A fluid displacement pump includes a rigid hollow body having a first open end, a flexible partition disposed within the hollow body adjacent the first open end to create a variable volume fluid chamber between the partition and the hollow body, and an actuator acting upon the flexible partition. A movable piston including a shaft connected to the actuator and a head connected to the partition may be disposed within the hollow body. The rigid housing acts as a guide for the piston head. A piston stop may be provided for limiting the movement of the piston. Further, a movable mass may be disposed within the hollow body and controlled by either a linear motor or a pulley system. |
