Abstract
A manually charged fluid dispenser includes a charging cylinder disposed in the mouth of a bottle and a manually reciprocable piston carried on a charging rod which extends out each end of the cylinder. The charging rod has a differential diameter for providing hydraulic return thereof by fluid pressure in the charging tube after manual charging of the tube. The charging tube is in fluid communication with a spray nozzle mounted on the bottle and tube through a ball valve which is selectively unseatable by a cam actuated by a slidable trigger, which is hydraulically biased by a piston which is in connection with pressurized fluid at the ball valve. An alternative embodiment of the charging cylinder provides a charging rod slidable in a draw tube disposed above an end of a charging cylinder and a piston slidable therein so that fluid pressure in the cylinder will return the rod to its rest position.
