Embodiment 1

[0019] see figure 1 The shown pressure generating device includes a fixed part 1 and a moving part 2, both of which are discs, and the two discs are coaxial. The inner surface 21 of the movable part is opposite to the inner surface 11 of the fixed part up and down, and there is lubricating oil in the gap 3 between the two opposite inner surfaces, and the width of the gap 3 is less than 0.5mm. A driving mechanism (not shown) for driving the movable member to rotate relative to the fixed member around the fixed member axis 4 is connected to the movable member. During the rotation of the movable member 2, the width of the gap 3 remains substantially constant. The fixed part 1 and the moving part 2 are placed in the air, and the outer surface 22 of the moving part and the outer surface 12 of the fixed part are both in contact with the air. When the moving part rotates relative to the fixed part, since the gap 3 is very small, the force of the lubricating oil on the inner surface...

Embodiment 2

[0023] see figure 1 The pressure generating device shown includes a fixed part 1 and a moving part 2, the fixed part 1 is a half ring, the moving part 2 is a shaft, and the half ring is coaxial with the shaft (the axis coincides). The inner surface 21 of the movable part is opposite to the inner surface 11 of the fixed part up and down, and there is lubricating oil in the gap 3 between the two opposite inner surfaces, and the width of the gap 3 is less than 0.5mm. A driving mechanism (not shown) for driving the movable member to rotate relative to the fixed member around the fixed member axis 4 is connected to the movable member. During the rotation of the movable member 2, the width of the gap 3 remains substantially constant. The fixed part 1 and the moving part 2 are placed in water, and the outer surface 22 of the moving part and the outer surface 12 of the fixing part are both in contact with the water. When the moving part rotates relative to the fixed part, since the ...

Abstract

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.

Description

technical field [0001] This patent relates to a pressure (or thrust) generating device and a generating method for generating pressure (or thrust). Background technique [0002] For the propeller of a helicopter or the propeller of a ship, in order to generate greater thrust, the area of ​​the blade needs to be large enough. For this reason, the propeller is often made very long to increase the thrust. At the same time, the disturbance noise is very large when the propeller rotates. For these thrust generating devices, the volume is large, the noise is large, the manufacturing process is complicated, and the cost is high. Contents of the invention [0003] The purpose of the present invention is to provide a pressure generating device with simple structure, small volume, low noise and convenient preparation. [0004] The pressure generating device of the present invention comprises a fixed part located in the fluid, a moving part that moves relative to the fixed part, the...
