Abstract: The invention relates to a valve assembly for a cooling system. The cooling system has a container containing liquid nitrogen under pressure which is to be distributed in vapor form to an enclosed space to be cooled. The valve assembly includes a main valve and pressure operated means for operating the main valve which means utilizes the vapor pressure of the nitrogen in the container referred to above. Two auxiliary valves are provided which are actuated in unison in response to temperature changes in the space to be cooled. The auxiliary valves control the application of pressurized nitrogen vapor to the main valve operating means.

Abstract: The invention relates to a refrigerant valve assembly of the type in which the actuating spindle is loaded at one of its ends by a membrane pressure element and the other end by a spring. The membrane end of the spindle is surrounded by a bellows and it is the chamber which surrounds the bellows in which the interest is. That chamber is substantially sealed from the atmosphere but a first fluid passage connects it with the atmosphere. A second fluid passage which has fluid communication with the downstream side of the valve has a Venturi insert and intersects the first fluid passage. The Venturi produces an aspirating effect which draws moisture ladened air out of the bellows chamber referred to above.

Abstract: The invention relates to a refrigerant valve assembly of the type in which the actuating spindle attached to the valve is loaded at one end by a diaphragm pressure unit and at the other end by a spring. The diaphragm pressure unit includes a diaphragm with first and second chambers on opposite sides of the diaphragm. A bellows surrounding the diaphragm end of the spindle is disposed in one of the chambers and fluid communication is provided between the valve working chamber and the space internally of the bellows. Fluid communication is also provided between chamber in which the bellows is disposed and the valve working chamber. The object is to provide a dry gas in the chamber in which the bellows is disposed to prevent icing of the end of the spindle due to condensation.
