![]() The piston of pumping is consisted 
            by the stem E. This stem is in reciprocating motion by its off-centeri 
            D on the rtoothed 
            centered in C.  The pawl B fixed on the base of the oiler imposes the direction of rotation dela toothed wheel pawl A gives the rotary movement to the toothed wheel because it is integrated into the stem of pumping. This stem is moving of comings and goings because a play of rod connects it to the rotary axis to lubricate. The output flowcontrol is obtained by the adjustment of the value S of exentrage and arm of lever. A ball valve is imperative so that the pump is effective  |
