Claim Text:
1. A lubrication system comprising: a lubricant reservoir; an inlet into the lubricant reservoir; a diaphragm plate disposed at a topmost location within the lubricant reservoir; an actuator pin coupled to the diaphragm plate such that filling the lubricant reservoir forces the diaphragm plate upward, driving the actuator pin from a first position corresponding to an unfilled reservoir state to a second position corresponding to a filled reservoir state; and a refill inlet configured to receive lubricant; a refill outlet fluidly connected to the inlet of the lubricant reservoir; and a shutoff valve connected between the refill inlet and the refill outlet, and actuated by the actuator pin so as to fluidly connect the refill inlet and refill outlet when the actuator pin is in the first position, and fluidly isolate the refill inlet from the refill outlet when the actuator pin is in the second position.
