Description

Detailed Description of the Invention

[0001]

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 motion generating engine that uses pressurized pressure as a main input due to internal volume circulation of siliciders in equal pressure application of fluid.

[0002]

[Prior Art] Currently, there is an application for a cylinder equal pressure differential motion engine, but no practical product has been developed.

[0003]

[Problems to be Solved by the Invention] If a cylinder circuit is developed that can produce a large output by reducing the motion stroke, it becomes possible to establish a motion generating engine that receives only fluid pressure as an input. Was a long-standing challenge.

[0004]

In a two-axis arrangement of multi-stage gears, when a fixed rack is placed inside and gear shafts are arranged on both sides, a cascading action remains and the direction of counter thrust is parallel to the fixed rack. Since it is not possible, there are solutions such as bevel arrangement or three-axis configuration or use of planetary gears, but because the structure is complicated, mesh the counter gear of the second axis on the side away from the fixed rack. Solved the problem.

The first axis multi-stage gear that meshes with the fixed rack works by the action of the journal, but the second axis multi-stage gear that is installed at a position apart from the fixed rack eliminates the action of the court and the transmission function of the rotation action. Is restored, and it becomes possible to select the thrust force point from any direction.

[0006]

[Function] If it is possible to select the force application point from any direction, the phenomenon that the cylinder piston does not move by rotating the gear shaft in the backward direction while the gear shaft moves forward, and while maintaining the propulsive force A stationary cylinder circuit is established.

This is an important discovery because it is possible to input only the cylinder output at rest and the pressure. If the thrust of the stationary cylinder is pressurized by opposing one side of the two cylinders that balance and balance the thrust through the multi-stage gear,
The thrust of the pressurized cylinder is zero, and the thrust of the unpressurized cylinder is fully open. It is a differential motion due to a 2: 1 thrust difference, which is the principle of motion generation by equal pressure. The structure and conditions of motion generation will be explained using examples.

[0008]

[Embodiment] The embodiment of FIG. 1 is a motion explanatory view when the piston rack shaft 10 is moving to the left in the direction of 25. First, 27
The normal pressure circuit of 7 is pressurized, and the cylinders of 7 and 8 are equally pressurized. The propulsion cylinder of 7 exerts the leftward propulsive force 1
I am trying to rotate counterclockwise by meshing with 15 propelling small gears via rack shafts of 0 and. Furthermore, it tries to rotate 14 gears clockwise by meshing with 14 propulsion gears through 8 propulsion cylinders and 12 rack shafts, but it does not move because thrust is balanced.

Although the cylinders 7 and 8 have the same volume as the propulsion force, but they do not move in opposition through a stepped gear having a diameter three times that of the fixed rack 11 which meshes with the small gear 15 It is a fulcrum, the distance to the load points of the rack shafts of 10 and 12 is the same, 10 cm, and it works as a reduction gear, and it operates on the principle of action of the lever.

Next, when the leftward valve of 3 is turned on, it passes through the pressurizing circuit of 5 to pressurize the opposing cylinder of 9, because the low pressure check valve of cylinder 9 has filled the fluid. Boosts pressure instantly. In this case, one of the 13 rack shafts is meshed and connected to the upper side of the counter small gear of the rack shaft 17.
It becomes the propulsive force that rotates the large gear 6 in the clockwise direction, and it blocks the clockwise rotation of the 12 rack axis propulsive forces of the cylinder in 7.

Since the diameters of the counter large gears and the small gears of 16 and 17 are set to 1/3, the pressure receiving area of the cylinder of 9 is set to 3 times that of the cylinder of 8, and therefore the diameters of 14 and 16 are set. Since the thrusts at the meshing points are the same, the reverse thrust of the cylinder 8 disappears, so that only the total thrust of the cylinder 7 is developed, and the propulsion pinion 15 rotates in the counterclockwise direction.
It moves to the left as indicated by 25 because it meshes with the fixed rack frame of 1. In short, the counter differential output of 7 plus 9 thrust and 8 thrust becomes the theoretical output.

