Patent number: 11788633Abstract: A spool for a spool valve assembly defines a spool longitudinal axis and includes a first land module defining a first land module circumferential surface, a second land module defining a second land module circumferential surface, and a first metering module. The first metering module has a first end cap and a second end cap. The first end cap is coupled to the first land module, and the second end cap is coupled to the second land module, to form the spool. The first metering module may further include at least two pillars extending from the first end cap to the second end cap, wherein the at least two pillars are entirely disposed within a virtual first metering module hollow cylinder area that surrounds a virtual first metering module central core area concentric with the spool longitudinal axis.Type: GrantFiled: August 6, 2021Date of Patent: October 17, 2023Assignee: Caterpillar Inc.Inventors: Kevin L.

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.

Patent number: 9829014Abstract: An independent metering valve circuit includes an actuator, a set of independent metering valves, an independent metering valve pre-compensator, an inverse resolver, and a signal conditioning element. The set of independent metering valves are fluidly coupled to the actuator and configured to independently control a flow of a hydraulic fluid to the actuator. The independent metering valve pre-compensator is configured to control the flow of the hydraulic fluid to the set of independent metering valves. The inverse resolver is configured to receive a first pressure signal from the independent metering valve circuit and a second pressure signal from a load-sense hydraulic system and output a third pressure signal. The signal conditioning element is configured to receive the third pressure signal and output a forth pressure signal configured to control a pump fluidly coupled to the load-sense hydraulic system and the independent metering valve circuit.Type: GrantFiled: April 27, 2015Date of Patent: November 28, 2017Assignee: Caterpillar Inc.Inventors: Andrew J. Kleitsch, Pengfei Ma, Jason L. Brinkman, Mikhail Sorokin

Publication number: 20090014624Abstract: The present invention relates to a portable illumination device (100) for illuminating an object (200) through a medium having an absorption coefficient, the illumination device (100) comprising a lighting unit (101) including at least two differently colored light sources (Li-L3) for emitting light having a color distribution, and a control unit (105) for adjusting the color distribution. The control unit (105) is adapted to receive a distance estimate corresponding to the distance between the illumination device (100) and the object (200), and adjust the color distribution depending on the distance estimate, such that light reflected from the object is perceived to have substantially correct color reproduction. An advantage with the invention is that an object (200) illuminated through a medium will be perceived by a user using the portable illumination device (100) as having a substantially correct color reproduction.Type: ApplicationFiled: February 15, 2007Publication date: January 15, 2009Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Martin Hillebrand Blees, Ferry Barrios, Wilhelmus Frederik Hoeben, Mikhail Sorokin, Ludo Haenen, Bennie Simpelaar, Nebojsa Fisekovic
