Abstract

A pump for ejecting a fine spray of low viscosity lubricant has a control piston portion (3) carried by a spindle which carries at the other end a stepped portion (5, 10) acting as a differential high pressure piston in a high pressure chamber in an intermediate housing section (8). The diferential portion carries a ball valve (11) controlling a through channel communicating with side outlets through the spindle between the two piston portions, and supplying the high pressure chamber. The whole system is connected wit h a set of non return valves, and the control piston (3) carries a permanent magnet (6) which operates with a proximity switch (7) controlling the electronica injection system.