During a leftward movement, one rotation of the gear of the rack shaft 15 of the rack shaft 10 having a diameter of 10 cm results in a movement of 60 cm to the left, and because of the circumference of the wheel gear of the rack shaft 12 having a diameter of 30 cm, It is planned to move 90 cm to the right, but due to the gear shaft moving 30 cm to the left, the deduction will be 60 cm. Therefore, the internal fluid of the cylinder of 8 is the total volume circulation of the cylinder of 7 with the same stroke, and since it is filled with the propulsion fluid, it does not require inflow from the pump and moves to the left with the full propulsion force of the piston 7 It is possible to exercise only with the input pressure.

The 13 opposing rack shafts, the 15 propelling small gears and the 17 opposing small gears are set to have the same diameter of 10 cm, and if the 15 small gears make one revolution in the counterclockwise direction, they will move to the left by 30 cm. However, the rotation of the small gear of 17 turns clockwise, the rack shaft of 13 moves to the right, and since it becomes the same after subtraction, the counter cylinder piston of 9 does not move, so the input pressure rises at startup. Only input is possible.

The piston of 9 moves in proportion to the change of the diameter of 17 small gears. If the diameter is made small, the internal volume is discharged and the output can be increased, and if the diameter is made large, the input is increased.

As described above, only the pressurization of the cylinder 9 causes the leftward motion of the cylinder 7 to be continuously transmitted to the crank wheel 22 to reach the leftward end, that is, the limit switch, the cam, etc. Detected by the
If the circuit of 5 is depressurized and the rightward valve of 4 is turned on,
Since the counter cylinder thrust of 9 operates in the direction that pressurizes the circuit of 6 and decreases the cylinder thrust of 7, the cylinder of 8 exerts propulsive force and moves to the right.

The propelling cylinder counteracted by the counteracting cylinder thrust of 9 changes into a discharge cylinder. By making the above-mentioned reciprocating motion continuous, an equal pressure differential motion engine with a fluid pressure that is an extremely reduced input as the main input is established.

It is possible to arbitrarily select the diameter of the gear and the difference in the diameter. The volume and stroke can be changed if the volume ratios of the cylinders are roughly matched. It is also effective to use a one-way rack, clutch, etc. in the output mechanism, and it is also possible to manufacture with a roller transmission mechanism, planetary gear, etc.

It is also possible to use a wire, a chain one-way clutch, or the like for the thrust transmission mechanism.
Liquids with low compressibility such as oil are effective. It is possible to manufacture by car.

It is also possible to use an accumulator or pressure reservoir tank for pressurizing the atmospheric pressure circuit.
A 9 cylinder simultaneous pressurization start method is also possible. Also, 9
It is also possible to make reciprocating motion by making both sides of the 7 and 8 pistons alternating pressure by making the normal pressure as. In addition, the output shaft is
It is also possible to use the rack axis of 2.

INDUSTRIAL APPLICABILITY The present invention is to provide a fluid engine which uses the pressure of the fluid as the main input, and which is extremely input-saving, and can be used in many fields of application as a prime mover of the future. It is an important invention that is effective for driving presses, lifts, etc. and is also suitable as a prime mover for generators, contributing to future energy problems.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prime mover. It is an object of the present invention to provide an input-saving prime mover engine that generates reciprocating motion of a gear shaft by using a pressure applied as an input by the action of a structure of a pressurized differential gear.

[0002]

[Prior Art] At present, a complete prime mover that uses pressure as an input to move is not developed.

[0003]

[Problems to be Solved by the Invention] The principle of a static pressure engine has been applied for, but as a problem of mechanical efficiency, the boost input required amount is 10%, and as a static pressure engine, it is still too large. It was an immediate research topic to overcome.

