Patent number: 11225776Abstract: A hydraulic system for recovering potential energy of a load implement of a mobile construction vehicle. The hydraulic system includes first and second actuators and control valving. The first and second actuators are configured to be coupled to the load implement for controlling raising and lowering of the load element. The control valving is operable between a first position at which, during a lowering of the load implement, the control valving directs hydraulic fluid from one of the first and second actuators to an accumulator to charge the accumulator, and a second position at which the control valving directs hydraulic fluid from the accumulator to one or more of the first and second actuators to power the one or more of the first and second actuators to raise the load element.Type: GrantFiled: January 28, 2021Date of Patent: January 18, 2022Assignee: Parker-Hannifin CorporationInventors: Nicholas N. White, James Howland, Hao Zhang, Blake Carl

Patent number: 9879403Abstract: A hydraulic machine includes an undercarriage; a rotating structure rotatably mounted on the undercarriage and configured to rotate with and with respect to the undercarriage; a first controller configured to receive user input and configured; a user interface configured to accept commands from a user and output a command signal to the controller; and a first gyroscope fixed to the rotating structure and electrically connected to the controller and configured to provide a data signal of rotation information of the rotating structure to the controller. An axis of rotation of the gyroscope is parallel to the axis of rotation of the rotating structure. The controller is configured to generate a control signal to control the rotating structure and cause the rotating structure to rotate with respect to the undercarriage based on the command signal from the user interface and the data signal from the first gyroscope.Type: GrantFiled: August 8, 2014Date of Patent: January 30, 2018Assignee: Parker-Hannifin CorporationInventors: Nicholas N.

Publication number: 20150361970Abstract: 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 par 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.Type: ApplicationFiled: February 4, 2014Publication date: December 17, 2015Applicant: Parker-Hannifin Corporation ("Parker")Inventors: Nicholas N.
