PURPOSE:To enable to reduce the thickness of a fluid machine, by disposing a movable plate in a fluid passage in the manner of restricting the fluid flow, and forming a nozzle or the like with an inlet and an outlet ports having different diameters, so that fluid in the fluid passage can be conveyed by moving the plate reciprocally in the fluid passage. CONSTITUTION:A movable plate 2 movable in the direction of a fluid passage is disposed in a fluid pipe 1 filled with a fluid to be conveyed, perpendicularly to the length of the fluid passage. The movable plate 2 is formed with a nozzle 3 with an inlet and an outlet ports (a), (b) having different diameters. With such an arrangement, when the movable plate 2 is reciprocated once, an amount of fluid (Qa-Qb) is conveyed from left to right in the drawing, since the amount of fluid Qa passed through the nozzle 3 when the plate 2 is moved in the direction shown by a dotted-line arrow and the amount of fluid Qb passed through the nozzle 3 when the plate 2 is moved in the direction of a solid-line arrow hold the following relationship; Qa>Qb. |
