  • Patent number: 12357753
    Abstract: A flow control device includes a housing having a primary valve body defining a primary inlet and an outlet, a secondary valve body defining a secondary inlet and a chamber defined by an inner circumferential surface of the housing and fluidly connecting the primary and secondary inlets with the outlet. The primary and secondary inlets share a common central axis perpendicularly disposed to a central axis of the outlet. A valve member is reciprocally mounted in the chamber to block fluid communication between the secondary inlet and the outlet when fluid pressure into the primary inlet is higher than fluid pressure into the secondary inlet, and block fluid communication between the primary inlet and the outlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.

  • Publication number: 20220133983
    Abstract: A drip chamber device may include a housing including an inlet and an outlet disposed downstream of the inlet, and a chamber defined by an inner circumferential surface of the housing. The chamber may fluidly connect the inlet with the outlet. A valve member may be disposed in the chamber to move between (i) a closed state where fluid communication between the inlet and the chamber is blocked, and (ii) an open state where fluid communication between the inlet and the chamber is not blocked, based on a level of fluid within the chamber.

  • Publication number: 20220088302
    Abstract: A flow control device may include a housing having a primary valve body defining a primary inlet and an outlet of the flow control device, a secondary valve body defining a secondary inlet of the flow control device, and a chamber defined by an inner circumferential surface of the housing. The primary and secondary inlets may share a common central axis, and a central axis of the outlet may be perpendicularly disposed relative to the common central axis. The chamber may extend between the primary and secondary valve bodies for fluidly connecting the primary and secondary inlets with the outlet.
