Abstract
The thermostatic gas valve comprises a body (2) wherein three cylindrical cavities of parallel axes (8,9,10) contain the flow valves (6,20,13,14) and a thermostatic bellows (11), a single rotating knob (7) having a cap (7a) and an inner cylindrical member (7b) with relative axial movement, and four chambers (30,31,32,33) communicating a respective valve with the two pairs of gas inlets (34,34') and outlets (35,35') located for access thereto from the front of the valve. The guide means (23,40) for the central shaft (8') of the knob (7) are combined with the guide means (15a,15b,15c,41) for the body cover (15) located underneath the knob (7), to find its different angular positions. The obturators of the minimum and proportional gas flows are formed in a single piece by two integral parts.
