Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. An object of the present invention is to provide a power-saving differential fluid prime mover.

[0002]

[Prior Art] At present, there is no prime mover that operates with pressure as the main input, and there is no complete product.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide an input-saving fluid power engine in which the input from a pressure source pump is mainly composed of pressure and minimizes fluid inflow. The problem lies in the development of a structure that generates motion with pressure as the primary input.

[0004]

A propulsion and discharge cylinder is provided with a gear point of relative rotation of a differential gear moving on a rack surface as a point of application. By selecting the gear diameter and the direction of rotation, the thrust direction and the direction of movement of the discharge cylinder itself are opposed to each other, thereby dissipating power and causing imbalance of thrust in equal pressurization with the propulsion cylinder.

The most significant feature is that a circulating motion is generated between the cylinders due to the imbalance of thrust, and a fluid engine whose main input is pressurized pressure is established. Next, install a multi-stage pump of low pressure and high pressure or reduce the pressure of the fluid inside the cylinder.
An excellent feature is that the installation of an auxiliary cylinder for injection has made the system even more sophisticated and energy-saving.

[0006]

FIG. 2 shows an embodiment of the structure and principle of countermeasures against the thrust of two fluid cylinders with the gear as the point of application, which causes imbalance in thrust by equal pressurization and generates circulating motion. To do. 11 propulsion cylinders and 10 receiving pressure areas
0 square centimeters, travel 120 centimeters. Twelve discharge cylinders, 400 square centimeters of pressure receiving surface, and 30 centimeters of stroke. Each is set to an equal volume of 12 liters.

The diameter of 16 moving gears meshing with 15 fixed racks is about 20 cm. 17 is fixed on the same axis as 16
The diameter of the rotation transmitting gear is 30 cm. The diameter of the 18 rotation direction conversion gear meshing with 17 is 30 cm. The diameter of the opposing gear, which is fixed to the same shaft as 18, is 19 cm.

FIG. 2 shows the gear bearing stand 30 just before reaching the right end of the fixed rack. 8, the reversing pressurizing circuit is pressurized, and the cylinders 11 and 12 are pressurized equally.
Thrust is generated in the direction of. The thrust direction of the discharge cylinder 12 is counterclockwise as indicated by 23. The 16 gears are rotated clockwise through the gears of 14 rack shafts 19, 18 and 17 connected to the piston, and the 15 fixed racks are rotated. There is no movement because it tries to move the 30 shaft holders to the right indicated by 39 because it meshes with the surface, and because it tries to drive in the direction opposite to its own thrust.

Therefore, a thrust imbalance occurs between the 12 discharge cylinders and the 11 propulsion cylinders that do not generate output, and the movement of the piston and the internal fluid occurs. With the installation of the circulation circuit attached to the moving circulation pressurization circuit of the internal fluid, the relative movement of 11 and 12 becomes easy, and it moves in the direction of 39. Therefore, the eleventh propulsion cylinder retains the total thrust by the equal volume circulating flow from the twelve discharge cylinders which does not lose the output and does not become a resistance, and the propulsion which inputs only the pressurized pressure which does not require the inflow of fluid from the pump Exercise.

More specifically, the counterclockwise 1 of the 19 gears
In the rotation, I will move the cylinder cylinder 40 to the left and move the circumference of about 30 cm.
Subtraction by one rotation of 39 of the 16 gear shafts by about 60 cm of rightward movement eventually results in 12 piston rails 39.
30cm to the right. Therefore, 12
The volume of the internal fluid is compressed, resulting in an equal volume circulating flow of the 11 propulsion cylinders, and a uniform pressurized circulating motion that does not require the inflow of fluid from an external pump.

[0011] However, as a feature of the equal pressurized circulating motion, the motion can be continued by inputting only during pressurizing and during pressurizing. Press fitting is required. 10% capacity, the required amount of decompression. It can be said that 10% inflow, when frequent depressurization and pressurization is repeated, the power saving effect of the circulating motion of equal pressure input is reduced by half.

As a countermeasure against the problem, 10
Percentage pressure reduction is released to the auxiliary cylinder, and just before the next pressurization, alternate thrust is used to complete the return injection of the released pressure-reducing fluid into the main cylinder at low pressure. For example, the input from the pump at the time of start-up is possible with about 3%. It is also effective to use a low pressure and high pressure multi-stage pump or to use a variable pressure pump to reduce the input.

