Document Type and Number:
WIPO Patent Application WO/2015/163003
Kind Code:
A1
Abstract:
A throttle device (10) for decompressing a coolant cooled by a condenser in a refrigeration cycle, and delivering said coolant to an evaporator, wherein it is possible to accurately set a minimum gap between a needle valve (4) and a valve port (21). The interior of a cylindrical body case (1) which configures a primary chamber (11) connected to the condenser and a secondary chamber (12) connected to the evaporator is provided with a valve seat member (2) in which the valve port (21) is formed, and a cylindrical guide member (3) which is integral with the valve seat member (2). The interior of the guide member (3) is provided with a coil spring (6) for biasing the needle valve (4) to the valve-port (21) side. A needle section (41) of the needle valve (4) projects from the valve port (21) toward the primary-chamber (11) side. A tip end section (41a) of the needle section (41) contacts a stopper member, and as a result, the position of the tip end section (41a) is set. The position of the stopper member (7) in the axial line (L) direction is adjusted by the amount of screwing relative to the valve seat member (2).
