摘要

Improvements in air compressor applied in the brake system of railway locomotives and their wagons, which more particularly, was developed a compressor (1) powered by compressed air, which dispenses with the use of oil, which employs the technique The labyrinth, i.e., the plunger or pistu00e0o (3) don 't atrita with the walls of the cylinder (2),Dispensing with any type of lubrificau00e7u00e2o in the contact area with the air to be produced. This solution allows considerable savings in the cost of maintaining the brake system, since it dispenses with the use of oil, thereby eliminating the various disadvantages cited in the technique currently used.
