Abstract: A refrigerant pipe connected to a suction side of a compressor and a refrigerant pipe connected to a discharge side of the compressor are integrated into one body. A refrigerant pipe connected to an inlet side of a condenser and a refrigerant pipe connected to an outlet side of the condenser are integrated into one body. A refrigerant pipe connected to an inlet side of a decompressor and a refrigerant pipe connected to an outlet side of the temperature detecting portion are integrated into one body. In these piping structures, a double pipe structure and a double pipe joint structure are adopted in which an inner pipe for circulating high pressure fluid and an outer pipe for circulating low pressure fluid are formed separate from each other and the respective end portions of the pipes are joined to a joint member by plastically deforming the pipes.

Abstract: A pipe is received through a through hole of a connector. A bulged portion of the pipe is press fitted into a recess of the connector located at a first side of the connector and a retaining member is located at a second side of the connector.

Abstract: A structure for mounting a heavy article 27 to a carrier body 31 via an intermediate member 20, capable of temporarily fixing the heavy article during the mounting operation, wherein the intermediate member 20 is provided in a lower part thereof with a lower attachment portion 21 having holes 26 for fixing the heavy article 27 and in an upper part thereof with upper attachment portions 23 having engagement portions 25 for being temporarily fixed to the carrier body 31 and fixation portions 24 for being firmly fixed to the carrier body 31. To fix the intermediate member 20 to the heavy article 27, the lower attachment portion 21 of the former is sandwiched between a pair of elastic members 28 made of soft material, and fastened to the heavy article 27 by fastening members 30 through the holes 26, for allowing a slight vibration of the heavy article 27.

Abstract: In one instance, a pipe is received through a through hole of a connector. A bulged portion of the pipe is press fitted into a recess of the connector, and holding projections of the connector are bent against an outer peripheral surface of the pipe to hold the pipe. In another instance, a pipe is received through a through hole of a connector. A bulged portion of the pipe is press fitted into a first side recess of the connector, and a securing member is press fitted into a second side recess of the connector.

Abstract: A refrigerant pipe connected to the suction side of the compressor 1 and a refrigerant pipe connected to the discharge side of the compressor 1 are integrated into one body, a refrigerant pipe connected to the inlet side of the condenser 2 and a refrigerant pipe connected to the outlet side of the condenser 2 are integrated into one body, and a refrigerant pipe connected to the inlet side of the decompressor 3 and a refrigerant pipe connected to the outlet side of the temperature detecting portion are integrated into one body. In this piping structure, a double pipe structure and double pipe joint structure are adopted in which an inner pipe for circulating fluid of high pressure and an outer pipe for circulating fluid of low pressure are formed differently from each other and the respective end portions of the pipes are joined to a joint member by a plastically deforming means.
