摘要：A valve assembly is provided that can operate to fill and/or refill a containerwith, for example, a liquid while venting excess vapor from the container associated withthe liquid to relieve pressure in the container created by the liquid, and that can operateto introduce a carrier gas into the container for use in retrieving vapor products from theliquid within the container. The valve assembly includes a housing defining two bores andmultiple ports extending through the housing in communication with the bores. A valvespool is located within each bore to selectively control movement through the housingof the liquid, the excess vapor associated with the liquid, the carrier gas, and the vaporproducts retrieved from the liquid by the carrier gas.
