Abstract (en)
[origin: US4566611A] A pump for dispensing fluids and like media, having a pump casing including structure forming a counter locking means, a pusher for operating the pump, movable from a rest position into the pump casing to deliver a pumping stroke responsive to manual depression of an operating surface formed in an end face of the pusher, a locking mechanism for the pusher formed by the operating surface and a locking portion rigidly affixed to the operating surface, the locking mechanism being pivotally attached to the pusher to enable movement of the locking portion into and inwardly of a locking position relative to the counter locking means of the pump casing, whereby each pumping stroke must be preceded by pivotal movement of the locking mechanism, and, resilient structure for automatically urging the locking portion outwardly, into the locking position, after each pumping stroke, whereby pressure exerted upon any portion of the end face other than the operating surface will be ineffective for accidentally operating the pump and delivering an unwanted pumping stroke.
