Abstract

A rotary engine having grooves (7) in those inner surfaces of a seal recess (4) in a rotor (11) which are opposed to the side surfaces of an apex seal member (3), and a plurality of elongated rollers (8) rollably housed in these grooves (7). These rollers (8) can be brought into roll-contact with the apex seal member (3) when said member (3) is moved in the radial direction shown by an arrow (14). Accordingly, even when this member (3) is pressed against the inner surface (6b) of the seal recess (4) by a high combustion gas pressure P1, the member (3) is rendered smoothly movable in the radial direction. In order to reliably introduce the gas pressure P1 into a chamber (19) in the seal recess (4), grooves may be formed in the outer circumferential surfaces of the lower rollers, or recesses communicating with the chamber (19) in the seal recess (4) may be formed in the bottom portions of the grooves (7) supporting the rollers (8). A recess (9) extending in the axial direction of the rotor (11) is formed in the apex portion of an arcuate section of a top surface (28) of the apex seal member (3) so as to reduce a force for pressing down the apex seal member (3) toward a bottom surface (15) of the seal recess (4).

Concrete example

FIG. 1 is a diagram showing a cross section of the rotor engine.

First, when the rotor 11 rotates in a planetary manner, various kinds of force acting on the respective axle seal members are generally shown in FIGS. 1, 2, 3 and 4. This will be described with reference to FIG. As shown in FIG. 2 which is an enlarged view of the portion A in FIG. 1, the vacuum seal member 3 is generally formed on the top 2 of the rotor 11. It is attached to the seal groove 4. In the case of the vacuum seal member 3 assembled here, arrows 45 (with pressure P 1 from the working chamber V 1, which is in a high pressure state) According to the gas flow shown in FIG. 2), the side 10 facing the working chamber V1 of the vacuum seal member 3 receives the pressing force U. The other side 12 facing V 2 is strongly pressed against the wall 6 b on the side of the working chamber V 2 of the seal groove 4, so that the The movement in the radial direction indicated by the arrow 14 of the screw member 3 has become very dull and bad.

In addition, ^ 2 indicated by the arrow 13 shown in the figure 2 Li — the sticker member 3 that is located forward in the direction of travel in relation to the turn of the tar 11 The gas indicated by the arrow 60 having the pressure P 1 from the operation ⁵ 'V 1 in which the top surface 28 of the vacuum seal member 3 is in a high pressure state At the same time, it is pressed down toward the bottom 1 of the seal groove 4 by receiving the pressing force in the radial direction inward or in the radial direction indicated by the arrow 14 according to the flow. As described above, according to the gas flow indicated by the arrow 45, the other side βίί12 facing the working chamber V2 has the negative side of the working space 'V2 side of the seal 潢 4.れる：めめため部材め：：：め：：：：：：：：：：：：：：：：：：：：：：：：：：：：. It has been locked because of the problem. Therefore, the contact between the top surface 28 and the sliding surface 1 of the rotor housing 20 can be sufficiently performed, that is, there is a gap in the rush between the top surface 28 and the sliding surface 1. As a result, the gas of the pressure iM blows from the working chamber V1 to the working chamber V2 through the gap. In addition, as shown in FIG. 3, the top seal 28 of the vacuum sealing member 3 is provided on the sliding surface 1 of the data housing 20 (the inner circumference of the rj code). When the top surface 28 moves in parallel while reciprocating in the direction indicated by the arrow 14 with respect to the top surface 28), an arc having the radius a as the amplitude a of the reciprocating motion of the top surface 28. The top surface 28 is formed on the surface. Because of this configuration, the back seal member 3 is configured such that the contact portion G 2 of the top surface 28 with the sliding surface 1 is rotated by the rotor 1. Thus, the entire arc surface of the top surface 28 can be continuously moved to uniformly wear the top surface 28, and as a result, the abrasion resistance of the AXS seal member 3 is improved.

Further, the spring seal portion 3 has a spring disposed between the bottom 5 of the seal member 3 and the bottom surface 15 of the seal groove 4. At 27, a pressing force is applied outward in the radial direction indicated by arrow 14.

