SPACIOUS PISTON MECHANISM THAT HAS A ROTATING PISTON STRUCTURE.

Field of the Invention This invention relates to a spacious piston mechanism having a rotating piston structure.

BACKGROUND OF THE INVENTION In a field relating to a spacious piston machine, which has a reversible relationship with internal combustion engines, such as a pump, a blower, a compressor and the like, a rotary mechanism has already been used. pallets that has a rotating piston structure. For example, in the case of a rotary blower as shown in Figure 8, the blades (5) are arranged in an inclined manner so as to move flexibly in radial grooves (4) of a rotor (3) provided in a portion of circular space (2) of a quadrangular box (1). Then, the air and / or other fluid is pushed out from a suction hole and into an exhaust hole by the influence of the blades (5) moving flexibly in the slots (4) of the rotor (3), rotating to high speed and pressure increased by the centrifugal force within the circular portion of space (2). Originally there is a difficulty and contradictory technical problems for a mechanism of rotary vane type like the one mentioned above, which is impossible to execute at the same time as a fatal factor that comes from a composition that must divide a space being able to change its capacity when a palette (blade 5) is pushed to a cam ring (a circular portion of space 2). Because it must be achieved at the same time by the complete improvement of some serious problems, such as the wear on one edge of a pallet, an additional composition opportunely to push and operate a pallet mechanism and obtaining a uniform and hermetic operation in condition to obtain a seal, which was very difficult to improve in the prior art. Currently, it seems that a useful effect through the use of said mechanism is restricted because the serious problems mentioned above are solved by only a tactical device, which is not a drastic means to solve the problems of the prior art. In consideration of the current situation mentioned above, this invention was conceived in order to improve technical problems completely and strategically. What this invention intends is to provide a mechanism that has a new structure, which does not depend on only the edges of a pallet to change the capacity. Thus, a new technical mechanism was drastically achieved by this invention.

SUMMARY OF THE INVENTION The inconvenient technical problems of the prior art can easily and completely be improved by a spacious piston mechanism having a rotating piston structure as shown below. A new mechanism in this invention comprises: • A small integrated rotor with a main shaft and inclined against a large cylinder-type rotor to support a bearing pillar; • Inclined sliding grooves made in frontal sites and equally divided spaces between said large rotor and the small rotor; • Pallets that have a certain angle adapted on said slots as if they were bridges; and • A suction hole and an exhaust hole provided in positions on side struts. In this invention, since both the large rotor and the small rotor rotate at the same time through the bridge-type curved blades, at a point of equilibrium, the change of capacity is carried out by the movement of said blades in the sliding grooves without deteriorating the uniformity of rotation and seal effect. Accordingly, this invention can completely improve one of the most difficult points in the traditional mechanism, which strongly forces the vane edges projecting in a cantilevered manner. A real example of how this invention is explained using Figures 1 and 2, is as follows: A small rotor (7) integrated with a main shaft (6) is arranged inclined against a large rotor (8) to form a ring-shaped cylinder. Said large rotor (8) is surrounded by a bearing pillar (9). In this case, of course, the small rotor (7) and the large rotor (8) are arranged in the space between the side posts (10) and (11 ') which are fixed by bolts. A pair of slidable and inclined grooves (12, 13, etc.) are provided in confronting positions where the small rotor (7) and the large rotor (8) are opposed to each other, and paddles (14) which they are properly bent and tightly located in the positions between said grooves (12) and (13) precisely as bridges. In this way, such a unique rotating mechanism in which the large rotor (8) rotates together with the small rotor (7) through the bent vanes (14) constantly seeking a point of balance is conceived. In this rotary mechanism, the divided spaces (15, etc.) are formed by said bent vanes (14), and these spaces can change their capacities according to the rotation of the rotors. At the same time, the vanes (14) only move in the slots (12) and (13). Consequently, the same result to modify the capacity was completely effected using the aforementioned method in this invention, although it was different with respect to the traditional rotary vane-type mechanism, in which the change of capacity was achieved by pushing and moving edges of vanes that they are projected in a cantilever fashion, in a fixed cam ring. Figures 3 to 5 that are mentioned below show how the mechanism of this invention is achieved. In Figure 3 it is shown that "O" is a center point of a small circle of a radius "r" and "O '" is a center point of a large circle of a radius (1). The two radios "OA" and "O'B" roll keeping parallel.