[0004]

[Means for Solving the Problems] The principle of a static pressure engine is that when a moving gear is engaged with a fixed rack and the apex of the differential gear is pressurized by a driving rack in the parallel direction, the differential gear is used. It is a truly epoch-making invention in that the drive rack shaft does not move because of the same amount of forward and reverse rotation, but only the differential gear produces a rotational motion due to the transmission of thrust.

However, if the input problem did not progress, it was difficult to put it into practical use as an engine. As a static pressure engine, the external input is 10%, but it is too high, but it is 10
Since the consumption of a percent and the establishment of an engine are possible, the problem was solved by installing an auxiliary cylinder that operates the pressure of the propulsion cylinder with internal thrust.

[0006]

[Operation] When motion is generated, this is possible because of the characteristics of the differential engine in which the propulsion cylinder piston does not move and only the differential gear rotates to generate output. , It is possible to continue the motion of the propulsion cylinder, and it is also possible to reduce the external input at the time of startup by about 5%. Exercises and structures will be explained with examples.

[0007]

[Embodiment] FIG. 1 is an explanatory view of the structural operation of the embodiment. First, if the pump 2 is driven by the cell motor 1
The auxiliary cylinder of 1 is pressurized, and the piston pressure receiving area of the auxiliary cylinder is set to 10% of the propulsion cylinder of 7.

Therefore, since the propulsion cylinder 7 is filled with fluid, the pressure is instantly increased, and thrust is generated in 8 directions to propel the gear headstock 9 in 17 directions. At the same time, 28 pressure switches are activated to stop the starter motor and release pressure on the prosthesis cylinder.

Propulsion of 17 does not stop even if the motor is stopped, because the moving clamp shaft of 22 holds down the retreat of the auxiliary cylinder piston. It has 22 moving clamp shafts and a rack that meshes with the one-way clutch with 23 gears so that it does not move backward when meshed, and it has a structure for left / right and up / down motion.

Output of the gear shaft 19 through the output shaft of the shaft 15
The crank wheel is rotated and output as the rotation output of 20. In the direction of 17 just before the left end, 25 on the right side
The one-way cam pushes up the roller cam of 24 to separate the moving clamp shaft of 22 from the gear one-way clutch of 23, and the auxiliary cylinder of 21 is retracted.
The pressure in the pressurizing circuit of is reduced and the propulsion cylinder pressurization is stopped.

At the same time, the 26 cams on the left side press the 21 ribs on the left side by the inertia to instantly increase the pressure in the pressure circuit of 6, so that the gear shaft base reverses to the rightward movement. The left auxiliary cylinder piston holds the pressed position. The cycle is continued by alternately repeating the above operations on the left and right. Since it requires almost no external input during operation, it is clear how efficient the power saving engine is.

Either the stop or one-way clutch must be disabled or a small amount of relief circuit for the fluid in the pressurization circuit is required. In controlling the speed and output, it is effective to adjust the pressure, back pressure, adjust the flow rate of the circuit by installing a circulation cylinder and pump, and use a pressure switch. The above is the explanation of the principle and structure of the motion of the differential fluid pressure engine with self-powered prosthetic rib cylinder.

It is also effective to use a cylinder for vertical movement of the moving clamp shaft of 22 and operate it with a solenoid valve.
Attach an electromagnetic clutch to the one-way clutch of 23,
A method of releasing the moving clamp axis and stopping the movement is also possible. It is also possible to use multiple propulsion cylinders, pressurize both of them at the beginning, and use auxiliary cylinders alternately as back pressure to generate motion.

If the starter motor cannot be used, it can be started with a manual pump. It is possible to use a pressure reservoir tank, an accumulator, etc. as a pressure source.

EFFECTS OF THE INVENTION The principle of the present invention is to establish the principle of a differential fluid pressure engine without taking out rotational output with pressure as the main input, and to provide a method of manufacturing a power-saving driving engine. It is easy to produce a high-power engine, so it is an important invention that contributes to the energy saving problem as a driving engine for propulsion engines such as vehicles and ships, as well as for presses, lifts, civil engineering machines, and generators.

