Compression device and method

Abstract

The invention relates to a fluid compression device comprising a compression chamber housing a piston (5) movable between the first (3) and second (6) ends of the compression chamber, the device (1) comprising a regeneration circuit (7) connecting the first (3) and second (6) ends of the compression chamber and comprising a regenerator (17), the supply line (8) comprising a set of valve(s) (9), the device (1) comprising at least one compressed fluid discharge line (10) comprising an upstream end connected to the compression chamber and a downstream end intended to be connected to a compressed fluid receiver, the device comprising a bypass line (12) comprising an upstream end connected to the regeneration circuit (7) and a downstream end connected to a recovery device (13),The bypass line (12) is configured to remove a fraction of fluid during a regeneration phase in which the piston (5) is moved from the second (6) end to the first (3) end of the compression chamber.
