Abstract

PROBLEM TO BE SOLVED: To reduce the extent of reverse thrust in a discharge cylinder as well as to make improvements in output efficiency by setting up plural pieces of those that convert a thrust direction of this discharge cylinder in opposition to a propelling cylinder into a turnover direction by dint of gears and so on, and linking up these elements with one another by means of leverage. SOLUTION: At a time when a forward propelling cylinder 11 is started in the forward direction, a pump 2 is driven and a normal back-pressure applying circuit 9 is pressurized, and thereby each back pressure part of two discharge cylinders 13 and 14 for both forward movement and backward movement is made into an equi- pressurized state. Each thrust of these discharge cylinders 13 and 14 is immovably placed at an equilibrium as two rack shafts 17 and 18 in mesh with turnover gears 19 and 20 are linked up with one another by a balance 25. Next, if an ahead valve 5 is opened, and ahead pressurizing circuit 7 is pressurized, the forward propelling cylinder 11 and the discharge cylinder 13 are made into a state of equi-pressurization, and a thrust is generated, thus moving the rack shaft 17 to the left. At this time, an internal fluid turns to an equi-capacity round floe through a round flow circuit 26, and thus a continuous propulsive motion is carried out.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. SUMMARY OF THE INVENTION The present invention is directed to the production of a power-saving fluid prime mover by providing the principle of hydrostatic differential motion.

[0002]

[Prior Art] At present, the principle of generating motion by moving fluid inside a fluid engine is the principle.

[0003]

[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 physical pressure without requiring fluid movement.

[0004]

SUMMARY OF THE INVENTION In the present invention, by applying pressure through a rack shaft from the direction of the arc of the inclined surface of a two-stage differential gear, the differential gear requires a movement stroke of a cylinder. It is the point that they discovered that a rotating motion was generated without performing the operation.

[0005]

In FIG. 1, when the vertical apex of the differential gear 13 is pressurized from the horizontal direction with the inclined pressurizing shaft 16 horizontal, no motion occurs. Because, the forward rotation amount and the backward rotation amount 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.

[0008] Further, a pressurizing method through an inclined rack shaft by a vertical cylinder is also possible. However, in vertical pressurization, when the gear moves in contact with the inclined pressurizing shaft, the pressurizing shaft fluctuates upward or downward.Therefore, the cylinder piston moves and the inflow from the pump increases. The output will decrease.

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 bending action of the pressure line, the tilt axis is interposed, but motion is generated by the change in the thrust direction from vertical to horizontal. Both are proportional to the input angle of the applied point.

Therefore, if an output is generated in a state in which the piston of the propulsion cylinder 7 does not move due to equal pressurization and the piston of the cylinder 9 in the vertical axis direction does not move, the fluid from the hydraulic pump needs to flow. Instead, a complete hydrostatic engine with pressurized pressure as the main input is established. Both 7 and 9 can move independently, but the composite structure has good output efficiency. The above is the principle of static pressure movement.

[0011]

[Embodiment] A first embodiment of FIG. 1 will be described. FIG.
It is a linear reciprocating differential engine and has a structure that reciprocates left and right. The 20 gear shaft holders represent the state during the leftward movement indicated by 27. If you turn on the left valve of 3,
Since the cylinders 7 and 9 are equally pressurized through the pressurizing circuit 5 and pressurize the pressurizing thrust 7 and pressurize the right inclined surface of the differential gear 13 via the inclined pressurizing shaft 16, the action items are increased. According to the principle of motion described in the above, the rotation starts in the direction of the differential gear 18.

During the leftward movement of 27, the internal fluids of the propulsion cylinders 7 and 9 generate a motion while being pressurized, and the propulsion movement with extremely low input by only the pressurization input from the pump. Is possible, but it is necessary for inflow of 10% of the total volume at startup.

When reaching the left-hand end, it is detected by a limit switch or a cam, etc., and the left-hand valve 3 is turned OFF, and the release valve 25 is turned ON.
Release 10 percent of 28 compression cylinders. Next, if the valve 25 is turned off and the right-hand valve 4 is turned on, the circuit 6 is pressurized and moves to the right-hand motion.

