In the improved rotary piston (B) of the present invention, the rotary piston filed by the inventors of the piston (B) whether the shaft pin (4) is preceded and the tail roller (88) is followed by the rotary or compressed rotary engine. Regardless of whether the tail roller 88 is preceded and the shaft pin 4 is followed by the engine, the resistance of the piston B due to the rotational operation according to the rotational direction of the rotary piston B (hereinafter referred to as the piston B) is satisfied. Lubrication and cooling according to the present invention, and reinforcement of the bearing force received by the tail roller 88, and the clearance between the wall of the tail and the wall of the operating chamber 44, together with the pressure of the gas or fluid, the centrifugal force, and the fine movement of the shaft pin 4. There is an appropriate seal 102 because of this.

In the rotary engine, the interval between the left and right seals 102 and 105 of the direction line in which the piston B rotates is always constant. However, without considering the effect of the gas pressure on the piston (B), if the shaft pin (4) side is preceded and the tail roller 88 is followed, the tail roller 88 is operated by the resistance of the guide (D) 44 ) Wall surface and the side of the tail roller 88 is in close contact with the space becomes narrow, sealed and lubricated. If the tail roller 88 is preceded and the shaft pin 4 portion with the rotatable space follows, the clearance is generated on the distal wall of the piston B of the preceding tail roller 88 and the wall of the operation chamber 44. The gap between the seals should be extended to block, seal and lubricate the interspace. As a whole, there is a problem regarding the flow of lubricating oil in the space portion of the housing A in which the guide table D with respect to the rotation of the piston B is located.

Therefore, the lubricating oil is supplied to the lubricating oil chamber 105 by placing a passage 90 penetrated on the surface of the lubricating oil supply chamber 105 in the direction of the rotational axis 2, and the lubricating oil is applied while the guide D and the piston B are rubbed. It should flow smoothly, cool the piston (B) and reduce its weight.

The engine is a piston (B), the direction of the intake and exhaust hole 46 and the order arrangement of the intake port 10 and the exhaust port 12 of the housing (A) is different, whether the piston shaft pin (4) or the tail roller 88 is preceded. When the shaft pin 4 is preceded without affecting the fruit thread 102, the tail roller 88 portion of the piston B is the outer diameter of the tail roller 88 and the inner garden space surface of the rotating body C. By coincidence it may be necessary to reinforce the strength to support the pressure in the operating chamber 44 since it is the longest part of the piston B length. The piston B is a reinforcing wall 89 for the supporting portion of the tail roller 88 to withstand gas pressure. The outer diameter of the tail roller 88 is rotated when the piston tail roller 88 is top dead center of the operation chamber 44. Since it satisfies that it is on the inner line of (C), the piston (B) of the tail roller (88) side contacting the wall of the operating chamber (44) within the range not disturbed by the operation of the tail roller (88) integrally with the piston (B). The wall surface of the tail roller 88 portion of the piston B is operated in the wall surface of the operating chamber 44 which is made thicker than the rotation line of the outer diameter of the tail roller 88 drawn by the piston B. The reinforcing surface (89) is made to face the wall surface of 44 and to rotate.

If the tail roller 88 is preceded, the gas or lubricant entering the concave front surface 59 between the tail roller 88 and the shaft pin 4 between the tail portion of the piston and the tail roller 88 behind the rotating surface around the shaft pin 4. In order to discharge the flow path 90, the flow path 90 is also applied to the rotating body C to reduce the resistance, and evenly the pressure in the space of the housing A in accordance with the movement of the tail roller 88 that follows the guide table D. However, if necessary, make a hole in the upper plate of the rotating body (C) and the housing cabinet. Lubricate between the shaft pin (4) and the rotor (C) and let it drain back. The backing of the piston B is effective for lubricating the friction surface between the rotating parts. Of course, it is also possible to make a flow path formed as a groove in the guide (D).

A plurality of flow paths 90 are formed on the front surface 59 of the piston B so as to be connected to the front and rear left and right surfaces and the lubricating oil chamber 105 and also connected to the tail roller 88 side. The flow path 90 as a whole is out of the lubricating oil chamber 105 position and is on the rotation shaft 2 side.

In order to reduce the weight of the piston B, it is possible to smooth the cooling of the piston B by forming a space that becomes the flow path 90 within a range that is not subjected to the support force for supporting the movement and resistance.

The thread 102 inserted into the thread groove 110-1 of the piston B is a rectangular thread 102 that is bent as a whole, and four 'base' type seal plates 103 are inserted into the thread groove by inserting the seal 102 more than two times. It is configured so that the ends of the non-rectangular chamber 103 do not overlap each other.

When the spring 108 is inserted into the curved square seal groove 110 of the piston B, and the four air-mounted seal plates 103 are fitted to each other by inserting two end portions thereof, two threads 102 are formed.

Ends of the air-operated chamber 103 are uneven in the shape of 'ri' and are inserted into each other to form a flat plate, and the spring 108 and the air-operated chamber in the thread grooves 110-1 of the piston B having a rectangular shape ( When 103 is inserted in sequence and piston B in operating chamber 44 is inserted, the seal 102 in thread groove 110-1 is formed by spring 108 on the wall surface of operating chamber 44 of rotating body C. Close contact.

The spring 108 pushes the square plate 103 in all directions so that the four base plate 103 closely adheres to the wall of the operation chamber 44, so that the 'ditch' or 'meet' between the ends of the base plate 103 is achieved. Although the space of the mold is formed, the position of the contact portion, which is the disconnection part of the air-mounted seal plate 103 constituting each layer, does not coincide with each other, and the 'dip' type space formed at the center side of the piston B of the seal 102 is a seal groove ( The operating chamber 44, which is a portion which fills gas and a portion where lubricant flows, which is a space between the piston B and the wall surface of the operation chamber 44, by inserting the seal 102 into two or more layers with the inner depth of 110-1). ) Are isolated and isolated from each other to seal the operating chamber 44. It goes without saying that the portion of the housing A or the rotating body C to be sealed by bolts or the like is sealed by using the gasket 114 so that no gas or lubricant is leaked between them.

In order for the lubricant 102 to stably supply the wall 102 of the seal 102 and the operation chamber 44, there is a flow path in the shaft pin 4, and the position of the seal oil supply chamber 105 is the seal 102 of the piston B. Is connected to the flow path (90) so that the position of the rotation axis (2) than.

Lubricating oil supply chamber 105 is made in the above-described form, but more than one layer 105, the oil film grooves 120 in the middle of the circumference to form an oil film along the wall in contact with the wall of the operation chamber 44, and several connections It supplies the lubricant to the wall surface of the operation chamber 44 by inserting a spiral spring 123 which pushes out in all directions by forming a space that is a spiral groove 122 on the back side of the bottom of the thread groove 110-2, which throws out the ball 121. do. The spiral spring 123 has a rectangular shape, and an annular connecting ring angularly connects the spiral spring 123 to an angled portion.

The support wall of the piston (B), the tail roller 88 is stably supported by the guide (D) and lubricated the part in contact with the wall surface of the operating chamber 44 by the lubricating oil supplied from the shaft pin (4) (44) can be commercialized by supplying a rotary piston (B) to seal the gas, prevent mixing with the gas, and reduce weight and lubrication through the passage (90) of the piston (B).
