Beschreibung
Zusammenfassung:	A hydraulic system is provided to create periodic pressure equilibrium by control groove while gear wheels being rotated, thereby obtaining a preferred volumetric efficiency. A hydraulic system comprises two gear wheels(16,18) engaging with each other. Each gear wheel having slant outer teeth are interposed between an inlet side and an outlet side. At least one control recesses(46) are formed at the ends of the gear wheels. The control recess creates a pressure equilibrium periodically. The control recess is completely covered by one tooth(20) of the slant outer teeth. At least two mutual contact points are always presented while the gear wheel is rotated. The pressure equilibrium initially leads to intermediary space formed between the two contact points.