If the operation returns to the end of the right line, the cycle is continued by repeating the same procedure. However, from the second time, 10% of the fluid flows from the starting compression cylinder, enabling motion that does not require the flow of fluid from the pump, which is an extremely effective power saving effect.

The output power is alternately transmitted from the two gear shafts to the 39 gears via the 21 and 22 flexible shafts and the 23 and 24 one-way clutch gears. 40 rotation output shafts rotate in one direction. In addition, it is also effective to use a one-way clutch with a rotating shaft as the rack shaft so that the output shaft reciprocates linearly in the direction of 27. In addition, a rotation output method using a crank is also possible.

[0016] In addition, a pressure roller in an inclined axis direction and a vertical axis direction, an electric motor, a magnet, a spring, a screw tightening mechanism,
Use of physical pressure such as hydraulic pressure is also possible. Also, it is effective to equilibrate cylinders such as Y-shaped and arrow-shaped cylinders in the vertical direction. In addition, it can be installed as a mechanism that can move the vertical cylinder to the upper frame, and it can be manufactured with differential rollers.

The second embodiment shown in FIG. 2 uses a fixed spur gear,
Direct rotation output method. The feature is that the inclined pressurizing shaft is installed every 90 degrees and pressurizes sequentially. Furthermore, a 3-position switching valve and a short-circuit valve are provided to reduce the input at the time of switching by half.
It uses a low input method. Large-capacity output with many fixed frames is also possible.

Third Embodiment FIG. 3 shows a direct rotation system using a fixed spur gear. The inclined pressing shaft is changed to an eccentric moving type internal gear, and a vertical pressing cylinder is mounted on a fixed shaft around the center. It is characterized by the fact that the pressure valve is not switched instantaneously.

In each of the embodiments, if a small pump, an accumulator, a dynamo, a badge, etc. are attached, the operation as an independent engine is possible. Also, it can be replaced by the solenoid valve cam operation.

The differential engine using the static pressure motion according to the present invention has a simple structure, has a very high output efficiency, and is used for a reciprocating engine such as a press, a lift, an injection shaping machine, etc. It is an important invention that contributes to energy conservation as a propulsion engine for vehicles, ships, etc., and also as a driving engine for generators.

A structure that can be moved by contacting a fixed rack, a fixed spur gear, a fixed internal gear, a fixed smooth surface, and the like by using a differential gear, a differential roller, and the like that move a rotation axis. The differential gear and the circular roller surface of the differential roller are pressed by a sector gear, a sector cam, or the like via an inclined pressure shaft or an internal gear. A differential engine that uses the principle of static pressure motion, which uses a fluid cylinder, spring, screw, electromagnet, etc. as the pressurizing structure and converts the pressurized pressure into rotary motion.

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 manufacture a power-saving differential engine based on the principle of static pressure differential motion.

[0002]

[Prior art] The current fluid engine has extremely low efficiency because it is based on the dynamic pressure that generates motion by the inflow movement of external fluid.

[0003]

[Problems to be Solved by the Invention] The principle of motion of a hydrostatic differential engine is characterized in that motion is generated by inputting pressure without moving fluid.

[0004]

According to the present invention, the pressure cylinder piston shaft is changed by the action of a pressure rack shaft on the inclined surface of the gear, a sector gear attached to the pressure internal gear, and a sector cam. The feature is that the static pressure thrust is converted into a rotary motion without causing it to run.

[0005]

[Function] Principle of static pressure differential motion, linear thrust of piston, etc., in pressurizing circular inclined surface of differential gear, force line of thrust by rotation of gear It was discovered that by changing to, it is possible to generate a rotational motion of the gear.

Normally, when the inclined surface of the differential gear is pressed, the position of the pressing shaft fluctuates in conjunction with the rotational movement of the gear. Static pressure motion is not established because the piston position fluctuates. Methods for compensating for fluctuations in the pressurizing shaft include the simultaneous movement of the pressurizing piston shaft, the simultaneous rotation of the pressurizing internal gear, and the interposition of a fan-shaped cam in the pressurizing circuit.

