Patent number: 6006544Abstract: A refrigeration cycle that controls the deposit of foreign matter at inlet or outlet of a capillary tube, which forms an expansion device in the refrigeration, regardless of changeover from a cooling operation to a heating operation. In particular, in a refrigeration cycle using an alternative refrigerant, a junction is provided for joining an end of a capillary tube forming an expansion device to the piping through which the refrigerant flows. The junction has a slope defined by the inside diameter thereof, which gradually decreases from the side of the junction that joins the piping to the side of the junction that joined the capillary tube. An end portion of the capillary tube projects into the junction at the piping side. The projecting end of the capillary tube is opened obliquely to the axial line of the capillary tube. A hole is formed in the peripheral wall of the projecting end of the capillary tube.Type: GrantFiled: July 27, 1998Date of Patent: December 28, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yukio Watanabe, Hisao Wakabayashi, Hironao Numoto, Shinji Watanabe, Akira Fujitaka, Kanji Haneda, Yoshinori Kobayashi, Yuichi Yakumaru, Narito Yamaguchi