In the case of the embodiment shown in FIG. 2, the total volume of the cylinders 11 and 12 is 24 liters in total, so that it is one tenth, 2 and 4 liters. During exercise, the pressure of 2 or 4 liters of the next stroke must be completed within 1 second of the required decompression time at the forward terminal, backward terminal, etc. The working pressure is 50 atm, the input horsepower is assuming the use of 3 liters per second pump in consideration of the discharge capacity, and the hydraulic pump needs about 30 horsepower.

When the speed of the engine is 1 meter per second and the cycle of 1 second of motion, 1 second of pressure reduction and pressurization is repeated, the input consumption state occupying most of the output, The practicality of this will not hold. Therefore, in this embodiment of FIGS. 1 and 2, the auxiliary cylinders 32 and 33 are additionally provided, and when the forward end of FIG. 1 is stopped, the fluid required for decompression is discharged into the auxiliary cylinder 32.
If the reciprocating injection is performed during the reversing motion, the necessary input at the time of the next forward start-up is required. Only the pressurization of 0 and 3 liters is required, and the input equipment of the 4-horsepower pump becomes possible. To do.

[0015]

Embodiment The mechanism of the embodiment is various. First, the embodiment of FIGS. 1 and 2 will be described. Fig. 2 This is a linear reciprocating engine, which is on the verge of arriving at the right terminal at 39.
Fig. 1 shows the gear shaft holder of Fig. 30 just before reaching the left end. In FIG. 2, when the right terminal is reached, the reversing valve of 6 is set to OF, the auxiliary valve of 35 is opened, the electromagnetic clutch of 28 is set to OF, and the pressurized fluid of the circulation circuit of 10 is released to 33 auxiliary cylinders. The spring of fluid 38 is compressed and filled inside 33.

When it is full, turn on the electromagnetic clutch 38 and wait. In the forward pressurizing circuit of No. 7, since the injection from 32 was completed during the retreat as described in the item of operation, the forward valve of No. 5 was turned on at the same time when the pressure reduction of the circuit of No. 8 was completed. The circuit is pressurized and the pressure is increased instantaneously at the press-fit of 0 or 3 liters, and the forward movement to the left of 24 is started. Principle of motion As described in the item of action, 12 cylinder pistons that do not generate output are compressed in the direction of 24, and advance to the left by 11 cylinder thrust.

When the vehicle reaches the left-hand terminal, the position is detected by a limit switch or the like, the forward valve 5 is turned off, the auxiliary valve 34 is opened, the circuit 7 is depressurized, and the retraction valve 6 is turned on simultaneously with the completion of depressurization. It shifts to the rightward retreating motion by pressurizing the reversing pressurizing circuit of repetition 8. If you return to the right terminal after one second,
The exercise cycle is continued by switching to the 5 advance valve again.

Take out the output shaft 13 from the rack shaft,
5 and 26 one-way rotating clutch gears always transmit the same direction rotation to 27 rotation output shafts. The above is the description of the structure and operation principle of the embodiment. Exercise stroke of the embodiment is a repetition of 1 second release time and 1 second exercise time,
It is effective to add the mechanism of the embodiment as a method to eliminate the one-second release pause time loss.

Also, a manufacturing method using rollers, smooth shafts, etc. is possible, and it is also possible to change the cylinder volume, stroke, select the gear diameter, etc. The speed can be controlled by adjusting the flow rate of the circulation circuit. In addition, with the addition of a small pump, accumulator, dynamo, battery, etc.,
It can be used as an independent engine.
Also, the spring is used for the auxiliary cylinder,
In practice, the use of a pneumatic stabilizing valve is effective.

According to the principle of the structure of the differential circulating motion of the present invention, the efficiency is extremely large because the main input is the pressure of the fluid engine, and the input efficiency is about 10 times that of the conventional hydraulic engine.
Because it is more than double, it can be used for various purposes. Applications of differential fluid circulation engines include reciprocating engines such as presses, lifts, injection molding machines, etc., and propulsion engines for vehicles, ships, etc.
This is an important invention that contributes to energy conservation as a driving engine for a generator.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. An object of the present invention is to provide a fluid differential engine that moves with pressure as a main input.

[0002]

2. Description of the Related Art At the present time, advanced finished products of pressure input differential engines are not provided.

[0003]

[Problems to be solved by the invention] The problem of the differential pressure engine is how to efficiently reduce the reverse propulsion generated in the propulsion cylinder.

