The invention relates to an actuation device of a gas distribution valve connected to a burner provided with a control thermocouple of the flame presence, said valve ( ) comprising: a gas inlet duct ( ); two or more gas delivery ducts ( ); gas interception means ( ) controlling selectively said inlet duct ( ) and said delivery ducts ( ), said means can be actuated through axial movement of a stem ( ) belonging to said valve; electrical means ( ) cooperating with said thermocouple and said interception means of the gas inlet duct. Said device comprises a flexible metal wire ( ) sliding inside the sheath and fixed at one end ( ) to said stem ( ) of said valve ( ) and at the other end ( ) to a control lever ( ) rotatable relative to a support plane ( ) according to discreet positions ( ) corresponding to the various positions of said interception means.

A flame atmosphere analyzer is described and comprises a tube, in which an air-gas intake and mixing chamber is defined, a gas-supply nozzle, and primary combustion-air supply means opening into the intake chamber, as well as a flame burner comprising at least one flame jet which is in flow communication with the intake and mixing chamber in order to supply an air-gas mixture formed in the chamber. The primary air-supply means comprise at least one duct which has a first end in flow communication with the intake chamber and which is open at the opposite, second end in order to take in primary combustion air in a position remote and at a predetermined distance from the intake chamber in the tube. A water-heating device including the above-mentioned flame atmosphere analyzer is also described.

A safety and regulation valve unit for a gas installation, particularly a heating installation, comprises a duct through which the fuel can flow between an inlet and at least one outlet. An on-off fuel-valve is interposed in the duct between the inlet and the at least one outlet, and there is a movable device for controlling the valve as well as an actuator acting on the movable device in order to move it towards a first operative position in which it cooperates with the on-off valve in order to put the inlet into communication with the outlet. The actuator comprises a reversible motor with a rotor connected to a male-and-female screw coupling acting on the movable device to translate it towards the first operative position and to control the on-off valve.
