Abstract: A lubrication system vent valve includes a valve body having a flow passage with an inlet fluidly coupled with a supply and an outlet fluidly coupled with a dispenser, and a vent passage with an inlet port fluidly coupled with the flow passage and an outlet port. A closure element disposed within the vent passage has a threaded portion and is linearly displaceable between an open position where the vent ports are fluidly coupled to permit lubricant flow from the primary passage and out of the body through the vent outlet port, and a closed position at which fluid flow between the vent ports is substantially prevented. A motor has a shaft with a threaded portion engaged with the closure element such that shaft rotation in one direction displaces the closure element toward the closed position and shaft rotation in an opposing direction displaces the element toward the open position.