[0004]

In the method of reducing the reverse thrust generated in the discharge cylinder, a structure in which the movement stroke of the balancing cylinder is shortened and opposed by interposing a gear, a balance, a crank wheel and the like. First
It is a feature. The second feature of the input reduction mechanism at startup is the installation of a low-pressure or high-pressure two-stage pump, a variable pressure pump, and the provision of a ribbed cylinder that absorbs and injects depressurized fluid.

[0005]

[Function] It is extremely effective in reducing the reverse thrust, such as umbrella type, Y, T, L, V-shaped, etc. in a balanced arrangement. However, the problem is that the thrust changes abruptly according to the movement stroke. In the present invention, by using a gear, a balance, a crank wheel, or the like, the action stroke of the balance cylinder is shortened by the action of the balance due to the difference in the distance from the fulcrum to the point of application, or the deceleration action, etc., and the effective part of the stroke is reduced. It can be said that the basic structure of the differential pressure engine has been established by the selective use of only one.

In addition, since the engine is frequently started and stopped repeatedly, the input at the time of starting and the boosting must be completed instantaneously, the consumption capacity becomes enormous, and the effect of reducing the pressurized input of the engine is reduced. It becomes a problem that disappears. Therefore, by installing a two-stage pump, a variable pressure pump, etc., or by installing a ribbed cylinder that absorbs and injects the discharge fluid at the time of depressurization, etc., the two-stage pressurization of low pressure injection and high pressure pressurization saves The feature is that the input effect has been restored.

[0007]

The thrusts of the opposing cylinders in the T-shaped balance arrangement of 3, 14, and 15 are opposed by the gears 16 and 17 as the point of application, and 1
Reverse thrust 2 is neutralized. Therefore, 11
Thrust of the propulsion cylinder is generated, and 12 internal fluids 9
It was confirmed by experiments that the propulsion motion was continued by inputting only pressurization without the need for fluid inflow from the eleventh propulsion cylinder pump because the eleventh propulsion cylinder moved through the circulation circuit.

The pressure receiving area of the thirteen counter-arranged main cylinders is 400 square centimeters. The pressure receiving area of 12 discharge cylinders is 100 square centimeters. The diameter of 16 gears at 13 force points is 10 cm. The diameter of 17 gears with 12 force points is 40 cm.

Therefore, in one rotation of the gear, the stroke of the balancing main cylinder and the stroke of the discharge cylinder are reduced by a quarter, thereby realizing a neutral state of thrust. Therefore, only the effective portion of the balanced cylinder stroke can be used, reducing the effect of fluctuations in thrust.

At the beginning of startup, the forward valve 5 is turned ON,
When the forward pressurizing circuit 7 is pressurized, 11, 12, 13, 1
Cylinders 4 and 15 are equally pressurized at a low pressure of about 10 kilograms, and when each cylinder is filled with low-pressure fluid, turn on the high-pressure valve 4 to complete the pressurization. The direction of the thrust indicated by, but the balancing cylinder itself is the forward thrust.

[0011] The time required for completing the pressure rise is within one second,
The input at startup when the high pressure side pressurization is set to 50 kg is as follows. The amount of depressurized fluid discharge at the time of stoppage is one-tenth of the total cylinder volume. Each cylinder stroke is 120 centimeters and the three strokes of the balancing cylinder are shortened. The balancing main cylinder volume is 12 liters, the total of 14, 15 is 12 liters, and the total volume of 11, 12 is 24 liters. Liters, for a total of 48 liters.

[0012] One tenth of the total volume is about 5 liters. When 5 liters are input in 1 second, a pressurization of 50 kilograms requires about 40 horsepower. In the case of two-stage pressure, it is possible to apply 10 kilograms of pressure and 3 horsepower. Even when pressurizing at the time of switching to 50 kilograms, there is almost no inflow of fluid, so 3 horsepower of the same prime mover is sufficient.

From the above description, it is clear how effective two-stage pressurization is in saving labor. 20 if the boost is completed
Without the need for fluid inflow from the pump,
By the input of only pressurization, it moves in the forward movement direction indicated by 23 and the leftward movement speed 1 meter. When it reaches the 29 forward terminal, the position is detected by the limit switch etc.,
The valves 5 and 4 are set to OF, the retraction valve 6 is turned on when the pressure release is completed, and then the retraction movement is started when the high pressure valve 4 is turned on.

