  • Oil reservoir vent system with oil separator and method thereof
    Patent number: 5681372
    Abstract: A device and method for separating oil from the vent of an oil reservoir, such as a sump of an oil-free compressor, includes a suction pump for drawing in air from the oil reservoir through a first venting line and delivering the air through a second venting line to a filter on the one hand, and a connection between the oil reservoir and the environment on the other hand. The suction pump always draws a flow at a rate which is greater than a normal venting flow to the sump such that flow through the connection is always from the environment to the oil reservoir in order to maintain a constant air content and pressure in the oil reservoir.
