Abstract
The invention relates to an auxiliary lubrication unit for lubricant introduction devices. The unit comprises a base body (), in whose longitudinal bore () a control piston () is displaced axially by a spring () towards a seal () and also comprises lateral connections () of a chamber () that is delimited by the control piston () in the longitudinal bore (). The connections run from a lubricant pump and to an installation that is to be supplied with lubricant and allowing lubricant to be transported, in the sealing position of the control piston (), through the chamber () from the lubricant pump to the installation. If the pump fails, the control piston () can be displaced by remains of auxiliary lubricant from its sealing position, in opposition to the action of the spring (), into a position in which the connection () to the installation is open and the connection () to the lubricant pump is closed, enabling the installation to the filled with the auxiliary lubricant.
