Abstract:
Control system for controlling the pilot flame of a combustible gas device, which includes a pilot burner, a main burner, and a valve assembly, which includes a pilot valve that allows/intercepts a flow of gas directed towards the pilot burner, and a main valve that allows/intercepts a gas flow to the main burner, the valve assembly moveable between a closed OFF state, a PILOT state, and an ON state, where gas flows to the main burner. The control system includes a detection device that generates a state signal, and a control unit including a timer, the control unit is operatively connected to the detection device to receive a state signal and to an actuator to close the valve. The control unit starts the timer when the state signal represents the PILOT state, and actuates the actuator for the pilot valve to close it when the timer reaches a preset limit.

Claim (Index 1):
Control system for controlling the pilot flame of a combustible gas device, said gas device ( 200 ) comprising:\n a pilot burner ( 1 ) for generating a pilot flame, a main burner ( 2 ) for generating a main flame, and a valve assembly ( 300 ), comprising a pilot valve ( 3 ) that is arranged upstream of said pilot burner ( 1 ) in order to allow/intercept a flow of gas directed towards said pilot burner ( 1 ), and a main valve ( 4 ) that is arranged upstream of said main burner ( 2 ) in order to allow/intercept a flow of gas directed towards said main burner ( 2 ), wherein the state of said valve assembly ( 300 ) can be moved between an OFF state, in which said pilot valve ( 3 ) is closed, a PILOT state, in which said pilot valve ( 3 ) is open and said main valve ( 4 ) is disabled to allow a flow of gas to flow towards said main burner ( 2 ), and an ON state, in which said pilot valve ( 3 ) is open and said main valve ( 4 ) is enabled to allow a flow of gas to flow towards said main burner ( 2 ), said control system ( 100 ) comprising: a detection device ( 19 ) adapted to detect at least the PILOT state of said valve assembly ( 300 ) and to generate a state signal, which represents the detected state of said valve assembly ( 300 ), a control unit ( 20 ) comprising a timer ( 24 ), said control unit ( 20 ) being operatively connected to said detection device ( 19 ) so as to receive said state signal, and to an actuator ( 10 ) for said pilot valve ( 3 ) in order to close it, wherein said control unit ( 20 ) is configured to: start said timer ( 24 ) when the state signal received by said detection device ( 19 ) represents the PILOT state, and actuate said actuator ( 10 ) for said pilot valve ( 3 ) in order to close said valve when the time measured by said timer ( 24 ) reaches a preset limit, thereby extinguishing the pilot flame.
