| 摘要 |
<p>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 flows into 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 one piece valve (80) for adjusting the gas flow rate the valve being coaxially fitted in the chamber (25) and guided by its peripheral walls. Thanks to these features, the structural configuration of the thermostat body and its conduits is much more compact functional and cheap than the structural configuration of thermostats known in the art.</p> |
