Positive pressure liquid transfer and removal system configured for operation by a hand and by a foot

A positive pressure liquid transfer and removal system for pumping liquid from a container to a destination, said container having an aperture opening to the interior thereof, comprising:

• fitting means for engaging said aperture in said container in sealed relation thereto, said fitting means including ingress and egress ports in flow communication with each other;
• liquid delivery hose means releasably connectable at one end thereof to said egress port of said fitting means;
• liquid intake hose means releasably connectable to said ingress port of said fitting means and insertable into liquid within said container;
• foot operable pump means;
• pressure hose means for connecting said pump means to said container in sealed relation thereto for pressurizing said container;
• and
• hand operable valve means comprising:
• a housing with a hand operable actuating lever pivotally connected at one end thereof to said housing;
• a valve element within said housing, said valve element including liquid inlet and outlet ports, said liquid inlet port communicating with the other end of said liquid delivery hose means, said outlet port communicating with an outlet of said valve means;
• a valve member within said valve element, said valve member being displaceable between a first position normally blocking liquid flow from said inlet port to said outlet port and a second position permitting liquid flow from said inlet port to said outlet port, said valve member including an end surface engageable with the opposite end of said actuating lever;
• and
• compression spring means within said valve element and normally biasing said valve member to said first position;
• and
• wherein said valve member further includes a shaft portion with said end surface at one end thereof, and a plunger portion at an end opposite said one end, said plunger portion being cup-shaped and of a diameter greater than that of said shaft portion, said cup-shaped plunger portion receiving one end of said compression spring means, the opposite end of said compression spring means being engageable with said housing;
• whereby foot operation of said pump means will pressurize said container, permitting liquid to flow under pressure from said container, through said liquid intake hose, said fitting means, and said liquid delivery hose means, to and through said valve means as controlled by said actuating lever and said valve member for delivery to said destination.
