An apparatus for heating water comprises a main burner, a pilot burner, a valve assembly with a main valve and a pilot valve having a shutter, a magnetic thermoelectric safety assembly with a thermocouple device holding the pilot valve open in the presence of a flame in the pilot burner, a button member mounted on a rod that is slidingly guided in the valve assembly and an electrical ignition member supplied via an electrical connection circuit, a switch device in the circuit being designed to be switched by means of the button member so as to close the electrical circuit when said button member is pressed in order to carry out actuation of the magnetic assembly so as to open the passage of gas through the pilot valve towards the pilot burner and to ignite the pilot flame by means of the sparks generated by the ignition member.

An appliance includes a first gas-burning heating element, a first gas path extending from an inlet to the first heating element, and a first solenoid valve positioned within the first gas path. The appliance further includes a second gas path extending from upstream of the first solenoid valve to the first heating element and supplying a base gas flow to the first heating element. A controller is electronically coupled with the first solenoid valve for controlling a supplemental flow of gas through the first gas path to the first heating element such that the supplemental gas flow combines with the base gas flow to achieve a total gas flow. The controller controls the supplemental flow to adjust the total gas flow by pulsing the first solenoid valve at a first rate corresponding to a desired rate of the total gas flow to the first heating element.

Gas circuit (1) for a kitchen appliance (2) comprising a gas rail (3) with a gas inlet (4) for connecting said gas rail (3) to a gas source (5) and with at least one gas outlet (6), said gas circuit (1) further comprising a gas tube (7) for providing gas from said gas outlet (6) to a gas hob (8), and said gas circuit (1) further comprising a gas valve assembly (9) connecting said gas tube (7) to said gas outlet (6) of said gas rail (3) in a flow conducting manner, said gas valve assembly (9) comprising a gas valve (10) with a valve body (11) and fixation means (12) fixing said valve body (11) to said gas rail (3) such that said gas valve (10) is supported by said gas rail (3), characterized in that said fixation means (12) comprise a first spring member (13a) looping around said gas rail (3) and/or said valve body (11), thereby resiliently bracing said gas valve (10) and said gas rail (3).

A gas valve unit for controlling a gas throughput routed to a gas burner of a gas appliance includes a valve housing, an actuation shaft which is able to set an opening cross section of the gas valve unit, and a stop valve. A linearly-displaceable connection element transmits a movement of the actuation shaft to the stop valve. The connection element has a plastic bend forming an overpressure protection.

The invention relates to a gas valve unit, comprising a valve body surrounding an inner chamber in a sealing manner; an inlet part; at least one gas outlet in connection with the inner chamber to conduct gas via an outlet channel; a stationary disc member dividing the inner chamber; a rotating control disc member which is superimposed on a corresponding rear wall of the stationary disc member from an inner wall and mounted on a lower part which extends into the inner chamber of a control rod extending out from the body; also an elongated cavity formed in the inner wall of the control disc member and aligned to direct the gas flow to the through hole in an operational position.

A gas distribution assembly that includes a valve mounted on a distribution duct. According to one implementation the body of the valve is supported on the duct by support having a base and a plurality of arms extending from the base. The arms have surfaces that rests on projections of the valve body. A fixation device is furthered used to secure the support to the valve body. The support is configured to hold the valve body on the duct in the event the fixation device fails to secure the support to the valve body.

According to one embodiment a gas distribution assembly is provided that includes a gas distribution duct and at least one gas regulating valve mounted on the gas distribution duct. The valve is secured to the duct by use of a support supported on the duct and attachment means for attaching the valve to the support. According to one embodiment the attachment means comprises a screw threaded into a threaded sleeve and also into a threaded hole in the body of the valve. The support includes a through hole through which the sleeve passes and the sleeve includes a flange at one end that rests on the support in an area that surrounds the through hole. An end of the sleeve opposite the flange resides adjacent the threaded hole in the body of the valve.

According to one embodiment a gas tap is provided that includes a manually operable shaft having a first end coupled to a regulating element and a second end configured to be coupled to a knob that can be operated by a user. The shaft includes a first locking element, and the gas tap includes a second locking element. The shaft is rotational between an initial angular position and a final angular position, and is axially movable when it is arranged in the initial angular position between a first axial position in which the first locking element and the second locking element cooperate with one another, preventing the shaft from being able to rotate, and a second axial position in which the shaft is able to rotate. The user has to pull on the shaft in order to move it from the first axial position to the second axial position.

A control gas ball valve for high pressure gas cooking appliances provides a linear surface slot along its rotation direction. When turned by a control knob and enters a gas inlet, the said surface slot is able to channel gas input to a hole that connects said surface slot to the center of the valve ball. The gas in the center of the valve ball is directed away to a burner for cooking purposes. The said linear surface slot is able to provide constant flowrate slope for continuously variable power adjustment and a maximum power plateau. These are the most desirable features in residential cooking.
