Title:
ROTARY MECHANISM
Document Type and Number:
WIPO Patent Application WO/2019/086924
Kind Code:
A1
Abstract:
This invention reveals a novel rotary mechanism. The proposed mechanism is different and novel compared to existing rotary mechanisms where there is a rotating cam or a cam shaft designed to open and close the ports of the engine by way of pushing valves at pre-determined positions. In the proposed method, the cam is designed in such a way that the ports get opened and closed when the rotating cam locks into a particular position determined by another external shaft connected to the main shaft. The mechanism can be used in many applications. Some of them are external combustion engines, internal combustion engines, and non- fuel thrust engines.

Description:
Title: ROTARY MECHANISM

Background of the Invention

There are two types of engines in practice. One uses liner motion converted to rotary motion connected via a cam shaft to rotate a shaft. The other uses rotary motion itself to rotate a shaft.

In the engines that uses rotary motion, a rotor is pushed around a circle by some force. The force is generated by a compressed gas/ air, burned fuel or, pressurized liquid or steam.

In such rotor engines, there is a rotor positioned inside a stationary housing and the rotor is designed in such a way that it opens and closes inlet and outlet ports, respectively, by pushing valves using a special cam mechanism attached to the rotor.

In this invention, a novel cam mechanism to open the ports is introduced.

The mechanism can be used in conjunction with many mechanical operations where opening and closing of ports is required. Some examples are internal combustion engines, external combustion engines, and non-fuel thrust based engines.

Description of the Invention

The invention is described using the drawing described below.

Figure 1 is the isometric view of the engine.

1. Common housing of the engine

2. Housing of the stator

3. Housing of the external shaft solidly connected to the housing of the stator

4. Inlet port

5. Outlet port

6. Side cover of the common housing

7. A flywheel

8. Rotating shaft with a solidly connected gear wheel 9 in the rotor

9. Gear wheel solidly attached to shaft 8

10. Externally connected shaft with a solidly connected gear wheel 11, connected to the main shaft 8 in the rotor through the interconnecting gear wheels 9 and 11

11. Gear wheel solidly attached to shaft 10

12. Specially cut cam locking arrangement solidly connected to shaft 10

13. Rotor with a special cam 14

14. Special cam interlocking with rotating cam locking arrangement when they are aligned while in motion

15. Bearings

Figure 2 is the cross-sectional view at the cross-section A-A in the isometric view. The same numeral used in the isometric view are used to describe the components. Figure 3 is the cross-sectional view of the cross-section B-B of the isometric view. The same numerals used in the isometric view are used to describe the components. Figure 3 is composed of 6 sub figures 3.1, 3.2, 3.3, 3.4, 3.5 and 3.6. Each of the figures depict the position of the cam as it moves in the anticlockwise direction.

3.1 Protruding cam is at the bottommost position. Inlet port 4 is open and the thrust generated by internal combustion, external combustion or non-fuel thrust is perpendicularly acting on the cam surface.

3.2 An intermediate position of the cam where the inlet port is opened and the thrust is acting on the cam while the outlet port is closed.

3.3 At this point, both the inlet and outlet are open but the cam keeps moving due to the momentum.

3.4 An intermediate position where both inlet and outlet are opened. The cam keeps moving in the anticlockwise direction.

3.5 The last position in the anti-clockwise movement where both inlet and outlet ports are opened.

3.6 At this point, inlet is opened while the outlet is closed and the thrust is acting on the surface of the cam.

The operation of the engine is described below in sequence of actions.

1. A thrust is inserted into the inlet port 4. The trust can be generated by the pressure of a burnt fuel, or by a compressed gas or by a pressured liquid or steam.

2. The inserted thrust is acting upon the surface of the cam 14 thereby rotating it in anti-clockwise direction.

3. Until the cam 14 reaches the outlet port 5, the externally connected cam locking mechanism is not allowing the pressure in the chamber to be released.

4. As soon as the cam comes to the end of the outlet port, the cam 14 gets locked in the locking mechanism 12 and due to the momentum, the cam rotates to the start of the inlet port.

5. As the cam progresses through the inlet port, the outlet port gets closed by the interlocking cam mechanism.

6. Now the cam is again pressurized and it rotates and the process continues.

The cam and the interlocking section can be of any triangular shape but the best performance is achieved when the thrust inserted side is flat.
