High torque rotary motor with multi-lobed ring with inlet and outlet

A method for manufacturing a rotary motor, comprising:

• placing a plurality of vanes in an outer circumferential surface of an inner rotary member;
• configuring a plurality of lobes each of which comprises an inlet and an outlet;
• circumferentially arranging the lobes in an inner circumferential surface of a multi lobe member;
• forming a plurality of chambers wherein each chamber is placed between two adjacent lobes and is surrounded, at least in part, by the inner circumferential surface of the multi lobe member and the outer circumferential surface of the inner rotary member;
• surrounding, at least in part, the multi lobe member with an outer port member comprising an inlet port and an outlet port;
• forming an inlet groove and an outlet groove on an outer surface of the multi lobe member;
• aligning the inlet with the inlet groove and further aligning the inlet groove with the inlet port;
• and
• aligning the outlet with the outlet groove and further aligning the outlet groove with the outlet port.

An apparatus for use in a hydraulic torque system, comprising:

• rotating means for housing a plurality of torque generating means;
• multi lobe means for supplying a working fluid to act on the torque generating means wherein the multi lobe means comprises two or more contacting portions, wherein each of the contacting portions comprises an inlet and an outlet for the working fluid, and wherein at least one of the contacting portions is in contact with at least one of an inner circumferential surface of the rotating means;
• a plurality of chamber means for holding the working fluid wherein each of the plurality of the chamber means is surrounded, at least in part, by an inner surface of the multi lobe means and an outer surface of the rotating means, wherein at least one of the plurality of the chamber means is placed between two contacting portions, and wherein each of the plurality of chamber means is configured to maintain a substantially equal volume during rotation of the rotating means;
• outer port means for surrounding, at least in part, the multi lobe means;
• and
• means for covering and sealing the means for supplying the working fluid and the rotating means,
• wherein the outer port means comprises an inlet port and an outlet port,
• wherein the multi lobe means comprises an inlet groove and an outlet groove on an outer circumferential surface of the multi lobe means.