Also, as shown in FIG. 4, the rotor 11 is a rotor housing. In the case where the rotating shaft 11 rotates in the direction of the arrow 13 inside the box seal member 3, the rotation speed of the rotor 11 increases as the rotation speed increases. The inertial force of the centrifugal force is applied from the rotation center P of the rotor 11 to the outside in the radial direction 14 (FIG. 5). In addition, the gas pressure in the operation chamber V1 is set to I and the gas in the working chamber V2 is set to P2 (M> P2). Work on the vacuum seal member 3! ? V1 passes through the passage 16 and the chamber 19 formed between the side wall 10a of the vacuum seal member 3 and the wall surface 6a of the seal groove 4 from the V1. Combustion gas pressure or EI compression gas indicated by the arrow 61 transmitted, ie, the gas pressure M in the working chamber V1 immediately after the gas seal member 3 From the rotation center P (FIG. 4) of the rotor 11 applied to the bottom 5 of the rotor to the radially outer side indicated by W 1, each pressing force acts. In the case seal portion 3, the power P 1 of the same gas acts on a large percentage. Here, the force acting on the entire x-seal member 3 is set to F, and further,

Here, the “” PU.V is placed in the gas pressure chamber 1 that has entered the chamber 1D of the τ seal groove 4 through the passage 16, so that the pressure can be reduced. ^ Material arrow Π:

"P1A4" indicates that the gasket M is pressed when the gasket seal portion 3 is pressed against the wall surface on one side of the seal groove 4). The sliding portion is formed by slipping chyle resistance generated between the side surface 12 on one side of the seal portion 3 and the wall surface Gb on the one side.

Also, the bottom 5 of the vacuum seal member 3 and the bottom of the seal groove 4

The pressure introduced into the chamber 19 formed between the inlet and outlet 15 is caused by the following factors: the flow path resistance in the introduction passage, the change in the volume of the introduction passage 16 and the gas P 1 itself. The top curve of the vacuum shell member 3 according to the pressure change of the

It is difficult to obtain a pressure value that can sufficiently press 28 onto sliding surface 1 of rotor housing 20. For this reason, the abbreviations of the child's part 3 are raised to} and 'j to be tightly attached to the sliding surface 1 of the rotor housing 10. P1A3, which keeps the working chamber VI and the working chamber V2¾17 tight, keeps the vacuum shell part 3 in the rotor housing 20 If the frictional force related to the radial movement indicated by arrow 14 of MA i + P2A2 and the axle seal member 3, which is to be removed from the sliding surface ^ P1 A may cause a shortage. In particular, the curvature of the top surface 28 of the γ-pix seal member 3 is large, that is, the i-axis a of the above-mentioned arc K] in the direction of the arrow 1. , F! Kei ^ V〗 is 5 ♦ During the combustion process, the top surface 28 of the vacuum seal member 3 extending forward in the traveling direction corresponding to the rotation of the rotor 11 indicated by the arrow 13 is relatively wide. Combustion gas of low pressure M acts on the area, that is, on the area A1. Therefore, the above-mentioned mosquito P1A3 is smaller than the mosquito acting on the surface 28 of the vacuum seal member 3 represented by P1A1− + Ρ2Λ2.ぁThe reason is that the contact portion 62 of the arc-shaped top surface 28 of the arc seal member 3 with the sliding surface 1 of the arc-shaped sealing member 3 is rotated by the rotation of the rotor 11. Since the apex 63 of the top surface 28 comes close to the apex 63, the height of the combustion gas] ± M acts over a wide area of the top surface 28. That's it. In addition, the sox seal member 3 is a spring that raises the above-mentioned sex member 3 (the lifting member and the lifting member 3). Although it is assumed that it will be lifted toward the outside of the direction indicated by the arrow and rebounded, the top of the gasket seal member represented by P1 + Surface 2iU, which is blocked by the force of friction and // the frictional resistance represented by P1A4 得 can be lifted sufficiently or left in a fixed state A gap is formed in the top surface 28 of the vacuum seal ⁷ > 3 and the sliding surfaces Ί and f ¾ of the mouth housing 20. Therefore, the combustion gas of the low pressure gas P1 The unburned compressed gas pushed by the combustion gas passes through the gap to the next working chamber V3 during the exhaust process, and as a result, the engine There is a risk of lowering output and lowering fuel cost efficiency. Next, wear of the top surface 28 of the vacuum seal member 3 will be described with reference to FIG. Explain.

