Detection device and lubricant distributor

A device for detecting a movement of a piston of a lubricant distributor, the device comprising:

• a movable actuator including a cylindrical permanent magnet,
• a movable indicator including an annular permanent magnet axially spaced from the movable actuator, and
• a movable cap that covers the indicator and is transparent in a region of the indicator,
• wherein the actuator is configured to be moved axially from an initial actuator position to an end actuator position by a movement of the piston,
• wherein the actuator and the indicator are configured and disposed such that a magnetic force prevails between them such that the indicator is moved axially from an initial indicator position to an end indicator position by the movement of the actuator from the initial actuator position toward the end actuator position, and
• wherein the movable cap includes an internal shoulder configured to contact the indicator and move the indicator from the end indicator position to the initial indicator position when the movable cap moves axially toward the movable actuator.

A device for detecting a movement of a piston of a lubricant distributor, the device comprising:

• a first housing having an internal bore and an outer guide surface,
• a second housing having an internal bore and an outer guide surface, the outer guide surface of the first housing extending into the internal bore of the second housing,
• an actuator comprising a first magnet element slidably mounted in the internal bore of the first housing, and
• a movable indicator including a second magnet element slidably mounted on the guide surface of the second housing,
• wherein the actuator is configured to be moved from an initial actuator position to an end actuator position by a movement of the piston from a first position to a second position, and
• wherein the actuator and the indicator are configured and disposed such that a magnetic force prevails between them such that the indicator is moved from an initial indicator position to an end indicator position by the movement of the actuator from the initial actuator position toward the end actuator position.