In the present invention, the use of a sector gear on the piston pressurizing surface allows the pressurizing angle of the piston to be optimally maintained, so that the transmission efficiency of the pressurizing thrust is high, and even if the tilting pressurizing shaft fluctuates, the piston pressurizing force is increased. The feature is that it does not fluctuate. Pressure can be applied even with the sector cam method, but the thrust transmission efficiency of the sector gear is inferior.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first embodiment shown in FIG. 1 is of a continuous rotation output type in which a differential gear is sequentially pressed. A structure in which two-stage differential gears 20 and 21 rotate around 19 fixed spur gears.
Furthermore, the structure is such that 16 internal gears, which engage with the 21 auxiliary gears, pressurize the 21 inclined surfaces of the gears and move freely.

The inclined pressure shaft provided with 15 sector gears is in contact with the back surface of the floating internal gear, and the inclined gear shaft is further insulated by 11 pressure cylinders through 14 pressure gears. Thrust is pressurized. However, the pressurizing cylinder and the tilting shaft with fan gear are arranged at 120 degree intervals.

At first, the hydraulic pump 2 is driven, and the starting valve 5 is turned on, the cylinder 11 is pressurized through the pressurizing circuit 8, the thrust of the cylinder 15 and the inclined shaft of the fan gear 15. Press the inclined surface of 21 differential gears through the internal gear.

The rotation of the pressurized gear 21 in the direction of the wheel 18 is generated, and the rotation of the wheel 24 in the direction of the rotor 26 is generated.
It moves 20 degrees, the angle of the tilt axis changes according to the gear movement, but the position of the piston does not change due to the action of the sector gear, so it can be said that the static pressure differential motion is established. 12
If the 0-degree movement position is detected by a limit switch, a cam or the like, and the starting valve 5 is turned ON and the starting valve 6 is turned ON,
It will be a further 120 degrees.

As described above, by sequentially pressurizing the start valves 5, 6, and 7, the 24 rotors can be continuously rotated, and the output is transmitted to the 28 rotating shafts via the 27 output gears. In addition, since the piston does not move, the cylinder stroke can be as small as one centimeter. The above is an explanation of the principle and structure of static pressure motion.

As a target arrangement of the first embodiment shown in FIG. 1, a fixed internal gear is provided on the outer periphery, a structure in which the differential gear rotates by meshing with the internal gear, and an additional gear having a sector gear through a ring-shaped internal gear. It is also possible to manufacture a method of applying pressure from the center to the outer periphery with a pressure shaft.

Control of output, speed, stop, etc. Possible by adjusting pressure, back pressure, etc. In each embodiment, it is possible to manufacture with differential rollers, etc., and pressurizing method with springs, screws, electromagnets, etc. is also possible.

Also, if a small pump, accumulator, dynamo, battery, etc. are attached, it can be used as an independent engine. Also, the solenoid valve and cam valve can be replaced.

The differential engine using the principle of the static pressure motion of the present invention has a simple structure, has a very high output efficiency, and is used as a differential engine in presses, lifts, injection molding machines, civil engineering machines, etc. Propulsion engines such as vehicles, ships,

[Title of the Invention] A differential engine using the principle of static pressure motion

[Claims]

1. A differential mechanism capable of rotating by contacting a rack, a gear, a roller, a smooth shaft surface, or the like using a pressure gear, a pressure roller, or the like. A structure in which the shaft of the pressing gear, the pressing roller, or the like is eccentric or the one-side output of the pressing surface is transmitted to a gear, a rack, a roller, a smooth shaft surface, or the like by providing a one-way rotating cam, a clutch, or the like. Whether the transmitted self-propelled thrust reverts to the receiving surface on the opposite side of the pressing surface of the pressing gear, pressing roller, etc. A differential engine that uses the principle of static pressure motion and has a structure in which a plurality of pressurizing shafts are used and a thrust circuit or the like is used to indicate mutual regression of thrust.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor. SUMMARY OF THE INVENTION An object of the present invention is to provide a power saving engine that converts pressure into motion.

