Variable radial fluid device with differential piston control

摘要

According to one embodiment, a radial fluid device (300) comprises a cylinder block (320), a first plurality of pistons (340a-340f) including a first piston, and a second plurality of pistons (340a'-340f') including a second piston. Each of the first plurality of pistons (340a-340f) are slidably received within a different one of a first plurality of radially extending cylinders. Each of the second plurality of pistons (340a'-340f') are slidably received within a different one of a second plurality of radially extending cylinders. The second piston is configurable to begin its stroke at a different time relative to the first piston within the first cylinder pair.
