ABSTRACT:
An actuator pump has one or more colinear piston cylinders (2, 3, 25) in a cylinder housing (1) in which change of volume is provided by reciprocative relationship of colinear pistons (4, 5, 23, 24,) in the colinear piston cylinders. One or more travel guides (6, 8) in sliding contact with guide cylinders (7, 9) in the cylinder housing are parallel to the travel guides. The colinear pistons and travel guides are attached to pump bases (10, 11) at opposite ends of the travel guides. Inward-pressured rings (14, 26), outward-pressured rings (29), fluid conveyances (16, 19, 30, 31), valves (36) and attachment components (21) for reciprocative actuation are provided selectively for particular design requirements.
