Abstract

A rotary pump in which a bearing (2) is arranged between a scroll ring (3) and an eccentric shaft (1) and the shaft (1) rolls by the roller and leverage actions to cause a rotor (5) to scroll. The rotary pump is provided with a separator (8) of a mechanism for piece-insertion into the rotor (5) by reducing the eccentricity, and the clearance between a cylinder (6) and the rotor (5) is 0.1 μm or less. The material is made heat-resistant of ceramics. Therefore, the structure can has only the rotor having none of blades, vanes or springs, and the performance is improved by the high-gastightness and the non-contact, realizing a simple structure and mass production.

[Background technology]

Instead of pumps in high-volume processing,

For pumps.

There are a wide variety of pumps, but there is a defect that efficiency is reduced due to the extremely high resistance due to the high hermetic seal to achieve high airtightness.

In the field of modern internal combustion engines, there are three ways to convert the pressure of an explosion into rotational output.

1) The turbine engine has a leakage loss of 80% or more and the torque is not large.

2) Mazda-type rotary engines (brow-type cylinders and rice ball-type rotors) always have one compression stroke in one stroke (rotation).

A continuous explosion is not possible, resulting in a loss of compression.

That is, it cannot be a direct injection engine.

3) In the piston type (reciprocating), power is generated only during the reciprocating motion of the crank (forward), so it is 1/2 of continuous output.

By the way, in this rotary engine, if the piston's crank output (torque of one rotation X speed rpm) is set equal, the required expansion gas ratio is 1/10, and the output ratio is Is more than twice as different.

In addition, there is almost no pressure leakage loss and continuous rotation output. "Disclosure of Invention J

) High airtightness and low resistance

The ratio of the size (density) of gas and liquid molecules is 800.

Water and oil cannot leak if there is airtightness that does not allow air to leak.

And what pressure to withstand depends on the material and structure.

Therefore, the capacity of the pump is determined by the rotation torque and the rotation speed of the drive motor.

If the gap between the sliding surfaces is less than 0.1 micron, air cannot pass.

Mass production using precision molds, using ceramics with the lowest thermal expansion of the material.

) Innovative gate valve

By reducing the eccentricity to a few millimeters, the internal organs of the engine became possible.

Because the rotor is a frame insertion mechanism, it can be moved in the same way, eliminating the need for panels and vanes, thus simplifying it.

) Drive shaft eccentric bearing with direct cam

The discovery of physical truth is the function of this pairing sphere.

The function of the mouth and the function of the lever are the conversion abilities of shaft energy and circumferential energy, and the rotation of the shaft can be converted into scroll motion of the rotor, thus minimizing the motion loss. Shaft rotation speed r p m = Rotor outer circumference rotation speed r p m

) The size of one rotor diameter is

This is the length of the crank arm and determines the incident angle of the acting force. Moreover, even if the diameter is large, the frequency is fast and does not change.

By these actions, the fluid moves continuously in one direction, so that the energy transfer can be continuous in one direction. The reverse rotation malfunction like reciprocating cannot be performed. Continuous driving force without leakage loss is possible.

[Best mode for carrying out the invention]

With the structure shown in Fig. 1 as one unit,

As shown in FIG. 2, the operation is carried out in a state where multiple shafts are connected to one shaft.

[Industrial applicability]

21 As an energy shift in the 11th century, a direct injection single-injection engine will be used as a non-polluting clean engine that will enable the realization of renewable energy from vegetable oil instead of fossil fuels.

When applied to Kirkuller, conventional batteries are indispensable but useless. When applied to ultra-high water, multi-stage biston pressurization becomes unnecessary and simplifies.
