The sleeve (sometimes name the cartridge) has a cavity of cooling - a shirt or, in case of air cooling - cooling edges that provides an intensive heat-conducting path from an internal working surface for maintenance of necessary thermal balance of details TSPG.

The sleeve, takes among heat-stressed details of the engine a special place, both on carried out functions, and under requirements showed to it. Maintenance only one durability of the cartridge, despite of all importance of this requirement, is not enough for long and reliable work of the engine.
