Patent ID: 7070116

Claim:
An integrated thermostatic valve device comprising a hollowed-out, tubular-shaped body ( 1 ), which has a chamber ( 2 ) which extends from a flange ( 3 ) having holes ( 4 ) for screws that fix the body to an engine housing, the flange having a central opening ( 5 ) that defines a mouth of a chamber, an edge of the mouth provided with a ring-shaped groove ( 6 ) for housing a sealing ring ( 7 ); the hollowed-out, tubular shaped body ( 1 ) having a circumferential ring ( 9 ) from which projects a pair of legs ( 10 b , 10 c ) leading to an upright leg ( 10 a ), forming an inverted “Y”( 10 ), the upright leg having a first end at a level of an opening in the body and having a fixing hole ( 12 ) on a second end thereof at an intersection of the pair of legs of the inverted “Y”, an upside down plate ( 13 ), disposed about the first end of the upright leg, having a ring-shaped central projection ( 14 ) slidable over the upright leg, a pressure spring located between the plate ( 13 ) and the pair of legs of the inverted “Y”, a metal sheet disc ( 17 ) being engaged to an internal lip of a chamber opening for supporting a working element or temperature sensor ( 16 ) of the thermostatic valve, the working element or temperature sensor having a central hole in which a terminal ( 18 ) of the working element or temperature sensor ( 16 ) moves; a pair of vertical blades ( 23 ) connected between the plate ( 13 ) and the working element or temperature sensor ( 16 ); a washer ( 19 ) fixed to an end of the working element or temperature sensor ( 16 ) for supporting a circular sheet ( 20 ) having a turned edge and having a central hole through which the terminal of the working element or temperature sensor is movable in response to temperature changes, a conical pressure spring located between the circular sheet ( 20 ) and a step formed in a body of the working element or temperature sensor.