[0002]

2. Description of the Related Art At present, a finished product of a hydrostatic differential engine is not provided.

[0003]

[Problems to be Solved by the Invention] The problem is how to convert the linear thrust of only the pressure generated by the motion of the hydrostatic differential engine into the rotational motion.

[0004]

The first feature of the present invention is as follows.
Either the pressurized thrust shaft is connected to the pressurizing gear, the shaft attachment is eccentric, or a one-way rotating cam, clutch, etc. is installed in the shaft attachment. With the eccentric mechanism and the one-way clutch attached, one side of the pressurizing surface of the pressurizing gear is set to the output side, and the opposite contact surface is set to the receiving side.

The second feature is that the thrust of the tooth surface on the eccentric side of the pressing gear is transmitted and returned to the receiving side of the pressing gear through a thrust circuit such as a rack, an output gear, and a rack. The reciprocal regression of the multiple pressure axis method in the embodiment of FIG. 2 has the same effect. The principle of the structure of the generation of one-sided thrust, the regression of equality of thrust, and the static pressure motion by the above two characteristics.

[0006]

[Function] If pressure is applied without eccentricity of the shaft of the pressure gear, it will not move at all or will be idle depending on the pressure angle.
With an internal gear type eccentric mechanism, even without a one-way rotating cam, clutch, etc., it is possible to rotate the gear shaft without moving by installing a thrust regression circuit. In the case of a non-eccentric shaft equipped with a one-way rotation clutch, rotation is possible without the gear shaft moving if there is a regression circuit. It is a cam eccentric type mechanism and requires a one-way rotary clutch and a return circuit.

In the present invention, since the rotation of the pressure shaft stroke is very small, a rotating motion is generated with the input of the electromagnetic force via the fluid cylinder, the spring, and the pressure of the screw tightening mechanism, etc., so that the prime mover having extremely high output efficiency is obtained. Can be provided.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The principle of the structure is easy to understand.
The second embodiment is a reciprocating differential engine, which will be described with reference to an embodiment. This is a reciprocal reciprocating method that simultaneously pressurizes from the left and right by 8 and 9 fluid cylinders with a piston pressurizing shaft.
The eccentric gear mechanism for pressurizing gears 12 and 13 with a one-way rotating cam. This is a left-rotation effective clutch set in the 16th rotation direction.

[0009] Ten output gears in the center, 12, 13
The rack shafts 18 and 19 are 20 and 2
It is a structure that reciprocates right and left as shown in 1. When the pump 2 is driven at the beginning, the cylinders 8 and 9 are pressurized through the pressurizing circuit 5 and thrust is generated in the direction indicated by 15 opposite to each other.

Since the pressure gear 12 is eccentric to the rack side 18 and the effective direction of the rotational output is set to the direction 16, it is transmitted to the rack shaft of the thrust wheel 18 and the right direction of 21 is transmitted. And rotate the 10 output gear. 1 at the same time
The pressurizing gear 3 is also in a pressurized state and is eccentric to the 19 rack side, so that the 19 rack shaft is moved and the receiving side of the 10 output gear and the 18 pressurizing gear is moved.

Although it moves in the directions of the rack shafts 20 and 21 of 18, 19, the rotation is continuous at the current position without moving the pressurizing gear shaft of 12 because the moving amount is the same. The 13 pressure gears are also in the same state. When returning, it is possible by pressurizing the pressure circuit of 6. If the output method is linear reciprocation, it can be taken out directly from the rack shaft. In the case of rotary motion, a rotation direction conversion device with multiple unidirectional rotary clutches or a crank wheel is required.

In addition, since the cylinder pressurizing shafts 8 and 9 do not move because the pressurizing gear shaft does not move, the stroke does not move. Therefore, it is possible to use only a small amount of fluid, so that a power-saving prime mover that inputs only pressure is realized. . The above is an explanation of the principle and structure of a reciprocating propulsion type static pressure differential engine with multiple pressurized shafts.

In the case of the self-thrust regression type, it can be manufactured in a structure excluding 9 pressure cylinders and 13 pressure gears from the embodiment of FIG. The first embodiment shown in FIG. 1 is a continuous rotary motion system using a plurality of pressure shafts. The rack shaft whose movement distance is restricted is changed to 14 auxiliary gears, and the movement principle is the same as that described in the second embodiment.

