Abstract

The dosing pump has two pistons (17,18) which installed inside a cylinder bore (12), sliding against the inside wall in a sealed manner. An alternating drive acts on the first piston, and a first stop (50) is reached by the second piston during its subsequent rearwards movement when approaching the first piston, and contacts an adjustable second stop (44) which sits on a threaded sleeve (32) which is adjustable by rotation by means of a thread (31,39) along the cylinder bore relative to the pump housing.
