Connector for transferring fluid and method of use

摘要

A connector for transferring fluid and method therefore. The connector may have a first port, a second port, and a third port which may be coupled together at a main channel with a first valve element therein controlling fluid flow through the first port. The first valve element is supported by a valve element support positioned between the first port and the third port, and the second port joins the main channel to provide a fluid path around the first valve element and through the third port.
