Problems solved by technology

In addition, copper fittings are also used to connect the cone filter to the compressor valve, which exposes a complex manufacturing and assembly process and, therefore, is expensive
[0010] Therefore, it can be noted that the state of the art currently lacks such connecting pipes, which are joined by different materials to form a single part, thus allowing more economical manufacture and easy installation, no longer requiring the use of several separate elements to connect the They fit into the compressor or system piping

Embodiment Construction

[0023] The present invention will be further described according to the accompanying drawings.

[0024] figure 1 Shown is a connecting pipe 2, commonly used in the present case of the prior art, for connecting the casing 1 of the compressor to any pipe 3, which may be a process valve or an evaporating and / or A hermetic compressor is installed in the tubes of a condensing system, refrigerator or freezer. This is a single part typically made of a single material, usually copper, having one end connected to the compressor housing 1 and the other end connected to the system pipe 3 .

[0025] Usually, connecting the connecting pipe 2 to the system pipe 3 is done by figure 1 The brazing part 4 indicated in the mark is implemented.

[0026] The preferred embodiment proposed by the present invention sees in detail figure 2 , wherein the joint 2 is composed of two tubular parts 5 and 6, the first part 5 of the connecting pipe 2 is made of one material, and the second part 6 of the...

Abstract

The present invention relates to a connecting tube (2) for hermetic compressors, which is responsible for connecting the housing (1) of a hermetic compressor to the tube (3) which may be the process valve tube or evaporation, condensation system which comprises at least two portions composed of materials that are different from each other, which are associated by means of a suitable joining process preferably welding, soldering or mechanical fastening. In the preferred embodiment of the invention, the connecting tube (2) comprises a first portion (5) comprising a first material and a second portion (6) composed of a second material, wherein the second portion (6) of the connecting tube (2) can join the first portion of the connecting tube (5) and the system tube (3).

Description

technical field [0001] The present invention relates to a closed joint, preferably made in the form of a tube, which was developed primarily to reduce manufacturing costs by using several materials in its construction. Background technique [0002] Widely used in the field of refrigeration, especially hermetic compressors used in cooling refrigerators, this equipment needs to ensure that the leakage of working gas is minimal to provide longer equipment life, reduce maintenance intervals and improve thermal efficiency . [0003] The key point for maintaining the airtightness of the compressor is the connection of the compressor to the evaporating and condensing system, which is usually implemented by connecting pipes, which are fixed by welding, soldering or mechanical fastening. The same happens to the connections of the process valve pipes used to inject oil or coolant during the fitting of the compressor into the system or in case the system requires maintenance. [0004...
