ABSTRACT:
A device for transferring fluid with minimum fluid displacement includes a valve internal chamber adapted for receiving an actuator therethrough for facilitating introduction of fluid into the valve internal chamber. A biased member abuts against either a compressible gas or an ambient atmosphere, and is adapted for being moved by the actuator. Movement of the biased member results in displacement of either the compressible gas or the ambient atmosphere to thereby offset a displacement of fluid in the valve internal chamber that was introduced by insertion of the actuator into the valve internal chamber. A valve outlet port is adapted for outputting fluid from the valve internal chamber. The valve outlet port is configured in fluid communication with the valve internal chamber at all times, and is adapted for allowing fluid to freely flow between the valve internal chamber and the valve outlet port.
