Abstract

PURPOSE:To make it possible to generate large power by reducing inflow of pressured fluid by means of duplicate work of a force applying point, while generating differential motion by means of main input of pressure, in an equally pressured closed circuit which is made by making thrust of plural liquid-operated cylinders oppose to each other. CONSTITUTION:When a pump 2 is activated by an electric motor 1, a going electromagnetic valve 3 is made to be on, and a going pressuring circuit 5 and a circulating circuit 28 are communicated with each other, going side cylinders 8, 9 are equally pressured. At that time, cylinder thrust of the cylinders 8, 9 is balanced with opposing thrust in the direction of an arrow 24 via gears 18, 19, so that composite power is reduced and the cylinders are in resting condition. Therefore only thrust of a cylinder 7 is generated, and the cylinder 7 is made to advance in the direction of an arrow 21. At the time, the cylinder 9 is driven in the advancing direction via a rack shaft 16 which meshes with a balancing pinion of a small diameter 31, and a total amount of a discharged amount from the cylinders 8, 9 is provided as circulating amount to the propelling cylinder 7, so that large differential thrust is generated to the propelling cylinder 7.

Description

[Detailed description of the invention] (a) The present invention relates to a fluid engine.

(b) An object of the present invention is to provide an input-saving fluid generator that generates motion using liquid pressure as the main input.

(c) The feature is that a closed circuit output motion is generated by equal pressure of the opposing thrust of the cylinder.

(2) The principle and structure of the motion that generates output motion by pressurizing a closed circuit will be explained using the example shown in Figure 1.

Figure 1 (a) shows 19. The crankshaft of 24. This indicates the state immediately before starting.

First, 1. Start the electric motor and 2. Rotate the pump, 3. If you turn on the forward solenoid valve, 5. forward pressurization circuit and 23. 9.8.7. The reciprocating cylinder of is equally pressurized.

The internal pressure of each forward cylinder, which is pressurized equally, generates thrust in the direction of the arrow.

Since the inside of each cylinder is filled with liquid,
Instantly boosts the pressure to 100s/at.

That is, 2. The pump rated output is set to pressure, 100 s/U discharge rate 60 t/@l-motor input 10 KIM.

9, the stationary cylinder is set to have a pressure receiving area of 400CIf a stroke of 100- (this thrust is 40.00C).
It will be 0kg.

The discharge cylinder of 8 is set to have a pressure receiving area of 200a, a stroke of 300a, and an internal volume of 6), and the thrust is 2
It will be 0,000kg.

7, the output cylinder has a pressure receiving area of 200ao' and a stroke of 300■■, so the thrust is 20.000kg.
It becomes.

The thrust directions of the opposing cylinders 8 and 9 are arranged to face each other, and the thrust of 40,000 kg and the thrust of 2
Although the thrust forces of 0,000 kg are opposed, the differential output is maintained to be zero.

8, and 9. Explain the cylinder thrust balance of .

The direction of the thrust of the stationary cylinder in 9. is 16. 17. The small diameter gear of is used as the force application point, and it acts as a pushing state toward the left and counterclockwise with respect to the drawing.

8, the discharge cylinder thrust is 17.18. 15. to the gear shaft to which the gear is fixed. The shaft is attached to the shaft, and the shaft is pulled to the right or clockwise relative to the drawing to rotate, resulting in mutually opposing thrust forces.

18. Fixed to the gear shaft. The diameter of the large diameter gear is 200mm, and the diameter of the large diameter gear is 17mm fixed to the gear shaft. The small diameter tooth of is 10 in diameter.
It is set to 0-.

Next (here, with the position of the rack tooth of 13. meshing with the large diameter gear of 18. as a fulcrum, the distance to the force application point of 15. and 16. is 100.- to the shaft attachment point of 15., and 16. The distance to the point of force is 50-, which acts as a 2:1 lever action.

15. The thrust at the point of force on the axis will be balanced at the top.

Therefore, 9. Cylinder thrust of 40,000 8.
The cylinder thrust of 20.000Kp is well balanced, and the combined output becomes zero.

By installing sliding parts, rolling bearings, etc., gear shafts that have neutralized thrust can move smoothly even when pressurized or when a small amount of external force is applied.

Therefore, only a thrust of 20,000 mm is generated in the output cylinder of 7. whose contact force point is the shaft attachment part, and 10.
Generates a powerful straight-line propulsion motion in the forward direction.

(E) The above is the principle of generating differential motion in a counter-thrust equal pressure circuit.Next, we will explain the matching of circulation volume by differential motion.

7, the stroke of the propulsion cylinder of 300. , 24,
If it moves in the forward direction of , the large diameter gear with a circumference of 600 mm and 18 will rotate once.

