<P>PROBLEM TO BE SOLVED: To provide an expansion valve improved in its mounting performance by arranging channels of the expansion valve at a right angle, and forming a guide part in the channel for guiding the flow of the working fluid, and reducing the resistance and noise of the channel. <P>SOLUTION: This expansion valve is composed of a main body 110 comprising one or more channels 111, 114 wherein central lines of inflow ports 112, 115 and central lines of outflow ports 113, 116 are positioned approximately at a right angle, and having the guide part 114a for guiding the flow of the working fluid, on an intersection point of the inflow port 115 and the outflow port 116, a head part 120 mounted on the main body 110 and axially reciprocating a rod 130 by the expansion and contraction by the change of a temperature of the working fluid discharged from an outlet of an evaporator 40 and flowing in the channel 114, and an opening and closing means 140 for adjusting a flow rate in the channel 111 in interlocking with the movement of the rod 130. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
