Abstract

PROBLEM TO BE SOLVED: To bring about an energy-saving effect by generating moving motion of a cylinder inside fluid by rotation of an equal pressure pump in arrangement to enable equal pressure of suction side and delivery side pressures of the pump. SOLUTION: A motor 9 is rotated in the delivery direction 21, and an inside fluid is moved, and an outer cylinder of a cylinder 14 is moved in the advancing direction 29. Cylinders 13 and 15 are moved by fluid in the rotational direction of a pump 10, and a shaft 18 is moved in the retreating direction 30. When a propelling shaft 17 reaches an advancing position, it is detected by a limit switch, and the pump 10 is reversely rotated in the delivery direction 22, and the propelling shaft 17 is retreated. Output of the propelling shafts 17 and 18 at moving time is transmitted to an output shaft 27 as unidirectional rotation of a gear 26 having a clutch only at advancing time. An engine is formed as a closed circuit engine, and pressurizing pressure of fluid is used as main input. Therefore, output efficiency is enhanced, and energy can be saved.

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 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 operating with pressure as a main input, the number of cylinders used is reduced from six to one.
The installation of zero or the like was necessary, and was a problem to be solved in the production of an engine.

[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, the principle of movement is established by a simple structure that generates a propulsion movement at equal pressurization by arranging at least two cylinders.

[0005]

[Action] The generation of motion of this engine will be described with reference to FIGS. FIG. 2 is a reciprocating engine using three cylinders according to the second embodiment. FIG. 2 shows the posture at the time of activation in the forward direction shown in FIG. 30, and FIG. 3 shows the posture arrived at the forward terminal. The cylinders 12, 13, and 35 have the same volume and are pressurized with the same pressure. As shown by the thrust direction 22, the thrust is opposed to 2: 1. In the pressure opposing state shown in FIG. 2, as shown by 32 sectors,
It moves in a fan shape with the power of human hand.

[0006] There are 21 shaft attachment points, which are the fulcrum points of the 16 balances, which are the points of opposition to the thrust.
It depends on the neutralization of the thrust circuit of 2,13, the idling action of the shaft using bearings, etc., and the installation effect of the circulating circuit of 9. However, when there is no installation of 15 differential gears in a state where the combined thrust of 35, 12 and 13 is opposed, 16
Since the balance shaft does not move in a fan shape and the shafts 12 and 13 move forward at the same time, the inflow of fluid from the pump occurs and the circulating motion does not occur.

Therefore, by providing 15 differential gears and retreating the 19 piston shafts in conjunction with the forward movement of the 24 propulsion shafts, the internal fluid 13 and the second 12 are circulated. Therefore, the inflow of fluid from the pump is not required, and 1
The thrust is maintained at 2,13, and the forward motion is continued by the one-to-two thrust difference. Fluid motion with pressurized pressure as the main input. Another characteristic of this exercise is that the balance operation of 16 cannot be achieved without the load of 35 counter cylinders forming 21 balance fulcrums. Therefore, it is effective to install 37 electromagnetic brakes as in the first embodiment.

[0008] The forward movement of the 24 propulsion shafts compresses the 35 cylinders and retreats the internal fluid, filling the 34 accumulators. Fig. 3
In this state, the circuit 7 is depressurized to generate a retreating motion by the output of the accumulator.

As described above, according to the second embodiment, both sides of the balance action are used as the point of application of the circulating cylinder to counter thrust.
This is an explanation of the structure and the principle of motion, in which a load is applied to the fulcrum of the balance function with an idling shaft and a relative movement is made to the circulating cylinder by the addition of gears, etc., and a circulating motion with the applied pressure as the main input is generated. Although the above-mentioned motion generation phenomenon has been confirmed by experiments, it can be said that this is the discovery of a new principle of motion in fluid mechanics. Next, the actual structure will be described with reference to the first embodiment of FIG.

[0010]

[Embodiment] The first embodiment of FIG. 1 is characterized in that the balance shaft is replaced with a gear, and that the backward movement system is a circulation cylinder propulsion system which is the same as the forward movement system. The state at the time of startup in the forward direction of No. 30 is shown. First, drive the pump 2 and then turn on the advance valve 5 to pressurize the circuit 7 and the hatched forward portion of the cylinders 12 and 13 will have equal pressure. Since both sides of the gears of the rack shaft 36 of the pressurized 18 and 19 are used as the point of impact, the operation is the same as that of the balance.

Further, when the 24 propulsion shafts mounted on the idler shafts of the gears are unloaded, 3
Holds the balance action of gear 6 Next, due to the action of the 15 differential gears, relative motions of the piston shafts of 12 and 13 occur, and due to the generation of a circulating flow, the motion becomes the main input with the pressurized pressure. The output of the 24 propulsion shafts during movement is transmitted to the 27 output shafts as one-way rotation of 26 clutched gears.

When reaching the forward end of 29, the position is detected by a limit switch or the like, the valve of 5 is turned off, and when the circuit of 7 is depressurized, the valve of 6 is turned on and the circuit of 8 is pressurized at equal pressure. Equally press the retraction side of cylinders 11 and 14. Therefore, it changes to the retreating motion in the direction indicated by the 24 propulsion shafts 31.

After returning to the 28 retreat position, the reciprocating cycle is continued by repeating the above procedure by turning on the retreat valve 5 again. This is an overview of the structure and continuity of movement. Next, we will set the dimensions of the embodiment and explain the input / output problems.

