  • the invention relates to a gas control device with attached Venturi nozzle according to the preamble of claim 1.
  • a gas control device with attached Venturi nozzle has a housing and a gas valve positioned in the housing for influencing a gas flow provided by the gas control device.
  • the housing of such a gas control device has a housing wall with a gas outlet opening, via which the gas flow of the mounted Venturi nozzle can be fed. In such a venturi, the gas flow provided by the gas regulator is miscible with an air flow so as to provide a gas-combustion air mixture.
  • EP 1 953 453 A1 discloses a gas control device according to the preamble of claim 1.
  • the invention is based on the object to provide a novel gas control device with attached Venturi nozzle.
  • the Venturi nozzle component forming the inlet funnel of the Venturi nozzle and the Venturi nozzle component forming the outlet nozzle of the Venturi nozzle are each manufactured as separate assemblies by injection molding from plastic.
  • the receptacle has a directly on the housing of the gas control device, namely at the gas outlet opening having the housing wall of the housing, engaging first portion, in which the gas outlet opening of the housing of the gas control device opens.
  • the receptacle has a second section engaging indirectly via the first section on the housing of the gas control device, which has a receiving opening for the Venturi nozzle components forming the inlet funnel and the outlet funnel, wherein the receiving opening is positioned laterally next to the housing wall of the housing of the gas control device having the gas outlet opening is.
  • the present invention relates to a gas control device with attached Venturi nozzle.
  • Fig. 1 shows a preferred embodiment of the invention in a partial exploded view of the gas control device and the Venturi nozzle.
  • a gas control device 10 which comprises a housing 11, wherein in the housing 11 at least one gas nozzle, not shown, is positioned, by means of which a gas flow provided by the gas regulator 10 can be influenced.
  • a gas outlet opening 13 is formed on a housing wall 12 of the housing 11 of the gas control device 10, through which the gas flow provided by the gas control device 10 leaves the gas control device 10 and can be supplied to a Venturi nozzle 14 attached to the gas control device 10.
  • a gas inlet opening 15 of the gas control device 10 is formed in the embodiment shown on a housing wall 12 opposite housing wall 16.
  • the gas flow provided by the gas control device which leaves the gas control device 10 via the gas outlet opening 13 can be supplied to the venturi nozzle 14 attached to the gas control device, wherein in the venturi nozzle 14 the gas flow provided by the gas control device 10 is miscible with an air flow, so as to provide a gas-combustion air mixture for a gas burner.
  • the Venturi nozzle 14 is formed by two Venturi nozzle components, namely a Venturi nozzle component 17 forming an inlet funnel of the Venturi nozzle and a Venturi nozzle component 18 forming an outlet funnel of the Venturi nozzle 14.
  • the receptacle 19, which is embodied as an integral part of the housing 11, is manufactured together with the housing 11 as an integral, monolithic assembly by casting a metallic material, in particular by casting aluminum.
  • Housing 11 and receptacle 19 thus form an integral, monolithic, metallic assembly.
  • the Venturi nozzle component 17 forming the inlet funnel of the Venturi nozzle 14 and the Venturi nozzle component 18 forming the outlet nozzle of the Venturi nozzle are each manufactured as separate assemblies by injection molding from a plastic, in particular a thermoplastic.
  • the receptacle 19, which is an integral, monolithic component of the housing 11 of the gas control device 10, is in particular trough-shaped, wherein the trough-like receptacle 19 has two sections 20 and 21, which together form the preferably trough-like receptacle 19.
  • a first portion 20 of the receptacle 19 acts directly on the housing 11 of the gas control device 10, namely at the gas outlet opening 13 having housing wall 12 of the housing 11. In this first portion 20 of the receptacle 19 opens the gas outlet 13th
  • a second portion 21 of the receptacle 19 engages via the first portion 20 of the receptacle 19 indirectly to the housing wall 12 of the housing 11 of the gas control device 10, said second portion 21 a receiving opening 22 for the inlet funnel forming Venturi nozzle member 17 and the outlet funnel forming Venturi nozzle member 18 has.
