Abstract
A trigger actuated liquid dispensing pump assembly has a locking mechanism for preventing rotation of the discharge nozzle from its discharge closed position in either direction about its central axis. The locking mechanism comprises a locking element having at least one protrusion extending into a gap formed by a side wall of the shroud cover spaced from an opposing side wall of the trigger lever. A pair of such protrusions may be provided, the second protrusion of the pair extending into another gap formed by an opposing shroud cover side wall and an opposing side wall of the trigger lever. The protrusion or protrusions engage stop means comprising surfaces of the side walls forming the gap or gaps for preventing nozzle rotation in either direction. Alternatively, the locking mechanism has a pair of fingers straddling the trigger lever without underlying the shroud cover side walls, the fingers engaging flat opposing side walls of the trigger for resisting nozzle rotation in either direction about its central axis.
