A recently filed patent (Publication Number: US20230311377A1) describes a fluid dispenser with unique features. The fluid dispenser includes a housing with a first fluid inlet, an internal chamber, and a discharge port for dispensing fluid. It also has a dispensing fluid inlet and a dispensing fluid passage system to carry the dispensing fluid to the discharge port. The dispenser further includes a valving rod that can move within the internal chamber to control the flow of the first fluid product.

The dispensing fluid passage system consists of a first passageway and a second passageway. The first passageway carries the dispensing fluid in a first direction, while the second passageway carries the dispensing fluid in a different second direction. The second passageway has a distal end near the discharge port, allowing the dispensing fluid to exit the dispenser in close proximity to the discharge port.

The valving rod moves longitudinally from an open position to a closed position, and the first direction of the dispensing fluid is parallel to this longitudinal direction. The second direction of the dispensing fluid is at an angle with respect to the longitudinal direction, which is neither parallel nor perpendicular to it.

The housing of the fluid dispenser includes a cavity closed by a stopper, and the first passageway is a bore extending from the cavity. The second passageway is a bore that extends through the housing from a side or a protrusion on the side. The axes of the first and second bores intersect each other and are not parallel.

The housing also features an annular groove in the internal chamber near the discharge port, where the distal ends of the second passageway and a potential fourth passageway open. The dispenser may also have additional passageways, such as a third passageway and a fifth passageway, to carry the dispensing fluid in different directions.

Overall, this patent describes a fluid dispenser with a unique dispensing fluid passage system and valving rod mechanism. The design allows for precise control of fluid flow and dispensing, making it suitable for various applications in industries such as healthcare, automotive, and household products.
