Abstract (en)
[origin: EP1936200A2] A lubricant-sealed rotary vane vacuum pump and motor has a pump stage located within a housing, a safety valve, a lubricant pump with an inlet and outlet, an external lubricant reservoir and hydraulic line. The lubricant delivered through the line opens the safety valve. The line from the lubricant pump to the safety valve has a branch line allowing lubricant under pressure to flow into the lubricant reservoir.
