The drive system may comprise a rotatable housing (12) having a first fluid chamber (20) and a second fluid chamber (22) in mutual communication. A first pump (26) may be disposed in the housing for displacement of fluid in the first chamber and may be coupled to an input shaft (16). A second pump (28) may be disposed in the housing for displacement of fluid in the second chamber and may be coupled to an output shaft (18). A body (14) having a third fluid chamber (24) that is in communication with the second fluid chamber. A third pump (281) may disposed in the body for displacement of fluid in the third fluid chamber and drivingly coupled to the housing.",