When the vacuum seal member 3 comes in contact with the sliding surface 1 of the rotor housing 20, that is, when it comes into contact with the inner surface of the The range in which the apex 63 of the top surface 28 of the vacuum sealing member 3 moves with the sliding surface 1 of the rotor housing 20 is short. ] portion of i¾ side other than Π point unit 63 1, 65 a tendency you sliding rather long, Ru § at _t> Me other this, the top surface 2 8 § specs mortal Ichiru邡¾ 3 part ! ^ As shown by the dashed-dotted line 6G in the figure 部分, on both sides other than the vertex 邡 B3: 、 65 65 65 65 65:: 65 65:: 65. Accordingly, the circumference of the arc of the li surface 2 ii gradually increases, and the pressure of the acting t-JJ is applied to the top surface 2G. Ri receiving Ru area Do widely gradually, ing more to § specs mortal seal member 3 Ri Yo the press was lowered Yo U _υ

Based on the above, the following describes the action of the vacuum shell and the member acting on the member and the operation of the member of the vacuum seal on the sword. It should be noted that the head mounted on the rotary engine of the present invention is described in detail below. As described above, it is possible to change various kinds of power acting on the back shell member according to the preferred embodiment of the shell member.

In Fig. 1, U6 and Fig. 7, 1 is the sliding surface of the rotor housing 20, 2 is the top of the rotor 11 and 3 is the top. The seal seal member, 4 is the seal groove, 5 is the bottom of the seal seal member, 6a and 61 are the wall surfaces of the seal groove 4, 8 is the roller, and 30 is the corner seal member. Yes.

As shown in Fig. 5, the rotor 11 does not revolve around the rotation output shaft P, but rotates on the rotor journal 6 7 which is eccentric from the center of the output shaft P. The rotor 11 slides with the vicinity of the vertex 2 of the rotor 11 in contact with the entire surface 1 of the rotor housing 20. Therefore, the working chambers V 1, V 2, and V 3 / for performing the intake, compression combustion, m-expansion, and exhaust work strokes:. The airtight state of each of the working chambers V 1, V 2, V 3 is defined by the top of the □ rotor 11, The gap between the part 2 and the sliding surface of the mouth housing 20 and the gap between the side 32 of the motor 1 1 and the side housing 40 (7) Prevents 1S leaks from leaking

For this reason, as shown in Figs. 6 and 7, each vertex 2 Is provided with a seal groove 4, and an axle seal member 3 is arranged in the seal groove 4, so that a gap is formed between the vicinity of the apex 2 and the slip surface 1. There is no gap between them. When side seal members 68 are provided on the side surfaces 32 on both sides of the rotor 11, the gap between the back seal member 3 and the side seal members 68 during the circumference is increased. When the corner seal member 30 is disposed, a gap is created between the side surface 32 and the side housing 40 so that a gap is not generated between the side surface 32 and the side housing 40. In addition, the operation S \ Μ, V 2, and V 3 are mutually airtight. In addition, the chamber 19 formed between the bottom surface 15 of the seal groove 4 and the bottom portion 5 of the vacuum seal member 3 has a vacuum seal member 3. A spring 27 is disposed on the slide surface 1 so that the spring 27 can be pressed elastically. Further, a concave groove 7 is formed on each of the hard surfaces 6a and 6b of the seals facing the side surface 10 and the side surface 12 of the vacuum seal member 3, respectively. A plurality of rollers 8 are stored in these recesses 7 in a self-moving manner. These numbers ^[ -pager 8 indicate the side faces 10 and 10 while the vacuum seal member 3 moves in the direction indicated by arrow 1/1. Even if each of the side surfaces 12 receives a gas pressure from the work chamber, the side surfaces 10 and 12 can be in rolling contact with each other. The number of rollers 8 to be accommodated in the groove 7 is preferably 2 trees from the results of various tests.

The roller 8 is preferably made of metal material ^ and has a high pressure ^ ^ Gases that are not easily softened and deteriorated even by gas and that do not cause agglutination or chemical change by combustion products are used. I used a pot. Each roller 8 is generally formed in a slender rectangular shape, preferably in the shape of a cylindrical pin having a diameter of 1 to 0.5 mm.

Also, as shown in FIG. 7, the roller 8 has a pair of corners as shown in FIG. 8 in which both ends 69 are arranged at both ends of the rotor 11. It is stored and supported in the recess 70 of the seal member 30. The corner seal member 30 is provided with a groove 33 for accommodating the vacuum seal member 3, and is formed on the side seal member 63 on the outer peripheral surface 72 of the corner seal member 30. I'm in contact. In addition, the end surface 71 of the corner seal member 30 slides while facing the inner surface 73 of the side housing 40. It is located nearby.