The allowable stroke of each cylinder is 1 meter. The pressure receiving area of each cylinder is 100 square centimeters. The output of this engine is proportional to the pressure, the pressure receiving area, and the speed of circulation, and inversely proportional to the circulation resistance.

When the pressurizing pressure is set to 50KG and the piping cross-sectional area of the circulating circuit of No. 9 is set to 20 square centimeters, the hydraulic fluid speed can be 10 meters per second. However,
Assuming that the required filling time for a cylinder capacity of 10 liters is 0 or 5 seconds, the cylinder piston speed is 2 meters per second.

Therefore, the thrust of the propulsion cylinder is about 50 KG.
If you multiply the value obtained by multiplying the meter by 100 square centimeters per second and multiply by 2, you get 10,000KG meter second. However, because the effective thrust is one half, it is the output of 5000KG meter second.

The input will be explained. It is proportional to the input pressure, volume and speed. The required input of the engine is proportional to the amount of depressurized fluid released when the engine is stopped. Usually, one tenth of the total volume of cylinder pressurization at startup is the release volume. 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, 12, 132, is 10 liters in total. Therefore, about 1 liter per second is required at startup.

One liter of pump input per second requires about 15 horsepower. Therefore, although it is a performance that can be used at the present time with a press with a long cycle time, etc. in the contents more than this engine, it is not enough to reduce the input when used as a prime mover that frequently stops. Therefore, when used as a prime mover, it is effective to add a two-stage input method.

A two-stage pressurization method is used as a power-saving method at the time of starting. A two-stage pressurization method in which the high-pressure valve is turned on to switch the pressurization to 50 KG at the moment when the fluid is filled inside the cylinder at a low pressure of about 10 KG. With a pressurized system, 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, and it is also possible to attach an auxiliary cylinder dedicated to discharging and injecting depressurized fluid. A description of the exercise.

The input and output calculations are all theoretical values.
Although the loss has not been calculated, it can be said that even if the engine including today's prime mover and internal combustion engine is compared, it is a prime mover engine that is expected to have extremely high power efficiency. In addition, in order to eliminate the 1-second release pause time loss in the exercise process of the embodiment, it is effective to use two sets of the embodiment mechanism and alternate start-up system.

In the embodiment shown in FIG. 1, it is possible to omit the cylinders 11 and 14 and to use a reciprocating system using only the cylinders 12 and 13. It is also possible to use four propulsion and discharge cylinders. It is possible to use a balance, roller, crank, pulley, etc. for differential 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.

The circulating pressure device of the present invention has a very high input efficiency as compared with a conventional prime mover because the main input is the external pressure, so that it can be used in various applications. Press, lift, injection shaping 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.

[Action] The generation of motion of this engine will be described with reference to FIGS. FIG. 2 is a reciprocating engine using three cylinders according to the second embodiment. FIG. 2 shows the posture at the time of activation in the forward direction shown in FIG. 30, and FIG. 3 shows the posture arrived at the forward terminal. The cylinders 12, 13, and 35 have the same volume and are pressurized with the same pressure. As shown by the thrust direction 22, the thrust is opposed to 2: 1. In the pressure opposing state shown in FIG. 2, as shown by 32 sectors,
It moves in a fan shape with the power of human hand.

[0006] There are 21 shaft attachment points, which are the fulcrum points of the 16 balances, which are the points of opposition to the thrust.
It depends on the neutralization of the thrust circuit of 2,13, the idling action of the shaft using bearings, etc., and the installation effect of the circulating circuit of 9. However, when there is no installation of 15 differential gears in a state where the combined thrust of 35, 12 and 13 is opposed, 16
Since the balance shaft does not move in a fan shape and the shafts 12 and 13 move forward at the same time, the inflow of fluid from the pump occurs and the circulating motion does not occur.

Therefore, 15 differential gears are attached, and the internal fluid 13 and 12 are circulated by the relative motion of retracting the 19 piston shaft in conjunction with the forward motion of the 24 propulsion shafts. The load of relative motion is very small. Therefore,
It does not require the inflow of fluid from the pump, keeps the thrust of 12, 13 and continues the forward movement with a 1 to 2 thrust difference. Fluid motion with pressurized pressure as the main input. or,
It is also a feature of this exercise that the balance action of 16 cannot be realized without the load of 35 counter cylinders forming 21 balance fulcrums. Therefore, it is effective to install 37 electromagnetic brakes as in the first embodiment. The resistance action of the spring is also effective.

The thirty-four cylinders are compressed by the forward movement of the thrust shafts in the direction of thirty-five, and the inner fluid is retreated, filling the thirty-four accumulators. When it reaches the forward end and reaches the state shown in Fig. 3, it reduces the pressure in the circuit 7 and generates a retreating motion by the output of the accumulator.

As described above, according to the second embodiment, both sides of the balance action are used as the point of application of the circulating cylinder to counter thrust.
Description of the structure and the principle of motion, in which a load is applied to the fulcrum of the balance action with an idler shaft and a relative motion is made to the circulating cylinder by the addition of a differential gear, etc., and a circulating motion with the pressurized pressure as the main input is generated. is. The phenomenon of the propulsion motion caused by applying a load to the propulsion shaft has been confirmed through experiments, but this is a discovery of a new principle of motion in fluid mechanics.

First, drive the pump 2 and then turn on the advance valve 5 to pressurize the circuit 7 and the hatched forward portion of the cylinders 12 and 13 will have equal pressure. Pressurized, 18, 1
Since both sides of the gear of rack shaft 36 of No. 9 are used as the point of impact, the operation is the same as that of the balance.

