A cooking appliance and method of operating the same utilize a multi-level valve system that regulates an output power level of a gas burner for an oven between a maximum output power level and at least one reduced output power level to selectively reduce the output power level of the gas burner during at least a portion of an oven warm-up operation, e.g., to improve burner operating characteristics during the oven warm-up operation.

A cooking appliance and method of operating the same utilize a variable electromechanical valve to regulate an output power level of an oven broiler gas burner for a cooking appliance. Among other benefits, in some instances broiler control during cooking may be decoupled from oven warm-up, and in some instances support may be provided for automatic and/or user controlled broiler output power levels and/or automated broil profiles.

The present invention provides a gas safety device using low power to control high flow, which includes a controller, a differential pressure regulating valve, and a driver, the controller can control if the gas can flow into the differential pressure regulating valve, the differential pressure regulating valve is connected to the controller, and can control if the gas can flow out for burning according to the gas pressure changes, the driver uses a drive piece to drive a micro switch lever inside the controller, so that the controller can output gas, thus, the present invention can control high gas flow with low power while maintaining safe usage of the gas.

Embodiments of a pressure regulator for delivering gas to a cooking station. The pressure regulator includes a body defining a gas inlet and a gas outlet. The body also includes a knob coupled to the body, the knob manually rotatable about an axis defined by the knob. The pressure regulator also includes a lever arm within the body. The lever arm extends to an end portion positioned adjacent the gas inlet, the lever arm pivotable via rotation of the knob such that rotation of the knob adjusts gas flow pressure through the body between about 11 inches of water column and about 8.5 inches of water column.

Regulating valve for a gas cooking appliance, comprising a valve body with an inlet conduit and at least one outlet conduit, and a rotating disc arranged between the inlet conduit and the outlet conduit, comprising a plurality of connecting holes for regulating the gas flow, more than one connecting hole overlapping with an outlet hole of the outlet conduit, and the rotating disc comprising a main series of connecting holes increasing in size in the direction of increasing gas flow. There is an intercalated hole between successive holes of the main series and after each hole of the main series, the size of each intercalated hole being smaller than the size of the preceding contiguous hole of the main series.

An inlet body for a fluid injector for a turbomachine. The inlet body includes a casing defined by an internal surface and a seal valve housed inside the casing. The valve includes a sealing member including an intake duct, and internal duct into which the intake duct opens, and a seat for the sealing member. The seat defines an opening over a fluid path towards the internal duct. The internal surface includes a recess which defines at least partially a chamber communicating with the opening and with the intake duct.

A regulating valve with at least one gas outlet conduit and a housing having at least one outlet hole in fluid communication with the outlet conduit; a rotating disc arranged in the housing; a spring axially retaining the rotating disc in the housing; and sealing means surrounding the at least one outlet hole. The sealing means includes a gasket having a closure member associated with each outlet hole, surrounding the same, and at least one attachment arm attached to the at least one closure member. The attachment arm including at least one protuberance, with the rotating disc being supported on the closure members and on the protuberances when it presses on the gasket.

A method for calibrating a position of a control valve within a gas valve assembly for controlling fuel flow to a combustion appliance. The method may include moving the control valve to a second end stop, moving the control valve from the second end stop to a first end stop while counting a number of steps traveled by a stepper motor driving the control valve, and comparing the counted number of steps traveled from the second end stop to the first end stop to a reference value stored in a memory of the controller. If the counted number of steps does not match the reference value, the gas valve assembly may be placed in a lockout mode.

A gas valve for a cooking appliance is provided and includes a valve housing defining a valve chamber therein. A plug is disposed within the valve chamber. A valve stem interacts with the plug such that rotation of the valve stem correspondingly rotates the plug to selectively permit a flow of gas through the gas valve. The valve stem is axially translatable between a locked position wherein rotation thereof is inhibited and an unlocked position wherein rotation thereof is permitted. A first spring exerts a compressive force against the valve stem, toward the plug, to bias the valve stem into the locked position. A second spring exerts a compressive force against the plug in order to seat the plug within the valve chamber regardless whether the valve stem is in the locked or the unlocked position.

An inlet body is for a fluid injector for a turbomachine. The inlet body includes a casing and an inlet nozzle, housed inside the casing, that serves as a seat for a mobile sealing member. The inlet nozzle includes a central duct for the fluid and an annular rim surrounding the central duct. The annular rim includes a housing for a gasket. The housing is defined by a bottom wall, an opening opposite the bottom wall, and two opposite walls which each extend between the bottom wall and the opening. The walls are tilted towards each other in the direction of the opening.