[Title of Invention] Equal pressure differential fluid engine

[Claims]

The structure is such that the arcuate inclined surface of the differential gear, the roller, etc. is pressurized by the fluid cylinder from the substantially vertical direction via the inclined rack shaft, the inclined smooth shaft, the gear, etc. A propulsion cylinder is provided, which applies equal pressure together with the pressurizing cylinder. Due to the difference in thrust due to the setting of the pressurizing angle of the differential gear, etc., a circulatory motion of the internal fluid between the cylinders is generated, and the fluid pressure is used as the main input. In the pressure circuit of the engine. An equal pressure differential fluid engine in which a smooth shaft or a rack shaft is brought into contact with the back side of the differential gear and pressure is applied by a counter cylinder.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prime mover. The present invention provides a counter cylinder that opposes the thrust of the pressurizing cylinder in the pressurizing circuit of the differential motion engine, which is generated by the difference in the thrust when pressurizing the inclined surface of the differential gear by the fluid cylinder, and thereby improves the output efficiency. Aim to rise.

[0002]

[Prior Art] Currently, a differential engine that moves using pressure as an input is filed, but the output efficiency is not perfect.

[0003]

[Problems to be Solved by the Invention] It is to reduce the resistance of the inclined surface pressure cylinder during the propulsion motion of the propulsion cylinder.

[0004]

[Means for Solving the Problems] By opposing a pressure cylinder that presses and presses an inclined surface of a differential gear, and pulling by holding the opposing cylinder from the rear surface of the differential gear, the thrust of the pressure cylinder is reduced. It is possible to increase the output of the propulsion cylinder.

[0005]

The output efficiency in the horizontal direction when pressing the inclined surface of the differential gear is 0, and the output is 0 when the top surface of the gear is pressed in the vertical direction.
It is a percentage, but there is no thrust difference in the horizontal direction,
Therefore, the output efficiency is about 50% at 45 ° when the thrust difference occurs and about 30% at 30 ° of the embodiment.

The principle of differential motion: As shown in the embodiment of FIG. 1, the thrust of 30% of the vertical pressure cylinder and the thrust of 100% of the horizontal propulsion cylinder are opposed to each other, and the difference in thrust between them is caused. The basic principle is to generate motion by

As shown in the embodiment of FIG. 1, the total volume of the pressurizing cylinders 10, 11 and the volume of the propelling cylinders of 19 are set to be the same. Therefore, when the thrust forces are opposed to each other, the thrust force difference causes the forward movement of 19 cylinders. 10 and 11 I will retreat 1011
Because of the cylinder fluid pressure circuit of 30 and the thrust force difference of 30 to 100, 19 cylinders recirculate and move without inflow from the 19 cylinder pump. The above is the second principle of motion.

The volume of the circulatory flow is the diameter of the differential gear. The effect of the circulatory motion is that only 10% of the input capacity needs to flow in at the time of startup for boosting. It has a feature that enables the establishment of an input fluid engine.

[0009]

[Example] The example of FIG. 1 will be described. Fig. 1 It is a structure in which a differential engine is installed in the press and reciprocates up and down. It represents the moving state in the ascending direction indicated by 22.
The ascending valve of 3 is turned on, 19 and 10, 11 are at equal pressure, and the moving direction of 10 and 11 is the descending direction.
The propulsion direction is the ascending direction, and a 30: 100 differential output results in an ascending motion.

In the above structure, the counter thrust of the pressurizing cylinder is 9 by installing 8 and 9 counter cylinders.
It will be reduced to about 0%, and output efficiency with differential theoretical thrust of 10 to 100 is possible.

