【発明の詳細な説明】
本発明はロータリエンジン、具体的にはロータ
が単一の摺動部を有するロータリエンジンに関す
るものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rotary engine, and more particularly to a rotary engine in which the rotor has a single sliding portion.
ロータリエンジンは往復運動する部分がないの
でレシプロエンジンに比べ、運動が滑らかで機械
的損失が小さく、又ロータのつり合わせが容易で
あつてエンジンの振動が非常に小さいと言う長所
を有するので、今日までに種々の型式のロータリ
エンジンが研究されてきた。 Since rotary engines do not have any reciprocating parts, they have the advantage of smoother motion and lower mechanical loss than reciprocating engines, as well as easy rotor balancing and very low engine vibration. Up to now, various types of rotary engines have been studied.
ところが現在実用化され市販されているバンケ
ル形ロータリエンジンは、吸気孔および排気孔の
開閉時期がオーバラツプすることから、ロータ摺
動部がそれ等の位置に達した時に作動室相互間の
連通が生じ、その故に、燃焼が不安定であつた
り、吸気孔および排気孔の開口時間が短かく、開
口時間に対する自由度が小さいなどの問題を有す
る。更に未燃混合気を吸気する際に、吸気行程に
おける作動室に既燃ガスが侵入して燃焼が悪化す
ることにより、排気ガス中に多量のHCが含まれ
ると言う欠点がある。 However, in the Wankel type rotary engines currently in practical use and on the market, the opening and closing timings of the intake and exhaust holes overlap, so when the rotor sliding parts reach these positions, communication between the working chambers occurs. Therefore, there are problems such as unstable combustion, a short opening time of the intake hole and the exhaust hole, and a small degree of freedom regarding the opening time. Furthermore, when an unburned air-fuel mixture is taken in, burnt gas enters the working chamber during the intake stroke and combustion deteriorates, resulting in a large amount of HC being contained in the exhaust gas.

信頼性に欠ける上、高速回転するロータの運動に

させることが困難であると言う欠点がある。 On the other hand, unlike the above-mentioned rotary engine, there is an engine in which the axis of rotation of the rotor and the axis of the rotor housing coincide with each other, and the rotor completely rotates. This type of rotary engine has a rotor that rotates more smoothly than the previously mentioned types of engines. In this rotary engine, one of the plurality of spaces formed between the rotor having a plurality of sliding parts and the rotor housing is divided by two vanes. These vanes consist of a first vane used for intake and compression of the air-fuel mixture, and a second vane used for expanding combustion gas and exhausting burnt gas. However, each of these vanes must be in airtight contact with the rotor once per rotation of the rotor, and the drive device that reciprocates these vanes in the radial direction of the rotor housing is attached to the body of the vane. A side hole is provided, a lock piece is built into this side hole via a spring, a lock hole is provided in the wall of the vane chamber into which this lock piece can be inserted, and a plunger is placed outside the vane chamber and biased by a spring. By inserting the vane into this lock hole, it is structured to give the vane a predetermined movement. Therefore, the structure is complicated and unreliable, and there are disadvantages in that it is difficult to bring the two vanes into airtight contact with the outer periphery of the rotor in accordance with the movement of the rotor rotating at high speed.
更に上述した各ロータリエンジンはロータが１

る。 Furthermore, each rotary engine mentioned above has one rotor.
Since the explosion occurs once per rotation, the expansion energy of the working gas cannot be utilized effectively, resulting in poor fuel efficiency.
本発明の目的は、これ等の問題を解決し、単一

ロータリエンジンを提供するにある。 The object of the present invention is to solve these problems and provide a rotary engine with a simple structure and a rotor having a single sliding part.

を特徴とする。 To achieve this objective, the rotary engine of the present invention opens an intake hole in the combustion chamber formed in the rotor housing, and air-tightly injects the air-fuel mixture into the space between the rotor housing and the rotor having a single sliding part. A compression auxiliary member that is held in place is placed on the rotational side of the rotor with respect to the combustion chamber, and an operating member that makes airtight contact with the rotor and prevents combustion gas from entering the combustion chamber is placed between the combustion chamber and the exhaust hole. A sealing member for sealing the combustion chamber is provided in a single sliding portion of the rotor that is arranged and in close contact with the inner surface of the rotor housing, and the drive device has a cam that drives the compression auxiliary member and the operating member. .

