Abstract

Wynalazek dotyczy pompy zębatej o zazębieniu zewnętrznym, która ma korpus, w którym wykonany jest otwór ssący, połączony poprzez komorę roboczą, w której pracują dwa koła zębate, z otworem tłocznym, przy czym koła zębate ułożyskowane są w tulejach ślizgowych osadzonych w korpusie łożyska charakteryzuje się tym, że każda z tulei łożyskowych (2) posiada spiralny rowek (5), który łączy kanał doprowadzający z kanałem odprowadzającym czynnik roboczy i zarówno kanał doprowadzający jak i odprowadzający znajdują się w przestrzeni ssącej, a spiralny rowek (5) ma końce przeciwnych stronach bloku łożyskowego.The invention relates to a gear pump with an external toothing, which has a body in which a suction hole is made, connected through a working chamber in which two gears work, with a pressure hole, the gear wheels being mounted in slide sleeves embedded in the bearing housing. in that each of the bearing bushes (2) has a spiral groove (5) that connects the supply channel with the working medium discharge channel and both the supply and discharge channel are in the suction space, and the spiral groove (5) has ends of opposite sides of the block bearing.
