Abstract
A gas valve unit for adjusting a volumetric gas flow which is fed to a gas burner of a gas device includes a valve chamber, an actuation shaft protruding out of the valve chamber, and at least two on/off valves arranged in the valve chamber. Further arranged in the valve chamber is at least one restrictor plate having at least two restrictor points, each of the restrictor points having at least one restrictor opening. The restrictor plate is accessible from a side of the valve chamber on which the actuation shaft is protruding from the valve chamber.
Claims21
A gas valve unit for adjusting a volumetric gas flow which is fed to a gas burner of a gas device, said gas valve unit comprising:
- a valve chamber;
- an actuation shaft protruding out of the valve chamber;
- at least two on/off valves arranged in the valve chamber;
- and
- at least one restrictor plate arranged in the valve chamber and having at least two restrictor points, each of the restrictor points having at least one restrictor opening, said restrictor plate being accessible from a side of the valve chamber on which the actuation shaft is protruding from the valve chamber,
- wherein the valve chamber has a plurality of plates arranged parallel to one another, one of the plates being formed by the restrictor plate, and
- one of the plates is formed by a valve sealing plate which forms valve seats of the on/off valves.
A gas valve unit for adjusting a volumetric gas flow which is fed to a gas burner of a gas device, said gas valve unit comprising:
- a valve chamber;
- an actuation shaft protruding out of the valve chamber;
- at least two on/off valves arranged in the valve chamber;
- at least one restrictor plate arranged in the valve chamber and having at least two restrictor points, each of the restrictor points having at least one restrictor opening, said restrictor plate being accessible from a side of the valve chamber on which the actuation shaft is protruding from the valve chamber;
- and
- a permanent magnet for actuation of the on/off valves,
- wherein the valve chamber has a plurality of plates arranged parallel to one another, said permanent magnet being arranged on a side of the on/off valves facing away from the plates.
A gas valve unit for adjusting a volumetric gas flow which is fed to a gas burner of a gas device, said gas valve unit comprising:
- a valve chamber;
- an actuation shaft protruding out of the valve chamber;
- at least two on/off valves arranged in the valve chamber;
- at least one restrictor plate arranged in the valve chamber and having at least two restrictor points, each of the restrictor points having at least one restrictor opening, said restrictor plate being accessible from a side of the valve chamber on which the actuation shaft is protruding from the valve chamber;
- and
- a permanent magnet for actuation of the on/off valves,
- wherein the permanent magnet is spaced away from the actuation shaft in a radial direction and is coupled to the actuation shaft in such a manner that a rotation of the actuation shaft causes a movement of the permanent magnet relative to the on/off valves.
