る可逆式比−側型膨張弁。Primary and secondary ports 1. and a valve body having a valve seat therebetween, a pressure equalizing chamber having a pressure equalizing hole that faces and communicates with the secondary port with the valve seat positioned in the middle; A valve body is provided at the secondary port through a partition wall, and a valve body is biased against the valve seat by a spring, and a connecting rod connecting the plunger of an electromagnetic mechanism attached to the valve body and the valve body is connected to the valve body. A fine gap is provided in the insertion hole of the partition so that the connecting rod can move freely, and a step portion located at the next port is formed with respect to the connecting rod, and a small diameter connecting portion is provided through the step portion. A reversible valve connected to the valve element through the valve seat by a connecting part, with the stepped part serving as a pressure receiving part for the primary side pressure, the diameter of which is the same as that of the valve seat, and a spring opposing the spring in the electromagnetic mechanism. Formula ratio - side type expansion valve.