After returning to the 28 retracted position, the valves 6 and 4 are turned off, and the above procedure is repeated again to continue the reciprocating motion cycle. The output is transmitted to the output shaft of 27 through the one-way rotation clutch of output 26. This concludes the description of the principle and structure of the differential pressure rotary engine.

It is also possible to use a manufacturing method in which a balance, a crank wheel, etc. is used as the point of application of the piston. The gear diameter, cylinder stroke, and volume can be selected, and a gear moving method using a fixed rack can be manufactured. Speed control is possible by adjusting the flow rate of the circulation circuit. Also, a small pump,
With an accumulator, dynamo, battery, etc., it can be used as an independent engine. also,
It is also effective to use a relative arrangement method by installing multiple balancing cylinders, and it is also possible to use a balancing cylinder arrangement in a separate circuit to apply higher pressure.

In the method of reducing the reverse thrust generated in the discharge cylinder, the movement stroke of the balancing cylinder is shortened by interposing a gear, a balance, a roller, a crank wheel and the like as a reduction mechanism. The first feature is the opposing structure. Next, a low-pressure, high-pressure two-stage pump,

[Function] Mechanisms such as umbrella type, Y, T, L, V-shape, compound type, etc. of balanced arrangement, and equal pressurization of balanced arrangement itself,
Since a restoring thrust is generated at the equilibrium position of the piston shaft gathering point, it can be established as a motion-generating engine even with a balanced arrangement alone. However, the problem is that the thrust changes according to the movement stroke.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a linear reciprocating differential engine of the TY combined type arrangement is shown in FIG.
W, it shows the state of reaching the terminal in the left direction. With the principle of motion shown in FIG. 1, the thrust of the 12 discharge cylinders and the balancing cylinders of the TY composite type balancing arrangement of 13, 14, 15, 31, 32 increases the gears of 16, 17 by the equal pressurization of the circuit of 7. The thrust is countered as the point of impact and the thrust of the 12 cylinders is neutralized.

Accordingly, thrust of only the eleventh propulsion cylinder is generated, and the thrust of the eleventh propulsion cylinder-pump is generated because the thrust of only the eleventh propulsion cylinder is generated. No inflow of fluid is required, and the propulsion motion is continued by inputting only pressurization.

The pressure receiving area of the thirteen counter-arranged main cylinders is 300 cm 2. The pressure receiving area of 12 discharge cylinders is 100 square centimeters. The diameter of 16 gears at 13 force points is 10 cm. The diameter of 17 gears with 12 force points is 30 cm.

Therefore, in one rotation of the gear, the stroke of the balancing main cylinder and the stroke of the discharge cylinder are reduced to one third, and the internal volume of the cylinder is adjusted. Therefore, only the effective portion of the balanced cylinder stroke can be used, reducing the effect of fluctuations in thrust.

At the beginning of startup, the forward valve 5 is turned ON,
When the forward pressurizing circuit 7 is pressurized, 11, 12, 13, 1
Cylinders 4, 15, 31 and 32 are equally pressurized at a low pressure of about 10 kilograms, and when each cylinder is filled with low-pressure fluid, turn on the high-pressure valve 4 to complete the pressurization. The direction of thrust indicated by each cylinder 22 is generated in the forward direction of the balancing cylinder itself.

[0012] The time required for the completion of boosting is within one second,
The input at startup when the high pressure side pressurization is set to 50 kg is as follows. The amount of depressurized fluid discharge at the time of stoppage is one-tenth of the total cylinder volume. Therefore, it is necessary to perform a return injection at the time of startup. Propelling cylinder stroke is 100 cm and the volume is 10 liters. Discharge cylinder stroke is 33 cm, about 10 liters. The stroke of the balancing cylinder has been reduced to a total of 20 liters.

The total volume is 40 liters, which is 1/10 or 4 liters. When inputting 4 liters in one second, the pump input requires approximately 30 horsepower in the case of pressurization of 50 kilograms. In the case of two-stage pressure, it is possible to apply 10 kilograms of pressure and 3 horsepower. 50
Even when pressurizing at the time of switching to kilograms, there is almost no inflow of fluid, so three horsepower of the same prime mover is sufficient.

