  • Patent number: 11624452
    Abstract: The disclosure is directed to an apparatus and system for adjusting rate of spool centering in a pilot-controlled hydraulic spool valve. The apparatus includes a first pilot port and a second pilot port. The apparatus includes a first valve port and a second valve port. The apparatus also includes a first hydraulic circuit connecting the first pilot port and the first valve port, wherein the first hydraulic circuit, based on a hydraulic fluid pressure of the second pilot port, comprises one of a controlled-flow condition and an unrestricted-flow condition. The apparatus further includes a second hydraulic circuit connecting the second pilot port and the second valve port, wherein the second hydraulic circuit, based on a hydraulic fluid pressure of the first pilot port, comprises one of a controlled-flow condition and an unrestricted-flow condition.

  • Patent number: 10159201
    Abstract: The present embodiments are directed to apparatus and methods for cutting an object. In one embodiment, the apparatus comprises a cutting device and an actuation device operatively coupled to the cutting device. A guide structure may be coupled at least partially between the cutting device and the actuation device. A supporting framework may provide a guiding path for linear advancement or retraction of the guide structure, and in turn linear advancement or retraction the cutting device, upon actuation of the actuation device.

  • Patent number: 8862341
    Abstract: A system is provided in which a control module may include a user interface configurable to receive input and display hydraulic control settings, wherein the hydraulic control settings include at least a hydraulic pressure setting and a hydraulic flow setting. The control module may also include a processor executable to convert the hydraulic control settings to corresponding electrical currents, wherein the electrical currents correspond to at least the hydraulic pressure setting and the hydraulic flow setting. The control module may also include one or more communication interfaces coupled to the processor configurable to output the electrical currents to the hydraulic circuit to control hydraulics that operate one or more attachments of a machine.
