[The detailed explanation of the invention] [The purpose of invention]

[The scope of technology of invention and/or the basis of the technology]

This invention is to use Rotary Pump to transit liquid or vapour through pipe under pressure. As there is more detailed explanation, a piston to move guiding home combined with a rotor with the function of cylinder which enables the exercise of going and returning on a straight line. The rotor with the function of cylinder is installed in the center of the inside part and concentric circle. The case cover is fully equipped with a piston controlling pin installed with partial disposition in the inside part of a circular shape enables the movement of going and returning. This structure can have excellent effect on fluid transfer, ensuring a smooth operation and improving endurance. Because of the simplification of the structure, it can reduce production cost and make a light and shape. It can expand the scope of application.

There are many sorts of original rotary pumps. Vane Pump has many portions with sliding movement of going and returning and Rotary Gear Pump has a structure for movement from the inside gear to the outside one.

but, original vane pumps reduce the rotation to prevent changes of the portions by the pressure of fluid. Due to the reduction of rotation, the efficiency of transit will be lowered and endurance will be weakened with noise and oscillation caused by the friction between the certain portion and the case.

Also, when the action of entering on gear happens, Rotary Gear Pump bring about Under Cut which penetrates into the ending in one gear and goes out of gear on the opposite side. Such a Under Cut reduces the life of gears and makes loud noise and serious oscillation. Among the above pumps, the rotation

with high speed complicates the structure and induces frequent breakdown and trouble because of the light and handy shape.

[Technology subject to be achieved though the invention] The invention is to solve problems with the original pumps. The purpose of the invention is to offer pump with the excellent transferring effect of fluid, improved endurance through smoothing operation, reduction of production cost and the simplification of structure with light and handy shape. For that, this invention presents the cylinder block installed enables the rotation inside the case and in a concentric circle.

Also, this invention presents structure of a piston with movement guiding home to making the rotation after the installation of parts for rotation, and at the same time, the movement of going and returning in the above cylinder block.

Also, this invention presents a piston controlling pin leading partial disposition in the inside part with a circular shape making possible the movement of going and returning of the piston at state by moving guiding home.

Also, this invention presents the means of the regulation of the position of partial disposition making it possible to change the positions of the partial disposition of piston controlling pin controlling the amount of the transit of fluid.

Also, this invention presents the composition by connecting the control from one side or two sides with the piston controlling pin. it is possible to make of the change of speed without be noticed.

[The composition and/or operation of invention]

The case has an inhalation hole and a sending hole in the opposite position. A cylinder block is installed for rotation in its inside part with a circular shape. The cylinder block is installed by sliding in the above cylinder block and a piston is fully equipped moving guiding home. This piston is combined with the above cylinder block. When the cylinder block is rotated, the piston combined with the cylinder block fixed in the case cover for partial disposition with the axis rotation with the movement of going and returning on a straight line.

Drawing 1 showing parts of Article 1 of this invention, The inside part with a case in a circular shape has an inhalation hole and a sending hole in the opposite position. It is composed of a piston and a cylinder block installed to make the rotation by the axis of rotation. The inside part of the above cylinder block is fully equipped for moving guiding home. The piston installed sliding in a closed circle. The piston guides home to the part in the opposite direction. The above moving guiding home is made by inserting the piston controlling pin to installed in the case cover at the state of partial disposition. When the cylinder block is rotated, the movement of the piston going returning on a straight line and the rotation along moving guiding part at the same time.

As shown in drawing 4, the cylinder block located in parallel with the inhalation hole and/or the sending. The piston entirely moves one side of the cylinder block to the inside part with the piston in a circular shape. The piston controlling pin is inserted in the middle site to moving guiding home. At the state before rotation, that is, when the angle of rotation is o °, and when the cylinder block is rotated 45 ° in a right direction around the axis, the piston controlling pin makes the partial disposition in upper axis. As shown in the drawing, the piston moves to the middle part of the cylinder block occupying the space inhalation fluid.

In the progress of rotation, when the cylinder block is rotate to 90 °, a right angle appears with the inhalation hole, the sending hole correctly moving into the middle part of the cylinder block much more space of inhalation than 45 in rotation is occupied

When the piston is rotated to 135 °, it passes by the middle part of the cylinder block and gradually move to another side and can occupy much more moving space. When it is rotated to 180 °, the cylinder block returns to the same initial position, 0 ° and completes the process of inhalation, and at the same time, the piston moves in maximum to the another side of the cylinder block and occupies the biggest inhalation space of fluid.

The process of the exhaustion of fluid begins at this state. When the piston is rotated to 225 °, it begins the action of exhaustion. When the piston moves into the middle point of the cylinder block, it gradually exhausts much more fluid, when the angle of rotation becomes 270 °, the cylinder block is located at the right angle with the inhalation hole and/or the sending hole. When the piston correctly moves to the central point, it makes even more exhaust.

When it is rotated to 315 °, the piston passes the central point of the cylinder block and gradually move to another side stage, the action of the exhaust of fluid going to an end, at the same time, such a process gradually occupies the inhalation space in maximum. When it is rotated to 360 °, the piston return to the initial position of 0 ° , it retains the biggest amount of the inhalation of fluid. After then, piston repeats the process of the above process with the action of pumping.

Drawing 5, showing the parts of Article 2 of this invention, The Article 1 and/or Article 2 moving guiding part to the opposite side on a straight line is equipped opposite to each other in a cylinder block. The piston to has a moving guiding ball which operates with the composition operated at the same time. Briefly speaking, the composition of parts of Article 1 makes two pistons in opposite direction, and Article 1 and/or Article 2 piston act individually.