により行なう。 FIG. 1 shows the structure of the present invention. A rotor 3 is fixed to a rotating shaft 2 disposed coaxially with the axis of a rotor housing 1. This rotor has a single sliding part and rotates around the axis of the rotor housing 1. Note that a seal member 5 for sealing the combustion chamber 4 formed in the rotor housing 1 is provided on this sliding portion. An intake hole is opened in the combustion chamber 4, and opening and closing are controlled by an intake valve 6. On the other hand, in order to guide combustion gas outward, an exhaust hole is arranged on the side of the combustion chamber 4 opposite to the intake hole, and its opening and closing are controlled by an exhaust valve 7. A compression auxiliary member 8 that reciprocates in the radial direction of the rotor housing and compresses the air-fuel mixture by coming into airtight contact with the rotor is disposed on the rotor rotational direction side with respect to the combustion chamber 4. Also, an operating member 9 is arranged between the exhaust hole and the combustion chamber 4, which contacts the rotor in an airtight manner and prevents combustion gases from entering the combustion chamber 4. Note that the operating member 9
The direction of movement of the compression auxiliary member 8 is also in the radial direction of the rotor housing 1. Further, the compression assisting member 8 and the operating member 9 are moved by a drive device equipped with a cam.

Figure 2 shows the inhalation process. The driving device presses the operating member 9 inward in the radial direction of the rotor housing to bring it into airtight contact with the rotor 3, and the intake valve 6
Open it and inhale the mixture through the intake hole. When the rotor rotates in the direction indicated by the arrow in the figure, the space formed between the rotor housing 1 and the rotor 3 is filled with air-fuel mixture, as shown in FIG. This is the suction stroke. When the rotor rotates once, the drive device presses the compression auxiliary member 8 radially inward of the rotor housing 1 into airtight contact with the rotor 3 and moves the operating member 9 radially outward. As a result, the rotor housing 1, the rotor 3, and the seal member 5
The air-fuel mixture trapped in the space between the compressor and the compression assisting member 8 is gradually compressed as the rotor rotates.
Note that another space formed between the rotor housing 1 and the rotor 3 communicates with the outside air via a passage formed in the compression auxiliary member 8. When the compression process is completed, the compressed air-fuel mixture in the combustion chamber is ignited using a spark plug or the like. Meanwhile, the drive device brings the actuating member 9 into airtight contact with the rotor 3 again and moves the compression assisting member 8 outwards. In addition, open the exhaust hole and guide the sucked outside air to the outside. This situation is shown in FIG. The exploding and expanding combustion gas causes the rotor 3 to rotate in the direction shown by the arrow, completing the expansion stroke shown in FIGS. 6 and 7. Next, we move on to the exhaust process,
This step is carried out in conjunction with the suction step, as is apparent in FIG. In other words, the rotary engine of the present invention performs four strokes (intake, compression, expansion, and exhaust) in one stroke.
It is a cycle engine, during which one explosion is repeated every three revolutions of the rotor. In addition, the rotary engine of the present invention connects the rotating shaft directly to the output shaft,
Alternatively, they can be connected indirectly and do not require a phase gear like a so-called Wankel rotary engine.

る。 The rotary engine of the present invention having the configuration detailed above uses a rotor that has one part that slides on the rotor housing, so by changing the shape of the rotor, the space formed between the rotor housing and the rotor can be reduced. The degree of freedom in selecting the volume is greater than in other engines, that is, the degree of freedom in selecting the (surface area/volume) ratio of the space as the working chamber is greater.
Furthermore, since each cycle of suction, compression, expansion, and exhaust only needs to be performed once every three rotations of the rotor, the rotary engine of the present invention, which has an intake valve and an exhaust valve, can open the intake and exhaust holes for a long time compared to conventional rotary engines. Since it can be kept open reliably, intake and exhaust are reliable. At the same time, the working gas can be expanded sufficiently, and since the rotor's rotational axis is eccentric to the rotor axis, the working gas can move around the rotor more easily than in a rotary engine where the rotor's rotational axis is installed coaxially with the rotor. It becomes possible to rotate effectively. Therefore, it can be said to be a strong and large torque engine. Moreover, it is only necessary to operate the compression auxiliary member and the operating member once every three rotations of the rotor.
The operating time for each member can be freely selected, allowing each member to operate reliably, and the drive device with a simple structure using a cam allows each member to be reliably driven. becomes.
