摘要： In an expansion valve for controlling the flow rate of a refrigerant supplied to an evaporator of a refrigerating system, a temperature-sensing chamber is provided to sense the temperature of the refrigerant returning from said evaporator and to actuate a valve mechanism in order to regulate the flow of refrigerant supplied to said evaporator. An adsorption means provided inside the temperature-sensing chamber to adsorb a liquefied part of a gas charge within said chamber in order to hold said liquefied part away from warm wall parts inside said chamber. In addition, or as an alternative, said temperature-sensing chamber is separated from a return passage of said refrigerant by thermal-transfer-delay means for delaying the thermal transfer of a temperature change from the refrigerant to a sealed charge within said temperature-sensing chamber. Said thermal-transfer-delay means can be made as a flow restrictor for supressing an excessive flow between said chamber and said return passage of the refrigerant.

摘要： An expansion valve (10) for controlling the flow rate of refrigerant supplied to an evaporator (1) of a refrigerating system comprises a temperature-sensing chamber (30) entirely provided within the housing (11) of said expansion valve in a low pressure passage (12) thereof. Said passage (13) is connected to the outlet of said evaporator (1) and the inlet of a compressor (2), for converting a temperature change into a pressure change in order to actuate a valve mechanism (20) in response to a rise and lowering in pressure of said temperature-sensing chamber to open and close a passage (13) for adiabatic expansion of the refrigerant. Said temperature-sensing chamber (30) contains a sealed gas charge and an adsorbent material (35) for adsorbing and releasing said gaseous medium in accordance with temperature changes sensed.