The fixed piston of Article 1 is combined with moving guiding part to state which inserts the fixed piston controlling pin in the cover of case with each moving guiding ball in like shown in drawing 6. With the assumption that the angle of the rotation is 0 °, Article 1 piston operates under the same order as shown in Article 1 in drawing 4. Article 2 piston operates in the same order with piston located at the state of 90 ° as shown in drawing 4. Article 1 and/or Article 2 piston have different starting points of operating but the processes of action are accomplished similarly. Because detailed operating process of each rotating angle can be comprehended through the process of operation in drawing 4, more detailed explanation is omitted.

Drawing 7 shows the separated parts of Article 3 of this invention,

The moving guiding part with a circular shape penetrates into the cylinder block. The piston in a circular shape gets into the exercise of going and returning along the side of cylinder block. The fixed piston controlling pin fixed to the cover of case to moving guiding home and the condition of partial disposition between the axis of cylinder block and the piston controlling pin is the same as shown Article 1 and/or Article 2. In Article 1 and/or Article 2, the piston touches the cylinder block in a way different from the way in which the two mentioned parts touch in the Article 3, with a three-D touching state. The action of the piston is simultaneously progressed with together with the action of Article 1 in drawing 4.

In the above Article 3 acting example, the operation is easy because of the feature of structure ensuring high precision in process and perfectly preventing fluid from leaking and taking under high pressure.

In the composition of this invention, there is no motive power and the compelled supply of fluid and the rotation around are made by the movement of the piston.

Drawing 8 and drawing 9 in the composition of the invention have no motive power at the axis of the rotation. Instead of that, it supply of fluid through the inhalation hole around the axis of rotation is made by the movement of the piston which acts as the motive power of fluid rotation around the axis of rotation under the pressure of the fluid.

Drawing 10, shows Article 4, acting example of this invention, This is to show the means of the regulation of the position of partial disposition by controlling the position of the partial disposition of piston controlling pin. Except for the difference in the composition of the cover of the case and the piston controlling pin, another structure can selectively adopt voluntary acting example of Article 1 ~3 acting examples. In the drawing, it adopted Article 1 acting example

The variable piston controlling pins are fully equipped with a female screw pipe to install enabling ascent and descent within the box to control the positions of partial disposition and the means to control the positions of partial disposition to fit into a male screw in the upper of the box to control the positions of partial disposition. This structure is suitable for variable pump. According to the direction of the rotation of male screw, the variable piston controlling pin by the translation of screw can ascend and descend inside the box to control the positions of partial disposition. If it is close to the center of the axis of rotation, the inhalation space of fluid is reduced and the amount of exhausting is diminished because the length of the movement of going and returning is shortened. On the contrary, if it is far from the center of the axis of rotation, the inhalation space of fluid is increased and the amount of exhausting can be increased because the length of the movement of going and returning is lengthened.

As Article 5, acting example, in drawing 11 to combine variable pumps installed for the controlling of the position of partial disposition as shown in drawing 10 with pumps without the means to control the position of partial disposition in the opposite direction like Article 1, Article 2, and Article 3, acting example in the drawings. Left pump to have the means to control the position of partial disposition is connected with variable pumps to increase power from the outside around the axis of rotation to transit fluid. The right pump without the means to control the position of partial disposition is composed of motorioil motor) to rotate passively by the movement fluid. The means to control the position of partial disposition can be make possible by controlling variable pumps.

The inhalation holes of variable pumps are connected with the oil exhausting hole of oil motor by the connecting pipe. At the same time, the oil sending holes of variable pumps connect the oil inputting hole of oil motor. Inside the pump for transmitting fluid, there is a closed circle ensuring the circulation without loss of fluid and the change of speed without being noticed. Under the power of rotation around the axis of rotation of variable pumps, fluid flows out of the oil sending hole in the indicated direction, flows into the entrance hole of oil motor, and then fluid is transmitted along the cylinder block of oil motor around the axis circle the movement of which leads to the rotation. The function of oil motor is rotated around the axis using the stream of fluid. The above composition is assumed that the amount of fluid through a one rotation reaches l.OOOcc. When variable piston controlling pin to the center of the axis of rotation of variable pump, transmitting amount of fluid is diminished under 500cc through one rotation, and then the amount will be reduced in half. On the contrary, speed is increased because of the transit amount of fluid is relatively increased when variable piston controlling pins enable more partial disposition than piston controlling pin of oil motor. Then the position of variable piston controlling pins are regulated without being noticed. Finally, it can regulate the speed of rotation of oil motor.

If the variable piston controlling pins of pump are controlled with variable shape opposite direction around the centre of axis of rotation, which can reverse the direction of fluid.

Drawing 12 is supposed to change the structure in drawing 11. It are equipped with variable oil motors having the same structure as the variable pumps installed the means to control the positions of partial disposition instead of oil motor which is changable in the state to maintain the pump with variable shapes in the structure in drawing 11. As to the means to control the positions of partial disposition, variable piston controlling pins freely control the positions. Compared with the structure of oil motor which is unable to change positions, this invention can subdivide the scope of the change of speed. The means to control the positions of partial disposition adopted in the structure in drawings 10, 11, 12 with a structure to ascend and descend piston controlling pins use the translation of female and male screw but this is not defined in the appendent drawing. Within the scope of technological ideas, there are various replacements and changes, for example, rack is installed in the piston controlling pin and it is controlled with a piston, and cable is installed in the piston controlling pin and controlled by a lever connected to it.

[The effect of invention]

Because the above invention can have various changes in composition, it can achieve the excellent effect of transit of fluid and extension of utilization. It can control the amount of transit of fluid and correspond to the various conditions of transit and smooth operation. It can improve endurance and reduce the cost of production with a light and handy shape.
