摘要:
A digital gas cooking appliance is disclosed. The digital gas cooking appliance has the ability of self-initiating an automatic calibration process to determine an optimum valve position to be used for an electromechanical valve when igniting a gas cooking element by performing a plurality of ignition sequences for the gas cooking element at a plurality of respective valve positions of the electromechanical valve. During each of the plurality of ignition sequences, a respective ignition duration between a start of the respective ignition sequence when an igniter is active and the electromechanical valve is open, and a flame is detected by a flame detector, may be determined.

Magnet-thermocouple for the fail-safe safety supply of gas to burners or the like, in particular of fail-safe safety control for domestic cooking devices, comprises: at least one gas burner, which gas burner is connected to a gas supply source by flame-regulating means and by means of a safety valve driven by a flame presence sensor consisting of a thermocouple, said safety valve having an open condition, wherein said supply source supplied said burner, and a closed condition, wherein the gas passage is interrupted and wherein the thermocouple, in the presence of a flame, generates an electrical signal constituting the drive signal for the passage of said safety valve from an open condition to a closed condition, and vice-versa, of said safety valve, whereas a further drive signal generator and power supply of said safety valve is provided, for the temporary and alternative supply of the safety valve during the flame ignition step heating the thermocouple, to the temperature generating the drive signal. According to the invention, the signal generator and power supply comprise power limiters to limit the signal generated and an automatic deactivating unit whenever the power supply is overloaded for a predefined amount of time, the power necessary for the drive signal of the safety valve being greater than the one determined by the limiters.
摘要:
An assembly for controlling the flow of a gas to a gas burner. The assembly including a rotational regulating valve and an electromagnetic safety valve. The regulating valve is rotational between a first angular position corresponding to a closed position and a second angular position corresponding to an open position. The safety valve includes a valve member that translates axially between a first axial position corresponding to a closed position and a second axial position corresponding to an open position. An operating shaft is operably coupled to the rotational regulating valve and to the electromagnetic safety valve and is rotatable between angular positions corresponding to the closed and open positions of the rotational regulating valve and is axially translatable between axial positions corresponding to the closed and open positions of the valve member of electromagnetic safety valve, axial translation of the operating shaft is not permitted when the angular position of the operating shaft corresponds to an open position of the rotational regulating valve.

A cooking device is provided. The cooking device includes a burner body having a nozzle to supply a gas, a burner head provided above the burner body, and having a mixed gas chamber in which air and the g/re introduced. a burner cap provided on the burner head, a flame remaining chamber provided at the burner head and separated from the mixed gas chamber, and a flame detection unit to pass through the burner head and located at the flame remaining chamber.
摘要:
A thermocouple connector adapted to an electromagnetic valve, the electromagnetic valve having a quick-connect terminal with a base. The connector has an inner surface that faces the base when the connector is inserted transversally to the connection terminal. The connector includes guiding means that projects out in relation to the inner surface, extending longitudinally in the direction of insertion, adapted to guide the transverse insertion of the connector. The connector is configured to come into contact with the base through the guiding means.
摘要:
A gas heater (10) includes heater burner (16). Heat is generated by the ignition of gas supplied to the burner via conduits (20). A solenoid gas safety valve (22), when provided with a threshold electrical current, is maintained in an open condition allowing passage of gas to the burners. When not provided with that threshold current, the valve is closed, preventing the passage of gas. An electrical current generator (28) includes spaced apart thermocouple devices (30, 32). Due to a combined electrical current generation by the thermocouples, the current generator can generate electrical current at least said threshold current even if any one of the thermocouple devices does not generate the threshold electrical current

A pilot burner assembly for easy removal of a thermo-electric or other device is disclosed. In an illustrative embodiment, a pilot burner assembly may include a bracket and a resilient clip, which together, help maintain at least some of the pilot burner components in a desired configuration.
摘要:
The invention relates to a valve arrangement for a gas installation comprising a valve body with at least one gas inlet, whereby at least one gas outlet is assigned to a gas inlet and, more particularly whereby one gas outlet can be closed by means of a medium-controlled or flame-controlled safety valve element, whereby one gas outlet be reduced in cross-section and/or closed by means of a valve element arranged on a non-rotating shaft, whereby the actuator (6) of the valve element (10) is in the form of a linear motor (6) on the shaft of which the valve element (10) is directly arranged. The invention also relates to a joint valve body for multiple adjacent identical valve arrangements in which the gas inlets (3) of all valve arrangements are connected to a joint gas pipeline (3) more particularly extending in the longitudinal direction of the entire valve body (1), whereby perpendicularly to the axis of the joint gas supply pipeline (3) bored holes (B1-B5) are arranged, which at least from holders for safety valve arrangements (2) and actuators (6) as well as gas outlets (5), more particularly also for forming a by-pass pipeline (18), in which, more particularly, a gas nozzle (19) can be used.
摘要:
A convertible two-stage pressure regulator in which a main valve regulates fluid flow between an inlet and an outlet in response to a control pressure produced by first and second regulator valves arranged in parallel, the control pressure depending on the outlet pressure and the forces applied by compression springs to diaphragms carrying the first and second regulator valve closure elements. An electrically operated valve is provided for selectively disabling the second regulator valve whose regulator spring applies a higher force than the spring of the first regulator valve. The compressions of the regulator valve springs are coordinately varied by a manually operable selector mechanism for convening between natural and LP gas usages.
摘要:
A control system, a control device therefor and methods of making the same are provided, the control device having an axially movable shaft for moving a movable valve into its latching position with an electromagnetic unit and also being rotatable from a first position thereof to a second position thereof to place and hold an electrical switch in an operating condition thereof, the switch being in series with the electromagnetic unit so that the electromagnetic unit can not have an electrical current flowing therethrough unless the switch is in the operating condition thereof.
