摘要： The invention relates to an arrangement in connection with a lubricant dispenser comprising a frame, which frame contains a metering cylinder (2) and a metering piston (1) moving therein as well as means for conducting lubricant alternately to each side of the metering piston (1), the means for conducting lubricant comprising a spindle (4) positioned in the cylinder (3) and provided with passages (5) remaining open during pressurization, the spindle (4) being arranged to move in the cylinder (3) so as to permit flow of lubricant in consequence of a movement of the spindle alternately either via a control valve to one side or the other of the metering piston (1) or directly to one side or the other of the metering piston (1), depending on dispenser. To improve selection of material, the spindle (4) is arranged to move only by rotating around its longitudinal symmetry axis. The rotary movement of the spindle (4) is arranged to be provided by means of a separate turning part (7) moving back and forth and rotating influenced by lubricant pressure and spring force.
