摘要： 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).
