Single Vane Vacuum Pump

The pump has a very simple and robust set-up and never the less has a very high capacity. The pressure and suction valve and the oil duct are cut open. If the rotor is turned, the enlargement and reduction of the working area can be seen particularly well, as can the contact of the slide shoes in each position of the vane. In order tosupply a vacuum for brake boosters, vacuum pumps are used in both diesel and,increasingly, in Otto engines.
