A multi-directional pump is disclosed generally comprising a housing with
inlet and outlet ports, a pumping device disposed therein, a first
chamber in fluid communication with the inlet port, and a second chamber
in fluid communication with the first chamber. The first and second
chambers are both in direct fluid communication with the outlet port,
such that a double pumping effect is achieved while some of the fluid is
compressed in multiple stages. In certain embodiments, one or more
sealing mechanisms can be activated when particular conditions are
desired in order to seal the first conduit by which the first and second
fluid chambers communicate, or by which the second fluid chamber
communicates with the inlet port, such that a standard double or single
pumping effect is achieved.
