Abstract
A dispensing pump means has an operating pusher for effecting a pump stroke and a control means for selectively varying the length of stroke. The control includes a neck on a base for receiving the operating pusher, cooperating grooves and abutment shoulders guiding the pusher and setting its maximum stroke. At least one projection positively slides in a selected one of a plurality of grooves of different lengths, the projection being positioned out of the grooves and in front of the ends of the grooves in an initial position of the pump, i.e., prior to the pump stroke. Axially preceding the ends of the grooves, an arched path extends around the pump axis and guides the projection during manual rotation of the operation pusher as the projection is positioned over the selected groove.
