Abstract

Claims7
Automatic sampling device for atmospheric probes which enables a sampling program to be varied within wide limits, comprising a distributor having a full-length bore and pivotably mounted in a distributor housing having apertures on a hollow spindle in such a manner that the mouth of the bore during rotation passes across at least one of said apertures whereby the hollow spindle is connected on the one side to the bore and on the other to the pressure side of an air pump drawing in air from its surroundings and the distributor is driven by a shaft whose rotation controls the beginning, sequence and duration of the probes taken as a function of the local distribution of apertures on the distributor housing.