Further, when the 24 propulsion shafts mounted on the idler shafts of the gears are unloaded, 3
Holds the balance action of gear 6 Next, due to the action of the 15 differential gears, relative motions of the piston shafts of 12 and 13 occur, and a circulating flow occurs, so that the motion is applied with the pressurized pressure as the main input. The output of the 24 propulsion shafts during movement is transmitted to the 27 output shafts as one-way rotation of 26 clutched gears.

When reaching the forward end of 29, the position is detected by a limit switch or the like, the valve of 5 is turned off, and when the circuit of 7 is depressurized, the valve of 6 is turned on and the circuit of 8 is pressurized at equal pressure. Equally press the retraction side of cylinders 11 and 14. Therefore, it changes to the retreating motion in the direction indicated by the 24 propulsion shafts 31.

After returning to the 28 retreat position, the reciprocating cycle is continued by repeating the above procedure by turning on the retreat valve 5 again. This is an overview of the structure and continuity of movement. Next, we will set the dimensions of the embodiment and explain the input / output problems.

The allowable stroke of each cylinder is 1 meter. The pressure receiving area of each cylinder is 100 square centimeters. The output of this engine is proportional to the pressure, the pressure receiving area, and the speed of circulation, and inversely proportional to the circulation resistance.

When the pressurizing pressure is set to 50KG and the piping cross-sectional area of the circulating circuit of No. 9 is set to 20 square centimeters, the hydraulic fluid speed can be 10 meters per second. Therefore,
Assuming that the required filling time for a cylinder capacity of 10 liters is 0 or 5 seconds, the cylinder piston speed is 2 meters per second.

Therefore, the thrust of the propulsion cylinder is about 50 KG.
If you multiply the value obtained by multiplying the meter by 100 square centimeters per second and multiply by 2, you get 10,000KG meter second. However, because the effective thrust is one half, it is the output of 5000KG meter second.

The input will be explained. It is proportional to the input pressure, volume and speed. The required amount of input to the engine is proportional to the amount of fluid discharge required for decompression when the engine is stopped. Usually, one tenth of the total volume of cylinder pressurization at startup is the release volume. Therefore, at the time of startup,
Requires instantaneous input of 1/0 fluid volume. Therefore, the pressurized part of this engine, 12, 13 is 10 liters in total. Therefore, about 1 liter per second is required at startup.

If the pressure system is used, both low-pressure and high-pressure pumps can input at about 3 horsepower. Therefore, it is effective to install a low-pressure, high-pressure two-stage pump or a variable-pressure pump as the starting method, and it is also possible to attach an auxiliary cylinder dedicated to discharging and injecting depressurized fluid.

[0002]

2. Description of the Related Art At present, in a fluid engine operating with pressure as a main input, the number of cylinders used is six 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 In the present invention, a new principle of movement is established by a simple structure in which a propulsion movement is generated with equal pressurization by arranging at least two cylinders.

[0005]

The operation of the engine will be described with reference to FIG. 2 and FIG.
An example will be used for explanation. FIG. 2 is a reciprocating engine using three cylinders according to the second embodiment. FIG. 2 shows the posture at the time of activation in the forward direction shown in FIG. 30, and FIG. 3 shows the posture arrived at the forward terminal. Cylinders 12 and 13 have the same volume, which is half the volume of 35 and 35. When the cylinders are pressurized with the same pressure, the thrust direction becomes as shown in FIG.
13. Due to the action of the balance, the output becomes one in total, 2 to 1
Of thrust. Therefore, in the forward state in the 30 direction, as shown by the 32 sector, it moves in the 16 balance axis sector.

[0006] This is a mechanism that does not relate to forward movement due to the idling action of the shaft using bearings, etc. Therefore, 3
In the state of opposition of thrusts of 5, 12 and 13, when 15 differential gears are not installed, 16 balance shafts and fan-shaped movement are not performed, and 12 and 13 shafts are simultaneously advanced. Fluid flow occurs, and the circulating motion is not established.

Therefore, 15 differential gears are attached, and the internal fluid 13 and 12 are circulated by the relative motion of retracting the 19 piston shaft in conjunction with the forward motion of the 24 propulsion shafts. The load of relative motion is very small. Therefore,
It does not require the inflow of fluid from the pump, keeps the thrust of 12, 13 and continues the forward movement with a 1 to 2 thrust difference. Fluid motion with pressurized pressure as the main input.

[0008] Another characteristic of the present movement is that the balance operation of 16 cannot be achieved unless there is a load of 35 counter cylinders forming 21 balance fulcrums. Therefore, when there is no load, it is effective to install 14 electromagnetic brakes as in the first embodiment of FIG. The resistance action of the spring is also effective.

The forward movement of the 24 propulsion shafts in the direction of 30 compresses the 35 cylinders and retreats the internal fluid while filling the 34 accumulators. When it reaches the forward end and reaches the state shown in Fig. 3, it reduces the pressure in the circuit 7 and generates a retreating motion by the output of the accumulator.

As described above, according to the second embodiment, both sides of the balance action are used as the point of application of the circulating cylinder to make the thrust counteract.
Description of the structure and the principle of motion, in which a load is applied to the fulcrum of the balance action with an idler shaft and a relative motion is made to the circulating cylinder by the addition of a differential gear, etc., and a circulating motion with the pressurized pressure as the main input is generated. is. The phenomenon of circulating propulsion motion caused by applying a load to the balance fulcrum of the propulsion shaft has been confirmed by experiments. It is a discovery of a new principle of motion in fluid mechanics. Next, the actual structure will be described with reference to the first embodiment of FIG.

