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