A plurality of vane slots 21 are arranged on the rotor 18, and the opposing side of each vane slot 21 external port is the cylndrical surface, and the axis of cylndrical surface is 22, and the proximal ends of vane slot 21 is a cavity 23, and cavity 23 is wideer than vane slot 21, thereby can be arranged in the rotor so that slide plate can insert.When the many groups of employing slide plate, the cavity of a plurality of correspondences can be set, and be inserted in the compression slide plate of one group of slide plate in the same cavity and the both sides that the acting slide plate is separately positioned on supporting post, as shown in Figure 4.There are circular arc corner 66, seal groove 11 and seal ring 51 in rotor 18 bi-side, and a plurality of pressure spring 61 that is located in the seal groove 11, and seal ring 51 is fastened in the seal groove 11, and under the promotion of pressure spring 61, is tightly connected with inboard wall of cylinder block.
Bow type slide block 26 is set, the arc surface of bow type slide block 26 and the cylndrical surface coaxial line 22 of the vane slot 21 on the rotor 18 respectively between the relative cylndrical surface of the bi-side of each slide plate and vane slot 21.In the middle of each slide plate proximal ends is the oblique concave surface 27 of V-type, and the oblique concave surface 27 of V-type is wideer than supporting post 56, thereby when slide plate during at vane slot 21 intrinsic deflections, the oblique concave surface 27 of V-type can play the effect of stepping down, and avoids bumping with supporting post 56.Each slide plate proximal ends both sides has the guide runner of outstanding slide plate body respectively, also is slidingly matched with it in the compression guide chute 16 that the compression guide runner 28 of each compression slide plate 24 inserts on the cylinder end piece 7; Also be slidingly matched with it in the acting guide chute 17 that the acting guide runner 281 of each acting slide plate 25 inserts on the cylinder end piece 7.
Wherein, described guide runner the 28, the 281st is formed by connecting with suitable cambered surface and two semicylinders of guide chute smoothly by two, and the axis of semicylinder is 29 (seeing Fig. 7,8).The compression guide runner 28 of compression slide plate 24 is thicker shorter; The acting guide runner 281 of acting slide plate 25 is thin longer.Understandable, the width of compression guide chute, acting guide chute, compression guide runner and acting guide runner and thickness etc. can design adjustment according to actual needs.Slide plate 24,25 outer end radial surfaces are processed into the cambered surface that compression chamber internal surface axle center is consistent and shape is suitable with the groundwork arc of cylinder block 4,5.Radial and axial end face at slide plate 24,25 has U type Stamping Steel Ribbon 31 to be contained in the slide plate seal groove 52, the 53rd, spring, circular arc corner 30 and end clasp 60 (seeing Fig. 6,8) are arranged on the U type Stamping Steel Ribbon 31, thereby Stamping Steel Ribbon 31 can be limited in the described seal groove 52 by end clasp 60; And form arc surface between the circular arc corner 59 of the circular arc corner 66 on circular arc corner 30, the rotor 18 and cylinder block circular arc corner 65, U type seal ring 14 and cooperate, improved the sealability between cylinder block and the angle of rotor, reduce wear.
The lower end, both sides of described seal ring is provided with the top and opens the inclined-plane, and guide runner is provided with described top with the position that described slide plate joins and opens the identical inclined-plane of inclined-plane gradient.Fig. 6 exemplifies the compression guide runner 28 and guide chute enlarged view of a compression slide plate 24, and the contact condition of guide runner and U type seal ring is described.When slide plate rotates to U type connection cylinder body 6 positions, inclined-plane 42 above the guide runner opens inclined-plane 46 with the top, lower end of U type seal ring 14 and is slidingly matched, and with U type seal ring 14 upward, foreign side's ejection opens, U type seal ring 14 is held back among the cylinder block, and fair with the cylinder inner wall face, can reduce bump and wearing and tearing between U type Stamping Steel Ribbon 31, the seal ring 14.Equally, the outer rim of compression guide chute 16 and acting guide chute 17 is processed into inclined-plane with inclined-plane 46 same slope, makes guide chute cooperate slip better with the inclined-plane 42 of guide runner.The 43rd, the camber chute of compression guide runner 28 outer side surfaces of compression slide plate 24.