The feature of the embodiment of FIG. 1 is that it enables movement with an input of 1/10 of the conventional press. When the pressurizing shaft of the counter cylinder 31 is horizontal as shown in Fig. 1, no stroke is required, and because of the normal pressure circuit,
It consumes little input power and has the same effect when descending. In Fig. 1, 31 is horizontal pressurization method, but back slope pressurization is also possible. The back slope pressurization method is effective for increasing the flow rate of the propulsion cylinder.

It is also possible to use a system where 31 and 31 are rack axes. In a rotary type differential engine, it is possible to install a counter cylinder by mounting a cylinder base on a fixed shaft and pushing internal gears, differential gears, etc.

[0013]

INDUSTRIAL APPLICABILITY The present invention is indispensable for a differential engine, and is used as a differential engine in a press, a lift,
It is an important invention that contributes to the energy saving problem as a prime mover including reciprocating engines such as injection molding machines.

[Title of Invention] Equal pressure differential fluid engine

[Claims]

1. The force application points of a plurality of fluid cylinders have a concentrated shaft attachment structure and are arranged in a counterbalanced arrangement such as an arrow shape, a Y shape, or a T shape. Alternatively, the balancing arrangement may be a composite arrangement such as series or parallel arrangement, and the structure is such that the thrust of each cylinder directs the balanced differential position by equal pressure to output the restored differential thrust. Alternatively, a structure in which a plurality of cylinder thrusts are opposed to each other via a rack gear, a differential roller, etc., and differential output is generated by equal pressure is applied. At equal pressure, a difference in thrust is generated by changing the opposing position and opposing angle of the opposing cylinder thrusts, and the movement of the internal fluids is generated continuously so that the motion continues, and the fluid pressure is the main input. Equal pressure differential fluid 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 low input fluid engine.

[0002]

[Prior Art] At present, an application has been filed for a fluid engine that moves using pressure as an input, but it cannot be said to be perfect.

[0003]

[Problems to be Solved by the Invention] The principle of motion of a constant pressure fluid engine is to generate a thrust difference in opposition to the thrust of a cylinder of approximately equal volume to generate a differential motion.

[0004]

Means for Solving the Problems In generating a difference in thrust force in equal pressure of cylinders, a plurality of cylinders having an arrow-shaped, Y-shaped, T-shaped, etc. balanced arrangement structure or a differential gear is interposed. It is established by changing the thrust opposing position, angle, etc., depending on the cylinder thrust opposing structure.

[0005]

The feature of the balancing arrangement counter circuit is that, as shown in the embodiment of FIG. 2, the counter direction angle between the thrust direction of the propulsion cylinder 7 and the thrust direction of the counter rib cylinders 8 and 9 that oppose is changed. Therefore, thrust difference occurs. Therefore, T in FIG.
If you press the letter arrangement, the thrust in the 12 directions becomes dominant,
The motion of restoring thrust to reach the Y-shaped arrangement in Fig. 3 is generated, the angle of each piston axis becomes 120 degrees, and the motion stops at the thrust balanced position.

When the T-shaped arrangement shown in FIG. 4 is pressurized, the movement is continued until the arrow-shaped arrangement shown in FIG. 5 where each piston axis angle is 45 degrees is reached. The above two examples are basic exercise forms of balancing arrangement.

A further important feature of the balancing arrangement is that if the cylinder is filled with fluid at startup,
The pressure is boosted at the input of 1/10 of the total cylinder volume,
There is a point of origin to be a motion-saving motion fluid engine that can be operated only by input from the pump because the circulation of the cylinders is generated and satisfied at the same time when the motion starts.

However, there is a weak point of the balanced arrangement restoring position movement, that is, the thrust of the cylinder becomes zero at the equilibrium complete position because the entire stroke of the cylinder does not have the same thrust, so the effective movement distance is shortened. The method that overcomes the above weak points is the first embodiment of FIG.