It should be noted that, in the arrangement of the first embodiment, instead of the 14 complementary gears, a planetary type in which a movable internal gear is installed on the outer periphery enables the production of a continuously rotating hydrostatic differential engine. In addition, even in the static pressure pressurization method of the fan-shaped cam, an internal gear is provided on the outer circumference of the pressurizing gear, and the thrust regression circuit is installed.

It is also possible to manufacture with rollers, smooth shafts, etc. Also small pumps, accumulators, dynamos,
If a battery is attached, it can be used as an independent engine. Also, the solenoid valve and cam valve can be changed. In addition, in the embodiment shown in FIG. 1, the installation direction of the pressurizing shaft and the pressurizing gear can be selected.

The principle of the structure of the present invention for converting static pressure motion and pressure into motion is a simple mechanism as a differential engine, and has a very high output efficiency.
This is an important invention that contributes to energy conservation as a driving engine for reciprocating engines such as presses, lifts, injection molding machines, civil engineering machines, propulsion engines for vehicles and ships, and generators.

Title: Differential engine using the principle of static pressure motion

[Claims]

1. A fluid cylinder, comprising a pressure gear shaft or a pressure roller shaft as an eccentric shaft, a one-way rotation mechanism provided,
The structure is such that the pressing shaft is pressed in the direction of movement by screw tightening, electromagnetic force or the like. Further, a pressing gear, a pressing roller, and the like,
A differential mechanism in which gears, rollers, racks, smooth shafts, etc. are engaged. A differential engine that uses the principle of static pressure motion, which has a structure in which thrust generated on the eccentric side circumference of a pressing gear, roller, etc. is returned to the opposite side circumference.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prime mover. An object of the present invention is to provide a reduced input static pressure differential prime mover.

[0002]

2. Description of the Related Art At present, there is no prime mover that operates with pressure as input, and there is no complete product available.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a low-input fluid power engine in which the input from a pressure source pump is mainly pressure only and the inflow of fluid is minimized. The problem is how to convert the linear thrust into rotary motion without moving the cylinder piston.

[0004]

First, a one-way rotating cam clutch is attached to the rotating shaft of the pressing gear, and the pressing shaft is eccentric to transmit the linear thrust to the rotary motion unit. It is discovered that it is.

Further, a mechanism is used in which the transmitted thrust is output and a part of the thrust is returned to the circumference on the side opposite to the circumference on the pressing side of the pressing gear through the arrangement of racks, gears and the like. We have discovered that the amount of advance of the shaft of the pressure gear and the amount of retreat of the shaft can be the same size. The function of the above two mechanisms keeps the current position rotation without moving the pressurizing gear shaft that has been linearly pressurized. The above is the principle and structure of static pressure motion.

[0006]

[Function] If the pressurizing gear shaft does not move, the stroke of the pressurizing cylinder piston can be made very small, so fluid is not required from the pump and motion is generated by inputting only pressure without requiring inflow. Therefore, extremely A fluid engine with reduced input is established. It is proportional to the output pressure.

[0007]

[Embodiment] Although there are various mechanisms of the embodiment,
As a basic structure, a first embodiment of FIG. 1 will be described. Fig. 1 This is a linear motion engine, in which 13 and 14 rack axes arranged in parallel via gears make relative movement in the right and left 17 and 18 directions.

First, if the hydraulic pump 2 is driven, the pressurizing cylinder 6 is pressurized through the pressurizing circuit 5 to generate thrust in the direction 7. 10 pressurizing gears pressurized through 8 pressurizing shafts, 13 when the pressurizing shaft is at the center,
No motion occurs because the 14 racks are pressurized evenly, but in this embodiment, the thrust is transmitted to the 13 racks in proportion to the eccentricity because the rack is eccentric in the 13 rack side in the embodiment.

The thrust is moved forward in the direction of the rack shaft 13 to which the thrust was transmitted, and then transmitted to the 11 output gear, and the gear 1
The direction of rotation is 6, then the thrust is transmitted to the 14 rack shafts, and the thrust returns to the opposite side of the eccentricity of the 10 pressing gears by the movement of the rack shaft in the 18 direction, and is retracted. Therefore, the gear shaft does not move and continues to rotate at the current position as long as the rack shaft dimensions allow. Output rack axis
Extraction from 11 gears is possible.

