ABSTRACT:
An expansion valve includes a valve body, an adjusting mechanism for adjusting a flow rate of a refrigerant supplied to an evaporator and a control mechanism for controlling said adjusting mechanism in accordance with a temperature of the refrigerant supplied to a compressor from the evaporator. The body has a first passage for introducing the refrigerant to the body, a second passage for supplying the refrigerant from the first passage to the evaporator and a third passage for transferring the refrigerant to the compressor from the evaporator. The adjusting mechanism has a restriction for connecting the first passage with the second passage and a valve member for adjusting a degree of the restriction. The control mechanism has a heat sensitive chamber filled with the gas in a sealing manner and a diaphragm movable in accordance with pressure in the sensitive chamber. A transmitting member transmits the temperature of the refrigerant flowing in the third passage to the gas in the sensitive chamber and the movement of the diaphragm to the valve member. The body is made of a synthetic resin. A metal member is disposed in the body between the first passage and the second passage. The metal member has the restriction and a valve seat for contacting the valve member.