One group of slide plate working principle of Fig. 2 a, b, c explanation internal-combustion engine.The similar quartastroke engine working principle of the present invention, each group slide plate has air-breathing, compression, expansion, four strokes of exhaust in a work cycle.When one group of slide plate rotated to compression (air-breathing) chamber 19, the done work guiding of guide chute 17 of the acting guide runner 281 of the acting of front end (exhaust) slide plate 25 was retracted in the vane slot 21 of rotor 18 and does not work; 40,3,40 rotations (seeing Fig. 5 b) around the axle center are successively stretched out in compression guide runner 28 guiding of guide chute 16 by compression of the compression of rear end (air-breathing) slide plate 24 from rotor 18, make compression (air-breathing) slide plate 24 radial end faces be close to the 5 inwall work of therapeutic method to keep the adverse qi flowing downward cylinder body.The front of compression (air-breathing) slide plate 24 is a compression stroke, and compressed inflammable gas is stored between U type seal ring 14 and the compression slide plate 24, and pressure constantly raises; The compression chamber of the back of compression (air-breathing) slide plate 24 is a suction stroke, gets ready for the one group of slide plate work in back and (sees Fig. 2 a).
When acting slide plate 25 turns over U type connection cylinder body 6 places, because its guide runner 281 slides along acting guide chute 17, acting slide plate 25 begins to stretch out from rotor 18, making its radial end face be close to the cylinder block inwall slides, between acting slide plate 25 and compression slide plate 24, form a Seal cage, high pressure mixed gas moves forward (seeing Fig. 2 b) with this Seal cage, when compression (air-breathing) slide plate 24 forwards U type seal ring 14 positions to, the spark plug 9 igniting compressed mixed gas (or oil injecting nozzle injected fuel) of igniting, make in the acting chamber of combustion gas between U type seal ring 14 and acting slide plate 25 and expand, promote acting slide plate 25 outputting powers, drive the internal-combustion engine rotation.Simultaneously, compression guide chute 16 guiding compression slide plates 24 are withdrawn in the rotor 18 does not work, and acting slide plate 25 is also released cylinder body (seeing Fig. 2 c) with the remainder of exhaust gas that the one group of slide plate work in front produces.When acting slide plate 25 turned over relief opening 8, working stroke finished, and combustion gas is discharged by relief opening 8, finished the one action circulation of one group of slide plate.
Fig. 4 is the structural representation of the internal-combustion engine of a kind of two groups of slide plates of the present invention.The internal-combustion engine of this structure, the working stroke that whenever rotated a circle twice, and have the sealing complementarity between every group of slide plate, reduce gas leakage.Certainly, can as required the structural type of three groups of slide plates or more groups of slide plates be set.
According to working principle of the present invention and structure as seen: adjust the distance between compression, the acting vane slot 21, can change the compression ratio of internal-combustion engine; Change the shape and the size of compression, acting chamber camber line, can change the compression ratio and the discharge capacity of internal-combustion engine; Can not establish the inlet and outlet valve, reduce other number of components.
The camber line of Fig. 5 a explanation cylinder block and guide chute is created into principle.The 1st, the central shaft of rotor 18 and oblate type cylinder block, the guide chute of oblate type part is formed by connecting smoothly by 4 sections similar respectively circular arcs on the internal surface of cylinder block and the cylinder end piece 7, and every section arc section of cylinder block becomes same axis with the corresponding arc section of guide chute on the end cap 7.See that Fig. 5 a exemplifies arc and creates, oblate long axis direction arc section 41 of cylinder block and guide chute arc section 32 have common axis 3; Oblate short-axis direction arc section 34 of cylinder block and guide chute arc section 35 have common axis 40; Semicircle segmental arc 37 and rotor 18 have common axis line 1.The 33rd, arc section 41 and 34 point of contact, the 57th, arc section 32 and 35 point of contact, the 36th, the point of contact of semicircle segmental arc 37 and arc section 35.Because of the big oblate shape of cylinder block similar with the little oblate shape of guide chute, distance must equate between the corresponding large and small arc section, so slide plate is because the control of guide chute, the radial end face of slide plate keeps small equidistant rotation with inboard wall of cylinder block in compression chamber, only by Stamping Steel Ribbon 31 contact cylinder body slipper seals, make the contact stress of having avoided centrifugal force to produce between slide plate and the cylinder body, beat and rush down leakage, reduce wear, improve sealing effect.The axis of arc section 54 is 1, and the joint point of contact of the arc section of it and oblate cylinder body minor axis is 55, and arc section 54 keeps small equidistant sealing with rotor 18, strengthens the isolation effect between compression chamber 19 and the acting chamber 20.
