Abstract (en)
[origin: EP0269882A2] The piston compressor driven by an electric motor has four cylinders (1, 2, 3, 4) connected in series on the gas side and each having a piston (7, 12, 28, 32) guided therein. Two pistons (7, 12 and 28, 32) are opposed to one another on a common axis in each case, with their piston rods (8, 13, 29) connected to one another via a yoke (9 or 30) to form a pair. The axes (5, 6) of the two pairs of pistons thus formed intersect one another and each pair of pistons is positioned in an essentially horizontal plane. Engaging in the two yokes (9, 30) of the pairs of pistons by way of a slider (11, 31) is a common crankpin (10) acting as the driving element. The gas to be compressed is fed to that side of the piston remote from the compression chamber (15) of the first compression stage via at least one intake valve (18) located in the piston (7) and the drive motor for the compressor is located beneath the horizontal planes of the two pairs of pistons (7, 12; 28, 32). <IMAGE>