Therefore, 17. The small diameter gear also rotates counterclockwise, and 17. The 16° rack axis with the force applied point at the circumference 3001 is scheduled to move to the right, 3001I-.
300 of the gear shaft. , by moving to the left, that is, in the forward direction, the 9.0 cylinder piston shaft becomes stationary with zero stroke.

8, the discharge cylinder is 24. forward direction of 300-
23. Discharge 6 internal fluids when moving.
7. This means that the entire volume of the output cylinder can be recirculated.

The amount of fluid required for the output cylinder in 7. is the same as in 6.During propulsion motion, it is possible to generate output with only pressurized pressure input, without requiring fluid inflow from the pump. .

The above is the second principle of motion of a differential pressure engine.

In other words, by neutralizing the opposing thrust and moving the fluid inside the cylinder in the direction of discharge, uniform pressurization and closed circuit output are achieved.

(H)Next, I will explain about the reciprocating motion.

In the embodiment of FIG. 1, one revolution of the gear causes the forward end 27 to move in the axis 300 of the gear shaft. When this position is reached, the limit switch, cam, etc. are detected, and the forward solenoid valve in 3. is set to OFG, and the backward solenoid valve in 4. is turned on, and the pressure in 5. is reduced. Due to the increase in pressure in the circuit of 6., the reciprocating movement in the direction of 25. starts.

When reaching the backward motion end, the forward thrust movement continues by repeating the above operation again, and the crank rod at 19. (Thus, by rotating the crank wheel at 20. Output can be transmitted to the axis of .

Additionally, as an output method, it is also effective to use a one-way clutch on the output shaft.

(G) Next, I will explain the output calculation in detail.

The formula for calculating the output is Pressure receiving area x pressurized pressure x 7T per second: theoretical output.

Therefore, 200atX 100kg/ar= 20,00
3 including the pause time for pressure switching due to the 0kg solenoid valve number.
In the case of reciprocating 00-m in 0.6 seconds,
6001=0.6 seconds is lm=1 second and 20.000
kgX1mX1. Qsec=20,000kg/m5e
The theoretical output is c, the effective output is 50 n, and 10.00
0 kg/m5ec, and converted to ■, the output will be approximately 98 Akebono. The above values are theoretical values, but compared to pump input, it is clear that it is possible to create a highly efficient, manpower-saving fluid prime mover.

In addition, 14. of the method shown in Figure 1. The output shaft of 17 or 18 is a gear shaft contact type output system, but a rack shaft is used. An output shaft structure in which the force is applied to the gear is also possible.

Furthermore, it is also possible to use a multi-stage structure for the rack gear to adjust the direction of rotation and achieve balanced movement.

Example The method shown in FIG. 2 is a two-axis method, and 8. This is a thrust/force neutralization method with a volume ratio of 3:1 and 9°.

This method differs from the method shown in Figure 1 in that it uses a double-axis cylinder (1), a cylinder for both reciprocating motion, and a forward/reverse pump for switching reciprocating motion, but the principle is the same.

It is also possible to use a mechanical cam valve instead of the solenoid valve.

Furthermore, even though it is called equal volume circulation, it is not strict; it is effective if the discharged fluid volume is slightly higher than the required fluid volume.

(1c) In this engine, when only the structure on the forward or backward side is attached to an existing machine, it is called a differential pressure device.

■) Additionally, the cylinder stroke can be changed by changing the diameter of the gear,
This is possible by changing the rotation speed, rotation angle, gear pitch, position of the force application point, etc.

Furthermore, changes in cylinder volume are also possible in 7, 8.9. , can be selected by maintaining the volume ratio.

In addition, it is possible to use a shaft attachment point, lever, crank, differential gear, etc. Furthermore, a differential method using a pulley, drum, etc., and a wire chain, etc. is also effective.

The liquids to be used should be those with low viscosity and low compressibility, such as water, oil, and chemical substances.

Furthermore, if a refrigerant liquid is used as the working fluid, this engine can also function as a refrigerator as it repeats the cycle of compression and release.

In addition, the arrangement of the cylinder and rack gear shaft is not straight,
It is also possible to create a compact structure by folding the 180u.

Qo The above is an explanation of the principle of motion and structure of the present invention.The greatest effect of the present invention is that the fluid It is in providing the prime mover.

Furthermore, this engine can increase the output in proportion to increasing the pressurization, cylinder stroke, pressure receiving area, etc.

In addition, the star-shaped arrangement centered on the output shaft and the parallel arrangement of many engines make it easy to manufacture high-output engines, making them suitable for ships, vehicles,
It is suitable as a propulsion engine for aircraft, etc., and is also effective as a drive source for lifts, refrigerators, man pressers, civil engineering construction machinery, etc.

Furthermore, it is the most suitable driving source for a generator, making it an important invention that contributes to solving energy problems.
