A system comprises a first piston comprising a first piston shaft and a first drive pin. A first piston cylinder comprises a first body and a first groove, wherein the first groove defines a first aperture, the first aperture oriented axially along the first body and configured to receive the first drive pin. The first body encloses the first piston and allows the first piston to travel axially within the first piston cylinder. A drive shaft comprises an axis, a drive groove, and a surface, wherein the drive groove forms a continuous channel along the surface and receives the first drive pin. In one embodiment, a first distribution wheel comprises a first face, a second face, a first inlet aperture, and a first outlet aperture. The first distribution wheel couples to the first piston cylinder and to the drive shaft at a first end of the drive shaft, and rotates axially with the drive shaft along the axis of the drive shaft. The first inlet aperture allows hydraulic fluid to pass through the first face and the second face and the first outlet aperture defines a groove on the second face.

1. A system, comprising: a hydraulic engine comprising a sump, the hydraulic engine configured to provide rotational energy to a load shaft;wherein the hydraulic engine is further configured to receive pressurized hydraulic fluid and to collect hydraulic fluid in the sump;a reservoir coupled to the sump and configured to receive hydraulic fluid from the sump, and to store retrieved hydraulic fluid;a pump coupled to the reservoir and the hydraulic engine and configured to receive hydraulic fluid from the reservoir and to deliver hydraulic fluid to the hydraulic engine;wherein the hydraulic engine comprises: a first piston comprising a first piston shaft and a first drive pin;a first piston cylinder comprising a first body and a first groove, wherein the first groove is configured to define a first aperture, the first aperture oriented axially along the first body and configured to receive the first drive pin;wherein the first body is configured to enclose the first piston and to allow the first piston to travel axially within the first piston cylinder;a drive shaft comprising an axis, a drive groove, and a surface, wherein the drive groove forms a continuous channel along the surface and is configured to receive the first drive pin;a first distribution wheel comprising a first face, a second face, a first inlet aperture, and a first outlet aperture;wherein the first distribution wheel is configured to couple to the first piston cylinder and to the drive shaft at a first end of the drive shaft, and to rotate axially with the drive shaft along the axis of the drive shaft;wherein the first inlet aperture is configured to receive hydraulic fluid from the pump and to allow hydraulic fluid to pass through the first face and the second face;wherein the first outlet aperture defines a groove on the second face and is configured to receive hydraulic fluid from the cylinder and to deliver hydraulic fluid to the sump. 2. The system of claim 1, further comprising: a second distribution wheel coupled to the drive shaft and comprising a third face, a fourth face, a second inlet aperture, and a second outlet aperture;wherein the second distribution wheel is configured to couple to the first piston cylinder and to the drive shaft at a second end of the drive shaft, and to rotate axially with the drive shaft along the axis of the drive shaft;wherein the second inlet aperture is configured to receive hydraulic fluid from the pump and allow hydraulic fluid to pass through the third face and the fourth face; andwherein the second outlet aperture defines a groove on the fourth face and is configured to receive hydraulic fluid from the cylinder and to deliver hydraulic fluid to the sump. 3. The system of claim 2, wherein the second distribution wheel is further configured to rotate axially 180 degrees out of phase with the first distribution wheel. 4. The system of claim 1, further comprising a shell coupled to the first piston cylinder and the drive shaft and configured to enclose the first piston cylinder and the drive shaft. 5. The system of claim 1, further comprising: a second piston comprising a second piston shaft and a second drive pin;a second piston cylinder comprising a second body and a second groove, wherein the second groove is configured to define a second aperture, the second aperture oriented axially along the second body and configured to receive the second drive pin;wherein the second body is configured to enclose the second piston and to allow the second piston to travel axially within the second piston cylinder; andwherein the drive groove is further configured to receive the second drive pin.
