摘要： In a refrigerant cycle with an ejector, there is provided with a bypass passage through which a part of high-pressure refrigerant from a radiator flows into a low-pressure refrigerant passage between an evaporator and a suction port of the ejector while bypassing a nozzle of the ejector. Further, a control valve is disposed to open the bypass passage so that refrigerant flows through the bypass passage when the pressure of the high-pressure refrigerant becomes in a predetermined condition. Accordingly, it can prevent the pressure of the high-pressure refrigerant from being excessively increased due to increase of a refrigerant flow amount. Therefore, the refrigerant cycle operates stably.

摘要： An expansion device for the heat pump applications consists of a flow resistance device that has a different resistance to refrigerant flow depending on the flow direction through this device. The flow resistance device has no moving parts so that it avoids the damage, wear and contamination problems of the moveable piston in the prior art. The flow resistance device is a fixed obstruction about which the fluid must flow when traveling through the expansion device.

摘要： In an expansion valve the pressure vessel of which is constituted by a reduced number of parts and which does not require seal members a valve unit is surrounded by first and second half shells which in turn are surrounded by a pressure vessel formed as a one-piece body by molding resin by an insert molding process. Since the resin constituting the resin molded one-piece pressure vessel simultaneously form internal sealing member structures no additional seal members are required to be positioned and mounted. The first and second half shells are shaped such that the necessary refrigerant passages for the valve unit are defined in communication with connection holes of the pressure vessel.

摘要： An electronic variable orifice tube suitable for use as an expansion valve in a refrigeration system providing two flow rates in response to electronic control signals comprises a bodytube, a restrictor mounted within the bodytube and defining a first flowpath. A plunger is translatably positioned within the bodytube in proximity to the restrictor and defines a second and a third flowpath. A valve actuator is functionally coupled to the plunger to translate the plunger within the bodytube to transition between the two flow rates. A high flowpath is formed through the bodytube by the first, second, and third flowpaths, and a low flowpath is formed through the bodytube by the first and the second flowpaths to the exclusion of the third flowpath. A solenoid may be used as the valve actuator and a spring may be employed to return the plunger to its quiescent state when the solenoid is not energized.
