Latest Patents
One of Greene's latest patents is the "Hydraulic axial piston unit and method for controlling of a hydraulic axial piston unit." This invention features a hydraulic axial piston unit that includes a rotational group for driving or being driven by a driving shaft. It also incorporates a tiltable displacement element for adjusting the displacement volume of the rotational group. The design includes a rotatable cylinder block with working pistons that move reciprocally within cylinder bores, facilitating the conveyance of hydraulic fluid from an inlet port to an outlet port on a valve segment. The valve segment is equipped with at least two control ports that can be sequentially connected to the cylinder bores during the rotation of the cylinder block. Additionally, a hydraulic fluid injector is connected to one control port, allowing for the sequential injection of pressurized hydraulic fluid into the passing cylinder bores, while the other control port enables the drainage of hydraulic fluid from the cylinder bores.
Another notable patent is the "POG holder and method." This device features a disk-like, circular base with a front face and a rear face. The front face has a rim that extends partially along the perimeter, designed to grasp the POG and hold it snugly against the front face. A gripping member on the rear face allows the base to attach to at least one spoke of a bicycle wheel.
