Liquid transfer system with flow control

In a liquid transfer system that includes a liquid container having a reservoir and an access opening to the reservoir, and further includes an extractor valve assembly connected to the liquid container proximate the access opening, the extractor valve assembly including a valve member movable from a closed position blocking liquid flow through the extractor valve assembly to an open position permitting liquid flow therethrough;

• the improvement comprising a coupler assembly removably coupled with the extractor valve assembly, said coupler assembly comprising:
• (a) a generally cylindrically shaped coupler body having an upper outlet port;
• (b) actuating means interconnected with said coupler body for moving the valve member of the extractor valve assembly from a closed position to an open position, said actuating means comprising:
• (i) an actuating sleeve slidably movable within said coupler body, said actuating sleeve having an upper chamber and a lower chamber having an inlet in communication with the reservoir of the liquid container;
• and
• (ii) an actuating handle pivotally connected to said coupler body and associated with said actuating member for moving said actuating member from a first upper position to a second lower position;
• (c) coupler valve means scalably disposed within said lower chamber of said actuating sleeve for controlling liquid flow between said upper and lower chambers thereof, said coupler valve means comprising;
• a generally ring shaped insert sealably and slidably mounted within said lower chamber of said actuating member, said insert comprising;
• a. a skirt having a plurality of circumferentially spaced, liquid passageways communicating with said inlet port of said lower chamber of said actuating sleeve;
• b. a base wall connected to said skirt portion and defining in cooperation therewith an internal chamber, said base wall having a peripheral surface defining a valve seat;
• and
• (ii) a valve member connected to said insert, said valve member being movable in response to liquid flowing from a first position in sealing engagement with said valve seat to a second, open position permitting liquid flow toward said outlet portion of said coupler body, said valve member blocking liquid flow toward said inlet of said lower chamber of said actuating sleeve when said valve member is in said first position.

A liquid transferring stem comprising:

• (a) a liquid container leaving a liquid reservoir and an access opening communicating with said liquid reservoir;
• (b) an extractor valve assembly connected to liquid container proximate said access opening, said extractor valve assembly including a valve member movable from a closed position blocking liquid flow through the extractor valve assembly to an open position permitting liquid flow therethrough;
• (c) a coupler assembly removably connected to said extractor valve assembly, said coupler assembly comprising;
• (i) a generally cylindrically shaped coupler body having an upper outlet port;
• (ii) actuating means interconnected with said coupler body for moving the valve member of the extractor valve assembly from a closed position to an open position, said actuating means comprising:
• a. an actuating sleeve telescopically movable within said coupler body, said actuating sleeve having an upper chamber and a lower chamber said lower chamber having an inlet in communication with said liquid reservoir of said liquid container;
• b. an actuating handle pivotally connected to said coupler body for moving said actuating sleeve from a first upper location to a second lower location;
• and
• (iii) coupler valve means disposed within said lower chamber of said actuating sleeve for controlling liquid flow between said upper and lower chambers thereof, said coupler valve means comprising:
• a. a generally ring shaped insert sealably and slidably mounted within said lower chamber of said actuating member, said insert comprising a skirt-like portion, an apertured base wall connected to said skirt-like portion and defining in cooperation therewith an internal chamber, said base wall defining a valve seat, said skirt-like portion and said base wall being provided with a plurality of liquid passageways interconnecting said internal chamber with said inlet of said lower chamber of said actuating sleeve;
• and
• b. a valve member connected to said insert, a peripheral portion of said valve member being movable in response to liquid flowing through said liquid passageways, said peripheral portion of said valve member being movable from a first position in sealing engagement with said valve seat to a second, open position permitting liquid flow toward said upper outlet port of said coupler body, said valve member blocking liquid flow toward said inlet of said lower chamber of said actuating sleeve body when said valve member is in said first position.
