Patent number: 11752453Abstract: A deaeration device for a fluid includes a reservoir that contains a portion of the fluid, a fluid flow path that carries a portion of the fluid, a pressure regulating structure that creates a pressure gradient along the fluid flow path, a fluid exit in the fluid flow path, and a fluid entrance in the fluid flow path. The pressure gradient causes some of the fluid to exit the fluid flow path through the fluid exit and join the fluid in the reservoir. The pressure gradient causes some of the fluid from the reservoir to join the fluid flow path through the fluid entrance.Type: GrantFiled: January 18, 2022Date of Patent: September 12, 2023Assignee: APPLE INC.Inventors: Paul D. Yeomans, Vincent G. Johnston, John M. Kearney

Patent number: 10828582Abstract: An electric vehicle drive unit includes an inverter, a gear box, an electric motor coupled to the inverter and to the gear box, a cooling jacket, and coupled to the gear box, a main coolant inlet, a coolant outlet, and an external passive air bleed device. The cooling jacket has a cooling chamber and surrounds at least a portion of the electric motor. The main coolant inlet couples to the cooling jacket. The coolant outlet is located at a lower portion of the gear box. The external passive air bleed device runs between an upper portion of the cooling jacket and the coolant outlet. The inverter may couple to a first side of the gear box and the electric motor may couple to a second side of the gear box such that the inverter and the electric motor reside on opposite sides of the gear box.Type: GrantFiled: November 22, 2017Date of Patent: November 10, 2020Assignee: Tesla, Inc.Inventors: Vincent G. Johnston, Paul Daniel Yeomans, Riccardo Marco Pagliarella
