ABSTRACT:
The present invention concerns a device for extracting a sample of fluid from a hydraulic circuit having an extraction take-off, for detection of impurities.
The device comprises in particular a body (10, 12) provided with a ferrule (14), capable of fitting on the take-off; a perforator (22) fixed on the ferrule (14) and provided with at least one orifice capable of distributing the fluid into the body; a carrier (26) capable of receiving a container (32) provided with a perforatable capsule (36) and a filtering membrane (40), the carrier being displaceable from one to the other of two positions, comprising an extraction position where the capsule (36) is perforated by the perforator (22) and where the fluid penetrates into the container (32), and a non-extraction position where the capsule (36) is not perforated by the perforator (22), and where the fluid runs out outside the container (32).
