    Abstract: An air conditioner and evaporator inlet header distributor therefor are provided. The air conditioner may include an evaporator inlet header distributor to distribute a refrigerant expanded in an expansion mechanism to a plurality of refrigerant flow paths of an evaporator. The evaporator inlet header distributor may include a distributor body, a refrigerant inlet pipe to guide refrigerant expanded in the expansion mechanism to an inside of the distributor body, a plurality of refrigerant outlet pipes to discharge the refrigerant from the distributor body into the plurality of refrigerant flow paths, and a separating plate to separate the inside of the distributor body into a header flow path connected with the plurality of refrigerant outlet pipes and a refrigerant dispersing flow path connected with the refrigerant inlet pipe to guide an upper portion and a lower portion of the header flow path by dispersing the refrigerant. Accordingly, two-phase refrigerant may be uniformly distributed to the plurality of refrigerant outlet pipes using a simple structure.

    Abstract: A valve piece urging member urges a valve piece toward a valve closing side, at which an opening degree of a restriction passage is reduced by the valve piece. An actuation member exerts a drive force against the valve piece in a direction of moving the valve piece toward a valve opening side, at which the opening degree of the restriction passage is increased by the valve piece. A vibration limiting member limits vibration of the valve piece in a direction, which intersects with the axial direction, by generating an urging force for urging the valve main body at a location between the valve main body and the valve piece. When the valve piece is moved beyond a predetermined displacement position toward the valve opening side, the valve piece releases the urging force of the vibration limiting member.

    Abstract: An expansion device unit (4) for a vapor compression system (1), and a vapor compression system (1) are disclosed. The expansion device unit (4) comprises an inlet opening (17) arranged to receive fluid medium, at least two outlet openings (18) arranged to deliver fluid medium, a main expanding section (6) adapted to expand fluid medium received via the inlet opening (17) before delivering the fluid medium to the outlet openings (18), and a distribution section (7) arranged to split the fluid flow received via the inlet opening (17) into at least two fluid flows to be delivered via the outlet openings (18). The main expanding section (6) and/or the distribution section (7) is/are arranged to cause pressures in fluid delivered via at least two of the outlet openings (18) to be distinct. The main expanding section (6) is operated on the basis of one or more parameters measured in the fluid flow delivered by one of the outlet openings (18). The distinct pressure levels allow distinct evaporating temperature in evaporator paths (5a, 5b, 5c) connected to the outlet openings (18). Thereby a large temperature difference between inlet temperature and outlet temperature of a secondary fluid flow across the evaporator (5) can be obtained, without requiring that the entire mass flow must be compressed from a low pressure level by the compressor (2). Thereby energy is conserved.

    Abstract: A decompression device includes an upstream throttle portion, a middle passage portion and a downstream throttle portion, which are arranged within a body portion. The upstream throttle portion is a variable throttle including an upstream throttle passage in which the refrigerant is decompressed and expanded, and a valve body having an open degree adjusting portion configured to adjust an open degree of the upstream throttle passage. The downstream throttle portion is a fixed throttle for decompressing and expanding refrigerant flowing from the middle passage portion. Furthermore, a refrigerant passage defined from the upstream throttle portion to the downstream throttle portion through the middle passage portion is provided in the body portion, and is bent at least at a bent portion in which the refrigerant flow is bent in the body portion.
