Abstract

An improved lubrication arrangement for a piston member (2) arranged to be reciprocatingly movable in a cylinder element (1) of an injection pump for fuel or the like pressure medium, wherein lubricant is supplied under pressure into a lubrication groove (5) arranged in the cylinder element (1) and encircling the piston member (2). The flow-through of the lubricant is effected by providing the cylinder element (1) with at least one channel (6) extending in the longitudinal direction of the cylinder element, said channel (6) being connected with said lubrication groove (5) for leading lubricant continuously into another position on the mantle surface of the piston member (2) at a distance from said lubrication groove (5) further to be recovered and for possible recirculation. <IMAGE>
