Abstract

The invention relates to a device for compressing a fluid, said device having a compression chamber accommodating a piston that is able to move in translation between the first and second ends of the compression chamber, the device comprising a regeneration circuit connecting the first and second ends of the compression chamber and having a regenerator, the supply pipe comprising a set of one or more valves, the device comprising at least one pipe for discharging the compressed fluid, said discharge pipe comprising an upstream end connected to the compression chamber and a downstream end intended to be connected to a receiver of the compressed fluid, wherein the regeneration circuit comprises, between the regenerator and the first end of the compression chamber, a heat exchanger that is configured to ensure an exchange of heat between the flow of fluid that has passed through the regenerator and a cold source.