[0010] However, it is not possible to use a mechanism that switches in the opposite direction with a one-way cam clutch.
The above is the description of the structure and operation of the first embodiment. If a pressurizing gear and pressurizing cylinder are additionally installed on the structure shown in Fig. 1 and the relative arrangement is used, a mutual pressurizing and cross-returning circuit structure is possible.

A second embodiment shown in FIG. 2 will be described.
The gear arrangement shown in Fig. 2 is the same as that of Fig. 1 except that the rack shafts 13 and 14 are replaced with 11 and 21 gears. The principle of movement is the same, but the feature is that it can rotate continuously indefinitely.

[0012] In addition, 10, 21, 20 gear arrangement, one reference structure of the pressure gear organization. 10 Pressing gear as described, equipped with an eccentric shaft and a one-way cam clutch, 21 is a reciprocating circuit, a supplementary gear that adjusts the rotation direction. This gear is used for regression of 20 gears, but this circuit works to prevent the overrunning of 10 pressure gears.

Also, it is possible to attach a pressurizing cylinder and an eccentric clutch to 20 gears, and use a mutual pressurizing and mutual reciprocating method. If the structure is attached to a single rack shaft, linear motion of the single rack shaft can be generated.

FIG. 3 shows a third embodiment of the present invention, which is a structure of a continuous rotating mechanism of a mutual pressurizing and mutual reciprocating system provided on the inner surface of the internal gear in a position opposite to the pressing gears 10, 11, and 10. FIG.
The one-axis pressurization method is also possible. The above is an explanation of the structure and the principle of movement according to each embodiment.

The addition of a small pump, an accumulator, a dynamo, and a battery makes it possible to use it as an independent engine. In addition, since the pressurizing stroke is very small, it is possible to input pressurizing force such as electromagnetic force via a spring and screw tightening mechanism. It can also be manufactured using rollers, smooth shafts, etc. Also, in the embodiment, the eccentric type of the cam,
Although it is a one-way cam clutch system, it is possible to use an internal gear type eccentric system and a ratchet type one-way rotation system.

According to the principle of the static pressure motion of the present invention, the efficiency of the differential engine is extremely large, and the applications of the static pressure differential motor include reciprocating engines such as presses, lifts, injection molding machines, etc. It is an important invention that contributes to energy saving problems as a propulsion engine for vehicles, ships, etc., and also as a driving engine for generators.

Title: Differential engine using the principle of static pressure motion

[Claims]

A balance is axially mounted on an eccentric shaft such as a crank or a gear, and a counter pressure is applied by a fluid cylinder having both ends of the balance as points of application. Touch the eccentric position of the balance,
A fixed fulcrum is provided, and the balance is made to perform a tilting motion by isostatic pressing of the cylinder, so that a relative movement of the cylinder piston attached thereto is linked. Due to the relative movement of the piston, the circulation of the internal fluid between the cylinders,
A differential engine that uses the principle of static pressure motion consisting of low-pressure and high-pressure multi-stage fluid inputs with a differential mechanism that uses fluid pressure as the main input.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid engine. SUMMARY OF THE INVENTION It is an object of the present invention to provide a low-input fluid motion engine that generates motion by using pressure as input.

[0002]

2. Description of the Related Art At present, there is no differential engine with pressure input.

[0003]

[Problems to be Solved by the Invention] Although the input efficiency of the hydrostatic differential engine is relatively small, ie, 10% of the total volume of the cylinder, it is still another object of the present invention to provide a low-input engine in which the input is 5% or less.

[0004]

SUMMARY OF THE INVENTION In an input type of a differential engine having a fluid pressure as a main input, a low-pressure and high-pressure two-stage pump is installed and a multi-stage pressurizing system is provided with a booster. It is characterized by a structure that amplifies

[0005]

[Function] It is a fluid engine that moves when a fluid of about 1/10 or less of the volume of the fluid cylinder used is used. By using the balance as the point of force and causing the cylinder piston that opposes the thrust to move relative to each other, a circulating flow is generated between the cylinders and the movement continues with only the input of the pressurized pressure. Of course, there is no movement unless there is a difference in propulsion between the cylinders.

