Abstract
A connector for transferring fluid, the connector may have a first port, a second port, and a third port which may be fluidly coupled together at an internal chamber with a first valve element therein controlling fluid flow through the second port. The connector can have ribs extending along the connector to provide a fluid path around the valve element and between the first port and the second port. The valve element can separate the internal chamber into an air chamber and a liquid chamber, and the third port can be continuously coupled to the liquid chamber regardless of a position of the valve element.
Claims20
A connector for transferring fluid, the connector comprising:
- a base having a first port and an air passage,
- a cap having a second port, an internal chamber defined between the base and the cap, and ribs extending longitudinally along an inner surface of the cap and between the second port and the base, the internal chamber fluidly coupled to the first and second ports;
- and
- a valve element within the internal chamber, the valve element comprising a head portion configured to seal the second port, a body portion having a cavity;
- wherein the valve element separates the internal chamber into an air chamber and a liquid chamber, the air chamber in fluid communication with the air passage, and the liquid chamber in fluid communication with the first port and having a fluid path between the ribs and the valve element.
A connector for transferring fluid, the connector comprising:
- a housing having a first port, a second port, an inner surface forming an internal chamber fluidly coupled to the first and second ports, and ribs extending longitudinally along the inner surface between the first port and the second port;
- and
- a valve element within the internal chamber, the valve element comprising a head portion and a body portion, the head portion configured to seal the second port, and the body portion comprising a cavity and configured to seal a perimeter of the cavity to separate the internal chamber into an air chamber and a liquid chamber, the air chamber in fluid communication with an outside of the housing, and the liquid chamber in fluid communication with the first port and having a fluid path between the ribs and the valve element.
