| 181 | APPARATUS AND METHOD FOR CONTROLLING THE FLOW OF A FLUID | PCT/GB2013052949 | 2013-11-08 | WO2014083312A3 | 2014-11-27 | BEG MIRZA NAJAM ALI; SARSHAR MIR MAHMOOD; MORRISON COLIN NEIL |
| An apparatus for controlling the flow of a fluid includes a LP fluid inlet (18) and a LP fluid outlet (9) connected to a flare/vent system. A LP flow line (20) connects the LP fluid inlet (18) to the LP inlet 6a of a jet pump (6). A supply of HP fluid is connected to jet pump inlet (6b), and a MP line (8) is connected to jet pump outlet (6c). A control unit (28) is configured to control operation of first and second LP flow control valves (4,3) according to signals received from a flow meter (12), so that LP gas is diverted from the flare system to the LP inlet (6a) of the jet pump for pressurisation. | ||||||
| 182 | THERMOSTATIC VALVE | PCT/IB2013059530 | 2013-10-22 | WO2014064605A3 | 2014-09-12 | BESATI DAVIDE; DUGNANI MASSIMO; PEDRETTI LUCA; TAPPA MAURO; VALZI GIUSEPPE |
| The invention relates to a thermostat (10) for cooking appliances powered by gas, said thermostat (10) comprising a body (20) within which there are formed an inlet conduit (23) and an outlet conduit (24), suitable to receive a gas flow from a supply source and to supply such a gas flow to a gas burner, respectively, as well as a chamber (25) with a substantially cylindrical shape arranged in fluid communication with said inlet conduit (23). The chamber (25) is also arranged in fluid communication with said outlet conduit (24) either directly, through a main opening (70) formed at one end thereof, or indirectly, through a secondary conduit (71) that is formed in the body (20) of the thermostat (10) and reaches the outlet conduit (24) bypassing said main opening (70), said main opening and secondary conduit (70, 71) being respectively dimensioned for a maximum and a minimum flow rate of gas. The thermostat (10) further comprises a valve (80) for adjusting the gas flow rate, the valve being coaxially fitted in the chamber (25). The position of the valve (80) is controlled by an expandable member (53) of a thermostatic bulb (50) of the thermostat (10) and the valve is axially deformable beyond a predefined load threshold. Thanks to this configuration, the valve allows to compensate for dilations of the expandable member (53) under a normal operation condition, as well as to absorb axial forces exerted by the thermostat (10) knob when it is rotated in order to switch off a burner driven by the thermostat, thus minimizing the risk that these forces damage even irreparably the expandable member (53) of the thermostatic bulb (50). | ||||||

| Gas burner for a household appliance, which comprises a casing (5), a thermocouple (4), an injector (2) fixed to the casing (5), and a thermoelectric safety actuator (20) adapted to open or close the passage of gas towards the injector (2). The actuator (20) is arranged fixed to the casing (5) and comprises a body (21,22), an inlet gas conduit (23), an outlet gas conduit (25) connected to the injector (2), an electromagnet (36) housed in the inside of the body (21,22) and arranged connected to the thermocouple (4), a tilting arm (38) that has a frame (37) connected to it and a sealing member (35), the arm (38) tilting between a rest position in which the passage of gas towards the outlet conduit (25) is closed and an activation position in which the electromagnet (36) is energized and the passage of gas open. | ||||||

| The invention relates to a gas burner arrangement (3 - 5) for a hot plate (2), said arrangement comprising at least two gas burners (7 - 10) and a common gas-regulating valve (6) for regulating a volumetric flow rate of gas to the at least two gas burners (7 - 10). | ||||||
| 185 | GAS COOKER, GAS FLOW CONTRL DEVICE AND METHOD THEREOF | PCT/EP2013060859 | 2013-05-27 | WO2013178582A3 | 2014-05-01 | KOCH THOMAS; LI XINGZHOU; REDONDO MORITZ JOSE; WU JINHUA |
| The present invention provides a novel gas flow control device for a gas cooker, including a fuel gas inlet and a fuel gas outlet, and also including a control module and at least one control valve; the control module is used for opening the control valve; when the control valve is opened, gas sequentially flows through the fuel gas inlet and the control valve, and then flows toward the fuel gas outlet, and the control valve alternately opens and closes an airflow passage by which the gas flows through the control valve. In this way, even if the gas flow is unstable, by means of the technical solution of the present invention, the gas flow finally flowing to the burner is relatively stable. | ||||||
| 186 | GAS REGULATING VALVE USED IN GAS STOVE, ELECTRICALLY CONTROLLED GAS REGULATING VALVE USED IN GAS STOVE, AND GAS STOVE | PCT/IB2012056727 | 2012-11-26 | WO2013080116A3 | 2014-03-06 | WU JINHUA; REDONDO MORITZ JOSE; LI XINGZHOU |
| A gas regulating valve used in a gas stove includes a valve body (11), and a rotating disk (12) in plane contact with a surface of an inner cavity of the valve body (11) and capable of rotating relative to the surface of the inner cavity of the valve body (11). The valve body (11) is provided with a gas inlet (111) and a gas outlet, and a contact surface of the valve body (11) and that of the rotating disk (12) are fitted in a sealed manner. The rotating disk (12) has a connection channel (121) capable of selectively connecting or disconnecting the gas outlet on the valve body (11) and the inner cavity of the valve body (11) or changing a communication degree therebetween when the rotating disk (12) rotates. The present invention further provides an electrically controlled gas regulating valve used in a gas stove, and a gas stove including the gas regulating valve or the electrically controlled gas regulating valve. The technical solutions of the present invention solve the problem that a plug valve used in an existing gas stove is inconvenient to process and has a high cost. | ||||||

| A stove (1) has a fuel reservoir (2) which communicates via fuel supply line (8) with a burner (4). A stop valve (3) in the fuel supply line (8) controls fuel supply from the fuel reservoir (2) to the burner (4). A normally-open emergency shut-off valve (10) in the fuel supply line (8) is operable to close the fuel supply line (8) if the fuel pressure rises a preset amount above a normal operating pressure due to overheating of the fuel reservoir (2) for example. | ||||||