  • This receiving opening 22 is positioned laterally next to the gas outlet opening 13 having housing wall 12 of the housing 11 of the gas control device 10.
  • the gas outlet opening 13 of the gas control device 10 and the receiving opening 22 of the receptacle 19 are therefore formed on a first side of the receptacle 19.
  • the first portion 20 of the receptacle 19 is closed in the region of this first side of the receptacle 19 by the housing wall 12 of the housing 11 of the gas control device 10 and interrupted only by the gas outlet 13.
  • the receiving opening 22 for the venturi nozzle components 17 and 18 of the venturi nozzle 14 is formed on this first side of the receptacle 19.
  • the same is preferably opened continuously, this opening being partially closed in the assembled state.
  • Both the inlet funnel of the venturi 14 forming Venturi nozzle member 17 and the venturi of the Venturi nozzle 14 forming venturi nozzle member 18 are inserted or inserted into the receiving opening 22 of the receptacle 19, namely such that the the inlet funnel of Venturi nozzle 14 forming Venturi nozzle member 17 is inserted with the interposition of a seal 23 in the second portion 21 of the receptacle 19 and the receiving opening 22 of the second portion 21 of the receptacle 19 penetrates.
  • This seal 23 seals the Venturi nozzle component 17 forming the inlet funnel of the Venturi nozzle 14 with respect to the second portion 21 of the receptacle 19 in the region of the receiving opening 22.
  • the Venturi nozzle component 18 forming the outlet funnel of the Venturi nozzle 14 is likewise inserted into the second section 21 of the receptacle 19 with a first section 24, which defines the outlet nozzle of the Venturi nozzle 14, with the venturi nozzle component 17 forming the inlet funnel and penetrates the receiving opening 22 of the receptacle 19.
  • the Venturi nozzle member 18 forming the outlet port of the venturi 14 has, besides the first portion 24 defining the outlet port of the venturi 14, a second portion 25 formed on the first portion 24 as a projection, this second portion 25 of the Venturi nozzle member 18 is inserted or inserted into both the first portion 20 of the receptacle 19 and in the second portion 21 of the receptacle 19 from the second side thereof.
  • At least one sealing rib 26 is formed on a peripheral edge of the second portion 25 of the Venturi nozzle member 18, which, when the Venturi nozzle components 17 and 18 are inserted into the receptacle 19, the second portion 25 of the Venturi nozzle component 18 seals against both sections 20 and 21 of the receptacle 19 in the region of the opening formed on the second side of the receptacle 19, so that the gas flow leaving the gas control device 10 via the gas outlet 19 via the first portion 20 of the receptacle 19 in the direction of the second portion 22 of the receptacle 19 and so the venturi nozzle 14, which is provided by the Venturi nozzle components 17 and 18, can be supplied.
  • the housing 11 of the gas control device 10 and the receptacle 19 for the Venturi nozzle components 17 and 18 is a monolithic assembly.
  • the or each sealing rib 26 of the portion 25 of the Venturi nozzle member 18 seals the Venturi nozzle 14 inserted into the receptacle 19 with respect to the receptacle 19 on the first side thereof.
  • the seal 23 seals the Venturi nozzle 14 inserted into the receptacle 19 with respect to the receptacle 19 on the second side thereof. All gas which leaves the gas control device 10 via the gas outlet opening 13, passes exclusively through the Venturi nozzle 14 in the guided from the Venturi nozzle 14 or via the Venturi nozzle 14 sucked combustion air.
  • FIG. 1 As Fig. 1 can be removed, 19 attachment flanges 27 are formed for a fan on the second portion 21 of the receptacle so as to mount a fan on the receptacle 19 for the venturi nozzle 14.
  • Fig. 1 can be used in the gas outlet 13 of the gas control device 10, a component 29, by means of which the size of the gas outlet 13 can be adapted to different gas qualities. Depending on the gas quality, therefore, a component 29 with a differently sized passage opening is arranged in the gas outlet opening 13.
