AIR COOLED PISTON COMPRESSOR WITH SPECIAL COOLING AIR SUPPLY Russian patent published in 2015 - IPC F04B39/06 

FIELD: machine building.

SUBSTANCE: invention relates to the air cooled piston compressor for vehicles. Blower (2) has several cylinders (1a, 1b), is driven by the engine (3) and has fan (4) to produce cooling air flow. The fan (4) is located on the intermediate shaft (5) between the engine (3) and blower (2), suctions the cooling air form environment and transports it to the downstream channel (6) for the cooling air. The channel (6) for cooling air, at least partially enclosing the cylinders (1a, 1b), is made such that all installed in row cylinders (1a, 1b) can be uniformly streamlined by the cooling air. The cross-sections of the channel (6) for the cooling air are formed such that the cylinder (1b) the most close to the fan (4) by means the cross-section throttling is subjected to reduced cooling air supply. At that, at least another cylinder (1a), that is most far from the fan (4) is essentially supplied with the same cooling air, as the nearest cylinder (1b).

EFFECT: improved design.
