Gas regulating fitting
A gas regulating fitting that, in addition to enabling an electronic ignition of the gas flow, also permits a manual ignition. A covering element ( 17 ) is displaceably mounted on the housing ( 1 ) of the gas regulating fitting and, in a first position, covers a tappet ( 10; 14 ), which is provided for actuating a thermoelectric ignition safety valve ( 26 ) and a main valve ( 19 ), and covers a control switch ( 13 ) of a piezoelectric igniting element. When the covering element ( 17 ) is in a second position, an actuation of the tappet ( 10; 14 ), which inevitably occurs when the covering element ( 17 ) is displaced, ensures that the main valve ( 19 ) is located in the closed position. In addition, the control switch ( 13 ) and the tappet ( 10, 14 ) are released in this position in such a manner that an ignition of the gas flow is made possible by a manual actuation thereof.
1. Gas regulating valve with electronic ignition for a gas-heated chimney stove or similar with a thermoelectric ignition locking valve ( 26 ) and a main valve ( 19 ), which jointly serve both as a pilot light and to split the gas flow into components for a main burner and an ignition burner, and which are accommodated with other secondary functional elements in a segmented housing ( 1 ), a tappet ( 10 ; 14 ) located axially to the ignition locking valve ( 26 ) and the main valve ( 19 ) and which projects from a gasbearing chamber of the housing ( 1 ) and can be actuated longitudinally against the force of a restoring spring ( 23 ) via an electromagnet ( 12 ), said gas regulating valve having a masking element ( 17 ) located on the housing ( 1 ), that in an initial position masks the tappet ( 10 ; 14 ) and a pushbutton ( 13 ) of a piezoelectric ignition element, and when the masking element is in a second position the main valve ( 19 ) is in the closed position and the pushbutton ( 13 ) and the tappet ( 10 ; 14 ) are enabled so that the gas stream can be ignited by manual operation.
2. Gas regulating valve electronic ignition in accordance with patent claim 1 , having the masking element ( 17 ) with a link track 18 ),having a pitch which is fixed so that in the second position the main valve ( 19 ) is in the closed position.
3. Gas regulating valve with electronic ignition in accordance with patent claim 2 , having the link track ( 18 ) with notches for both the initial position and the second position of the masking element ( 17 ).
4. Gas regulating valve with electronic ignition in accordance with claim 1 ,having the masking element ( 17 ) located centrally so as to be free to rotate on a pin ( 16 ) with clearances ( 32 ; 33 ), which in the second position release the pushbutton ( 13 ) and the tappet ( 10 ; 14 ).
5. Gas regulating valve with electronic ignition in accordance with claim 1 , having the tappet ( 10 ; 14 ) segmented.
