摘要

The buffer device of internal pressure for rotating electrical machine capable of operating in explosive atmospheres and electric machine traversing. The present invention includes a pressure dampening device (1, 10, 100) for an electric machine of the type which has a giant envelope which defines a cavity with a set rotor stator.The dampening device of pressure (1,10, 100) is disposed within the cavity and comprises a shield with a plurality of openings to secrete a flame front which propagates from an ignition point formed by a combustion process originated in the cavity.Thus, the device (1,10100) secretes a flame front, avoiding that compress gases which has not passed through the combustion process. With the use of the device (1, 10, 100) of the present invention is a clear reduction of pressure in the inner cavity of the machine power ICA traversing.In a first implementation, the device (1) comprises pressure buffer of a circular ring (2) with a plurality of openings (3) arranged on the wall of the ring (2). In a second implementation, the device (10) comprises a wall (20) in the form of a polyhedron defined by a finite plurality of sides of the wall (20a), with a plurality of openings (30) arranged on either side of the wall.In a third implementation, the device comprises a pressure attenuator disk (100) with a flat wall (200), and a sloping wall (201) which protrudes from the flat wall (200), the sloping wall (201) having a plurality of openings (300).
