ABSTRACT:
A temperature sensitive valve having a body with an internal valve chamber being open through said body, an inlet extending into the valve chamber, a control outlet communicating with said valve chamber, and a bleed outlet communicating with said valve chamber, a bonnet having a bore secured to said body in surrounding relationship to the opening of the valve chamber through the body, a control sleeve positioned in said valve chamber and in said bonnet bore, means for sealing between the control sleeve and the interior of the valve chamber above and below the entry of said inlet into the valve chamber, said control sleeve defining a first valve seat in its lower portion, a second valve seat surrounding the entrance of the bleed outlet into said valve chamber, a valve member extending through said valve sleeve and having valve seat engaging surfaces for engaging said first and second valve seats, a first temperature sensitive material supporting said valve member in position out of engagement with said first valve seat, a second temperature sensitive material supporting said control sleeve in a first position and allowing it to move to a second position when exposed to temperature above a preselected temperature, said first temperature sensitive material upon reaching a elevated temperature which is less than said preselected temperature to release support of the valve member so that it moves out of engagement from said second valve seat and into engagement with said first valve seat to close flow between said inlet and said control outlet and open flow between said control outlet and said bleed outlet, said second temperature sensitive material releasing support of the control sleeve so that it moves to bring said valve member into engagement with said first valve seat when it reaches said preselected temperature and means biasing said valve member and said control sleeve so that excess pressure in said control outlet will move said control sleeve to open said second valve seat and allow such pressure to be bled from the valve chamber.
