Title:
MACHINE WITH ROTATING PISTONS
Document Type and Number:
WIPO Patent Application WO/2003/056182
Kind Code:
A1
Abstract:
The present invention raltes to a fluid compressing or pumping machine with rotating pistons, e.g. a compressor or a pump. It comprises a stator (3) and a combined rotating pistons (1). In the stator (3) there are an inner chamber (8), an inlet chamber (11) and an outlet chamber (12). Each piston structural unit (13) comprises a piston surface (14) and a bracket (15). Piston structural units (13) are hinged with each other through pins (2). A bearing (5) is mounted on each pin (2). The lines connecting each hinging holes define a parallelogram. Supporting tracks (6) are arranged on both sides of the inner chamber (8). Bearing (5) on the combined rotating piston (1) periodically move along the supporting tracks (6). The piston surface (14) of the combined rotating pistons (1) coprates with the curve of the chamber of the stator (3) to form several rooms.
