ABSTRACT:
A dosing mechanism in the form of a manually operable, single-acting piston pump, which dispenses a given quantity of a substance, e.g. in atomized form, during each actuating stroke has a counter. For this purpose, a counting ring mounted in rotary manner on a base part is provided, which is advanced by one step per actuating stroke by an indexing device with cooperating and correspondingly bevelled ribs, so that in each case a different character in the counting ring appears at a window in the actuating pusher casing. Two projections cooperating with one another in a given position of the counting ring form a locking device against further actuation of the atomizing pump, when a given number of strokes have been performed.
