  • Patent number: 10774989
    Abstract: A lubricant injector includes a body having an inlet at a first end fluidly coupleable to a lubricant source, an outlet, a delivery chamber coupled with the outlet and a bore defined by a substantially circular inner surface with a constant inner diameter and spaced axially from the body inlet, the bore having a first port fluidly connected with the body inlet and a second port disposed between the body inlet and the first port and fluidly connected with the delivery chamber. A generally circular cylindrical piston is disposed within the bore so as to divide the bore into an operating chamber fluidly coupled with the first port and a measuring chamber fluidly coupled with the second port and located axially between the operating chamber and the body first end. The piston has an outer circumferential slidably disposed against the bore inner surface and having a generally constant outside diameter.

  • Patent number: 10767813
    Abstract: A lubricant injector includes a body having an inlet fluidly coupleable to a lubricant source, an outlet, and an elongated bore extending along an axis and having an outer end proximal to the body second end, a closed inner end spaced axially from the body first end, a first port, and a second port disposed generally between the bore closed end and the first port. A delivery chamber separate from the bore has an inlet port and an outlet port fluidly coupled with the body outlet. A piston disposed within the bore divides the bore into an operating chamber coupled with the first port and a measuring chamber coupled with the second port. The operating chamber is fluidly coupled with the inlet and the measuring chamber is located between the bore closed end and the operating chamber and is fluidly coupleable with the inlet and alternatively with the delivery chamber.

  • Publication number: 20190195423
    Abstract: A lubricant injector includes a body having an inlet fluidly coupleable to a lubricant source, an outlet, and an elongated bore extending along an axis and having an outer end proximal to the body second end, a closed inner end spaced axially from the body first end, a first port, and a second port disposed generally between the bore closed end and the first port. A delivery chamber separate from the bore has an inlet port and an outlet port fluidly coupled with the body outlet.

The operating chamber is fluidly coupled with the inlet and the measuring chamber is located between the bore closed end and the operating chamber and is fluidly coupleable with the inlet and alternatively with the delivery chamber.

  • Patent number: 8887499
    Abstract: A method for overpressure control in a hydraulic system having multiple hydraulic pumps, with each hydraulic pump being connected by a respective hydraulic circuit for actuating a single respective hydraulic actuator, includes actuating a first variable displacement hydraulic pump, the first hydraulic pump being fluidly linked by a first hydraulic circuit to a first hydraulic actuator for powering the first hydraulic actuator. Upon detecting a pressure that exceeds a predetermined threshold pressure, the flow rate of the first hydraulic pump is electronically modified to a second flow rate lower than the first flow rate whereby the pressure in the first hydraulic circuit is reduced to a pressure that is below the predetermined threshold pressure.

  • Publication number: 20120324875
    Abstract: A method and system for operating a machine having first and second movable elements, first and second hydromechanical movers for moving the first and second movable elements, respectively, and first and second hydraulic pumps linked to the first and second hydromechanical movers, respectively. Movement requests for moving the first and second movable elements are processed such that the movement command to the second hydromechanical mover is reduced by a variable amount based on the magnitude of the first movement request. For commanded first hydromechanical mover movements below a certain level, flow to the second hydromechanical mover may optionally not be reduced.

  • Publication number: 20070114092
    Abstract: A hydraulic system is disclosed. The hydraulic system includes a source of pressurized fluid and a plurality of fluid actuators configured to affect an amount of resistive torque applied to an associated traction device. The hydraulic system also includes a plurality of valves each configured to selectively communicate pressurized fluid to one of the plurality of fluid actuators. The hydraulic system further includes a controller configured to control the plurality of valves as a function of at least a steering command.
