Abstract: A drive for a lubrication pump for a centralized lubrication system of utility vehicles, including trailers, semi-trailers, special vehicles and the like. The lubrication pump is used for lubricants which are difficult to press and have a high penetration. The lubrication pump includes an agitator mounted in a lubricant container and an eccentrically driven delivery piston transporting the lubricant. The agitator and the eccentric member are mounted on a common drive shaft. The drive for the lubrication pump is a pneumatic drive and is controlled by an explosion-protected magnetic valve.

Abstract: A method and an apparatus for adjusting the lubricating time of a lubrication pump which is driven by a motor whose rate of rotation varies. The adjustment is carried out with a cycle time which includes the lubricating time and a non-lubricating time. The lubricating pump is used in the centralized lubrication of utility vehicles. The lubricants used are lubricants which are difficult to press and have a high penetration. The lubricating time is adjusted in dependence upon the number of rotations carried out by the pump.