Further, the rollers 8 are incorporated into the concave grooves 7 formed on the it surfaces 6 a and 6 b of the seal grooves 4, respectively, so that the back seal member 3 is operated at a high pressure. Even when pressed against the wall surface 6 h by the gas pressure M, the ax seal member 3 is lightly moved in the radial direction indicated by the arrow 14 so that it can be easily rolled and supported. In order to introduce it to the seal 19 on the seal groove 4-] 5: Introduce to I, .3, 9 and Fig. 10 and Fig. M A simple configuration is acceptable.

Immediately, instead of the above-mentioned plurality of rollers 18, a pair of rollers 50 and 51 shown in FIG. 11 in combination are used. . The upper roller 50 has the same shape as the roller 8, and the lower roller 51 is a grooved roller having a groove 52 formed on the outer peripheral surface. It is to be noted that a plurality of grooves 52 may be formed in parallel, or a plurality of spiral grooves may be used.

The upper roller 50 is used when the vacuum sealing member 3 is pressed against the wall 6a on one side of the seal groove 4 by the gas pressure P2. 6a, the roller 50, and the side surface 10 of the back seal member 3 form an airtight part by mutual contact to prevent gas leakage.

The lower sealer 51 is pressed against the シ 1 surface 6 on one side of the seal groove 4 by the gasket M with the gasket seal member 3. When the gas pressure P 1 is to be introduced into the chamber 19 of the seal 4, the gas passage indicated by the arrow 45 through the groove 52 of the rotor 51 In this specific example, the upper and lower rollers 50 and 51 are both a roller 8 and a circular cylinder [i-roller] in this specific example. In the event of a slip, the upper mouth roller 50 is provided with a gap between the roller 50, the concave groove 7 and the side surface 10 of the backing seal part ¾3. , "Ira is left or right The gas passes through the gap created by the approach, but the lower roller 51 is used when the chamber 19 of the seal groove 4 is in a low pressure state. When high-pressure gas entering from the gap of the upper roller 50 acts, the bottom of the concave groove 7 and the side surface 10 of the vacuum seal member 3 come into close contact with each other, so that a gas passage is not formed. I'm afraid.

To this end, a groove 52 is formed on the outer peripheral surface of the lower roller 51 to secure a gas passage.

In this case, the vacuum seal member 3 has the side surfaces 10, 12 rolled and supported by the rollers 50, 51, so that the working chambers are provided on the side surfaces 10, 12. Even if it is strongly suppressed by the gas pressure from the wall 6a, δI) of the seal groove 4, it can move lightly in the radial direction indicated by the arrow 14. Therefore, the vacuum seal member 3 is provided with a gas from a worker via a groove 52 formed on the outer peripheral surface of the collar 51 on the champ 19 of the seal groove 4. The pressure of this gas is reliably pushed up in the radially outward direction as indicated by arrow 14 to ensure that the gas is introduced.

Further, as shown in FIG. 12, the apex 63 of the arc portion of the top surface 28 of the vacuum seal member 3 is located along the direction in which the rotation center axis of the rotor is in the middle. A concave groove 9 is formed, and this concave groove 9 is preferable. In other words, the width 24 is 1/6 1/3 (0.5 1.0 concealed) of the thickness 23 of the vacuum seal member 3 and the depth 25 is 1.0 1.5. Then, the radius a (Fig. 3) of the arc portion of the top surface 28 including the concave groove 9 is set to be larger than that of a general vacuum shell member, and to be approximately 1.5 or more. It is preferable to use

The top surface 28 of the vacuum seal member 3 in which the concave groove 9 is formed is formed on both sides of the vertex 63 in the arc portion, that is, the rounded surface 10a with the concave groove 9 interposed therebetween. And a rounded surface 10b.

Also, when attaching the perforated seal member 3 to the seal groove 4 formed on the rotor 11, the perforated seal member 3 is attached to the perforated seal member 3. A protrusion 位置決め 6 is formed on the bottom 5 to facilitate the positioning of the rotation center axis in the direction in which the rotation axis extends 13.

