Abstract

Pompa zębata o zazębieniu zewnętrznym z kompensacją luzu obwodowego, przeznaczona do generowania energii strumienia cieczy w układach hydraulicznych i układach smarowania, utworzona z korpusu, w którym jest komora robocza (7), w której umiejscowione są zazębione ze sobą koka zębate (3, 4), oraz w którym utworzone są odchodzące od komory roboczej (7) kanał ssawny (6) i kanał tłoczny (8), charakteryzuje się tym, że korpus, w którym utworzona jest komora robocza (7), stanowi korpus wewnętrzny (2), który osadzony jest w wyposażonym w otwór tłoczny (10) korpusie zewnętrznym (1), przy czym pomiędzy korpusem wewnętrznym (2), a korpusem zewnętrznym (1) utworzona jest szczelnie oddzielona od części ssawnej komora (9), a korpus wewnętrzny (2) na obszarze otaczającym komorę roboczą (7) jest podatny na odkształcenia w kierunku do kół zębatych (3, 4) pod naporem panującego w komorze (9) ciśnienia tłoczenia.External gear pump with peripheral clearance compensation, designed to generate the energy of a liquid stream in hydraulic and lubrication systems, made of a body with a working chamber (7) in which interlocking gear wheels (3, 4) are located. , and in which the suction channel (6) and the discharge channel (8) extending from the working chamber (7) are formed, characterized in that the body in which the working chamber (7) is formed is an internal body (2), which is mounted in the outer body (1) equipped with a discharge hole (10), and between the inner body (2) and the outer body (1) there is a chamber (9) tightly separated from the suction part, and the inner body (2) on the area surrounding the working chamber (7) is susceptible to deformation towards the gears (3, 4) under the pressure of the pressing pressure prevailing in the chamber (9).
