Patent number: 10337537Abstract: A system for determining a health status of a tank is provided. The system includes a temperature sensor, a pressure sensor, a sensor coupled to a hydraulic actuator, a breather valve, and a controller. The controller is configured to receive a signal indicative of a temperature and a volume of a fluid within the tank from the temperature sensor and the sensor coupled to the hydraulic actuator respectively. The controller is configured to determine an estimated pressure of the fluid within the tank based on the received signals and a breather performance curve. The controller is configured to receive a signal indicative of a pressure of the fluid within the tank and compare it with the estimated pressure. The controller is also configured to determine the health status of the tank and to actuate one or more of an operator console display unit and the hydraulic actuator.Type: GrantFiled: August 30, 2017Date of Patent: July 2, 2019Assignee: Caterpillar Inc.Inventors: Jason Brinkman, Richard Andrew Carpenter

Patent number: 9739273Abstract: An overspeed protection method for a machine having an engine drivably coupled to a pump is disclosed. The method includes determining a speed of a rotatable component connected to the engine based on an engine speed and determining a minimum power limit based on the speed of the rotatable component. The minimum power limit corresponds to a minimum power required to retard the engine in order to prevent an overspeed condition of the rotatable component. The method further includes determining a minimum flow limit based on a predetermined relationship between the minimum power limit and the minimum flow limit. The minimum flow limit corresponds to a required flow of the pump in order to provide the minimum power limit. The method further includes regulating the pump in order to achieve the minimum flow limit.Type: GrantFiled: May 21, 2014Date of Patent: August 22, 2017Assignee: Caterpillar Inc.Inventors: Matthew S. Marquette, Jeffrey K. Berry, Jason Brinkman

Patent number: 8997471Abstract: A hydraulic system for a machine is disclosed. The hydraulic system may include a fluid tank, a first manifold, a valve body, a second manifold, and a plurality of conduits. The first manifold may be operatively attached to the fluid tank and have at least two inlets and at least one outlet in fluid communication with the fluid tank. The number of the at least one outlet may be less than the number of the at least two inlets. The second manifold may be operatively attached to the valve body and have at least one inlet in fluid communication with the valve body and at least two outlets. The number of the at least one inlet may be less than the number of the at least two outlets. The plurality of conduits may fluidly connect the at least two inlets of the first manifold and the at least two outlets of the second manifold.Type: GrantFiled: November 30, 2012Date of Patent: April 7, 2015Assignee: Caterpillar Inc.Inventors: Jason Brinkman, Shaun Currier, Eric Jakubiak

Publication number: 20060095163Abstract: Consistent with an aspect of the disclosure, a method for controlling a hydraulic cylinder is provided. The hydraulic cylinder is provided with a chamber and configured to receive fluid from a valve. The method includes receiving a user input and determining a desired velocity of the hydraulic cylinder in accordance with the user input. In addition, the velocity of the hydraulic cylinder is measured and a position of the valve is determined in accordance with the desired velocity of the hydraulic cylinder and the measured velocity of the hydraulic cylinder. The method further includes determining a desired force to be applied to the valve in accordance with a difference between the desired and measured velocities of the hydraulic cylinder, and actuating the valve in accordance with the desired force to thereby inject the fluid into the chamber and move the hydraulic cylinder.Type: ApplicationFiled: October 29, 2004Publication date: May 4, 2006Inventors: Jerry Wear, Hongliu Du, Greg Ferkol, Mark Vonderwell, Jeff Kuehn, Jason Brinkman

Publication number: 20050066655Abstract: A cylinder assembly is disclosed. The cylinder assembly may include a cylinder body having an internal cavity therein and a piston and rod assembly disposed for axial movement within the internal cavity of the cylinder body. The piston and rod assembly may have an axial passage extending therein. The cylinder assembly may further include a tubular element received within the axial passage of the piston and rod assembly. At least a portion of the tubular element may extend out of the axial passage and into the internal cavity of the cylinder body between the axial passage and a wall of the cylinder body.Type: ApplicationFiled: September 26, 2003Publication date: March 31, 2005Inventors: Robert Aarestad, Jason Brinkman, Paul Hagen, John Krone, George Romack
