Abstract
According to one embodiment, a radial fluid device comprises a cylinder block, a first plurality of pistons, a second plurality of pistons, a first cam, a second cam, and a cam rotation device. Each of the first plurality of pistons are slidably received within a different one of a first plurality of radially extending cylinders. Each of the second plurality of pistons are slidably received within a different one of a second plurality of radially extending cylinders. The first cam is disposed about the first plurality of radially extending cylinders. The second cam is disposed about the second plurality of radially extending cylinders. The cam rotation device is coupled to the first cam and the second cam. The cam rotation device is operable to rotate the first cam in a first direction and the second cam in a second direction.