[0006] The difference in propulsion force is caused by displacement of the position of the fixed fulcrum contacting the balance. However, the shorter the distance from the fulcrum to the point of application of the stroke of the balance that moves around the soybean, the less it will be. If the momentums of the pistons are not the same, a reciprocating motion having a difference in propulsion force will not be established, so the shape of the fixed fulcrum and the shape of the contact part of the balance are selected, and the fan-shaped motion of the eccentric shaft on which the balance is mounted is The feature is that the stroke is the same while maintaining the difference in propulsion.

When the direction of movement is switched, the pre-pressurizing section must first be depressurized, which is one-tenth of the cylinder volume. It is 1, the remaining 9/10 fluid is kept inside the cylinder by the action of the low pressure one-way valve. Therefore, it is necessary to replenish the 10-1 fluid released at the next start-up in a short time.

Conventional cylinder movement The stroke is moved by injecting the whole volume from the pump, but it has the feature of having a power saving effect that it can be performed with a pump input of about 1/10 in the circulation circuit. However, in a high voltage circuit,
Even a 1/0 input would result in a large load. For example, if two cylinders with a pressure receiving area of 100 square centimeters and a stroke of 1 meter are used, the total volume will be 20 mm.
It is a liter, one tenth or two liters.

Since 2 liters of pump must be injected within 1 second in this engine, a pump input of 2 liters and 50 atm require 20 horsepower. In the present invention, two-stage input is performed, 10 liters of 2 liter seconds are first injected at 5 horsepower, and after about 0.8 seconds, the pump is switched.
If 0 atm 0,3 liters continuous pressure is applied, it is possible with 5 horsepower because the motor is the same. It is clear how high the system is, which saves labor.

[0010]

Embodiment The structure and movement will be described with reference to the embodiment of FIG. 1. The embodiment is a linear reciprocating type differential engine and shows a state during movement in 24 directions. First, if the low pressure pump 2 is driven and the start valve 5 is turned on, the 9 and 10 cylinders are equally pressurized through the 7 pressurizing circuit, and both thrusts are generated in the 22 direction. When the internal fluid is full, turn on the high pressure valve and switch to the high pressure pump.

The pistons of the cylinders 9 and 10, 11
Since both ends of the balance are used as the points of application, they are opposed to each other via the balance and pressed against each other with 15 fixed fulcrums as axes. Since the position of the fixed fulcrum is at one third of the length of the balance, the thrust difference is 2: 1 while the thrust is the same, and it is inclined forward in the direction of 9 propulsion cylinders. In normal balance movement, the smaller the distance to the fulcrum is, the shorter the movement stroke is.However, due to the shape of the fixed fulcrum, the slope structure of the contact part of the balance and the sector movement of the eccentric shaft, the movement is the same stroke. The feature is the point.

[0012] Therefore, the relative movement of the cylinder pistons is 9 and 10, and the internal fluid of 10 is circulated through the circulating circuit of 27. Therefore, the inflow of fluid from the 9 propulsion cylinder pump is not required, It moves by inputting only pressure and rotates 13 gears up to a half turn. It can be said that a low input static pressure exercise engine has been established.

The output shaft 18 has a rack shaft, and a rack 19 has an output gear 25 with a one-way rotating clutch.
To the output shaft. 26 gears with one-way rotation clutch, for output when reversing. When the balance reaches the angle indicated by 16, the valves 4 and 5 are turned off, the valve 6 is turned on, and then the high pressure valve 4 is turned on again, and then the reciprocating movement is started.

The above operation is repeated to continue the exercise cycle. There is a one-second pause time when switching between forward and reverse, and the multiple installation method of the mechanism shown in Fig. 1 is effective for smooth output. Instead of the 13 gear shaft eccentric mechanism,
It is also possible to manufacture a model with an eccentric shaft with a one-way rotation clutch and a continuous rotation output method. It is also possible to use a labor-saving method that releases the decompressed fluid to the prosthetic cylinder.

