Abstract
A device for taking samples of a gaseous fluid from a well at a given depth. The device includes a control portion having a probe which may be removably assembled to one end of a bottle portion. The probe includes an inner space communicating at one end with the outside through a passage-way for the inflow of the fluid within this space into the sampler and at another end through an inner channel with the sample receiving chamber in the bottle. A channel closure valve is mounted in the probe and provided with an actuator remote-controlled from the surface. A remote-controlled motor with a rotary output shaft extends in parallel relation to the axis of the device. A device for transforming the rotary motion of the motor shaft into an axial motion of a rod displaceable in the direction of the axis of the device is provided. A sample-taking valve, comprising a movable element for opening and closing the valve, is mounted in axially displaceable relationship on this rod.
