    Abstract: A fluid power system includes a hydraulic machine. A pilot-controlled supply valve controls high-pressure fluid to the machine. The valve is coupled between the hydraulic machine and a high-pressure fluid source, and includes a control port for an actuation signal. The supply valve allows passage of fluid from the machine to the fluid source, but blocks passage of fluid from the fluid source to the machine while closed, or permits passage of fluid from the fluid source to the machine while open. The supply valve biases toward closed or open according to an actuation signal at the control port. A pressurization valve is also coupled between the hydraulic machine and the high-pressure fluid source. The pressurization valve blocks passage of fluid from the fluid source to the machine while in a first position, and allows a restricted passage of fluid between its input and output ports while in a second position, to allow pressure to equalize on either side of the supply valve before the supply valve opens.

    Abstract: A hydraulic pressure accumulator has an interior chamber containing a fire-suppressing gas such as nitrogen. The fire-suppressing gas in the accumulator is fluidly connected to a thermal device, such as a valve with a thermal fuse or a controlled valve triggered by a thermal sensor. The thermal device is designed to open a fluid connection between the accumulator's interior chamber to ambient when the exterior temperature exceeds a determined safety threshold, thereby releasing the fire suppressing gas from the accumulator.

    Abstract: A vehicle includes an integrated drive module coupled to an axle thereof. The module includes a hydraulic motor configured to provide motive power at an output shaft, and a differential for distributing the motive power to right and left portions of the axle. The hydraulic motor and the differential are encased within a common housing. The vehicle may include a second integrated drive module having, within a housing, a second hydraulic motor (or multiple hydraulic motors), and a second differential coupled thereto and configured to distribute motive power to right and left portions of a second axle. The second module may also include a transmission within the same housing. The transmission may be a two speed or other multi-speed transmission. The second module is configured to operate in neutral while power demand is below a threshold, and to engage while the power demand exceeds the threshold. The second module may be configured to remain engaged for full-time four-wheel-drive operation.

    Abstract: A method for operating a series hybrid vehicle in a manner that responds to an operator's demand for power output, while maximizing engine efficiency and minimizing disruptions in vehicle drivability, may include determining, when the operator makes a demand for power output, whether the secondary power source(s) is supplied with secondary energy stored in an energy storage device(s), direct input energy generated by an engine(s), or both, based on an amount of available secondary energy stored in a secondary storage device(s) alone, or in combination with vehicle speed. While the engine is generating secondary energy, the power efficiency level at which the engine operates may depend on the amount of available stored secondary energy alone, or in combination with vehicle speed. Further, when the engine is not generating secondary energy, the engine may be selectively turned off or idled in response to various operating conditions.

    Abstract: A variable displacement hydraulic/pump motor has a yoke with a pair of shafts aligned to define a yoke pivot axis and connected to a valve plate therebetween having intake and discharge apertures. A rotatable cylinder barrel has piston cylinders open at one end to receive a piston head and opening through fluid ports at another end, flush against the valve plate surface. A drive block is mounted on an input/output shaft for rotation about a central axis of rotation inclined at an angle relative to the longitudinal axis of the cylinder barrel which may be changed by a drive engaging the yoke at a point near its pivot axis. Loads on bushings supporting the yoke shafts are reduced by providing radially extending fluid ports in the shafts and in communication with the intake and discharge apertures of the valve plate.
