<p>GEOTHERMAL WELL SAMPLER APPARATUS An elongated body member, a portion of which forms a chamber for retaining samples of the liquid and steam contents of a geothermal well. A fluid tight seal is formed between an O-ring and a parallel sealing face of a slidable shaft member. The pressure sealing force is adjustably controlled by a spring assembly. The spring assembly is adjusted so that the sealing force must be overcome before a sample is taken, When the sealing force exerted upon the seal is overcome, the sample chamber is placed in fluid communication with the geothermal borehole by a series of passages which include grooves or slots contained in the slidable shaft member, After sampling is complete the seal is reformed allowing the sampler to be retrieved to a surface location.</p> |
