Publication number: 20240077074Abstract: A device including a reservoir configured to receive a lubricant from a machine lubricated with the lubricant. The device also includes a pressure equalizer connected to the reservoir. The device also includes a first loop comprising a first line system through which the lubricant flows between the machine and the reservoir. The lubricant within the first loop is at a first pressure. The device also includes a temperature regulation system configured to regulate a temperature of the lubricant. The device also includes a second loop comprising a second line system through which the lubricant flows between the temperature regulation system and the reservoir. The lubricant within the second loop is at a second pressure that is less than the first pressure. The second loop is separate from the first loop.Type: ApplicationFiled: September 1, 2022Publication date: March 7, 2024Applicant: EKU POWER DRIVES INC.Inventors: Levi Wayne BECK, Benedikt Peter ZIER, Andreas PFISTER

Publication number: 20240077073Abstract: A device including a reservoir configured to contain a lubricant. One or more sets of baffles are disposed in the reservoir. The one or more sets of baffles separate the reservoir into a hot zone and a cold zone. The one or more sets of baffles permit at least some flow of the lubricant between the hot zone and the cold zone. The device also includes a machine loop drain placed in the reservoir to drain lubricant returning from a machine into the hot zone. The device also includes a thermal management loop drain placed in the reservoir to drain lubricant returning from a thermal management system into the cold zone. The device also includes a thermal management loop inlet placed in the reservoir to draw lubricant from the hot zone. The device also includes a machine loop inlet placed in the reservoir to draw lubricant from the cold zone.Type: ApplicationFiled: September 1, 2022Publication date: March 7, 2024Applicant: EKU POWER DRIVES INC.Inventor: Benedikt Peter ZIER
