Abstract
The invention relates to a feeding lubricating device comprising a lubricant reservoir (1), a lubricant pump (2) which is driven by a driving motor (16) and is provided with at least one pump element (3) for conveying lubricant to at least one lubrication point, especially at least one feeding distributor (5), via a lubricant conduit (4), a driving member such as a drive shaft, and optional means that are fitted with an eccentric attachment for generating at least one pump stroke of the at least one pump element (3). A pressure relief unit (8) which can also be actuated via the driving member blocks a backflow pipe (4) located between the lubricant conduit (4) and the lubricant reservoir (1) in a pressure phase while unblocking the same in a subsequent relief phase.