[0009]

[Example] The example of FIG. 1 will be described. Fig. 1, a linear reciprocating engine, is a structure that reciprocates left and right, and the state at the time of starting is expressed in the left direction shown by 12. When the leftward valve of 3 is turned on, the solid line part of the cylinder of 7, 8, 9, 13, 14, 15 becomes equal pressurization through the pressurizing circuit of 5, and the propulsion cylinder of 7, 13 moves to the left. Thrust is generated.

The T-shaped arrangement of 7, 8 and 9 moves to the arrow-shaped arrangement according to the leftward movement, and the thrust is reduced.
The thrust is increased due to the movement of the arrow-shaped arrangement of 4 and 15 to the T-shaped arrangement according to the leftward movement, so that the total thrust of 7 and 13 has a theoretical thrust of 120% if the maximum is 200%. Exercise of the whole process is possible.

The fluid required for the propulsion cylinder during movement 8,
Since the refilling is performed from the 9, 14, and 15 supplementary rib cylinders, a fluid-saving input engine that does not require the inflow of fluid from the pump is established.

When it reaches the left end, it is detected by a limit switch etc. and the left and right reciprocating motions are made continuous by switching the solenoid valves 3 and 4, and the output is transmitted to the 19 crank wheels.
By using a one-way rack as the output method, it is possible to achieve high rotation output.

In the embodiment shown in FIG. 1, since the starting cylinders 22 and 23 are attached, the solenoid valves 3 and 4 are not used except at the time of starting.
Pressing the starting cylinder of 2 to raise the pressure of the pressurizing circuit of 6, further actuating the release valve of 25 to depressurize the circuit of 5 shifts to the rightward movement.

When the rightward end is reached, the 23 starting cylinders are compressed, and if the 24 release valves are activated, the cycle shifts to the leftward and the cycle continues. The volume of the starting cylinder is 1/10 of the total cylinder volume. The above is the explanation of the principle of motion and structure of the equal pressure fluid engine.

This motion principle is the principle of the manufacturing method at the same time, and by applying it, it is possible to manufacture a propulsion device with a differential rack gear, a differential roller, a discharge cylinder, etc., and a direct rotation output device.

When the thrusts of the propulsion cylinder and the discharge cylinder are opposed to each other by interposing the differential rack gear, both cylinders are arranged in parallel with the rack, and the slope of the differential gear is pressurized vertically from the discharge cylinder. There is a method to pressurize the propulsion cylinder from the horizontal direction. However, since the output efficiency of both types is low, it is necessary to overcome the reaction of the discharge cylinder by balancing the cylinder arrangement.

The efficiency of the fluid engine of the present invention is extremely high, and the applications of the fluid engine include reciprocating engines such as presses, lifts, injection molding machines, propulsion engines such as vehicles and ships,
This is an important invention that contributes to energy conservation as a driving engine for a generator.

[Problems to be Solved by the Invention] The principle of motion of a static pressure differential engine is characterized in that motion is generated by inputting pressure without the need for fluid movement. The challenge is to significantly increase hydrostatic exercise output.

[0004]

According to the present invention, by applying pressure through the rack shaft from the direction of the circular arc of the inclined surface of the two-stage differential gear, the differential gear requires the movement stroke of the cylinder. It is possible to increase the output by attaching a pressure booster to the equal pressure circuit for static pressure motion that generates rotational motion without stopping.

[0005]

[Operation] In FIG. 1, when the vertical vertices of the 13 differential gears and the 16 inclined pressurizing shafts are pressed against the fixed rack surface from the horizontal direction, they do not move. In the case of pressure, the amount of forward rotation and the amount of backward rotation are the same.

However, by giving a small inclination angle to the inclination pressing shaft, the piston does not move, and only the gear contacts the fixed rack surface and starts to move. The basic structure of static pressure motion is to apply pressure by setting the rotation direction of the gear 13 above the two-stage differential gear in FIG. 1 and the direction of thrust of the inclined pressurizing shaft 7 to be the same.

