A hermetic compressor with internal thermal insulation, comprising: a compression cylinder having one end closed by a valve plate provided with a discharge orifice and having a front face against which is mounted a cylinder cover internally defining a discharge chamber; and a spacing duct having one inlet end hermetically mounted to the front face of the valve plate and open to the discharge orifice and an outlet end hermetically mounted to the cylinder cover and open to the interior of the discharge chamber, said spacing duct defining a hermetic fluid communication between the interior of the compression cylinder and the discharge chamber maintaining the cylinder cover spaced from the valve plate and defining, with the latter, an annular plenum around said spacing duct.

A clamp for mounting a tubular connector in a refrigeration circuit includes two semi-annular portions having end sections with each of the end sections including surfaces which extend radially outwardly from the annular portions of the clamp and a lock for locking the ends of the semi-annular portions together around the end of the tubular connector with the radially extending end surfaces of the end sections in abutting engagement.

A piston-and-cylinder assembly, used in cooling sys terns that may include, for example, refrigerators, air-conditioning systems and the like. In order to solve the problems of volumetric loss (or of cooling capacity) of compressors in general, according to the present invention, one foresees configuring the cylinder () of the compression chamber in such a manner that the friction will be as low as possible in the phase in which the gas being compresses still does not exert a significant force onto the piston () top and will only have a significant effect during the phase in which the gas to be compressed exerts a greater force onto the piston (), a moment when the volumetric loss impairs the efficiency of the compressor.
