ABSTRACT:
A steam flow vacuum pump has a grooved cylindrical pump body surrounded by a housing having a radius slightly greater than the pump body and a high-power ventilator pulsating the air in the housing. The housing is provided with vents on the opposite side to the ventilator. The swirling flow of the air causes a great cooling of the pump body.
