摘 要：
- in order to open the arms (4) for
anchoring to the wall of a well (2) of a tool of the well (1), use is made of an elastic force which is constituted by a volume of gas compressed in a chamber (7b) of a cavity (7) inside the body of the tool, acting on a piston (8). In order to close them, it is used for feeding a hydraulic force opposing generated by a pump (13) driven by an electric motor (14), which brings the piston (8) in the withdrawn position. The piston (8) is hydraulically connected with the cylinders of actuators (5, 6) acting on the arm (4). It is possible to generate an elastic force sufficient in a very small volume, and easily modify its characteristics, by acting on the injection pressure of the gas and / or the size of the dead volume in the retracted position of the piston (8). < br / > -
application, for example, the coupling of probes of the well which can be used in seismic prospection, for example.
