<p>A trigger-type device for operating a pump of the axial displacement piston type against a bias spring, in order to spray liquids out of a handheld container, said pump having a delivery head (23) which is movable axially with the piston (7) and provided with a delivery conduit (22) set at an angle to the displacement axis (X-X) of the piston (7) and lying in the same plane where the angular movement of the trigger lever (32) takes place. The device includes a rocker lever (30) which converts the angular movement of the trigger lever (32) into a corresponding axial displacement of the delivery head (23) to thereby drive the pump piston (7) against the bias spring and produce the spray. <IMAGE></p> |
