[0002] A conventional hydraulic rotary motor is typically manufactured in a way thatvanes project from a rotor and rotate about a central axis of rotation. The motor includes housingwhere the vanes and the housing define a plurality of chambers. The motor typically has a singleinlet for a working medium to enter the plurality of chambers and a single outlet for the workingmedium to exit the plurality of chambers where the torque to rotate the rotor is limited by thesingle pair of inlet and outlet.
[0003] The rotor in the conventional hydraulic rotary motor is designed to move indirections perpendicular to the central axis of rotation. A volume of each of the chambers inrelation to an angular position of the chamber varies as the rotor moves in directionsperpendicular to the central rotation axis during rotation of the rotor. In particular, the volume ofa chamber is at its minimum and the pressure of the working medium in the chamber is atmaximum as the chamber rotates past the inlet. The volume of the chamber increases and thepressure in the chamber decreases as the chamber approaches the outlet. Such a movable rotorinduces uneven pressure loading and thus a severe side load to a shaft supporting the rotor.Additionally, the torque acting on each vane is not consistent during rotation of the rotor.Accordingly, it would be desirable to have a motor that addresses some of the issues describedabove.

[0028] FIG. 3 depicts a perspective view of the multi lobe motor ring 30. An outercircumferential surface 33 of the multi lobe motor ring 30 may include one or more of pairs ofinlet flow groove 31 and outlet flow groove 32. The inlet flow groove 31 may be aligned withthe inlet port 11 of the outer port ring 10 (see FIG. 2) so that the inlet flow groove 31 can receivethe working medium from the inlet port 11. Similarly, the outlet flow groove 32 may be alignedwith the outlet port 12 of the outer port ring 10 (see FIG. 2) so that the medium flowing in theoutlet flow groove 32 may be discharged by way of the outlet port 12.
[0029] The multi lobe motor ring 30 may include a plurality of lobes 36. In one aspect, anumber of the lobes 36 may be 2 or more, preferably, 8 or more.

In one aspect, the inlets 34at the plurality of lobes 36 may be aligned with the inlet flow groove 31 so that each of the inlets34 can receive the working medium from the inlet flow groove 31 and introduce the workingmedium to the corresponding concave working chamber 38. Similarly, the outlets 35 at theplurality of lobes 36 may be aligned with the outlet flow groove 32 so that the outlet flow groove32 can receive the working medium exiting the concave working chambers 38 by way of theoutlets 35. Due to the continuous medium flow loop among the outer port ring 10, the multi lobemotor ring 30, and the chambers 38, the rotary medium power motor 100 may produce highertorque compared to a conventional hydraulic motor.
[0031] FIG. 4 depicts a perspective view of a vane 40. The vane 40 may include one ormore subvanes 41, 42. In one aspect, the vane 40 may be split into a pair of subvanes, first 41and second 42 subvanes where the pair of first 41 and second 42 subvanes can slide with respectto each other while remaining, in part, in contact with each other.