[Embodiment] The first embodiment shown in FIG. 1 is characterized in that the balance shaft is replaced by a gear, and that the backward movement system is a propulsion system using the same circulating cylinder thrust as the forward movement system. Fig. 1 shows the start-up state of the forward direction shown in Fig. 30. First, drive the pump 2 and then turn on the advance valve 5 to pressurize the circuit 7 and the hatched forward portion of the cylinders 12 and 13 will have equal pressure. Pressurized,
Since both sides of the gears of the rack shafts 36 of 18 and 19 are used as the point of impact, the operation is the same as that of the balance.

Further, when 24 propulsion shafts mounted on the idler shafts of the gears have no load, 14 propulsion electromagnetic brake loads cause 1 propulsion shaft.
It keeps the function of 1 idle gear balance. During exercise, 15
Due to the action of the differential gear, relative motion between the piston shafts of the pistons 12 and 13 is generated, and the main input is the pressurized pressure, which does not require the inflow of fluid from the pump due to the generation of circulating flow. The output of the 24 propulsion shafts during movement is transmitted to the 27 output shafts as one-way rotation of 26 clutched gears.

When reaching the forward end of 29, the position is detected by a limit switch or the like, the valve of 5 is turned off, and when the circuit of 7 is depressurized, the valve of 6 is turned on and the circuit of 8 is evenly pressurized. Equally pressurize the retraction side of cylinders 12, 12 and 13.
Therefore, it changes to the retreating motion in the direction indicated by the 24 propulsion shafts 31.

After returning to the 28 retreat position, the reciprocating cycle is continued by repeating the above procedure by turning on the retreat valve 5 again. This is an overview of the structure and continuity of movement. Next, we will set the dimensions of the embodiment and explain the input / output problems.

The allowable stroke of each of the cylinders 12 and 13 is 1
It is a meter. The pressure receiving area of each cylinder is 100 square centimeters. The output of this engine is proportional to the pressure, the pressure receiving area, and the speed of circulation, and inversely proportional to the circulation resistance.

When the pressurizing pressure is set to 50KG and the cross-sectional area of the piping of the circuit 9 is 20 square centimeters, the hydraulic fluid speed can be 10 meters per second. Therefore,
Assuming that the required filling time for a cylinder capacity of 10 liters is 0 or 5 seconds, the cylinder piston speed is 2 meters per second.

Therefore, the thrust of the propulsion cylinder is about 50 KG.
If you multiply the value obtained by multiplying the meter by 100 square centimeters per second and multiply by 2, you get 10,000KG meter second. However, because the effective thrust is one half, it is the output of 5000KG meter second.

The input will be explained. The input is proportional to pressure, volume and speed. The required amount of input to the engine is proportional to the amount of fluid discharge required for decompression when the engine is stopped. Usually, one tenth of the total volume of cylinder pressurization at startup is the release volume. Therefore, at the time of startup,
Requires instantaneous input of 1/0 fluid volume. Therefore, the pressurized part of this engine, 12, 13 is 10 liters in total. Therefore, about 1 liter per second is required at startup.

One liter of pump input per second requires about 15 horsepower. Therefore, although it is a performance that can be used in the present situation with a long cycle time breath etc. in the contents more than this engine, it is not enough to reduce the input when used as a prime mover that frequently stops. Therefore, when used as a prime mover, it is effective to add a two-stage input method.

A two-stage pressurizing system is referred to as a power-saving method at the time of starting, in which a cylinder is first filled with a fluid at a low pressure of about 10 KG, and then a high-pressure valve is turned on to switch the pressurization to 50 KG.

Patent application title: Fluid engine using the principle of circulating motion of balance action

[Claims]

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 acting as a balance acts as an impact point, and a mutual thrust of a cylinder piston opposes. A load is applied to the shaft serving as the fulcrum of the balance action to counter the thrust of the circulation cylinder. A mechanism for causing the circulation cylinder to make a relative movement via a balance, a gear, a roller, a crank, a pulley, or the like in conjunction with the movement of the fulcrum shaft.
A fluid engine that uses the principle of the balance-driven circulating motion, in which circulating between the cylinders is generated mainly by the equal pressurization of two cylinders, and a motion whose main input is the pressurized pressure is generated.

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]

According to the present invention, two cylinders are arranged in parallel, and a fulcrum is moved forward by a relative motion by a balance action to generate a circulating propulsion motion at equal pressure. It is in the point.

[0005]

As shown in the second embodiment of FIG. 2, by applying pressure to the circuit 7 as shown in the second embodiment of FIG.
The thrust of the circulating cylinder of the same
The fulcrum counter cylinder for the fulcrum. The thrust is in the opposite state because the right-hand thrust is applied with the idle shaft of the roller 21 as the point of impact.

Cylinders 12 and 13 have the same volume and 35 cylinders have a pressure receiving area of one half. Therefore, when equal pressure is applied, the thrust difference at rest is 2 to 0.5. The difference between the above thrusts causes differential motion. However, the thrust difference is 1 to 0.5 due to the action of the speed-up gear at the time of movement and the reciprocating cylinder is 13 retracted due to the action of the speed increasing gear, and the difference between 0 and 5 is the theoretical output. In addition, 1
A gear ratio of 2 times that of gear 5 is appropriate.

Output shafts 18, 19 and 24 can be selected. The internal fluid of the circulation cylinder at the time of forward movement, the relative movement of the piston shaft of 13 retreats in conjunction with the forward movement of the propulsion shaft, and the internal fluid of 13 and 12 circulates,
The volume of 35 is reduced and the internal fluid is transferred to the accumulator. Therefore, there is no need for fluid inflow from each cylinder 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.

