apertures in the second gas distribution plate are throttle openings that are not connected by the first gas distribution plate. 20. The gas valve unit of claim 18, wherein the throttle openings are fixed open.
