EXPANSION VALVE FOR AN AIR-CONDITIONER OF A VEHICLE

摘要

PURPOSE: An expansion valve for air conditioners of vehicles is provided to be miniaturized through reducing the whole volume with reducing a height. CONSTITUTION: An expansion valve for air conditioners of vehicles comprises a valve body and a bracket(200a). The valve body comprises a first port, a second port, a third port and a fourth port. Refrigerants flow in through a first port from a condenser. The second port formed in a first side supplies the refrigerants to an evaporator. The third port is formed separately from the second port and inflows the refrigerants from the evaporator. The fourth port is formed in a second side and discharges the refrigerants flowing through the third port. . The valve body comprises a throttling path and an inner flow path. The inner flow path is formed side by side with the throttling path and sends the refrigerants flowing into the first port to the throttling path. The bracket comprises a port insertion part(210), pipe insertion unit(220), and a guide passage. The port insertion part is inserted into the first port. The outer of the compressor is inserted into the pipe insertion unit. The guide passage connects the port insertion unit and the pipe insertion unit.