FIG. 2 shows a state at the time of start-up, and FIG. 3 shows a state where it reaches the forward end. If you release the pressurization of 7, it will retreat by the discharge of the fluid of the accumulator. The above is the explanation of the principle of the generation of circulating motion by the balance action by the application of equal pressure to the principle of Pascal. When pressure is input, it has the characteristic that it is several tens of times higher than the input efficiency of the conventional fluid engine. Therefore, it provides the maximum effect as a reduced input fluid engine. This is one example of 35 load cylinders, and the output form can be arbitrarily selected. Next, the actual structure will be described with reference to the first 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. First, drive the pump 2 and then turn on the advance valve 5 to pressurize the circuit 7 and the hatched forward portion of the cylinders 12 and 13 will have equal pressure. Since both sides of the gears of the pressurized rack shafts 11 and 18 are used as the point of application and the output shaft is formed with the idle shaft 21 as a fulcrum, the operation is the same as that of the gear balance.

As a function of the balance, in the case of the same pressure, it does not move in a balanced manner, but because of the intervening of the 15 speed increasing differential gears, the 19 shafts move backward and the 18 and 24 shafts move forward. You. During the movement, the piston shaft moves relative to the piston shafts 18 and 19, and it generates a circulating flow of 13 to 12 and does not require the inflow of fluid from the pump. The output of this engine is a 1 to 0 differential output because there is no counter cylinder. 24 during exercise
The output of the propulsion shaft is transmitted to the 26 output shafts as a unidirectional 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, the 24 propulsion axes change to retreating motion by the same principle as when moving forward.

When returning to the retreat position, the reciprocating cycle is continued by repeating the above procedure by turning on the retreat valve 5 again. This concludes the description of the structure and movement of the first embodiment.

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 12 and 13 is 100 square centimeters and the stroke is 1 meter, the volume is about 10 liters.

Normally, one tenth of the total volume of cylinder depressurization during stoppage 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, about 1 liter per second is required at startup.

A pump input of 1 liter per second requires about 20 horsepower for pressurization of 50 atm. Therefore, it is a performance that can be used at present with a press with a long cycle time in the contents more than this engine. However, when used as a prime mover that frequently starts and stops, it is not enough to reduce the 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 step-pressurizing method, input is possible with both low-pressure and high-pressure pumps at about 5 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.

In a conventional fluid engine, at a pressure of 50 atm, a stroke of 1 meter and a 10-liter cylinder moving at 1 meter per second require about 100 horsepower. The efficiency of this engine, which enables 100 horsepower at 5 horsepower, can be said to provide a prime mover that can be expected to have extremely high output efficiency, even when comparing modern engines and internal combustion engines. 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.

It is also possible to use two cylinders for the fulcrum, which are opposed to each other in series, and use two cylinders in addition to the two relative circulation cylinders. It is also possible to use gears, cranks, rollers, pulleys, etc. as the balance action method. Balances, rollers, cranks, pulleys, etc. can also be used for differential 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 circulating pressure engine of the present invention is mainly used as the input pressure, 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.

[Claims]

A thrust force of a pressure booster or a plurality of cylinders such as a pressure booster is counteracted by interposing a balance shaft, a gear, a roller, a pulley, a relative movement cylinder, or the like which acts as a balance. Further, the thrust between the boosters is generated in the non-blocking circuit side by setting a series blocking circuit and a parallel blocking circuit. A fluid engine that uses the principle of the circulating motion of the balance action, in which a circuit between the pressure intensifiers is generated by alternately pressurizing the forward and reverse circuits, and the pressurized pressure is the main input.

[0001]

DETAILED DESCRIPTION OF THE INVENTION

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-power input circulation engine.

[0002]

2. Description of the Related Art Conventionally, in a recirculating fluid engine that moves by using pressure as a main input, there is a balanced recirculating engine of a Y-shape, an arrow shape, etc., but the problem of short effective motion stroke is solved. Had to be a challenge.

[0003]

[Problems to be solved by the invention] The problem of the structure development is to provide the original linear motion structure of the cylinder, to completely extend the effective stroke of the cylinder, and to improve the output efficiency.

[0004]

SUMMARY OF THE INVENTION In the present invention, several types of circulating pressurizing circuits for preventing thrust are developed by using a structure in which the circulating motion is generated by opposing the thrusts of a plurality of intensifiers via a balance action. It is characterized by the point at which exercise output is generated.

[0005]

[Action] Fig. 1 shows a state where the terminal has reached the retreat terminal. As shown in FIG. 1, the structure of the engine is such that the boosters having the parallel arrangement of 14, 15 and the parallel arrangement of 16, 17 are
And a series circuit of 15 and 17, and the mutual thrust is a counter-arrangement mechanism via 29 balance gears. At the beginning,
The primary side of the four intensifiers is equally pressurized by the normal pressure circuit of 32, and then the secondary sides of 14, 16 are equally pressurized by the normal pressure circuit of 12 to prevent the series thrust. In addition, it features a structure that generates a propulsion motion on the non-pressurized side by alternately pressurizing the 7 and 8 parallel blocking pressurizing circuits.

