expansion valve the manner of assembling the expansion valve of the eighth embodiment will be now described the evaporator 7 is formed integrally with the valve casing 3 the high pressure and low pressure refrigerant pipes 5 and 6 and the outlet pipe 12 portions of the low pressure refrigerant pipe 6 and the outlet pipe 12 extending parallel to the front face of the evaporator 7 are located at an equal distance from the front face while a portion of the low pressure refrigerant pipe 6 joined integrally with the valve casing 3 in alignment therewith is tilted outward in a direction away from the front face of the evaporator 7 to assemble the expansion valve first the expansion valve unit 2 is inserted into the valve casing 3 as indicated by arrow 48 in this case the expansion valve unit 2 is inserted into the valve casing 3 in a manner such that the high pressure refrigerant passage 18 in the body 17 is aligned with the high pressure refrigerant pipe 5 and that the pipe receiving portion 47 of the temperature sensitive chamber 13 is orientated in the same direction as the outlet pipe 12 subsequently the clip 4 is attached as indicated by arrow 49 to fasten together the temperature sensitive chamber mount 16 of the inserted expansion valve unit 2 and the flange 34 of the valve casing 3 and finally the tilted portion of the low pressure refrigerant pipe 6 is raised to an upright position as indicated by arrow 50 so as to be parallel with the front face of the evaporator.
