FIELD: mining.
SUBSTANCE: group of inventions relates to mining and can be used for control of downhole device. Apparatus for controlling a downhole device in a well has a body with a control slot and pin movable in slot. Slot has a first inactive loop in which pin can cycle between different idling configurations, and a second active loop in which pin can move between different configurations which correspond to active and inactive configurations of downhole device. Pin can be switched between first and second loops, and can cycle between different configurations within without switching between different loops. Slot can be provided on a piston, and axial movement of piston in bore can drive relative movement of pin and slot.
EFFECT: technical result consists in improvement of efficiency of controlling downhole device.
