  • Patent number: 12631292
    Abstract: A valve includes a housing and a plunger. The housing defines a chamber, a set of ports, and a set of conduits. The plunger is disposed within the chamber and is configured to be moved to an actuated state in which the set of ports are fluidly coupled to each other through a first section of the chamber to define a first passageway and the set of conduits are fluidly coupled to each other through a second section of the chamber to define a second passageway. In the actuated state, the valve facilitates an inflow of a lubricant into a system through the first passageway to cause a concomitant purge and release of a used lubricant from the system through the second passageway.