When the spokes "OA" and "O'B" are kept parallel in an optional return position, a drawing of them is made as follows: When drawing a straight line "AC" forming a constant angle "a" against a radius "OA" through an "A" point of the "OA" radius, said "a" angle becomes an acute angle back to the right. As the next step, when a straight line "BC" is drawn forming an acute angle "ß" against a radius "O'B" through a point "B" of the radius "O'B", said angle "ß" it becomes an acute angle back to the left. In case a crossing point of two straight lines "AC" and "BC" becomes "C", a crossing angle becomes V. In the aforementioned Figures, ZCDA = ZCBE = ß, because OA // O'B. In the case of? CAD, ZCAD = a ZCDA = ß ACD = K, ZCAD + ZCDA + ZACD = a + ß + K = 180 °,? = 180 ° - (a + ß), therefore, K also becomes at a constant angle because both a and ß are constant angles. What is mentioned below is an explanation of the basis of the Figure 4. In the case that the three angles, a, ß and K are prepared in advance under the condition that 0o < < 90 °, 0o < ß < 90 °, a + ß + K = 180 °, based on this condition the following is made up. After establishing a tilt amount "O'O" in time, a small circle of a "OA" radius and a large circle of a "O'B" radius are plotted. At an optional return point of said "OA" radius, when a straight line "AC" is drawn forming an "a" angle against said "OA" radius through a "A" point, the "a" angle is made as a right turn angle. After placing a point "F" in a timely position on the straight line "AC", when drawing a straight line "FG" forming an angle "K" against the straight line "AC" through the point "F", angle "K" is made as a right turn angle. Moreover, after putting a point "G" in a timely position on the straight line "FG", when drawing a straight line "GH" forming an angle "ß" against the straight line "FG" through the point " G ", the angle" ß "is made as a right turn angle. Finally, a parallel "O'B" radius is drawn against the straight line "GH" and a straight line "BC" parallel to the straight line "FG". From the aforementioned explanation, the following expression can be clearly derived: ZACD = ZHCI = ZHFG = K, ZCBE = ZCIH = ZFGH = ß, because FG // CI and GH // O'B Consequently, ZCAD = ZCBE = ZACD = a + ß + K = 180 °. In? CAD, ZCAD + ZCDA + ZACD = 180 ° Therefore, ZCDA = ZCBE. Finally, the radios "OA" and "O'B" become parallel because they are OD // O'B. Based on Figure 4, it is possible to make the following mechanism. By joining the straight lines "HC" and "IC", a bent line "HCI" is formed. When this bent "HCI" line is referred to as a thin bar, it becomes a bent "HCI" bar with an inclined angle "K". In case a small circle of an "OA" radius is considered to be a plate in the form of a small circle (a), a thin slot corresponding to a line segment "AH" is formed on said small plate Circle (a). In the event that a circle of radio O'B '"is supposed to be a plate in the form of a large circle (b), a large circle of a radius" O'B "is made as a line drawn on said plate in the form of a large circle (b) A ring-shaped plate (c) having a width of the difference between the spokes "O'B" and "O'B '" is made, and the thickness of said plate in the form of a ring (c) is equivalent to the thickness of the plate in the form of a small circle (a) A thin groove corresponding to a line segment "Bl" is formed on said ring-shaped plate (c). in the form of a ring (c) is just placed on the plate in the form of a large circle (b) and is completely fixed there on top of (b).

The bent bar, the plate in the form of a large circle (b) and the plate in the form of a small circle (a) having the aforementioned figures are combined as follows: Assuming that an inclined portion of the small circle (a) and the large circle (b) from the center of a main axis is "O'O", the plate in the form of a small circle (a) can be placed on the plate in the form of a large circle (b). In this case, the plate in the form of a large circle (b) rotates about a point (O '), and the plate in the form of a small circle (a) rotates around an "O" point. The aforementioned folded bar "HCI" can freely move in the thin slots of the plate in the form of a small circle (a) and the ring-shaped plate (c) when said bar is put into said grooves. The rotating energy of the plate in the form of a small circle (a) causes the plate in the form of a large circle (b) to rotate through the bent bar "HCl" as a transporting medium when the plate in the form of a small circle ( a) it is spun by energy. Then, the radius "O'B" traced on the plate in the form of a large circle (b) rotates keeping parallel to the "OA" radius of the small circle on the plate in the form of a small circle (a). This means that both of the circular plates (a) and (b) can rotate at the same angle and at the same speed. This movement is achieved even if the inclined portion of "OO" was changed. A method for providing a width to the folded line "HCI" is described using Figure 5 as follows: First, a bent line "HCl" is drawn in an optional "return" position of the "OA" radius of a small-shaped plate circle (a) using a, ß and K with the following condition; 0o < a < 90 °, 0o < ß < 90 °, a + ß + K = 180 °. This is carried out by the same method to prepare the drawings of the folded line "HCl" already mentioned. In this figure, a ratio of the radius "OA" of the plate in the form of a small circle (a) and the radius "O'B" of the plate in the form of a large circle (b) that are corresponding to said bent line " HCl "become parallel.