From the above description, it is clear how effective two-stage pressurization is in saving labor. 20 if the boost is completed
Without the need for fluid inflow from the pump,
By inputting only pressurization, the robot moves in the forward movement direction indicated by 23 and the leftward direction at 1 m / s. When it reaches 29 forward terminals, the position is detected by the limit switch and the like.
When the pressure release is completed, the reversing valve is turned ON, and when the high pressure valve is turned ON, the reversing motion starts.

After returning to the 28 retracted position, the valves 6 and 4 are turned off and the reciprocating motion cycle is continued by repeating the above procedure again. The output is transmitted to the output shaft of 27 through the one-way rotation clutch of output 26. The output is proportional to the pressure receiving area, pressure and speed of the propulsion cylinder. This concludes the description of the principle and structure of the differential pressure rotary engine.

Also, a manufacturing method using a balance, a roller, a crank wheel or the like as a point of application of the piston is possible. The gear diameter, cylinder stroke, and volume can be selected, and a gear moving method using a fixed rack can be manufactured. Speed control is possible by adjusting the flow rate of the circulation circuit.

In addition, it can be used as an independent engine by attaching a small pump, accumulator, dynamo, battery, etc. It is also effective to install multiple balancing cylinders, and it is also possible to use a different circuit for balancing cylinders and apply higher pressure.
In addition, parallel installation of this institution is also effective.

According to the present invention, the differential recirculating engine of the present invention uses the pressurized pressure as the main input, so that the input efficiency can be several times higher than that of the conventional hydraulic engine. This is an important invention that contributes to energy conservation and the environment as a driving engine for propulsion engines for vehicles, ships, etc., as well as reciprocating engines for aircraft and civil engineering machines.

A circulating cylinder is disposed such that the vicinity of both sides of a gear, a balance shaft, a roller, a crank, a pulley and the like is a point of application and a mutual thrust of a cylinder piston is opposed.
A fulcrum cylinder having a moving shaft center such as a gear, a roller, a crank, a pulley, etc. as a point of application is installed. The structure is such that the circulating cylinder moves relative to the fulcrum cylinder, and the cylinders are reciprocally moved by equal pressure of each cylinder to generate a motion that takes the pressurized pressure as the main input. Consisting of a differential pressure rotating engine.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. An object of the present invention is to provide a structure and a motion principle of a low-input circulating pressure engine.

[0002]

2. Description of the Related Art At present, in a fluid engine that moves with pressure as a main input, the number of cylinders used is four to one.
It requires zero installations and has a complicated structure, which has been a problem to be solved in the production of engines.

[0003]

[Problem to be solved by the invention] The problem lies in the development of a simple mechanism and a structure for accurate movement generation.

[0004]

Means for Solving the Problems According to the present invention, a three-cylinder arrangement has established a new motion mechanism with a simple structure that generates a propulsion motion at equal pressurization.

[0005]

The operation of the engine will be described with reference to FIG. The thrust is applied in the same direction to the left, with both sides of the twelve gears held on the idler shaft 15 as the point of force, and the circulating cylinders 10 and 11 are pressurized in the same left direction. This is the state of opposition to thrust because the thrust is pressurized.

The cylinders 10 and 11 have the same volume, and the pressure receiving area and the stroke are half the volume of each other. Therefore, when equal pressure is applied, the thrust difference at rest is 2 to 0, The difference between the above thrusts causes differential motion. However, the thrust difference is 1 to 0,5 because of the action of the speed increasing gear at the time of movement, and the thrust difference is 10: 5, and the theoretical output is 0,5. It is possible to arbitrarily select 13 gears.

Output shafts 16, 17, and 18 can be selected. The internal fluid of each cylinder at the time of forward movement, the relative motion of retracting the piston shaft of 10 in conjunction with the forward movement of the propulsion shaft, the internal fluid of 10 and the eleventh flow, 9
The volume of the internal fluid is reduced and the internal fluid circulation cylinder is added. Therefore, it does not require the inflow of fluid from the pump, and the forward motion is continued with a thrust difference of 1: 5 by inputting only pressure. Fluid motion with pressurized pressure as the main input.

The above is a description of the differential motion generation by the balance action based on the application of equal pressurization based on the principle of Pascal. When pressure is input, compared to the efficiency of a conventional fluid engine,
It has the characteristics of several tens of times, and provides the maximum effect as a reduced input fluid engine. The above is the description of the structure and the principle of motion that generate circulating motion with the main input of pressurized pressure. next,
The actual structure will be described with reference to the embodiment of FIG.

