DEVICE FOR TAKING PRESSURIZED SAMPLES

摘要

This invention relates to a device for taking pressurized samples of gas, and/or liquids, and/or solids, such as gas hydrates, enabling sampling without requiring the sample (E) to be moved, in particular without suction, and without mixing the initial volume. It comprises a sampling enclosure (1) consisting of a liner (11) and a spindle (121) equipped at its ends with cylindrical stoppers (122, 123), and an actuator (2) comprising a cylinder (21) equipped with means of connecting (285 the interior of the cylinder with the exterior in order to move the actuator piston (22) between activated and deactivated positions, one of the elements amongst the liner and the spindle being capable of being assembled to the actuator cylinder, and the other element to the free end (231) of the piston rod (23), whereby at least one of the spindle stoppers is not inserted into the liner in the activated position of the piston, and the enclosure is in closed position in the deactivated position of the piston.
