Abstract
A throttle device to decompress a refrigerant and to deliver the refrigerant to an evaporator, may have an opening level of a needle valve controlled following a condensation pressure. Inside a case including a primary chamber connected to the condenser and a secondary chamber connected to the evaporator, a valve seat formed with a port and a guide integral to the valve seat are provided. A spring to energize the needle valve toward the port side is provided inside the guide. The guide guides the needle valve along a line allowing an opening level of the port to be variable. A space between the guide and the case forms a channel to deliver the refrigerant from the port to the secondary chamber. A rear space of the needle valve within the guide forms an intermediate chamber. An intermediate channel introduces the refrigerant from the port into the intermediate chamber.
