Interior pump sprockets no falciforme.

摘要

The invention relates to a pump INTERIOR ELEMENTS WITHOUT GEAR sickle-shaped, with a crown of toothing AND A pinion meshing with the crown. Pinion and Crown SUPPORTING pivotably on a housing having suction inlet ONE AND A pressure. CROWN INTRODUCES radial passages creating a conductive connection between the base of the tooth and the side surface of the crown. IN THE HEADS OF TOOTH CROWN (1.3) O PINION ANTICIPATED a profile (1.4) SLOT IN WHICH RESPECTIVELY INTRODUCES sealing element (4) that can slide HEAD OF TOOTH OPPOSITE PINION OR CROWN. The profile, VISTA SLOT IN A CUT perpendicular to the axis is free of connections. The sealing element is provided with a channel (4.1) ESTABLISHING A conductive connection between the base PROFILED SLOT (1.5) and the sealing surface (4.2) of the sealing element. The channel, viewed in the direction of rotation of Pinon, surrounded by the material of the sealing element. The sealing element (4) can move LIMITED way profiled groove (1.4) in the radial direction, forming a gap (5) between the outer surface of the sealing element AND INTERIOR SLOT textured surface, SO THE SLOT BASE PROFILED (1.5) IS IN UNION WITH CONDUCTING FACE PRESSURE.
