Abstract:
1. A lubricating device for use in an apparatus for lubricating migrating lubrication sites, in which a lubricant discharge body of a lubricating head, which during the filling of lubricant from a feed pump into a dosing chamber cut off from the lubricant discharge channel is located in a forward standby position and, against the action of a reset force is rearwardly displaceable into a blocked and lubricant release position, in which, on the one hand, the connection between feed pump and dosing chamber is blocked by a reversing piston and, on the other hand, the dosing chamber is in fluidic connection with the lubricant discharge channel, and a predetermined volume of lubricant can be transported from the dosing chamber into the lubricant discharge channel, wherein the lubricant discharge body cooperates with a reversing piston such that the feed pump is fluidally connected with the dosing chamber of a dosing piston/cylinder configuration via an annular space of the reversing piston when the lubricant discharge body is located in a forward standby position, and that the dosing chamber is fluidally connected with the lubricant discharge channel via the annular space when the lubricant discharge body is located in a rearwardly displaced lubricant release position, in which the reversing piston blocks the fluidic connection between feed pump and dosing chamber, and that the lubricant quantity provided for the delivery is transportable by means of a dosing piston acted upon by the feed pump from the dosing chamber in the direction of the annular chamber.
