Abstract

A throttling device is equipped with a valve seat in which a valve port for connecting a primary chamber and a secondary chamber is formed, a needle valve, a needle section which is inserted into the valve port, a guide section for guiding a slide shaft of the needle valve, and a coil spring for biasing the needle valve in a valve-closing direction. The guide section and the coil spring are positioned on the primary chamber side. The coil spring is covered by a stopper section. A gap between the stopper section and a main body case functions as a main body path for delivering a refrigerant from the primary chamber to the valve port.
