In dem Stellventilkörper (64) ist zentral das Regelventil (49) angeordnet mit einem im Stellventilkörper ausgebildeten Regelventilsitz (65) und einem bewegbaren Regelventilkörper (64), wobei der Regelventilkörper (64) zur Verstellung mit dem Thermostat-Antrieb (34) verbunden ist.

The invention relates to an electromagnet comprising an impact-absorbing spring (1.10) which prevents contractions likely to occur in case the user applies too much force on the handle within gas taps having an electromagnet assembly which are used in domestic cooking appliances, wherein said spring can be located in different areas in the electromagnet. Gas taps having an electromagnet assembly which are used today generally consist of a body having gas passageways; a male regulating said gas passageways; a handle enabling the user to close said gas passageways; an electromagnet for opening/closing said gas passageway; together with a pin (1.7) transferring the movement from the handle to the electromagnet; a union fixing the electromagnet in the housing thereof within the tap; and a cover protecting the tap against external factors. Since there is no part which will absorb the force applied by the user within these taps, the system cannot be fully protected and contractions may occur in the tap in case of excessive load. According to the invention the system will be protected against excessive load thanks to the spring located at the end portion of the electromagnet or located in the housing thereof at the end portion of the electromagnet.

A mixing block (380) is disclosed for preparing a premix of combustible gas and air to be supplied to a flame detection electrode (382) or to an ignition electrode. The mixing block comprises:

- an outlet channel (384) for guiding a premix of combustible gas and air out of the mixing block,

- at least one inlet (384) for supplying air into the mixing block,

- at least two connections (388, 389) to connect different supplies of combustible gas to the mixing block,

- channels (392, 393) inside the mixing block to guide combustible gas from each of the at least two connections (388, 389). The at least two connections (388, 389) are connectable via these channels (392, 393) towards the outlet channel (384) in the mixing block,

- a switch (396) for selecting from which of the at least two connections (388, 389) a flow connection is realized to the outlet channel (384).

The gas / air mixture supplying tubes of the detection electrodes (382), downstream the outlet channel (384), are to be placed proximate an infrared radiation burner, from which the flame can propagate to the tube exits, thereby igniting the fuel/air mixture leaving them. These flames are to be recognised then for the ionisation current through the flame detection electrodes (382).

The invention relates to a male (1.2) inside the gas tap (1) that allows opening/closing gas passage and adjusting the amount of gas passage in the meantime within gas operated domestic cookers, said male (1.2), which is located in the center of the gas tap (1) serving to enable the gas to pass at a certain flow rate, and thus allowing the flame to burn at a high or low amount and being provided with a V-shaped channel (1.2.1) with a slot form for full gas passage.

An apparatus includes a control valve (130) for regulating fuel flow. The apparatus includes a burner (190) and a valve assembly (120). The valve assembly (120) includes a housing, which defines a first fuel input for receiving a first fuel from a fust fuel source and a second fuel input for receiving a second fuel from a second fuel source. The housing defines a first fuel output for directing fuel toward the control valve, and a third fuel input for receiving a portion of either the first fuel or the second fuel from the control valve. The housing defines a first egress flow path and a second egress flow path, each for directing fuel to the burner. The apparatus includes a valve body configured to selectively permit fluid communication between the first and second inputs and the output and between the third input and the egress flow paths.

A gas tap (2) used in domestic cooking appliances, which can be used in touch-sensitive gas control systems allowing touch control of the gas flow passing through gas taps, said gas tap comprising a body (2.1), a gas inlet 2.2), a gas outlet (2.3), a male (2.4), a pin (2.5), a gasket (2.11), a gearbox (2.12), a servomotor (2.14), a gear (2.15), a pinion (2.16) and a gear system cover (2.13) as well as an electromagnet (2.6) directly connected to a control panel (1) by means of a connecting cable (2.7), said electromagnet permiting gas passage or stopping gas flow in accordance with the information coming from control panel.

The invention discloses a safety cooktop gas tap (1) with two outlets of lighter weight and smaller size, suitable for use in such domestic cooking appliances as cookers and ovens. The said gas tap (1), in most general terms, consists of a gas inlet (1.6) and two gas outlets (1.7, 1.8), a single-piece body (1.1), a male (1.4) positioned in the said body (1.1), a lid (1.3), a shaft (1.2) and a safety valve (1.5); wherein the said safety valve (1.5) is angularly positioned such that the angle B will be between 40° and 60°; and wherein a space (1.18) is provided between the first gas outlet (1.7) and the second gas outlet (1.8), which are located in the same plane.

Gas manifold (1) for a cooking device that includes a distributor conduit (2) of a gas flow (Q) formed by a cylindrical pipe of a certain uniform diameter (D1) fitted with a plurality of regulation taps (3), and that is provided with a manually operated emergency tap (4) at the gas inlet, with a cut-off valve (10) disposed in parallel in relation to the distributor conduit (2), in which a seal device (13) of the passage of the flow (Q) is intercalated in the interior of the conduit(2) between an inlet (8) and an outlet (9) of the emergency tap (4), as a result of which all the flow (Q) is diverted to the emergency tap (4), thereby bypassing the seal device (13). The sealing of the distributor conduit (2) is made by means of a circular disc (14) and a ring sealing gasket (15).

A gas tap (2) used in domestic cooking appliances, which can be used in touch-sensitive gas control systems allowing touch control of the gas flow passing through gas taps, said gas tap comprising a body (2.1), a gas inlet 2.2), a gas outlet (2.3), a male (2.4), a pin (2.5), a gasket (2.11), a gearbox (2.12), a servomotor (2.14), a gear (2.15), a pinion (2.16) and a gear system cover (2.13) as well as an electromagnet (2.6) directly connected to a control panel (1) by means of a connecting cable (2.7), said electromagnet permiting gas passage or stopping gas flow in accordance with the information coming from control panel.