[0006] There are various setting methods for the equal volume circulation circuit. In short, of the four cylinder thrusts, three propulsion
Motion generation is prevented by pressurizing the circuits 2 and 7 or 8, and only one thrust is generated. A thrust blocking circuit is used as a pressure circulation circuit. The generation of thrust of the equal pressure circuit
This is an application of the theory of Pascal's principle: the pressure applied to one point of the container, and the same pressure on all inner surfaces of the container. When the cylinders of the intensifier have the same volume, the gradient of the thrust is set, and they are connected by a circulating circuit, and when equal pressure is applied, an equal volume circulating flow of the internal fluid is generated, and the inflow of fluid from the pump is reduced. Fluid motion is generated by inputting only unnecessary pressurization.

[0007] If motion is generated only by pressurized input, labor savings of several tens of times can be achieved as compared with the efficiency of a conventional fluid engine. Therefore, even if the primary side volume of the intensifier of the embodiment is set to 20 liters and the secondary side volume is set to 10 liters,
Since one pump input is used as the main input, both can be operated at about 1 horsepower. The above explanation is the principle of circulating motion generation, and the input saving effect is very clear. The structure and exercise of this engine will be explained with reference to Figs.

[0008]

1 and 2, a reciprocating engine having a structure in which the balance action of 29 gears is used as an intervening mechanism, the thrusts of two intensifiers arranged in parallel are opposed to each other, and the thrust is further installed in series. is. Fig. 1 shows the state of the position where the terminal has reached the backward direction terminal. Fig. 2 shows the state where it has reached the forward end. This will be explained with reference to FIG.
If the normal pressure circuit of No.2 is pressurized, the primary side of the booster of No.14,15,16,17 is pressurized.Thrust is not generated because the thrust is balanced.

Next, if the normal pressure valve 11 is pressurized and the circuit 12 is pressurized, the secondary sides 14 and 16 are pressurized to prevent thrust. Further, when the reversing valve 6 is turned on, thrust of 17 is prevented by 8 circuits, so only thrust of 15 is generated, continuous reversing movement of 30 and reaches the retreat end shown in Fig. 1. When it reaches the retreat terminal, it is detected by the limit switch etc., the valve of 6 is turned on, and the forward valve of 5 is turned on.
If set to, it will be a forward movement to the left.

At the time of forward movement, the thrust of 15 is blocked by the pressurization of the circuit of 7, so that the thrust of 17 is generated.
Because it moves forward while being filled by the circulation of the internal fluid of 6, it does not require the inflow of fluid from the pump, and it is a movement with the main input of the pressurized pressure. Output of 18 propulsion axes during exercise,
It is transmitted to the output shaft of 27 as one-way rotation of gear with 26 clutch. When reaching the forward end, the state shown in FIG. 2 is reached, and the position is detected by a limit switch or the like,
When 5 is turned off again and 6 is turned on, it moves to the backward movement.

The reciprocating motion cycle is continued by repeating the above procedure. However, when starting the pressurizing valve,
Requires a fluid flow of 10% of the pressurized volume. The reason is that the amount of required fluid to be decompressed at the time of stop is 10%. In addition, filling within 1 second is required. In this embodiment, it is 10 liters. Excessive consumption input. Therefore, it is necessary to use a low pressure and high pressure two pump input, a variable pressure pump input, or a starting method such as a residual pressure method.

The structure of the embodiment and the principle of movement have been described above. As described above, since the main input is the pressurized pressure of the fluid of the present engine, it can be said that the provision of a prime mover which is several times as large as the output efficiency of the conventional fluid engine, and is expected to have extremely high output efficiency. You.

Further, in the exercise process of the embodiment, as a method of eliminating a pause time loss at the time of switching, it is effective to use an alternate starting system in parallel with two or more sets of the mechanism of the embodiment.
Also, instead of the balance interposition method, whether it is a roller and a smooth moving surface,
It is possible to use a manufacturing method in which a gear and a rack shaft, a pulley and a wire or a relative motion cylinder are interposed.

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. It is also possible to use the one-way motion of this engine and use it in combination with other machines.

In addition, a manufacturing method using large and small cylinders in place of the pressure intensifier is possible, and a mixed method of the pressure intensifier and the cylinder is also possible. In addition, a reversible pump can be used instead of the switching valve. Also, change the booster ratio of the booster,
The volume can be changed. In addition, there are several types of change in the selection of the normal pressure circuit and the circulation pressurization circuit.
In addition, a production method using three intensifiers is also possible.

[Effect of the Invention] Since the circulating pressure engine of the present invention is mainly used as the input pressure, 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 such as a vehicle and a ship, and a driving motor such as a generator and a refrigerator.

[Claims]

(1) A thrust force of a propulsion cylinder and a discharge cylinder is countered with a thrust force of a propulsion cylinder and a discharge cylinder by interposing a balance shaft, a gear, a roller, a pulley, a relative movement cylinder, etc., using a fixed outer cylinder type fluid cylinder. And a mechanism to do it. For propulsion,
It is set so that a low pressure in the opposite direction is applied to the discharge cylinder, etc., and a circulating circuit is provided in each pressurizing circuit.
A fluid engine that uses the principle of circulating motion of balance action, which is a motion whose main input is pressurized pressure.

[0001]

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. It is an object of the present invention to provide a simple and durable structure and a principle of movement of a low-power circulating engine.

[0002]

[Prior art] In a circulating fluid engine that moves with pressure as the main input, the principle of the circulating motion is the same but the method of generating the motion is various. Reduction of durability due to vibration was an issue to be solved.

[0003]

[Problems to be solved by the invention] The problem of the structure development is in the development of a fixed structure method for the cylinder used.

[0004]

In the present invention, the outer cylinders of the propulsion cylinder and the discharge cylinder are fixed, and a low pressure is applied in the direction opposite to the propulsion direction, so that the difference between the forward and backward thrusts is obtained. It features a mechanism that generates differential motion due to.

