on the other and radially protrude from the valve housing 14 cylindrical. Preferably, the gas valves 10 to 13 are called gradual gas valves or step valves, and by means of them the amount of combustible gas flowing from a main gas conduit 18 of the valve arrangement of valves can be adjusted gradually. gas 9 towards the respective gas burners.

The arrangement of gas valves 9 further comprises the main gas conduit 18, which is connected with the gas valves 10 to 13, preferably, with each of the gas valves 10 to 13. Specifically, the conduit main gas 18 is screwed with the gas valves 10 to 13, for which each gas valve 10 to 13 has a clamping element 19 that is arranged between the valve housing 14 and the main gas conduit 18. The element of tightening 19 is screwed with a screw 20 with the valve housing 14 of the respective gas valves 10 to 13.

open state, and figure 4 shows the fixing element 29 superimposed, simultaneously in the open state and in the closed state.

Preferably, the fixing element 29 is made in one piece with the housing device 21 and, in particular, in a piece with the base section 22. The housing device 21 and the fixing element 29 are preferably made of a plastic material, and in one piece as for the material. As also shown in Figures 3 and 4, the fixing element 29 is a tube clamp, which is divided and closed by its perimeter to wrap the gas conduit 25.

The housing device 21 comprises at least one housing section 34 for accommodating at least one valve 10 to 13. Preferably, the number of housing sections 34 coincides with the number of gas valves 10 to 13. Each section of housing 34 has a circular cylinder shaped geometry and is, in particular, tubular. The cylindrical valve housing 14 is housed in the housing section 34 and centered on it. Also, the housing device 21 has elastically deformable grip arms 35, 36, which are configured to partially or completely wrap the gas conduit connection 16 and the thermal element connection 17 of the gas valves 10 to 13. In this way, the assembly of the gas valves 10 to 13 together with the housing device 21 is simplified.

Figures 5 and 6 show the arrangement of gas valves 9 with the fixing element 29, in each case in another schematic view enlarged in perspective. Figure 5 shows the fixing element 29 in the open state, and Figure 6 shows the fixing element 29 in the closed state.

Each fixing element 29 comprises a first grip arm 37 and a second grip arm 38, which are made to wrap the gas duct 25. At least one of the grip arms 37, 38 is elastically deformable and, so preferred, both grip arms 37, 38 are elastically deformable as a spring. The first grip arm 37 has a gear section 39 and the second grip arm 38 has a counter gear section 40, which is configured to engage in the gear section 39 in shape drag. In particular, the counter gear section 40 is configured to engage in the gear section 39.

Figure 7 shows a schematic sectional view of the arrangement of gas valves 9. The fixing element 29 is provided to press a union flange 41 of the gas conduit 25 axially, that is, in the longitudinal direction L of the gas conduit gas 25 against

the gas duct connection 16. To this end, the fixing element 29 may be spring pre-tensioned in the direction of the base section 22 of the housing section 34. On the front side of the base section 22 of the housing device 21 a wing 42 protrudes, next to which the fixing element 29 is positioned. As an example, the 5 wing 42 may be elastically deformable as a spring and be prestressed so that the fixing element 29 presses the flange of union 41 axially against the gas line connection 16.

Since the union nuts 30 to 33 can be dispensed with, it is also possible to assemble the gas ducts 25 to 28 with a reduced available space, in particular with 10 large 10 to 13 gas valves. Gas lines 25 to 28 can be mounted next to gas valves 10 to 13 without additional tools. The complexity of the assembly is reduced and components can be saved, and the assembly of the gas valves 10 to 13 next to the housing device 21 can be performed without additional parts such as screws. The gas valves 10 to 13 can be introduced by quick fitting into the housing device 21. The gas valve arrangement 9 can be provided and mounted next to the cooking hob tray 2 as a pre-assembled construction group, namely, The arrangement of gas valves 9 can be joined by quick or elastic fit with the cooking countertop tray 2, which further reduces the complexity of the assembly.
