Patent number: 11946397Abstract: An engine system optionally including: a crankcase of an engine having a blow-by gas passing therethrough; a liquid source containing a liquid; and an oil separating apparatus in fluid communication with the blow-by gas. The oil separating apparatus having a coalescing filter to separate oil from the blow-by gas. Separate from the blow-by gas and the coalescing filter, the oil separating apparatus is in fluid communication with the liquid source to receive the liquid. The liquid is passed through the oil separating apparatus in a heat exchange relationship with the blow-by gas to maintain a desired temperature range for the blow-by gas.Type: GrantFiled: May 1, 2023Date of Patent: April 2, 2024Assignee: Caterpillar Inc.Inventors: Rodney Allen Lawrence, Brandyn A. Stack, Joshua Amiel Lehe, Nicholas Edwin Wainscott, Eric John Forthofer

Patent number: 11867099Abstract: Apparatuses, systems and methods are disclosed for separating oil from a blow-by gas of an engine. An example includes engine system includes a crankcase having a blow-by gas passing therethrough, a compressor configured to receive air and compress the air, an aftercooler, an oil separating apparatus and a jet pump. The aftercooler communicates with the compressor and is configured to cool at least a portion of the air compressed by the compressor. The oil separating apparatus communicates with the blow-by gas. The oil separating apparatus communicates with a boost air that is a mixture of the compressed air from the compressor and cooled air from the aftercooler. The jet pump communicates with both the blow-by gas after leaving the oil separating apparatus and the boost air after leaving the oil separating apparatus and is configured to combine the blow-by gas and the boost air.Type: GrantFiled: January 3, 2023Date of Patent: January 9, 2024Assignee: Caterpillar Inc.Inventors: Rodney Allen Lawrence, Brandyn A. Stack, Joshua Amiel Lehe

Patent number: 11118630Abstract: A valve system may include a valve having a housing with a bore and a valve member positioned within the bore. The valve member may include a valve shaft with a recess. The valve system may also include an actuator having an actuator shaft with an end portion. An adapter may couple the valve shaft and the actuator shaft. The adapter may include a body having a shape corresponding to a shape of the recess of the valve shaft for fitting the adapter within the recess and an aperture extending into the body. The aperture may have a shape corresponding to a shape of the end portion of the actuator shaft for press fitting the adapter onto the actuator shaft. The adapter may fit within the recess and press fit coupled to the actuator shaft.Type: GrantFiled: February 8, 2019Date of Patent: September 14, 2021Assignee: Caterpillar Inc.Inventors: Rodney A.
