    Abstract: A protection mechanism for a lubricant reservoir is mounted within a valve protection chamber disposed on an actuator. The protection mechanism includes a valve actuating plate and an elastic member biasing the valve actuating plate upwards. The actuator is pushed upwards by a rising level of lubricant as the lubricant reservoir is filled. When the reservoir is full, the actuator causes the valve actuating plate to contact a valve stem. The valve actuating plate pushes the valve stem up to shut off a flow of lubricant to the reservoir through the shut off valve. During an overfill event the actuator shifts upward due to the rising level of the lubricant in the reservoir. As the actuator shifts upward, the elastic member compresses such that valve actuating plate remains static relative to the lubricant reservoir as actuator rises.

    Abstract: A dual parallel outlet check valve includes a first one-way valve and a second one-way valve. The first one-way valve and the second one-way valve are normally closed valves. Both the first one-way valve and the second one-way valve are disposed in a valve housing, and the first one-way valve is disposed adjacent to and runs parallel with the second one-way valve. The first one-way valve allows lubricant to flow downstream from a fluid chamber to build a downstream pressure, thereby causing lubricant applicators to dispense lubricant. The second one-way valve allows lubricant to flow upstream back into the fluid chamber, thereby allowing the downstream pressure to drop and the lubricant applicators to reset.

    Abstract: A centerfill assembly for a lubricant reservoir includes a hollow tube for receiving lubricant from the top of the reservoir and loading the lubricant into the reservoir near the bottom of the reservoir. Loading the lubricant near the bottom of the reservoir introduces lubricant near where the stirring paddles mix the lubricant and near where the lubricant is loaded to the lubricant pump. Adding the lubricant near where the pumps load and near the stirring paddles helps to eliminate air pockets in the lubricant. In addition, having the centerfill rod minimizes exterior plumbing and allows for the mounting of valves on the fill line

    Abstract: A lubrication system comprises a lubricant reservoir, a inlet into the lubricant reservoir, a diaphragm plate, an actuator pin, a refill inlet, a refill outlet, and a shutoff valve. The diaphragm plate is disposed at a topmost location within the lubricant reservoir. The actuator pin is coupled to the diaphragm plate such that filling the lubricant reservoir drives the actuator pin from a first position to a second position. The refill inlet is configured to receive lubricant, and the refill outlet is fluidly connected to the inlet of the lubricant reservoir. The shutoff valve is 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.
