Abstract: A fluid dispensing device comprises a housing body, a reciprocating piston fluid pump, a primary drive element, a wobble assembly and a spray tip. The reciprocating piston fluid pump has a piston disposed within a pumping chamber inside the housing body. The primary drive element is coupled to the housing body to provide a rotary input. The wobble assembly connects the primary drive element to the reciprocating piston fluid pump to convert the rotary input into reciprocating input to the piston. The spray tip connects to an outlet of the pumping chamber.

Abstract: A fluid dispensing device is provided in the form of a spray container. The spray container is formed with a protruding sump region formed along the bottom of the container. The thickness of the bottom of the container is tapered such that the lowest point in the upright container is in the distal end of the protruding sump region. The container further includes a rotating trigger spray head mounted on the container top and a rigid suction tube extending from the container top into the protruding sump region.

Abstract: A spray bottle has a ball swivel joint enabling angular orientation of the spray head with respect to the bottle. Both liquid and air are conducted between the pump and the bottle in separate passageways in the swivel joint, thus enabling use of a conventional pump. These passageways may be spaced apart or substantially concentric. A highly flexible pickup hose has a weight at its distal or pickup end, so that the distal and remains immersed in liquid, even when the spray bottle is inverted. In alternative embodiments, the pickup hose is bendable, rather than highly flexible. Tightening a cap adjusts tension on the swivel joint, thus varying pressure required to adjust spray head angularity or to immobilize the spray head at a desired angularity. The swivel joint may include one or more ball members.

Abstract: A pump sprayer for pharmaceutical or cosmetic products provides for consistent spray regardless of the orientation of the container. A gravity-actuated valve element coacts with a valve seat to close a secondary passage to the pump when the container is in a normal upright position. In an inverted position the valve opens and the pump intakes from the secondary passage which draws from the area of the top of the container, opposite the primary pump dip tube intake at the base of the container. The valve casing which includes the valve seat has an insertion aperture for the valve element, as well as an axial slot to insure communication of the secondary passage with the pump when the container is in the inverted position.

Abstract: The thrust piston pump of a delivery apparatus for liquid media and the like is provided with a valve arrangement in the suction passage. The valve arrangement has two valve seats acting in opposing manner and is associated with a single common valve body. This permits a rapid transfer of the valve body into the closed position engaging on the valve seat, particularly during operation in an inverted position. In addition, the discharge passage has a mechanically openably discharge valve which can be simply opened by displacing the actuating head of the pump with respect to a collar of the pump piston.

Abstract: A manually actuated upright/inverted pump sprayer having a piston controlled container vent path, an auxiliary liquid intake port for inverted spray being spaced closer to the inner side of the container seal gasket compared to the spacing of the container vent port therefrom so as to preclude the spontaneous ingestion of air bubbles from the open vent path into the pump chamber through such intake port during inverted spray.

Abstract: A windshield washer having a jet nozzle adapted for ejecting a washing liquid to a windshield, a first reservoir for containing a first liquid such as water, a second reservoir for containing a second liquid such as a detergent solution, and a pump having a rotor for feeding the first or second liquid to the jet nozzle. By rotating the rotor selectively in the forward or reverse direction, the desired first or the second liquid is ejected from the jet nozzle as the washing liquid.
