Abstract

The separator serves to mechanically separate an actuator and an operating mechanism, such as a choke, a valve, a blow-out preventer or the like, which is displaceable by said actuator, for use especially in the field of oil or natural gas production. The separator is adapted to be arranged between the actuator and the operating mechanism and comprises at least a first component associated with the actuator and a second component associated with the operating mechanism. These first and second components are displaceable relative to one another by means of at least one application part, which is connected to the first or second component, between an engagement position and a release position. The application part is adapted to be brought into releasable engagement with a displacement part which is suitable for handling by a user. This allows the actuator and the operating mechanism to be easily separated by the respective separator, without said separator leading to any structural modifications or enlargements of the actuator and/or operating mechanism. In addition, the separator is easily operable especially by an external user, and a predetermined displacement of the operating mec…
