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.

Vapour-compression type refrigerating machine and double pipe structure and double pipe joint structure preferably used therefor

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.

Pipe joint structure

A structure for mounting a heavy articleto a carrier bodyvia an intermediate membercapable of temporarily fixing the heavy article during the mounting operation, wherein the intermediate memberis provided in a lower part thereof with a lower attachment portionhaving holesfor fixing the heavy articleand in an upper part thereof with upper attachment portionshaving engagement portionsfor being temporarily fixed to the carrier bodyand fixation portionsfor being firmly fixed to the carrier bodyTo fix the intermediate memberto the heavy articlethe lower attachment portionof the former is sandwiched between a pair of elastic membersmade of soft material, and fastened to the heavy articleby fastening membersthrough the holesfor allowing a slight vibration of the heavy article
