Patent ID: 8087592

Claim:
A pressure-thermostat ( 1 ) including: a body ( 2 ) having a housing cavity ( 5 ) and a conduit ( 6 ) suitable for containing a fluid; an elastic membrane ( 9 ) arranged for separating in a fluid-tight manner said conduit ( 6 ) from said housing cavity ( 5 ), said elastic membrane ( 9 ) being elastically deformable between a resting condition and a working condition, wherein at least a portion thereof is protruded towards said housing cavity ( 5 ); a thermostat ( 12 ) including a bottom ( 15 ), said thermostat ( 12 ) being movable within said housing cavity ( 5 ) between a first position and a second position; and transmission means ( 34 ) interposed between said elastic membrane ( 9 ) and said thermostat ( 12 ) for transmitting the movement from the elastic membrane ( 9 ) to the thermostat ( 12 ) and vice versa, such that the first and the second positions of the thermostat correspond with the resting condition and the working condition, respectively, of said elastic membrane ( 9 ), said transmission means ( 34 ) being suitable for carrying out a thermal bridge between said elastic membrane ( 9 ) and said thermostat ( 12 ), wherein said transmission means ( 34 ) have a minimum cross section greater than 8 mm 2 .
