Abstract: Spur gear pump and helical gear pump for the change law of trapping volume is analyzed. The quantitative conclusion that the change curve of trapping volume is quadratic parabola. The unloader channel which gear pump eliminate trapping from is designed.

Key words: Clearance between gears, Gear pump, Trapping, Unloader channel
