- 23 - ABSTRACT A fluid sampler is disclosed which operates so as to trap a liquid sample and then eject to. To achieve this, a piston (18) and sleeve (14) are displaced together downwardly to move a pair of port- holes (10, 11) in the piston out of register with a pair of ports (2, 3) in the sleeve wall to as to trap the liquid sample in an internal space in the piston interconnecting the two portholes (10, 11). In this position the sleeve (14) is restrained against further downward movement. On continuing downward advancement of the piston, the trapped liquid sample is ejected out of the internal space through a passageway (21) in the piston for analysis. The sampler is ideally suited for taking oil sample from a pipeline and can be designed for isokinetic sampling.