[I-1-1 11] When rotating inside the mouth-tapering 20, the slip of the box 7 of 7-box seal 3 The angle of oscillating with respect to the surface 1 changes, and immediately, the contact portion ₆₂ between the mouth of the rounded surface 10a and the rounded surface 10b and the sliding surface 1 of the targe housing ₂₀ . The position 1¾ changes. When substitution you ¾, two Tsu rounding surfaces _10a: 1 Ob to _u Koto you contact the exchange ¾ to be the surface 1 of □ COMPUTER c © di in g 20, on are shown in FIG. ₆ U , Sakukei ^ V 1 is in the early stage of combustion e, Kei 5 In the vacuum seal member 3 located in front of the rotor 11 of the i in the rotation direction II, the rounded surface 10 a slides on the sliding surface の of the rotor housing 20. The contact portion 62 comes into contact, and further rotates from this state (the state shown in FIG. 13), and the contact portion 62 moves to the rounded surface 10b.

As described above, since the top surface 2 & of the vacuum seal portion 3 where the high-pressure gas in the working chamber V1 in the combustion and expansion process operates has the concave groove 9, First, the rounded surface 10a and the sliding surface of Li—tar housing 20

In this state, a very narrow area faces the working chamber V1 side where the pressure is high (FIG. 6), and the groove 9 and the rounded surface sandwich the contact portion 62. 10b, etc., goes to the working chamber V2 side where the exhaust process is performed. That is, a high-pressure gas is applied to a narrow area, and a relatively low gas is applied to a relatively wide groove 9 and an area of a rounded surface 1 Oh, respectively.

Further, when the rotor 11 is further rotated as shown in FIG. 13 and the contact portion 62 is located at the rounding Ob beyond the four grooves 9 of the top surface 28, the rounded surface 10a and the concave groove 9 The gas pressure acting on the gasket is relatively low: for this reason, the avex seal member 3 is moved in the opposite direction to the bottom surface 1! I of the seal groove 4. The inward direction toward the inside of the diameter direction indicated by the arrow 14 [pushing down to fl β: is small and can be suppressed. Obedience 16 Applying to the pressure of the gas introduced through 6, acts on the bottom 5 of the gasket member 3 toward the outside in the radial direction indicated by the arrow 14. The pressing force to push in the direction becomes larger than the pressing force to push down, and as a result, the The top surface 28 of the roller member 3 is securely pressed against the sliding surface の of the rotor housing 20 so that the close contact state can be maintained.

In addition, as shown in FIGS. 9 and 13, the chamber 19 of the seal groove 4 is passed through a groove 52 formed on the outer peripheral surface of the roller 51. Instead of the structure in which the gas from the operating room is introduced into Usui, the apex 2 of the rotor 11 is replaced by the structure shown in Figs. 14 and 15. A plurality of π-pillars accommodated in the concave groove 7 in the seal groove 4 of the cylindrical groove similar to the roller shown in the example of the concrete body in FIG. 6 and FIG. The bottom of the concave groove 7 that supports the u-line 8 is inserted through the "> J" and through the channel 19 of the seal 4 A recess 53 is formed, and the gas from the working chamber is surely introduced into the chamber 19 of the seal groove 4 via the recess 5.3. I get it.

Also, instead of the above-described structure of the holiday shown in FIGS. 9 and 13, instead of the above-described structure shown in FIGS. 16 and 17, a plurality of I- The ends 56 on both sides are replaced with the cores shown in FIG. 8 which are hidden corresponding to each end h fi. Each groove 7 is supported by the groove 70 of the seal member 30, and in this state, the concave groove 7 is formed when a gap 57 is formed between the lower roller 8 and the bottom 54 of the concave groove 7. Constitute . That is, the gap 57 is provided over the entire area of the recess 7 in the longitudinal direction of the rotor 11 and is a seal groove.

It leads to the champ 19 of 4. The gas from the working chamber can be reliably introduced into the chamber 19 of the seal groove 4 through the space 57.

As shown in FIGS. 18 and 19, the axle seal member 3 is provided at the apex 63 of the arc portion of the top surface 2δ of the axle seal member 3. In the concave groove 9, a filler 46, which is relatively susceptible to relatively abrasion in sliding with the sliding surface 1 of the rotor housing 20, is embedded. The sealing member 3 of the packing 46 is in contact with the sliding surface 1 so as to be in close contact with the sliding surface 1, and is in contact with the adjacent working chamber, for example, between the working chamber V1 and V2. Airtightness can be secured. The filler 46 is preferably formed of a relatively soft metal-based material.
