Abstract

The moment pump (10) of the present invention includes a flexible container (12) having an outer wall (14) and two opposing end walls (16, 18) attached thereto. The container (12) is made of a resilient material and has a preformed, non-biased shape. A pair of one-way valves (20) is operably attached to the container (12) and provides for the flow of a liquid therethrough. A first actuator rod (22) has fixedly attached on one end a first biasing object (24) and on the other end a restraining member (26). The first end wall (16) is attached to the first actuator rod (22) between the first biasing object (24) and the restraining member (26). A second actuator rod (30) has fixedly attached on one end a second biasing object (28) and on the other end a transfer housing (32). The second actuator (30) slidably passes through the second end wall (41). The transfer housing (32) has an interior chamber (34) into which the longitudinal restraining member (26) of the first actuator travels in confinement, not being able to leave the interior chamber (34). The interior chamber (34) prevents the longitudinal restraining member (26) from being removed therefrom. The transfer housing (32) is cylindrically shaped about the interior chamber (34) and has open end (39) into which the first actuator enters (22). Attached between the exterior wall (36) of the transfer housing (32) and the inner surface (38) of the outer wall (14)of the container (12) is a plurality of biasing tension actuators (40) divided into two sets of tension actuators, a clockwise set and a counterclockwise set. Movement of the transfer housing (32) by the second actuator rod (30) or movement of the container (12) by the first actuator rod (22) causes the outer wall of the container to be pulled in a direction to the transfer housing (32) thus decreasing the volume therein. This acts as the pump action. Upon release of the biasing force, the outer wall of the container (12) returns to its resilient shape and this action draws in fluid into the container (12).
