A pressure generation apparatus comprises a fixed means (1) in a fluid and a movement means(2) moving relative to the fixed means (1), opposite inner surfaces of the movement means (2) and the fixed means (1) contacting with each other, or there is a relatively small gap (3) therebetween, and outer surfaces of both the movement means (2) and the fixed means (1) contacting the fluid. A pressure generation method using the pressure generation apparatus is also provided. When the movement means (2) moves relative to the fixed means (1), a force of fluid on the outer surface of the movement means (2) on the movement means (2) is less than a force of fluid on the outer surface of the fixed means (1) on the fixed means (1), so that the fluid produces a pressure on the pressure generation apparatus. |