[0009]

[Embodiment] FIG. 1 shows a reciprocating engine, showing a state immediately before the start of the forward start position of the right terminal, and FIG. 2 shows a state reaching the forward end. First, drive the pump 2 and then turn on the advance valve 5 to pressurize the circuit 7 and the obliquely forward portions of the cylinders 9, 10 and 11 will be equally pressurized. A fulcrum is formed using the pressurized rack shaft 15 as a point of application, and the rack shafts 16 and 18
Since both sides of gear 2 are used as the point of application, the operation is the same as that of the balance.

Accordingly, the racks 15, 17, and 18 generate motion in the direction of each 27, and start the forward motion according to the principle described in the section of operation. During the movement, the differential gears of the thirteen move relative to the piston shafts of the pistons 10 and 11 due to the action of the differential gears, so that there is no need for the inflow of fluid from the pump due to the generation of a circulation of 10 to 11 times. And exercise. The output of the 19 propulsion shafts during motion is transmitted to the 26 output shafts as one-way rotation of 21 clutched gears.

When the vehicle reaches the forward end, the state shown in FIG. 2 is reached, the position is detected by a limit switch or the like, the valve 5 is turned off, and when the circuit 7 is depressurized, the valve 6 is turned on.
Equally pressurize circuit 8 and equalize the retraction side of cylinders 12 and 13. Therefore, according to the same principle as when the propulsion shaft of 19 is moving forward, it changes to the retreating motion shown in 29.

When returning to the retreat position, the reciprocating cycle is continued by repeating the above procedure by turning on the retreat valve 5 again. That's it for the outline of structure and continuity of movement.

As a feature of this engine, it is possible only by pressurizing during exercise, but fluid inflow is required as a pressure boost input at startup. I will explain the input at startup, input pressure,
It is proportional to volume and speed. The required volume for input when starting the engine and the volume required for fluid release required for decompression when the engine is stopped are the same. If the pressure receiving area of cylinders 10 and 11 is 100 square centimeters and the stroke is 1 meter, the volume is 10 liters.

Normally, one tenth of the total volume of cylinder pressurization at start-up is the release amount. Therefore, at startup, an instantaneous input of a fluid volume that is one-tenth of the total volume of the cylinder is required. Therefore, the pressurized part of this engine and the 9 due to circulating flow are about 13 liters in total. Therefore, about 1,3 liters per second is required at startup.

1, 3 liters of pump input per second, 50
Approximately 15 horsepower is required for pressurizing the air pressure.Therefore, it is a performance that can be used at present with a press with a long cycle time, etc. It is not enough to save input. Therefore, when used as a prime mover, it is effective to add a two-stage input method.

A two-stage pressurizing method is used as a power-saving method at the time of starting. First, after a fluid is filled in the cylinder at a low pressure of about 10 atm, a high-pressure valve is turned on to switch the pressurization to 50 atm. With a stage pressurization method, input can be made with both low-pressure and high-pressure pumps at about 3 horsepower. Therefore, it is effective to install a low-pressure or high-pressure two-stage pump or a variable pressure pump as the starting method.

A conventional fluid engine requires about 100 horsepower to move a 10 liter cylinder at 1 meter per second at 50 atm. Efficiency of this engine that enables 100 horsepower at 3 horsepower It can be said that a very high output efficiency is expected even when comparing the engine and the internal combustion engine that exist today. Also, in order to eliminate the one-second release pause time loss in the exercise process of the embodiment, it is effective to use two or more sets of the embodiment mechanisms in parallel in an alternate activation system.

Further, the cylinder for the fulcrum is connected in series,
With this installation, it is possible to use four cylinders in combination with two relative circulation cylinders. It is also possible to use balances, rollers, cranks, pulleys, etc. for differential gears as well as gears, cranks, rollers and pulleys.

It is also possible to use differential gears and reduction gears.
The speed can be controlled by the flow control valve in the circulation circuit.
The addition of a small pump, accumulator, dynamo, battery, etc. makes it possible to use it as an independent engine.

[Effect of the Invention] Since the main input is the circulating pressure engine of the present invention, the input efficiency is extremely superior to that of the conventional engine, so that it can be used in various applications. Press, lift, injection molding machine,
This is an important invention that contributes to energy conservation as a reciprocating engine such as civil engineering machinery, a propulsion engine for vehicles and ships, and a driving motor for a generator.
