pumps were designed for use in aggregates in combination with a rotary vane pump as a variable pump. The functional principle of Roots vacuum pumps or vacuum boosters is very similar to that of rotary vane pumps. Through the entrance (<span class=\"color-primary\">A<\/span>) air flows into the rotors (<span class=\"color-primary\">C D<\/span>) formed conveyor cell in the housing. The cell is then pushed through the following piston head (<span class=\"color-primary\">f<\/span>) separated from the inlet. The air in the cell (<span class=\"color-primary\">E<\/span>) is now forwarded without reduction until it reaches the output (<span class=\"color-primary\">B<\/span>) is reached, from where the air with higher absolute pressure is pushed from the pressure area into the incoming cell in order to then be expelled. Some models are equipped with an automatic by-pass valve (<span class=\"color-primary\">G<\/span>), which limits the pressure difference between inlet and outlet.<\/span><\/p>\n<p><span