Fig. 5 b exemplifies the rotary motion trace of an acting slide plate, and the working procedure of slide plate is described.During the compression chamber 19 of acting slide plate 25 on the left sides, because the axis of the semicircle segmental arc 37 of acting guide chute 17 outer rims is 1, semicircle segmental arc 37 is 36 with the point of contact of arc section 35, and the slide plate 25 that does work this moment is retracted in the vane slot 21 of rotor 18 and does not work; After the guide runner 281 of acting slide plate 25 turns over point of contact 36; continuation is slided along the track of arc section 35 and 32, and acting slide plate 25 stretches out from rotor 18, and the radial end face of acting slide plate 25 is close to arc section 34; rotate to arc section 41 again, make acting slide plate 25 proper functioning in acting chamber 20.
Fig. 5 b also exemplifies the process that a slide plate changes rotation center.During rotor 18 rotation,, cause the inner of acting slide plate 25 under the effect of guide runner 281, can depart from the axis 1 of rotor 18 because the guide runner 281 of acting slide plate 25 slides among inserting acting guide chutes 17.Because of rotor 18 different with the axis of arc section 35,32, the proximal ends of slide plate 25 of causing doing work is that swing in the axle center with 22 in cavity 23, according to: the perpendicular bisector of any 2 lines passes the principle in this circular arc center of circle on the circular arc, and the perpendicular bisector 38 of two semicolumn axle center 29 lines 39 of guide runner 281 (also being the center line of slide plate) must pass the axis of this section guide chute arc section.See Fig. 5 b, guide runner 281 is when semicircle segmental arc 37 positions, and the center line 38 of slide plate passes axis 1; When guide runner 281 rotated to guide chute arc section 35 positions of short-axis direction, the center line 38 of slide plate passed axis 40; When guide runner 281 rotated to guide chute arc section 32 positions of long axis direction, the center line 38 of slide plate passed axis 3, and slide plate radial seal circular arc end face 64 this moment and arc section 41 same axis 3.
So, though rotor 18 is around axis 1 rotation (see figure 2), and the compression slide plate 24 above it in compression chamber 19 when cylinder body major axis arc work, be around axis 2 rotations; Acting slide plate 25 during along cylinder body major axis arc section 41 work, is to rotate around axis 3 in acting chamber 20.If the radial surface of slide plate is processed into arc surface consistent with cylinder long axis direction inner surface of cylinder block axle center and that shape is suitable, just can make slide plate keep face contact seal, significantly reduce wearing and tearing and leakage at the groundwork arc and the cylinder block inwall of active chamber.
Fig. 7 a, b are the guide runner 281 cut process schematic diagrams of acting slide plate 25.Acting slide plate 25 is around axis 1 rotation in compression chamber 19, and contracts and do not work in rotor 18.Forward the position of U type seal ring 14 to when the guide runner 281 of acting slide plate 25, and (see figure 6) when opening inclined-plane 46 is pushed up in close its lower end, because the incision angle of acting slide plate 25 is bigger, guide runner 281 top ahead of time opens U type seal ring 14, causes gas to rush down leakage easily and (sees Fig. 7 a).Therefore, the front ends above acting slide plate 25 guide runners 281 are made into the plane of inclination 44 of suitable gradient, make guide runner 281 postpone the top and open U type seal ring 14, acting slide plate 25 just can be with less angle contact with through U type seal ring 14, and minimizing gas rushes down leakage.
Fig. 8 is the guide pad working condition figure on the end cap.Compression slide plate 24 stretches out work from rotor 18 in compression (air-breathing) chamber 19, when finishing compression (air-breathing) stroke, after rotating to oblate cylinder body minor axis location, because compression the guide chute 16 more shallow and broads on the end cap 7, be subjected to centrifugal force and The Effect of Inertia Force, compression slide plate 24 slides to long axis direction easily, makes the edge of its guide runner 28 collision guide chutes.Therefore, the side of the compression guide chute 16 on cylinder end piece 7, be that the place, end of the semicircle segmental arc in the center of circle is provided with a guide pad 45 with axis 1, when guide pad 45 inserts in camber chute 43 (see figure 6)s of compressing slide plate 24 guide runners 28 outer side surfaces, to guide guide runner 28 to continue to rotate, and compression slide plate 24 will be retracted in the rotor 18 not work along compression guide chute 16.
Fig. 9 is the audio-visual picture of one group of slide plate of internal-combustion engine.
