Lubricant distribution system with overfill protection

A shut-off valve for lubricant, the shut-off valve comprising:

• a valve housing having an inlet, an outlet, and passaging fluidly connecting the inlet and the outlet;
• a blocker carried by the valve housing, the blocker being selectively positionable relative to the valve housing for permitting flow of lubricant through the passaging from the inlet to the outlet and for preventing flow of lubricant through the passaging from the inlet to the outlet, the blocker being selectively positionable in a closed position for preventing flow of lubricant through the passaging;
• and
• a valve actuator carried by the valve housing, the valve actuator being operatively connected to the blocker for selectively positioning the blocker relative to the valve housing, the valve actuator having an actuation surface configured to be moved to move the blocker into the closed position in which the blocker prevents flow of lubricant through the passaging, the valve actuator configured to permit the actuation surface to be movable relative to the blocker when the blocker is in the closed position.

A lubricant distribution system comprising:

• a reservoir configured to contain lubricant, the reservoir including a follower configured to move up and down in the reservoir in response to a changing level of lubricant in the reservoir;
• an inlet arranged to deliver lubricant to the reservoir;
• and
• a shut-off valve in fluid communication with the inlet, the shut-off valve including a blocker selectively positionable for permitting flow of lubricant through the inlet and for preventing flow of lubricant through the inlet, the shut-off valve including a valve actuator having a follower engagement surface arranged to be engaged by the follower when lubricant in the reservoir fills to a predetermined level to position the blocker to prevent flow of lubricant through the inlet, the follower engagement surface being movable relative to the blocker, the blocker being configured to move along a blocker axis for selectively permitting and preventing flow of lubricant through the inlet, the follower engagement surface being movable relative to the blocker along the blocker axis.
