Abstract
A water gun, water pump, or the like which includes a housing having a reservoir for fluid. A chamber within the housing has a plunger slidably and sealably received within the chamber. A valve is in operable position with respect to the chamber whereby in a first orientation of the housing, displacement of the plunger evacuates fluid from the reservoir and forces fluid through the chamber in a first direction and in a second orientation of the housing, displacement of the plunger forces fluid through the chamber in a second direction and fills the reservoir with fluid.
