Abstract

PURPOSE:To continue a rotary motion by generating differential thrust force at a uniform pressure of a rotor vane to decrease an inflow amount of fluid. CONSTITUTION:A motor 1 is started to rotate a pump 2. Next, when a solenoid valve 13 is turned on, pressure oil passes through a rotary valve 17 from a pressure circuit 7 and through a Y-shaped circulative circuit 30 of each rotor 5 to fill cylinders 9, 11, 12 with the pressure oil. An ineffective thrust vane 16 generates no thrust because of both side pressures, and an effective thrust vane 15 generates thrust because of one side pressure, to perform rotation in a predetermined direction. Then, a slide table 24 of a cylinder 6 is moved in a right direction by action of an eccentric cam crank 28, to move a slide table of a cylinder 32 in a left direction. Volume of the cylinders 11, 12 is contracted to be associated with moving in right/left directions of both the cylinders 6, 32, and since oil passes through the circulative circuit 30 to fill the cylinder 9 with the oil, a rotary motion without necessity of an inflow of fluid from a pressure source is realized. In this way, an inflow amount of the fluid is decreased, and the rotary motion can be continued.

Description

Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a hydraulic fluid engine. The purpose is to provide a low input fluid prime mover.

[0002]

BACKGROUND OF THE INVENTION The present invention belongs to the field of new fluid technology which has not been commercialized at present but has a main input of pressurizing pressure.

[0003]

There is a point in which the differential pressurization force is generated by the equal pressurization of the rotor vanes, the inflow amount of the fluid is reduced, and the rotary motion is continued.

[0004]

[Means for Solving the Problems] First, by moving the cylinder outer cylinder back and forth while rotating the rotor, static pressure was changed to dynamic pressure, and the inflow of fluid from the pressure source was reduced. .. The Y-shaped pressure circulation circuit enables continuous pressure rotation.

Further, by installing a plurality of cylinders, the effective lifting vanes are arranged opposite to each other to improve the output. The vane rotation angle was eliminated by changing the relative placement angle of the vanes.

Next, the problem was solved by attaching a weight balancer to the outer cylinder of the cylinder to reduce the load consumed for the reciprocating motion.

[0007]

[Example] Fig. 1 is a schematic structural diagram of an example. The action and motion will be explained with reference to Fig. 1, first, start the motor of 1 and rotate the pump of 2, then turn on the solenoid valve of 13.
If it is set to 7, the pressure circuit of 7 passes through 17 rotary valves, and the Y-shaped circulation circuit of 30 of each rotor passes 9, 11, 1
The hydraulic pressure fills the second cylinder.

The vane 16 does not generate a vertical force due to the pressure on both sides, and the vane 15 generates a vertical force due to the pressure on one side and rotates in the direction indicated by 23. The slide table of 24 cylinders of 6 cylinders moves to the right, and the slide table of 32 cylinders moves to the left.

In conjunction with the left and right movement of both cylinders, the cylinder volumes of 11 and 12 are reduced, and the cylinder of 9 is filled by passing through the circulation circuit of 30. A rotary motion that does not require inflow is established.

The horizontal movement of the slide table was required to target the 15 effective lifting vanes of both cylinders. Furthermore, the reason why the arrangement angle of the vanes of both cylinders is changed is that when the rotor vane angle comes to a position perpendicular to the direction of movement of the table, it becomes a resting angle where no vertical force is generated, and therefore it rotates with respect to each other. Is the change needed to replenish each other.

From FIG. 2 on page 2 of the drawing, the display from FIG. 5 shows the state of the cylinder of 6 every 90 degrees.
The problem in the position of FIG. 3 and FIG.
It means that the pressurized circulation port of is connected.

Therefore, it is possible to solve the problem by moving the arrangement angle of the 16 vanes slightly clockwise and arranging the positions of the pressurizing port and the exhaust port to be 180 degrees opposite to each other. Check valve 3 is not required. It is also possible to attach a pressure stop cam valve, etc. inside the rotor.

Therefore, a small amount of leaking liquid and almost only air are discharged from the exhaust port of 8, and a rotary motor with liquid pressure as the main input is established.

The output is proportional to the difference between the normal drop force applied to the pressure receiving area of 15 and the reverse drop force applied to the circular surface of the rotor, and further to the pressurizing pressure and the flow rate of 30 times. Any fluid can be used as long as it is a liquid with a low compression rate such as water or oil. Relative movement is also possible with the machine copying method. It is also effective to use hydraulic pressure to pressurize the vane spring.

[0015]

Since the present invention uses the liquid pressure as the main input,
Because very little energy input is required to generate liquid pressure. Furthermore, because the output is not proportional to the discharge amount of liquid, it is an important key to contribute to future energy problems as a power-saving fluid prime mover.