Second, an "AJ" string having a certain length is traced through a crossing point "A" between the folded line "HCl" and the plate in the form of a small circle (a). The radius "OJ" through a point "J" is plotted. A central angle "e" is fixed against the string "AJ". "O'K" is drawn in parallel with the "OJ" radio. A "BK" string through a "K" point is drawn. A central angle "p" is fixed against the "BK" string. Through a "J" point, a straight line "JP" is drawn parallel to a straight line "AH". Additionally, through a "K" point, a straight line "KQ" is drawn parallel to a straight line "Cl". A crossing point "L" between the straight lines "JP" and "KQ" is fixed. A doubled line "PLQ" was drawn which was combined by two straight lines "PL" and "LQ". From the aforementioned figure the following question can be proved. In the case of ZBO'K and ZAOJ, since the edges of "OA" and "O'B" and other edges of "OJ" and "O'K" are parallel in the same direction, it has to be ZBO'K = ZAOJ p = e. Therefore, the following mathematical expression can be formed since two isosceles triangles "BO'K" and "AOJ" are similar figures.

Mathematical Expression 1 is O 'B 1 BK = = r- AJ = - AJ OA r Since the length of the string "AJ" is fixed, the length of the other string "BK" is also naturally fixed. Therefore, in the folded lines "HCl" and "PLQ" the edges "HC" and "PL" are parallel in a certain space, and also the other edges "IC" and "QL" are parallel in a certain space. In addition, it is possible to make the following strokes. When a vertical segment "AM" is drawn against a straight line "CH" through a point "A", a segment length "AM" becomes "h". Also when a vertical segment "BN" is drawn against a straight line "Cl" through point "B", a length of segment "BN" becomes "d".

From the previous strokes the following mathematical expression is tested. Mathematical Expression 2: ZJAM = ZOAJ - ZOAM = ZOAJ - (ZHAM - ZHAO) = - (180 ° - e) - (90 ° - a) = a • ZKBN = ZRBN - ZRBK = ZRBN - (ZO'BK - ZO'BR) = 90 ° -. { - (180 ° P) "ß.}. = ß + f = ß + f AJ = 2 OA sin - = 2 r sin - 2 2 BK = 2 s B sin - = 21 sin - 2 2 £ g SS h = AJ eos ZJAM = 2 r sen - eos (a - -) = r 2 eos ( a - -) sin - 2 vl 'l' 2 ssesr. { sin (a - - + -) - sin (a - - - -)} = r. { sen a - sen (a - e)} d = BK eos ZKBN = 2 1 sen - eos (ß + -) 1 2 eos (ß + -) sin - 1. { sin (ß + +) - sin (ß + -)} = 1 { sin (ß + e) - sin ß} Therefore, "h" and "d" become a certain length. When the folded lines "HCI" and "PLQ" are joined together with "AM" and "BN" segments, it is possible to say that this is a figure that adds the width of "h" and "d" to the bent line "HCl." Therefore, when a certain width and thickness is given to the folded line "HCl", said line can be converted into a folded pallet. In this way, the rotary mechanism already mentioned using Figures 1 and 2 is objectively tested.

It is possible to conceive the mechanism in this invention as a spacious piston mechanism having a rotary piston structure, establishing a suction port (16) and an exhaust port (17) in the appropriate positions of side posts (10) and ( 10 ') for applicable use, which was shown in Figures 1 and 2.

The actual examples in this invention are described as follows. Based on the method of Figures 1 and 2 mentioned above, a suction port (16) and an exhaust port (17) are arranged, for example, as for a pump. After dividing the outer circumference of the small rotor (7) into n pieces (in this case, a value of n is set appropriately), the sliding slots (12, etc.) are provided in the "h" space in each equally divided position.

