| 摘要 | The invention relates to a means for generating electric energy in a borehole during drilling thereof, which means comprises a housing (30) having connector means (33, 34) at the ends thereof for inserting the housing (30) in a drill string. The housing (30) includes a conduit system (130) for passing fluid through the housing (30) a valve (111, 131) located in the conduit system (30) and an electric generator (110). The electric generator (110) consists of a stator (114) and an anchor (112). The stator (114) is mounted immovably in the housing (30) and the anchor (112) is mounted such that it can move in a reciprocating mode relative to the stator (114) by the action of changes in the fluid flow through the conduit system (130) caused by the operation of the valve (111, 131). | ||||||
