Abstract
A system for automatically delivering lubricant to at least one bearing (16) has a lubricant pump (1) feeding lubricant under pressure through a supply line (3) to an injector (4). The injector, driven by the lubricant, sends a measured amount of lubricant down feed line (14) to bearing (16). A pressurizing valve (15) maintains injection pressure in the feed line (14) enabling any failure of supply to be detected as a pressure drop at pressure switch (2). Preferred features include the incorporation of a second pressurizing valve (12) at the injector end of the feed line (14), a blocked-line vent valve (13) to enable detection of a blocked or crushed feed line, and check valves (10) and (11). The injector (4) is preferably configured to produce a higher pressure at the outlet than the inlet, and various versions of this intensifying injector are described and claimed.
