Single-Vane Vacuum Pumps for Vacuum Generation

Mechanical single-vane vacuum pump Pneumatically acting brake boosters are installed in passenger cars and light-duty trucks to increase braking reliability and ease of handling. For diesel engines and increasingly also for gasoline engines, specifically those with direct injection, vacuum pumps are used for supplying brake boosters and servo valves with vacuum, for controlling exhaust gas re- circulation systems and turbo chargers, for example. Based on longstanding experience with pistons, membrane and swinging-vane vacuum pumps a single-vane vacuum pump was developed in line with...

be fitted with a secondary vacuum port for servo devices. Moreover, the single-vane vacuum pump is also available in combination with an oil pump as a so-called tandem pump. mum flexibility is ensured for accommodating the system on the engine. All presently known vacuum conditions specified by the various customers can be met with the single-vane vacuum pump model range available. The rotor with integrated shaft is arranged overhung in the customer-specific pump flange. The single-vane vacuum pump needs lube oil for sealing the internal gaps, for heat dissipation and for lubricating the...

efficient buildup of the lubricating film, contributing to extremely low wearing rates and reduced power consumption. Thanks to the selective use of steel components the N2 series is applicable even at extreme temperatures which may prevail, for example, in the direct surrounds of the exhaust system. make for extremely low power consumption. In addition, an extraordinarily smooth run thanks to minimized rotational imbalances at the driving shaft contributes to the high quality standard of this series. The choice of a deep-drawn steel body ensures excellent cost efficiency. EVO series N3...

Paying tribute to increased rev demands, e.g. for tandem pumps, high-speed resistant applications are developed. The low power consumption achieved with the diverse installation sizes and technologies contributes to fuel savings. All series can be driven via the camshaft or a secondary shaft. The connecting element is a coupling designed to compensate for offsets due to the assembly or to tolerances. Oil is supplied from the engine’s oil circuit. Single-vane vacuum pumps are delivered ready for installation, with customer-specific intake connections and integrated check valve as well as a...
