Fluid Handling Device Having Valve

A liquid flow device for selectively dispensing liquid or evacuating liquid, the device comprising:

• a container defining an interior and an opening in fluid communication with the interior;
• a lid configured to be mounted on the container over the opening;
• passaging supported by the container when the lid is mounted on the container, the passaging including:
• a gas supply passage configured to be fluidly connected to a source of pressurized gas;
• a pressurization passage configured to be fluidly connected to the gas supply passage, the pressurization passage being positioned to deliver pressurized gas from the gas supply passage to the interior of the container when the lid is mounted on the container;
• an evacuation passage including a ventrui and configured to be fluidly connected to the interior of the container when the lid is mounted on the container, the evacuation passage being configured to be fluidly connected to the gas supply passage to convey pressurized gas from the source of pressurized gas through the venturi to create vacuum pressure in the interior of the container;
• and
• a liquid passage configured to be fluidly connected to the interior of the container, and fluidly connected by the interior of the container to the pressurization passage and the evacuation passage when the lid is mounted on the container;
• and
• a mode selector valve fluidly connected to the pressurization passage and the evacuation passage, the mode selector valve being adjustable between a dispensing mode configuration and an evacuation mode configuration, the mode selector valve in the dispensing mode configuration blocking gas flow in the evacuation passage, and the mode selector valve in the evacuation mode configuration blocking gas flow in the pressurization passage, the mode selector valve including an actuator movable from a dispensing position to an evacuation position to adjust the mode selector valve from the dispensing mode configuration to the evacuation mode configuration, the actuator configured to, as the actuator is moved from the dispensing position toward the evacuation position, cause the mode selector valve to block gas flow in the pressurization passage and cause the mode selector valve to unblock gas flow in the evacuation passage.

• a mode selector valve fluidly connected to the pressurization passage and the evacuation passage, the mode selector valve being adjustable between a dispensing mode configuration and an evacuation mode configuration, the mode selector valve in the dispensing mode configuration blocking gas flow in the evacuation passage, and the mode selector valve in the evacuation mode configuration blocking gas flow in the pressurization passage;
• wherein the mode selector valve includes first and second selector valve channels, the first selector valve channel crossing the evacuation passage, and the second selector valve channel crossing the pressurization passage, the mode selector valve including first and second valve member portions, the first valve member portion being slidable in the first selector valve channel between an open position in which the first valve member portion permits gas flow through the evacuation passage and a closed position in which the first valve member portion blocks gas flow through the evacuation passage, the second valve member portion being slidable in the second selector valve channel between an open position in which the second valve member portion permits gas flow through the pressurization passage and a closed position in which the second valve member portion blocks gas flow through the pressurization passage;
• wherein each of the first and second valve member portions includes a passage seal configured to sealingly engage the selector valve body across the respective one of the evacuation and pressurization passages to close the respective passage;
• wherein each of the first and second valve member portions has a slide axis and each passage seal is configured to sealingly engage the selector valve body continuously about a sealing hoop that extends around the slide axis of the respective valve member portion, wherein each of the sealing hoops is oriented substantially in a respective seal plane oriented at a respective skew angle with respect to the slide axis of the respective valve member portion, each of the skew angles being in an inclusive range of from about 20 degrees to about 70 degrees.