These grooves have an angle of inclination "a" against a radius "r" passing through said equally divided positions. As the next step, after dividing the inner circumference of the large rotor (8) into n pieces, the sliding slots (13, etc.) are formed in space "d" in each equally divided position. These grooves (13, etc.) have an angle of inclination "ß" against a radius "I" passing through said equally divided positions. According to the aforementioned means, the folded pallet (14) is joined within these grooves. Each constant angle in the Figures is as follows. Under the condition that a = 32 °, ß = 43 °, k = 105 ° and e = 8o, since the ring-shaped space between a large rotor (8) and a small rotor (7) is divided by n parts of the folded pallets (14), n pieces of the divided spaces (15, etc.) are formed. When the small rotor (7) that was joined with two main axes (6) of this machine rotates to the left, said small rotor causes the large rotor (8) to turn to the left by means of the bent vanes (14) as the medium . At the same time, n pieces of the divided spaces (15, etc.) are turned to the left. The capacity of each divided space (15) increases and decreases once when said space turns to the left once. The fluid is sucked from a suction hole (16) into the divided space (15) when the capacity in said space increases. On the contrary, the fluid in the divided space (15) is sent out from an exhaust hole (17) when the capacity in said space decreases. This movement is the same as in a pump. In this case, the amount of fluid leakage can be increased and decreased by changing the degree of inclination of the small rotor (7) and the large rotor (8) Figure 6 shows a use for a bent vane engine. As shown in Figure 1 with respect to a vane pump, it is easily accomplished by modifying an exhaust port (17) of fluid to a tributary orifice (18) and a fluid suction port (16) to an effluent orifice (19) A new machinery device can be made by combining the aforementioned modified rotating structure with a device 22 which raises liquid under high pressure. The high pressure fluid raised from said device is continuously supplied from a tributary orifice (18) within the divided space (15 ') of the bent vane pump, modified. The fluid flowing within the divided space (15 ') provides pressure to the bent paddle (14'). This pressure towards the bent blade causes the main shaft (6 ') to turn to the right, and then the divided space (15) turns to the right. The fluid in the divided space (15) is sent out from the effluent orifice (19) when the divided space (15 ') is transmitted rotating towards said effluent orifice (19). Therefore, it is demonstrated that this mechanism can work as a rotary fluid pressure motor. Furthermore, what is mentioned below is a practical example for the application of a bent vane motor already mentioned. As shown in Figure 7, in said bent vane motor, a small effluent hole (20) is provided to obtain heated gas in place of a fluid effluent orifice (18). The position to establish said effluent hole (20) is placed in a position where the capacity begins to increase when said divided space (15 ') turns to the left. An effluent port (19) of the bent vane motor fluid is converted to a gas exhaust port (21) to send the heated gas out. This improved bent vane engine becomes a bent, heated gas paddle motor. When a device (23) that rises gas at high temperature and pressure is combined with said bent vane motor, of heated gas, after a selection of a certain divided space (15) located in an affluent hole (20) of the heated gas between n pieces of the divided spaces (15, etc.) of a bent vane motor, of heated gas, a movement there is shown as follows.

First, high temperature gas and pressure flowing from a gas lifting device (23) is continuously flowed into the divided space (15 ') located at a position of a tributary hole (20) for the heated gas. The gas at high temperature and pressure that flowed within the divided space (15 ') presses against a pair of bent vanes (14') forming a divided space (15 '). Then, these two bent vanes (14) and (14 ') receive a pressure that pushes each one in the opposite direction. However, a difference of torque occurs against the main shaft (6) because there is a difference in space between these two bent palettes (14) and (14 '). Such a difference in torque causes the main shaft (6) to turn to the right, and then the divided space (15 ') also rotates to the right. Since the capacity of the divided space (15 ') increases in proportion to a torsional movement of said space, the gas at high temperature and pressure flows into said divided space (15'). In this way, both the main shaft (6) and the divided space (15 ') can continue to rotate and move because the pressure of this gas at high temperature and pressure continues until reaching the bent vanes (14'). Then, when the divided space (15 ') passes by rotating through an affluent hole (20), the gas at high temperature and pressure stops the flow into the divided space (15'). After that, the gas at high temperature and pressure that is entering the divided space (15 ') expands adiabatically because the capacity therein increases when said divided space (15') rotates. This is the reason why the main shaft (6) continues to rotate and also the divided space (15 ') rotates and moves because said pressure by the adiabatic expansion continuously provides influence to the bent blade (14'). In addition, when the divided space (15 ') is transmitted to a position of a gas escape hole (21) by reason of the divided space (15') rotating and moving, the gas heated in the divided space (15). ') is sent out from the gas escape hole (21). In the event that another divided space (15 ') arrives at a position of an affluent orifice for the gas after the rotating movement thereof, the aforementioned movement is verified on the basis of a rotating energy towards the main axis (6). ) works continuously. Therefore, this machinery device can work as a heating engine. A mechanism of this invention, as described above, shows the following effects. Improved uniformity during operation and improved tightness is expected, because what is required for the bent pallets to form the divided spaces is only a movement in a basic portion of the bridge in the sliding grooves when the capacity changes.
