Multicylinder compressors

In the first centuries of development, compressors to increase capacity have done more with the cylinder bores up to 375 mm, running at speeds up to 400 rpm Resulting component parts were heavy and bulky. To take advantage of larger-scale production methods and ensure the interchangeability of parts, modern compressors, as a rule, multicylinder, with apertures in the size not more than 175 mm at higher shaft speeds. Machines of four, six and eight cylinders are common. They are organized in multibank configuration with two, three or four rods on one throw crankshaft to give a short, hard machine (see Fig. 4.4).

This construction gives a large number of the common parts - pistons, connecting rods, bulk and liners valves - through a series of compressors, and such parts can be replaced in case of wear or damage, not removing the compressor body since its installation.

Compressors for small systems, it will be easier, two, three or four cylinder (see Fig. 4.5).
