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.
