A fluid pump for lubricants which comprises a drive shaft (3) mounted in a stationary housing (2) and driving an axially connected eccentric control shaft (6). The control shaft has a rotatable collar (8) mounted on it which forms a "cylinder ring" and has a radially inwardly extending bore which cooperates with a piston (10) pivotally mounted on the housing by means of a pin (12) parallel to the drive shaft (3). The engagement of the piston with the bore prevents the cylinder ring from rotating with the control shaft so that rotation of the drive shaft, and therefore the control shaft causes the cylinder ring to reciprocate relative to the piston. <IMAGE> |
