Feeding lubricating device

摘要

A single line lubrication system has a reciprocating pump (2) driven by a motor driven linkage to pump lubricant from a reservoir (1) to the lubrication line (4), to at least one lubrication point or to a distribution manifold (5) for several lubrication points. The reciprocating drive linkage also drives a reciprocating valve which blocks the return line (22) in the pressure phase of the pump cycle and opens the return line in the return phase of the pump cycle. This provides a simple return to the reservoir of excess lubricant.
