The pump features a variable discharge port design which adjusts automatically to the internal compression ratio of the vacuum pump resulting in maximum efficiency throughout the vacuum range.
我们公司生产的液环真空泵，具有不同的出料口，自动调节内部压缩率，已达到最大的真空效率。
And they themselves are more attention to eliminate internal management, improve the burden of output ratio, reduce costs and improve the overall efficiency.
而他们自身则更多地关注消除内部管理的负担、提高产出比、降低成本和提高整体效率的方面。
The proposal of increasingcompression ratio without essential increase in temp. and pressure makes it possible to raise the efficiency of internal combustion engine.
提出了在几乎不增大温度和压强的前提下，增大压缩比，使提高内燃机效率成为可能。
