Description

Cavity rotary engine

Technical field

Patent cavity rotary engine of the present invention belongs to field of power machinery.

Background technology

Available engine weight is larger, and is moved back and forth in the cylinder using piston, can bring larger vibrations, operation is not Steadily, crank shaft portion stress is complicated, and this engine energy utilization rate is low, and transmission efficiency is low and economical poor, Zhi Nengyou Oil plant produces motive force in gas in-cylinder combustion, it is impossible to provides power using high steam.

The content of the invention

The purpose of patent of the present invention be in order to solve the shortcomings of the prior art and drawback, it is swollen using the volume of working chamber Swollen structure, gases at high pressure are made to be rotated in work intraluminal inflation, promotion expansion plate around main shaft, there is provided power.This engine energy Utilization rate is high, can provide during work it is powerful, efficiently, stable power.

Technical scheme is used by patent of the present invention solves the above problems：Cavity rotary engine, the engine are main Composition includes：Engine, combustion chamber, the part of air compressor 3 composition.The air compressor is driven by main shaft, and air is entered Row compression, forms pressure-air, is transported to by pressure-air breather pipe in combustion chamber.There are air inlet and fuel in combustion chamber Charging aperture, fuel are transported to combustion chamber by conveying pipeline, and the mixed combustion in combustion chamber of oxygen and fuel produces HTHP gas Body.

Engine is the mechanical part for the ability of high pressure gas being converted into power.Its composition is：Cavity wall and end walls A cavity is formed, cavity wall is tubular, and main shaft is connected with end wall by bearing, and main shaft is in the push-jump position of end wall, so main Axle to the distance of cavity wall be uneven, so having axial ray and distal shaft line in cavity wall.Uniformly it is fixed with main shaft a lot Expansion plate, expansion plate, which can be extended, to be shortened, and expansion plate at least two straight panels are formed, and are slided between two straight panels by neck Dynamic connection.One end of expansion plate is fixed on main shaft, and the other end of expansion plate is close to cavity wall slip, referred to as sliding end, expansion plate Sliding end be fixed with circular arc alice, alice is tangent with cavity wall all the time, and expansion plate and cavity wall can guarantee that good sealing. There are lubricating oil and sealant between expansion plate and cavity wall, have lubricating oil and sealant between expansion plate and end wall, in expansion plate Mutual slip straight panel between have lubricating oil and sealant.The adjacent expansion plate of two fans forms a job with cavity wall and end wall Chamber.

When cavity wall is cylindrical shape, the push-jump position of end wall is in the eccentric position of circular end wall, cavity wall axial ray and cavity wall Distal shaft line forms bundle of planes cavity wall and is divided into both sides, and side is active section, and opposite side is exhaust section.Cavity is with combustion chamber through too high Calm the anger connection, be fixed on cavity wall active section in engine epithelium healing, and be in the position neighbouring with axial ray.In exhaust section There are many exhaust outlets, can ensure that exhaust section working chamber communicates with air, ensure that no pressure is poor between the working chamber of exhaust section. The characteristics of this spline structure is the working chamber small volume at cavity wall axial ray, in working chamber to when moving at cavity wall distal shaft line, work Make cavity volume and gradually expand increase.

When cavity wall is oval tubular, the push-jump position of end wall surface is in the center of oval-shaped end wall, so in cavity wall There are two axial rays and two distal shaft lines, so cavity wall has two active sections and two exhaust sections, and on central principal axis pair Claim.

The beneficial effect of patent of the present invention：Dynamical stability is provided, it is not necessary to complicated crank axle, can be by the burning of fuel Carried out from the different places that operate at of engine, powerful power can be provided, efficiency of energy utilization is high, manufacturing process letter Single, manufacturing cost is low, exports the very good control of power.

Brief description of the drawings

Accompanying drawing 1 provides the right pseudosection of chamber rotary engine of the present utility model.

Accompanying drawing 2 provides the overall front view of chamber rotary engine of the present utility model.

The label declaration of smart part in schematic diagram：

In accompanying drawing：(1) working chamber, (2) main shaft, (3) combustion chamber, (4) expansion plate, (5) cavity wall, (6) exhaust outlet, (7) branch Support, (8) constrictor, (9) compressor, (10) pressure-air breather pipe, (11) fuel feed tube, (12) engine, (13) air flue.

Embodiment

The embodiment for turning patent cavity rotary engine to the utility model below in conjunction with the accompanying drawings illustrates：

Enter combustion chamber (3) from fuel feed tube (11) the conveying fuel of engine first and carry out gases at high pressure fully caused by burning Into the working chamber (1) of engine (12), working chamber (1) space in engine (12) between each expansion plate (4) because Gases at high pressure start to expand.The exhaust section of cavity wall (5) has the working chamber (1) between these expansion plates (4) of many exhaust outlets (6) Air pressure is equal with atmospheric pressure, is easy to retract.Again because the air pressure superatmospheric of active section is pressure difference promotes expansion plate (4) to exist Cavity wall (5) internal rotation, expansion plate (4) is fixed with main shaft (2), drives main shaft (2) to rotate when expansion plate (4) rotates, main shaft (2) Rotational band moves reciprocating stretch of constrictor (8) progress and provides power to compressor (9), in order to which compressor (9) passes through air Pressure-air breather pipe (10) is transported to combustion chamber (3) and burnt, and saves more energy.Engine has a support Frame (7) is fixed, to ensure stability that engine behaves.
