Abstract: A power system for storing, recovering, and/or using energy from a vehicle powered by a prime mover, including a hydraulic pump/motor configured to be driven by the prime mover, a hydraulic accumulator for storing energy, a body hydraulic and/or an auxiliary hydraulic, and a valve manifold selectively fluidly connecting the hydraulic pump/motor to the hydraulic accumulator and the body hydraulic and/or the auxiliary hydraulic. When the prime mover is operating, the hydraulic pump/motor may selectively power the body hydraulic and/or auxiliary hydraulic, or may selectively charge the hydraulic accumulator, or both. When the prime mover is off, the hydraulic accumulator may selectively power the hydraulic pump/motor to start the prime mover. The stored energy in the hydraulic accumulator may be used to power other hydraulic components of the vehicle as well. Such a configuration provides a less complex and more fuel efficient hydraulic power system for starting the prime mover.

Abstract: A compressor is provided suitable for compressing natural gas from a pressure associated with a residential gas supply to a pressure suitable for an automotive gas tank. The compressor utilizes a pair of pneumatic cylinders driven by a hydraulic cylinder to compress the gas in a multi-stage process. Various embodiments are provided with respect to the gas compressor portion and the drive portion. A pressure boost system is also provided which utilizes an internal control valve and internal orifice through the piston of one of the pneumatic cylinders.
