Abstract
A dual dispenser having two pumps and an outlet channel that is fed with the fluids coming from both pumps. The two pumps include respective actuator rods that are movable axially over strokes of different lengths, namely a first actuator rod having a long stroke, and a second actuator rod having a short stroke. The common dispenser head includes a pivot member that forms two bearing elements that are constrained to move together, so as to move both actuator rods simultaneously over an axial height that corresponds to the short stroke, with one bearing element then continuing its movement so as to terminate its long stroke by pivoting and turning the pivot member about the bearing element that is blocked in position as a result of the second actuator rod already being fully depressed.
