摘要： An expansion valve 1 comprises a prism-shaped body 10, and a valve chamber 20 is formed within the body 10. Refrigerant supplied from a compressor flows into the valve chamber through a passage 22, passes between a valve means 42 and a valve seat 23, and travels toward an evaporator through a passage 24. Refrigerant returning from the evaporator enters the body 10 through a passage 26, and after the refrigerant temperature information is transmitted to the operating shaft 40, the refrigerant flows out through a passage 28 toward the compressor. Passages 22 and 28 open to a first side surface of the body, and passages 24 and 26 open to a second side surface orthogonal to the first surface. Such structure improves the degree of freedom for mounting the expansion valve 1.

摘要： An expansion valve 101 comprises a substantially prismatic-shaped valve body 301 made of aluminum alloy. On the valve body 301 is formed a first passage 32 through which a liquid-phase refrigerant travels towards an evaporator, and a second passage 34 through which a gas-phase refrigerant travels from the evaporator toward a compressor. On the upper portion of the valve body 301 is mounted a power element portion 36 for driving the valve mounted in the middle of a first passage 32. On the side surfaces 301a of the valve body 301 are formed protruding portions 301c, and to the protruding portions, penetrating holes 50 for inserting the bolt for mounting the expansion valve are formed.

摘要： A valve body 30 of an expansion valve 10null is equipped with a first passage 32null formed by a cutting process through which a high-pressure refrigerant travels, and on the lower portion of the valve body 30 is formed a space 35a defining a valve chamber 35null from the bottom portion of the valve body 30 along the axial direction by a passage 33. The passage 33 defining the space 35a and the first passage 32null are formed so as to interfere with each other, and at the interference area is formed a throttle portion 323. That is, the diameter of the first passage 32null is formed so that the cross-sectional area thereof is gradually reduced toward the direction of the valve chamber 35, and a throttle portion 323 is formed to the area of the first passage 32null interfering with the passage 33 defining the valve chamber 35null. The throttle portion 323 is formed to have a cross-sectional area corresponding to a diameter of approximately 3 mm. By such structure, the bubbles mixed inside the liquid-phase refrigerant is fined, and refrigerant passage noise is reduced.
