Definitions

• Invention belongs to field of hydraulically driven mashines. It can be used as a, high rotative moment, motor with possibilities of power multiplications. According to the International Clasification of Inventions, sign is:
• Hydraulically driven motors with vanes are elements of hydraulically driven mashinery and were widely used in all kinds of industry.
• Double acting multiplier of power is composed from the next parts: inner, hidraulically driven, double acting motor which is, at the same time, part for oil distribution; outer, double acting, motor with liquid stator; case of multiplier with lateral plates, which are supports for bearings; elements for sealing; equipments for supply and discharge of oil.
• Inner motor (part for oil distribution) is placed into a body of, outer motor, rotator. It is composed from: stator, with channals for oil suplly and discharge; rotator; lateral plates; two radial and one axial bearings; ring for distance and elements for conections.
• Working part of stator is elliptic cylinder and it is surrounded with cylindrical surface of rotator.
• This space is closed with two lateral plates and devided, into cells, by vanes.
• Four segments of volumes are formed, by that mean, two for oil supply and two for oil discharge. These volumes are placed oposite each other.
• Elliptic cylinder of stator is bored with hole for oil supply and discharge. Size of working volume is minimal.
• This part of multiplier forms a minimum of rotative moment but it distributes oil to outer motor.
• Stator is supported by two radial and one axial bearings.
• Body of the main rotator is made with shaft which is used for power transmision to the other mashines.
• Body of rotator has holes for pressure distributions: from oil in inner motor to oil in outer motor of multiplier.
• Rotator has a cylindrical surface and it is surrounded with elliptic surface of the, main stator, insert. By that mean are formed four parts of volume: two for pressured oil supply and two for oil discharge. Lateral plates covered stator, vanes devides working volume into cells. Oil into working cells, of outer motor, is constantly presented and is not discharge during the work of multiplier.
• the main rotator is supported by two radial bearings and all parts of multiplier are connected, with case of multiplier, by bolts.
• Principle of multiplier works is: oil under a pressure comes, from high pressure oil pump, into the channel for oil supply. This channel is bored into the body of inner motors stator. Oil, from this channel, through the holes in elliptic cylinder comes into working volumes of inner motor.
• the force on vanes is formed under a influence of pressure, and drives the rotator of inner motor to rotate in direction of working volume growing.
• the process of oil filling to be continued to the moment when volume of cell become maximal.
• pressure of oil, from the working volume of inner motor is distributed, through the holes into the body of, outer motor, rotator to oil which form liquid stator.
• the pressure into of these two volumes is equal.
• the pressure, in oil into the volume of outer motor form also the force on vanes of outer motor, and drives it in direction of volume growing.
• Figure 1 shows assembly of multiplier, transversal cross section
• Figure 2 shows assembly of multiplier-longitudinal cross section
• Figure 3 shows assembly of inner motor-longitudinal cross section
• Figure 4 shows assembly of inner motor-transversal cross section
• Figure 5 shows main rotator-longitudinal cross section
• Figure 6 shows main rotator-transversal cross section
• Figure 7, shows insert of stator-transversal cross section
• Figure 8, shows insert of stator.
• This amount of oil is constantly in these volumes and, under the influence of centrifugal force, oil forms liquid stator.
• vanes 7 Under the influence of pressure on surface, of inner motor, vanes 7 forms a force which drives rotator 9, of inner motor, to rotate in direction of working volume growing.
• Discharging of oil becomes by decrease of cells volume (up 90° and 270°) through the openings 4 and 3. Oil from cells of outer motor dosen't discharge because of influence of centrifugal force.
• multiplier consists from the next parts: into the main rotator 15, Fig. 1, Fig. 2, of multiplier is placed inner motor.
• This motor is composed from the next parts: stator 1, rotator 9, lateral plates 5 and 6, vanes 7, channel 2 for oil supply, channel 3 for oil discharge.
• Supply of oil (from high pressure pump) is from the conector 14 and distrubuer 13.
• the main rotator 15, has a channels 17 with vanes and rotator is centricaly placed into the stator 19 with insert 18. All construction is covered by two lateral plates 20 and covers 21. To eliminate vortex, into the oil, two channels 23 are made into the lateral plates 20 and the covers 21, one for oil under a pressure, one for oil without pressure.
• Rotator 15 is supported with two radial 24 and 25 bearings. The whole construction is covered with covers 27 and 28 and by bolts connected with body of stator 19. To bring into a balance a pressure of oil, on the back side of inner 7 and outer 16 vanes, oil fills channel 31. Supply of oil to the channel 31 is from the channel 2, channel 30 and slots into the body of the inner motors stator.
• the stator of inner motor, Fig. 3, is supported by two radial 10 and one axial 11 bearings.
• Fig 4 are bored the channels 4 for, working volume of inner motor, oil supply.
• Fig. 5 Fig 6 are cuted the channels 17, for vanes 16, and channels 22, for pressure distribution.
• Stator of the outer motor is composed from the body and insert of stator.
• Insert 18, Fig 7, has elliptic cylinder. Lateral sides of insert, Fig 8, has channels 29 for pressure distribution. Double acting multiplier of power is designed for easy manufacturing and it can be used in all places when we need a transformation of hydraulic energy to mechanical power, with a possibility of multiplication of power.
