  • Publication number: 20260036215
    Abstract: A valve assembly configured to perform a fluid service on a machine is disclosed herein. The valve assembly can include an inlet/outlet port fluidically coupling a fluid component to an internal cavity defined by the valve assembly, a filter port fluidically coupling the internal cavity to a filter of the machine, and a pressure regulating system. The pressure regulating system can include a plunger head configured to transition between an open position and a closed position, a plunger head seat, and a spring comprising a spring constant configured to bias the plunger head in the open position, wherein the spring constant is configured to be overcome in response to a predetermined pressure within the machine.

  • Publication number: 20250313142
    Abstract: A vehicle body. The vehicle body comprises a fluid transfer system integrated within the vehicle body. The fluid transfer system comprises a fluid evacuation system comprising a first fluid storage container, a fluid refill system comprising a second fluid storage container, a sensing system coupled to the fluid evacuation system and the fluid refill system, and a control circuit coupled to the sensing system, the fluid evacuation system and the fluid refill system. The control circuit is configured to (1) determine an amount of a first fluid in the first fluid storage container based on a first signal from the sensing system, and (2) determine an amount of a second fluid in the second fluid storage container based on a second signal from the sensing system.
