Compression device of a supply of ink to the soiling of documents in an enclosure securisee

摘要

The present invention relates to a compression device (1) of a reservoir, particularly used in devices of the set-off for the projection of the product or of liquid in the documents, comprising a frame of base (13) defined in a plane "e ", a movable element (15), defining in its initial position a bearing plane" p " on the tank parallel to the plane "e ", and of a motor element (17), the activation of the motor element (17), causing the displacement of the movable element (15); said device is noteworthy in that the motor element (17) is composed of pyrodynamiques means making it possible, when the motor element (17) is activated, the translation of the plane" p " of the moving element (15) along a rectilinear direction perpendicular to the plane "e ", ensuring a homogeneous and uniform distribution of the force of compression of the moving element (15) on the reservoir, and the dynamic displacement of said moving element (15) to its final position, parallel to the initial position, where the reservoir is emptied of its contents.
