Patent number: 11506297Abstract: A valve body defines a work passage, a high-pressure channel fluidly connected to the work passage, a tank passage, and a cavity disposed between the high-pressure channel and the tank passage. The cavity fluidly connects the high-pressure channel and the tank passage. The cavity is defined at least in part by a first portion within which a relief valve threadedly engages, a second portion disposed adjacent to the high-pressure channel, and an annulus interposed between the first portion and the second portion. The annulus fluidly connects to the tank passage. A surface area of the relief valve exposed to the annulus is greater than a cross-sectional area of the high-pressure channel.Type: GrantFiled: December 9, 2020Date of Patent: November 22, 2022Assignee: Caterpillar Inc.Inventors: Mikhail A. Sorokin, Salik Abdul Syed, Wesley Thomas Payne

Patent number: 8997476Abstract: A machine includes a hydraulic cylinder configured to raise and lower a boom of the machine, and an accumulator selectively fluidly connected to the hydraulic cylinder. The accumulator is configured to receive fluid from the hydraulic cylinder during lowering of the boom. The machine also includes a hydraulic motor fluidly connected to the accumulator via an independent metering valve. The machine further includes a fan driven by the hydraulic motor and configured to assist in cooling fluid displaced from the hydraulic cylinder.Type: GrantFiled: July 27, 2012Date of Patent: April 7, 2015Assignee: Caterpillar Inc.Inventors: Jason Lee Brinkman, Wesley Thomas Payne, Aristoteles Rosa Neto

Patent number: 8763388Abstract: A hydraulic system for a machine is disclosed. The hydraulic system has a source of pressurized fluid, a fluid actuator, and a tank. The hydraulic system utilizes a directional control valve to direct flow between the source, the actuator, and the tank. The hydraulic further utilizes a variable backpressure control valve to control the system backpressure.Type: GrantFiled: September 2, 2010Date of Patent: July 1, 2014Assignee: Caterpillar Inc.Inventor: Wesley Thomas Payne

Publication number: 20140026546Abstract: A regeneration valve for a hydraulic circuit may include a valve element for controlling flow between first, second, and third ports. The valve element may be formed with a flow slot that generates a slot flow force when hydraulic fluid flows therethrough. The flow slot may be configured so that a predetermined fluid low rate may generate a slot flow force sufficient to actuate the valve element from a first position to a second position. In the second position, the valve element may divert a portion of flow from the second port to the first port is diverted to the third port. The flow slot may be configured so that the fluid exits the slot at an exit angle that varies as the valve element moves between first and second positions, thereby to provide a more uniform flow force across the range of travel of the valve element.Type: ApplicationFiled: July 25, 2012Publication date: January 30, 2014Applicant: CATERPILLAR, INC.Inventors: Kevin A. Bacon, Gang Victor Wen, Wesley Thomas Payne

Patent number: 8387378Abstract: A hydraulic system for a mobile machine having an implement is disclosed. The hydraulic system may have a hydraulic actuator configured to move the implement, a storage device configured to store pressurized fluid, and a valve operable to fluidly communicate the storage device with the hydraulic actuator. The hydraulic system may also have a sensor associated with the mobile machine to generate a signal indicative of a speed of the mobile machine, and a controller in communication with the valve and the sensor. The controller may be configured to compare the speed of the mobile machine to a setpoint and to determine an amount of time elapsed while the speed of the mobile machine exceeds the setpoint. The controller may further be configured to selectively operate the valve to fluidly communicate the storage device with the actuator based on the elapsed amount of time and the speed to cushion movement of the implement.Type: GrantFiled: July 29, 2008Date of Patent: March 5, 2013Assignee: Caterpillar Inc.Inventors: Wesley Thomas Payne, Eric Alexander Rost

Patent number: 7293494Abstract: A hydraulic valve stack for a work machine is disclosed. The hydraulic valve stack has a base with a first mounting surface and a second mounting surface. The base is connectable to the work machine and has at least one fluid passageway extending through the base from the first mounting surface to the second mounting surface. The hydraulic valve stack also has a permanent valve assembly configured to control a permanent function of the work machine and an optional valve assembly configured to control an optional function of the work machine. The permanent valve assembly is connectable to the first mounting surface of the base, while the optional valve assembly is connectable to the second mounting surface of the base. Each of the permanent and the optional valve assemblies have at least one fluid passageway in communication with the at least one fluid passageway of the base.Type: GrantFiled: December 23, 2004Date of Patent: November 13, 2007Assignee: Caterpillar Inc.Inventors: Christopher Michael Morency, Edward Lee Stapleton, Wesley Thomas Payne
