摘要： A double pipe forms an inner flow path, through which a low-pressure side refrigerant flows, inside an inner pipe, and forms an inner-outer flow path, through which a high-pressure side refrigerant flows, between the outer pipe and the inner pipe. It comprises an expansion valve side connector and a counter-expansion valve side connector which are interposed between distal ends of the outer pipe and the inner pipe and members to be connected. An outer diameter of the outer pipe is 30 millimeters or less. A ratio of a difference between an inner diameter of the outer pipe and an outer diameter of the inner pipe with respect to the inner diameter of the outer pipe is 25% or less. A sealing member is provided to prevent a refrigerant leakage. The plurality of members are mechanically fixed.

摘要： A refrigeration cycle device includes a flow channel coupling member which constitutes at least one of a branching portion and a joining portion of a third refrigerant passage and a branching portion and a joining portion of a bypass passage. One of three refrigerant ports of the flow channel coupling member is directly connected to one of two refrigerant ports of a first switching device or a second switching device, and a sealing mechanism preventing a refrigerant leakage is provided in a connecting portion between the refrigerant port of the flow channel coupling member and the refrigerant port of the first switching device or the second switching device. The flow channel coupling member is fixed to one of the switching devices at a position different from a position of the sealing mechanism.

摘要： A piping includes: a hose made of an elastic material; a pipe made of metal, the pipe having an insertion part inserted inside of the hose; and a sleeve arranged on an outer side of the insertion part and the hose in a radial direction. The insertion part has an uneven surface around an outer circumference side of the insertion part, and the uneven surface has an annular groove and an annular projection. The groove has a groove slope that narrows the pipe toward a tip end of the insertion part, and a groove bottom that extends from an insertion-tip-side end of the groove slope to the projection with a constant outer diameter. The sleeve has a small diameter part located on an outer side of the uneven surface in the radial direction to press the hose against the uneven surface.

摘要： An aluminum alloy-made connector capable of preventing corrosion in a desired region even when being caulking-jointed to a piping member, a piping member for connecting a heat exchanger including the connector, and methods for manufacturing these are provided. The aluminum alloy-made connector is configured by an aluminum alloy extrusion material containing 0.2% to 0.8% (mass %, the same shall apply hereinafter) of Si, 0.45% to 0.9% of Mg, xZn% of Zn, and 0.001% to 0.2% of Ti, with the balance being Al and inevitable impurities. Herein, xZn satisfies {(X2+2r2)1/2+34}/38≤xZn≤2.0 (when the piping member is made of an Al—Mg—Si based aluminum alloy) or {(X2+2r2)1/2+16}/24≤xZn≤2.0 (when the piping member is made of an Al—Mn based aluminum alloy). Provided that, in the formula, X is the distance (mm) from the caulking jointed connector to the length-direction end portion of the region requiring corrosion prevention, and r is the radius (mm) corresponding to the external diameter of the piping member.

摘要： A double-wall pipe includes an outer pipe, and an inner pipe disposed inside the outer pipe. An outer wall of the inner pipe has thereon a ridge portion, which defines a groove portion extending in a longitudinal direction of the inner pipe. The outer pipe and the inner pipe are bent to have a straight portion extending straightly, and a bend portion bent from the straight portion. In the straight portion, the outer pipe has an inside diameter that is larger than an outside diameter of an imaginary cylinder defined by an outer surface of the ridge portion of the inner pipe. Furthermore, the ridge portion of the inner pipe contacts an inside surface of the outer pipe to be radially squeezed and held by the outer pipe, in the bend portion. The double-wall pipe can be suitably used for a refrigerant cycle device.