[0005]

[Operation] The structure of this engine is as shown in FIG.
The mutual thrust of the outer cylinder fixing cylinders 6, 15, and 17 is arranged to oppose each other via 29 balance action gears, and at the same time as the high pressure pressurization of the circuit 7 at the time of forward movement, the reverse pressurization circuit of 8 It features a placement circuit that applies low pressure and generates differential motion due to the difference in thrust.

In the case of the forward movement of the embodiment shown in FIG. 1, if the forward valve 5 is turned on and the circuit 7 is equally pressurized, the leftward propulsion movement indicated by the 14 propulsion cylinders 21 is obtained. Although it occurs, it guarantees the back pressure of 16 discharge cylinders 1
Reverse pressure thrust is generated at 17 by pressurization of 1 normal pressure circuit.

Therefore, in the case of a normal circuit, no motion occurs due to the opposing thrust. Therefore, the reverse thrust is halved by applying a low pressure of less than about half to the reverse circuit of 8, so the effective thrust is also halved, but the starting input is also halved, so that the output of this engine is sufficient. Is possible.

If a differential motion is generated due to the difference between the low pressure and the high pressure of the propulsion cylinders 14 and 15, an equal volume circulating flow between the cylinders does not require the inflow of fluid from the two pumps, and only inputs pressure. Continues the propulsion movement. The above-mentioned motion is generated, which is the principle of Pascal. (If one point of the fluid filled in the container is pressurized, it is transmitted to the entire inner surface of the pressure vessel). It is an application and development of the theory.

Exercise efficiency using only pressurization as input is several tens times higher than conventional fluid engines. Therefore, in the volume of each cylinder of the embodiment,
Even if 10 liters are used, it becomes possible with 11 pumps 0, 5 hp, 2 pump inputs and 2 hp,
The above explanation is the principle of circulating motion generation, and the input saving effect is very clear. The structure and exercise of this engine will be described with reference to FIGS. 1 and 2 of the embodiment.

[0010]

FIG. 1 shows a reciprocating engine having a structure in which a balance gear is used as an intervening mechanism and a propulsion cylinder and a discharge syringe are arranged in series. Figure 1 shows the state at the backward end at the time of forward start. Fig. 2 shows the state where it has reached the forward end. This will be explained with reference to Fig. 1. First, if the pump is driven, the normal pressure side of 16, 17 will be pressurized through the normal pressure circuit of 11. No thrust will be generated because the thrust is balanced.

Next, when the forward valve 5 is turned on and the circuit 7 is pressurized, the thrust of the fourteenth and the seventeenth is reduced, and the thrust of the fourteenth is generated. As shown in FIG.
Is reached. When it reaches the forward position, it is detected by the limit switch etc., the valve 5 is turned off, the pressure is reduced by the check valve 3 and the pressure reducing valve 3 etc. Then, the reverse valve 6 is turned on.
If it is set, the circuit 8 will be equally pressurized, and the thrust of 15 will generate a rightward retraction movement of 18 propulsion axes.

The internal fluid of 17 and the circulating circuit of 10 generate a circulating flow of 15 and therefore do not require the inflow of fluid from the pump. Both the output of the propulsion shafts 18 and 19 and the reciprocating motion during the movement are transmitted to the output shaft 27 as one-way rotation of the gear with 26 clutches. When reaching the retreat end, the position is detected by the limit switch, etc., the valve of 6 is turned off, the pressure is reduced by the check valve of 3 or the pressure reducing valve, etc. Then, when the forward valve of 5 is turned on, the forward movement is started again. .

The reciprocating motion cycle is continued by repeating the above procedure. However, it can be said that the movement is performed only by the pressure.
One-half of the fluid flow is required. One-tenth of this is the replenishment of the amount of released fluid required for decompression during stoppage. Therefore, a variable pressure pump or a low pressure / high pressure
It is necessary to install a step input method. However, because of the residual pressure method in this engine, it is possible to apply one step pressure.
It has the effect of starting up with less input than step pressure.

The above is an explanation of the structure of the embodiment and the principle of movement. As described above, since the main input is the pressurized pressure of the fluid of the present engine, it can be said that the provision of a prime mover which is several times as large as the output efficiency of the conventional fluid engine, and is expected to have extremely high output efficiency. You.

[0015] In addition, in the exercise process of the embodiment, as a method of eliminating a pause time loss at the time of switching, it is effective to use an alternate starting method in parallel with two or more sets of the mechanism of the embodiment.
Also, instead of the balance interposition method, whether it is a roller and a smooth moving surface,
It is possible to use a manufacturing method in which a gear and a rack shaft, a pulley and a wire or a relative motion cylinder are interposed. In addition, a direct countermeasure method of the cylinder output shaft can be manufactured without using the balance function.

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. It is also possible to use the one-way motion of this engine and use it in combination with other machines. also,
It is also effective to use a reversible pump in alternate pressurization. It is also possible to use a single propulsion cylinder. Also, instead of the residual pressure, a low pressure pressurization method using another circuit is also possible.

[Effect of the Invention] Since the circulating pressure engine of the present invention is mainly used as the input pressure, 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 such as a vehicle and a ship, and a driving motor such as a generator and a refrigerator.

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. It is an object of the present invention to provide a principle and structure of a simple and accurate movement of a low-power circulating engine.

[0002]

2. Description of the Related Art In a recirculating fluid engine that moves with pressure as a main input, a Y, T-shaped arrangement method, a method of inflow / outflow of fluid from an accumulator by a low differential pressure pump, etc. have been filed. Each has its own problems in power efficiency.

