Abstract
A lubricator comprises a container of variable volume holding a lubricant and having an opening for dispensing the lubricant. An electromechanical or electrochemical actuator operated by a control circuit makes it possible to reduce the volume of the container. An electrical circuit for displaying the state of the lubricator comprising a light source can emit at least one alarm light signal. A lid affixed to the container in a removable manner constitutes a housing for the electrical signal display circuit and defines a reference axis of the lubricator. A light diffuser guides the light emitted by the light source towards numerous light outlets distributed along the circumference of the lid in a manner that at least one of the light outlets is visible regardless of the position of an observer facing the lubricator and is located on a circle of observation centered on the reference axis of the lubricator.
