Abstract
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.
Claims10
An expansion valve comprising a valve body, a valve means for adjusting the flow rate of a refrigerant to be transmitted to an evaporator, and a power element portion for driving said valve means according to the temperature of said refrigerant transmitted from said evaporator to a compressor, wherein said valve body comprises protruding portions formed integrally to the side surface of said valve body.
An expansion valve comprising a valve body, a valve means for adjusting the flow rate of a refrigerant traveling through a first passage formed inside said valve body from a condenser toward an evaporator, and a power element portion for driving said valve means according to the temperature of the refrigerant traveling through a second passage formed inside said valve body from said evaporator toward a compressor, wherein said expansion valve includes protruding portions formed integrally to the side surface of said valve body corresponding to penetrating holes formed to said valve body for mounting said expansion valve.
An expansion valve comprising a prismatic valve body, a valve means for adjusting the flow rate of a refrigerant to be transmitted to an evaporator, and a power element portion for driving said valve means according to the temperature of the refrigerant transmitted from said evaporator to a compressor, wherein said valve body comprises a prismatic projection formed integrally to the side surface of said valve body.
