Abstract (en)
[origin: WO9904140A1] A volumetric-displacement-maximizing device includes a molded slider (12) bidirectionally movable within an elongate cavity (14) formed within a molded body (16). The body (16) also includes a port structure (18) with an output port (18a) and an input port (18b), each providing channels for communication between the cavity (14) and an extra body location. A power device (22) causes the slider (12) to move bidirectionally within the cavity (14), and the clearance between the slider (12) and the cavity (14) exceeds 0 - but is less than approximately 0.0003 inches. The device of the invention takes several alternative forms including a fluid mechanical device, and has several alternate applications as a pump, valve, or motor. The invention also includes various method features.