[0003]

In particular, in a system using an equal pressure pump, the pressure on the discharge side increases and the input power increases, which is the biggest problem in efficiency. There was a problem with the efficiency and the complexity of the structure in the Y, T-shaped arrangement.

[0004]

According to the present invention, in the arrangement in which the cylinders are opposed to each other, by selecting a circuit for opposing the total pressure, the arrangement is such that the pressures on the suction side and the discharge side of the pump can be equalized. The feature is that the movement of the fluid inside the cylinder is generated by the rotation of the isobaric pump.

[0005]

[Function] Basically, there are two types of the structure of this engine. As shown in the first embodiment of FIG. 1, a cylinder of the outer cylinder moving type and the outer cylinder fixed type is used, and the cylinder arrangement itself has thrust. ,
A method in which the pump rotates backward mainly by the reverse rotation of the constant pressure pump. As shown in the second embodiment in FIG. 3, the cylinder itself does not generate any thrust and moves by the rotation of the constant pressure pump. However, both circuits are always pressurized to the full pressure in each circuit of the cylinder, and therefore are characterized by the absence of pressure difference between the suction side and the discharge side of 10 pumps.

The characteristics of the constant pressure pump will be described. In pumps such as water pressure and hydraulic pressure, the input load increases in proportion to the difference in pressure between the suction side and the discharge side and the discharge amount. Furthermore, when there is no difference in pressure, the phenomenon that the amount of input is limited to a small amount even if the amount of discharge increases is confirmed and used. ,
Therefore, with 10 pump circuit pressures of 50 kg / cm ² and a discharge rate of 10 liters per second, it is possible with 10 input 5 horsepower.

In the case of a normal hydraulic circuit, about 10 liters per second requires about 100 horsepower. However, if the pressure on the input side and the output side of the pump is the same or the pressure on the input side is high, the above-mentioned light load phenomenon occurs. The present invention applies the characteristics of the fluid motion of the above-mentioned constant pressure pump. Fluid motion engine.

Assuming that the cylinders 12 and 13 of the embodiment shown in FIG. 1 have a pressure receiving area of 100 ^cm2 and a stroke of 1 m, the cylinder moves at a speed of 1 m per second because the internal volume of the cylinder is 10 liters. This is an equal volume circulating motion that does not require external input. Therefore, the theoretical efficiency of a motion that receives only pressure as input is
It provides several tens of times the energy saving effect compared to conventional fluid engines.

The output is calculated by the following formula: pressurized pressure x pressure receiving area x speed. As explained above, the effect of generating a circulating motion by using a constant-pressure pump is very clear, and the effect of saving power compared to conventional fluid engines is very clear. Further, the structure and movement of the engine will be described with reference to FIGS. 1 and 2 of the embodiment.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment in which outer cylinder moving cylinders 14, 15 are pressurized by a normal pressure circuit 4 and 19, respectively.
Gears are stationary by opposing forces due to thrusts in 23 directions. Figure 1 shows the state at the backward end at the time of forward start. Fig. 2 shows the state where it has reached the forward end.

Next, when the motor 9 is rotated in the discharge direction 21, the internal fluid 14 moves and the cylinder 14 moves forward in the direction of the cylinder outer cylinder 29. At the same time, 13 and 15 cylinders 1
Fluid movement becomes 3-15 from 3 and retreat movement in the direction of 18 axis 30. When the 17 propulsion shafts reach the forward position, they are detected by limit switches and the like.
If it is reversed in the discharge direction of 2, it will be the retreating motion of 17 propulsion axes. If 17 propulsion axes reach the retreat terminal, 1
If the 0 pump is rotated forward to discharge in the 21 direction again, the propulsion shaft will move forward at 17 meters, and the propulsion shaft will continue reciprocating at 1 meter per second.

The outputs of the propulsion shafts 17 and 18 during the movement are transmitted to the output shaft 27 as unidirectional rotation of the gear with the clutch 26 only during forward movement. 2 in the above exercise
The pump input can output about 0 or 5 horsepower. As described above, since the present engine is a closed circuit engine and the main input is the pressurized pressure of the fluid, an extremely high output efficiency that is several times as high as the output efficiency of the conventional fluid engine is expected. It can be said that it is a prime mover.

In the second embodiment of FIG. 3, since 12 is forward and 14 is backward, the back pressure is applied to the cylinders 14 and 15 by the circuit 7 and the thrust is lost. Therefore, it is a method that 12 pumps are filled by 10 pumps to make forward movement. The above is an explanation of the principle and structure of the movement of this institution.

In FIG. 1, it is also possible to use the cylinder at the normal pressure side or the piston shaft side. In addition, it is possible to use any type of movable outer cylinder or fixed outer cylinder. In addition, in the exercise process of the embodiment, parallel installation by two or more sets of the embodiment mechanism is effective as a method for eliminating the pause time loss at the time of switching.
Is also possible.

The speed of the motor can be adjusted by adjusting the number of rotations of the motor and by adjusting the flow rate of the circuit. The addition of a small pump, accumulator, dynamo, battery, etc. makes it possible to use it as an independent engine. It is also possible to use the one-way motion of this engine and use it in combination with other machines. It is also effective to use the auxiliary pressurization of the 5- or 6-way valve only on the pump suction side.

[Effect of the Invention] Since the circulating pressure engine of the present invention is mainly used as the input pressure, 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 such as a vehicle and a ship, and a driving motor such as a generator and a refrigerator.
