Abstract (en)
[origin: EP1154076A1] The soil sampler has a plug tube with chamber to accommodate a soil sample, which is defined in radial direction by a wall. The chamber is open in distal direction to receive a sample, and is closed by a transverse wall in proximal direction. The chamber has fluid channels, and a remote-control valve to close these. A free diabolo-shaped plug or piston is fitted tightly into the chamber and moves between transverse wall and distal tube area, to define a sealed fluid chamber.
