Abstract
A multiline check valve assembly has an elongated body which defines a fluid passageway and which is formed with a plurality of valve cavities that are in fluid communication with the fluid passageway. Each valve cavity has a resilient valve element disposed within the cavity and each valve element rests in the cavity with one end against a protrusion disposed in the cavity for centering the element within the cavity. The resilient valve element is biased to urge its other end against a valve seat that surrounds an opening to the valve cavity to create a fluid tight seal with the valve seat and close the opening. In addition, an access port is formed circumferentially around both the valve seat and opening to establish a fluid communication path through the access port to the fluid passageway in the body when the valve element is separated from the valve seat. Specifically, when an appropriate fluid line connector is inserted into the access port to urge against the resilient valve element, the valve element is deformed away from the valve seat to complete the fluid communication path between the access port and the fluid passageway. In an alternate embodiment, the body of the valve is substantially cube-shaped and has a plurality of valve cavities disposed transversely therein, each of the valve cavities being in fluid communication with the fluid passageway that is formed by the valve body.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