The static pressure differential engine of the present invention is a simple mechanism, and has extremely excellent input efficiency. Therefore, it is an important invention that contributes to energy conservation as a reciprocating engine for presses, lifts, injection molding machines, civil engineering machines, propulsion engines for vehicles, ships, etc., and a driving motor for generators.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

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

[0003]

[Problems to be Solved by the Invention] The problem with the circulating differential engine is how to efficiently reduce the reverse thrust generated in the discharge cylinder.

[0004]

The thrust direction of the discharge cylinder opposed to the propulsion cylinder is reversed by a gear or the like, and a plurality of installations are reversely propelled by pressurization of a back pressure by the action of a relative pressurizing lever. It is characterized by reduced power.

[0005]

[Function] If the reverse thrust of the discharge cylinder is reduced, FIG.
As shown in the figure, thrust of the propulsion cylinder is generated because the propulsion resistance of the eleven propulsion cylinders disappears. Therefore, the internal fluid of the discharge cylinder, the pressurized cylinder, and the like are circulated when pressurized.

[0006] Since there is no need for the inflow of fluid from the pump, a complete static pressure motion with pressurized pressure as input is established. In other words, it can be said that the principle of static pressure motion was established for the first time by the establishment of this engine.
The exercise and structure will be described with reference to the embodiment of FIG.

[0007]

[Embodiment] An embodiment of the present invention is a linear reciprocating differential engine, and shows a state in which the forward cylinder shown in FIGS. If two pumps are driven first, 9
The pressurizing circuit is pressurized, and the back pressure parts of the discharge cylinders 13 and 14 are equally pressurized. It does not move in a balanced manner because it is supported by 20 balances via 13 and 14 cylinder piston thrust reversing gears.

Next, when the forward valve 5 is turned on and the forward pressure circuit 7 is pressurized, cylinders 11 and 13 are equally pressurized, and thrust is generated in the direction of 22 each. The thrusts of 11 and 13 are opposed through the gear of 19, but the thrust of 13 discharge cylinders is lost due to the back pressure from the constant pressure circuit of 9, so the thrust of 11 thrust cylinders Thrust is generated, and 17 rack axes start to move 24 to the left.

The movement of the thirteen discharge cylinder piston shaft during the forward movement is to the right, so that the internal fluid is flowing through the circulating circuit of 26 and the volume of the propulsion cylinder is equal to 11 so that the fluid flows in from the pump. Continuous propulsion exercise that does not require.

[0010] The relative movement of the back pressure portions of the discharge cylinders 13 and 14 at the time of forward movement due to the action of the balance of the balance 25 results in mutual recirculation of an equal volume, and the forward movement without the need for fluid inflow from the pump. Lasts. Therefore, a differential motion with the main input of the pressurized pressure is established.

When the vehicle reaches the forward terminal, the position is detected by a limit switch, etc., the circuit 7 is depressurized, and the circuit 8 in FIG. 1 is pressurized. . When reaching the retreat terminal, the circuit of 8 is depressurized and the forward movement is started by pressurizing the circuit of 7 again, and the cycle is continued by repeating the above procedure.

By the alternating movement of the rack shafts of the output shafts 17 and 18, it is taken out as a rotating motion by 21 one-way rotating cam clutch. Also, it is effective to use a low pressure cylinder as the back pressure part. Explanation of principle and structure. In addition, a manufacturing method in which a gear, a crank, and the like are used as a point of application of a piston is also possible. The cylinder stroke and volume can be selected. Speed control is possible by adjusting the flow rate of the circulation circuit. In addition, a small pump, accumulator, dynamo, battery, etc., can be used as an independent engine.

The differential pressure engine according to the present invention is a simple mechanism, and the input efficiency is ten times that of a conventional hydraulic engine, so that it can be used in a variety of applications, such as presses, lifts, injection molding machines, and civil engineering machines. It is an important invention that contributes to energy conservation and the environment as a driving engine for reciprocating engines such as vehicles, propulsion engines for vehicles and ships, and generators.
