Abstract
An integrated evaporator and thermal expansion valve assembly for use in a refrigeration system. An evaporator includes a housing defining an inlet header and an outlet header. A valve is mounted on the housing in communication with the inlet header for controlling the flow of refrigerant to the evaporator of the refrigeration system. A pressure and temperature resonsive sensing bulb assembly is mounted on the housing in communication with the outlet header for responding to the superheat temperature in the outlet header of the evaporator for opening the valve when the superheat temperature increases and for responding to the pressure in the refrigeration system for closing the valve when the pressure increases to offset a portion of the effect of the temperature response on the valve. A coupling extends through the evaporator housing between the inlet and outlet headers for operatively interconnecting the pressure and temperature responsive bulb assembly to the valve as a function of the responses of the pressure and temperature responsive bulb assembly.