The propulsion direction of 7 and the rotation direction of the gear are the same, but the piston does not move because the movement direction of the gear axle is opposite. Therefore, the rotation movement of the gear is generated by the transmission of thrust. Thrust conduction is a characteristic of two-stage differential gears. Not only two-stage but also an even-numbered differential gear has the same effect.

Further, a pressurizing system via a tilted rack shaft by a cylinder perpendicular to the fixed rack surface is also possible, however, in the case of pressurization from the vertical direction, the gear moves in contact with the tilted pressurizing shaft. When moving, the pressure shaft fluctuates in the direction of the fixed rack, so the cylinder piston moves,
The inflow from the pump increases and the output decreases. All vertical directions in this description mean the rack surface.

In the above case, as shown in FIG. 1, the vertical cylinder is moved by being held by a gear shaft holding table, and when the inclined pressing shaft is pressed by a pressing roller, the vertical shaft piston is generally moved. It is effective to move the vertical pressurizing shaft together with the gear holder while applying pressure. Motion is generated by pressurization from the vertical direction, due to the angle change action of the pressing line.There is an inclined axis, but motion is generated by the change in the thrust direction from the vertical direction to the horizontal direction. Both methods are proportional to the input angle of the force applied point.

Therefore, if the piston of the propelling cylinder 7 does not move due to the equal pressure and the output of the cylinder of the vertical cylinder 9 does not move, the fluid from the hydraulic pump needs to be introduced. Instead, the static pressure motion with the pressurizing pressure as the main input is established. It is possible to move independently in 7 and 9, but the composite structure is particularly good in output efficiency. The above is the principle of static pressure motion.

The efficiency of static pressure motion is several tens of times that of ordinary hydraulic equipment. Another feature of the present invention is that the efficiency of the differential engine is dramatically improved by installing a pressure booster.

[Example] The press of the example shown in Fig. 1 will be described.
Fig. 1 is a linear motion static pressure engine, which is a structure that reciprocates up and down. The 20 gear shaft holders represent the downward motion of 27. When the down valve of 3 is turned ON, the cylinders of 7 and 9 become equal pressure through the pressure circuit of 5, and the thrust force of 7 and 1
When the right inclined surface of the differential gear No. 3 is also used with pressure, it becomes the starting rotation in the direction of the differential gear wrinkle 18 according to the motion principle explained in the item of action.

During the downward motion of 27, the internal fluid of the propulsion cylinders 7 and 9 generates a motion while being pressurized, and the propulsive motion of the pump is extremely reduced by inputting only the pressurization. However, 10% of the total volume of the inflow is required for boosting only at startup.

Control of motion speed It is possible by adjusting the pressure, but in the case of a press, it is assisted by adjusting the flow rate of the balance cylinder of the press 25. At the detection point of the limit switch on the way down 23, the high pressure switching position, 26 low speed valves and 2
When the high pressure valve 8 is turned on, the descending speed becomes slower, and at the same time, the booster of 29 makes it possible to increase the propulsive force about 20 times. The booster start input is supplied by the accumulator.

Characteristic of static pressure motion It is a point that the pressure booster can be used even during pressurization motion. When reaching the descending terminal 3, 2
The valves of 6 and 28 are set to OF, the release valve of 32 is turned ON, and then the rising valve of 4 is turned ON to raise the valve and complete one stroke.

Installation of pressure booster Not only for press, but also for lift, injection molding machine, etc., it is an effective method for all output amplification of reciprocating type and direct rotating type of hydrostatic fluid engine.

The hydrostatic differential engine of the present invention has a simple structure, and the booster is also marketed as a high-performance product, and a high-output differential engine can be easily established by attaching it. Applications of differential engines include reciprocating engines such as presses, lifts, injection molding machines, civil engineering machines, propulsion engines such as vehicles and ships,
This is an important invention that contributes to energy conservation as a driving engine for a generator.
