Abstract

Przedmiotem zgłoszenia jest wysokosprawnościowa pompa zębata z kompensacją luzu. Pompa ma korpus, w którym wykonane są otwory ssące połączone poprzez komorę roboczą, w której pracują koła zębate (3) z otworami tłocznymi. Korpus wykonany jest z części zewnętrznej (1) i części wewnętrznej w postaci tulei (2), gdzie w części zewnętrznej (1), po obu stronach otworu tłocznego (6) wykonane są zatoki (10) i (11), oddzielone od komory roboczej (14) tuleją (2) i uszczelnieniami.The subject of the application is a high-performance gear pump with backlash compensation. The pump has a body in which suction holes are made, connected through a working chamber in which gear wheels (3) work with pressure holes. The body is made of an external part (1) and an internal part in the form of a sleeve (2), where in the external part (1), on both sides of the pressure hole (6), bays (10) and (11) are made, separated from the working chamber (14) by a sleeve (2) and seals.