The round shapes 441, 442 of the vane 40 may be in contact with the innercircumferential surface of the multi lobe motor ring 30 (see FIG. 1), thereby forming a sealbetween the vane 40 and the inner circumferential surface of the multi lobe motor ring 30 duringrotation of the inner rotor 50 (see FIG. 1). The round shapes 441, 442 of the vane 40 may reducea frictional force between the vane 40 and the inner circumferential surface of the multi lobemotor ring 30 while enabling the vane 40 to maintain a contact with the inner circumferentialsurface of the multi lobe motor ring 30 during rotation of the inner rotor 50. In some aspect, anumber of vanes 40 may be larger than a number of lobes 36 to prevent bypass flow of theworking medium.
[0032] FIG. 5 depicts a top view of a vane 40 having a coil spring and FIG. 6 depicts thecorresponding perspective view. Each of the first 41 and second 42 subvanes may include anoffset slot 411, 422 in the interior of the subvane where an elastic member 430 can be placed inthe offset slots 411, 422. The elastic member 430 may include a spring. In some aspects, theelastic member 430 may include a coil spring, a flat spring or the like. While the first 41 andsecond 42 subvanes may remain, in part, in contact with each other, one end 431 of the coilspring 430 may be in contact with a surface of the offset slot 411 in the first subvane 41, therebypushing the end 451 of the first subvane 41 forward. Resultantly, the end 451 of the firstsubvane 41 may form a contact with an inner surface of the first end plate 21 (see FIG. 1),thereby forming a seal between the vane 40 and the first end plate 21. Similarly, the other end432 of the coil spring 430 may be in contact with a surface of the offset slot 422 in the secondsubvane 42, thereby pushing the end 452 of the second subvane 42 to the opposite direction tothe forwarded first subvane 41. Resultantly, the end 452 of the second subvane 42 may form acontact with an inner surface of the second end plate 22 (see FIG. 1), thereby forming a sealbetween the vane 40 and the second end plate 22. This type of split vane design may allow thevanes to force a seal to the end plates 21, 22 so that the motor 100 can work at much highermedium pressures compared to a conventional vane motor.
[0033] FIG. 7 depicts a top view of a vane 40 having a flat spring and FIG. 8 depicts thecorresponding perspective view where the flat spring 460 is placed in the offset slots 411, 422.Similar to the coil spring 430 in FIGS. 5-6, while the first 41 and second 42 subvanes may remain, in part, in contact with each other, the end 451 of the first subvane 41 is pushed forward,thereby forming a seal between the first subvane 41 and the first end plate 21. The end 452 ofthe second subvane 42 forms a seal between the second subvane 42 and the second end plate 22.
[0034] FIG. 9 depicts a perspective view of the multi lobe motor ring 30, the plurality ofvanes 40 and the inner rotor 50. The multi lobe motor ring 30 may enclose the plurality of vanes40 and the inner rotor 50. The inner rotor 50 may include a plurality of vane slots 53 to housethe plurality of vanes 40. The plurality of the vane slots 53 may be circumferentially arranged atequal angular intervals in the outer surface of the inner rotor 50. Each vane 40 may bepositioned within the corresponding vane slot 53 in a direction perpendicular to a central rotationaxis ao of the inner rotor 50. During rotation of the inner rotor 50 about the central axis ao of theinner rotor 50, fluid pressure may cause the vane 40 to slide outwardly so that the rounded sides441, 442 of the vane 40 can be forced outside the vane slot 53 and form a contact with the innercircumferential surface of the multi lobe motor ring 30. In one aspect, the vane slot 53 may notrequire an expansion member to push the vane 40 outwardly to have the vane 40 in contact withthe inner circumferential surface of the multi lobe motor ring 30. Alternatively, the vane slot 53may include an expansion member to augment the outwardly-acting centrifugal force. Theexpansion member may include a spring, a compressed gas or any other suitable means toaugment the outwardly-acting centrifugal force.
[0035] The inner rotor 50 may include one or more sealing ridges 51. The sealing ridge51 may be placed between a side of the inner rotor 50 and the end plates 21, 22 (see FIG. 1).
The sealing ridge 51 may form a seal between the inner rotor 50 and the end plates 21, 22 andreduce the pressurized area against the end plates. The inner rotor 50 may further include a driveslot 52. The drive slot 52 may hold the drive 60 (see FIG. 2) passing through the inner rotor 50.In one aspect, the central rotation axis ao of the inner rotor 50 may be aligned with the passingdirection of the drive 60. In some aspects, the inner rotor 50 may not move in a directionperpendicular to the central rotation axis during rotation of the inner rotor 50.
[0036] FIG. 10 depicts an end view of the multi lobe motor ring 30, the plurality of vanes40, and the inner rotor 50. The multi lobe motor ring 30 may enclose the plurality of vanes 40and the inner rotor 50. The inner circumferential surface of the multi lobe motor ring 30 mayinclude the plurality of lobes 36. The inner circumferential surface of the multi lobe motor ring30, the outer circumferential surface of inner rotor 50 and the end plates 21, 22 (see FIG. 1) may form a plurality of working chambers 38. In one aspect, each chamber 38 may be formed by twoadjacent lobes 36, the inner circumferential surface of the multi lobe motor ring 30 and the outercircumferential surface of inner rotor 50 where the chamber is closed by two end plates 21, 22.
[0037] Each chamber 38 may have an equal volume with respect to each other. In someaspects, the rotation axis ao of the inner rotor 50 may be fixed so that each chamber 38 maymaintain the equal volume during rotation of the inner rotor 50. The working medium enteringthe inlet port 11 of the outer port ring 10 (see FIG. 1) may be received by the inlet flow groove31 (see FIG. 1) on the outer circumferential surface of the multi lobe motor ring 30. Theworking medium on the inlet flow groove 31 may enter each chamber 38 by way of the inlet 34in each lobe 36 and act on a vane 40 projecting from the inner rotor 50 to generate a torque,thereby rotating the inner rotor 50 in a clockwise or counter clockwise direction about the centralrotation axis ao of inner rotor 50. Similarly, the working medium may exit the chamber 38 byway of the outlet 35 and may be subsequently discharged by way of the outlet groove 32 and theoutlet port 12 of the outer port ring 10 (see FIG. 1). The medium flow path according to thedisclosure may allow the working medium to feed all of the inlets and outlets in the plurality oflobes 36 without requiring multiple external connections. In addition, this type of medium flowpath may allow the rotation of the rotor 50 reversible without removing and repositioning themotor 100.
[0038] FIG. 11 depicts a portion of an exemplary chamber 38. The working mediumentering the working chamber 38a by way of inlet 34a may act on the vane 40 projecting fromthe inner rotor 50, thereby rotating the inner rotor 50 as indicated by the arrow. After rotatingthe inner rotor 50, the working medium may exit the chamber 38a by way of outlet 35a. In oneaspect, a working chamber may include an inlet and an outlet. In some aspects, a workingchamber may receive a working medium by way of an inlet and discharge the working mediumby way of an outlet that may be located in the nearest neighboring lobe in the rotation directionof the inner rotor 50. In various aspects, a working chamber may receive a working medium byway of an inlet and discharge the working medium by way of an outlet that may be located in thenearest neighboring lobe in the clockwise rotation direction of the inner rotor 50.
[0039] Each chamber may produce an equal amount of torque acting on the vanes 40.
The plurality of lobes including inlets 34 and outlets 35 may generate a torque arm at each of theplurality of the vanes 40. In one aspect, the torque rotating the motor 100 may be multiplied by the number of lobes 36. In various aspects, the rotary power motor 100 may need no side loadand no secondary nut runner.
