The pump systems include a moveable piston housed in a main chamber and inlet and outlet valves located at one end of the main chamber, where the inlet and outlet valves open and close in response to movement of the piston.
Claims20
A pump system comprising:
- a housing comprising a main chamber and an outlet channel, wherein the main chamber has a first end and a second end;
- a piston moveable within the main chamber, wherein a portion of the piston is configured to move at least partially out of the first end of the main chamber;
- an inlet valve located at the second end of the main chamber and in fluid communication with the main chamber and an inlet opening, wherein the inlet valve is configured to open when the piston moves away from the inlet valve and is configured to close when the piston moves toward the inlet valve;
- and
- an outlet valve located at the second end of the main chamber and in fluid communication with the main chamber and the outlet channel, wherein the outlet valve is configured to open when the piston moves toward the outlet valve and is configured to close when the piston moves away from the outlet valve.
A method of removing liquid from a container with a pump system, the pump system comprising a main chamber, a piston moveable within the main chamber, an inlet valve in fluid communication with the main chamber, an outlet valve in fluid communication with the main chamber, and an outlet channel in fluid communication with the outlet valve, the method comprising:
- moving the piston away from the inlet valve to close the outlet valve and draw liquid from a container into the main chamber through the inlet valve;
- moving the piston toward the outlet valve to close the inlet valve and push liquid from the main chamber into the outlet channel through the outlet valve.
