Abstract

Siłownik pneumatyczny, posiadający cylinder z dwiema końcowymi pokrywami, z których pokrywa przednia posiada otwór osiowy dla przemieszczającego się pomiędzy nimi tłoczyska z tłokiem, charakteryzuje się tym, że cylinder (1) wyposażony jest w otwór (9) do którego przyłączona jest wytwornica zmiennego ciśnienia hydraulicznego (10), w cylinder (1) wsunięty jest cylinder wewnętrzny (2), w którym umieszczone jest tłoczysko (6) z tłokiem (7), cylinder wewnętrzny (2) w przekroju poprzecznym ma kształt pierścienia, przy czym obrys zewnętrzny pierścienia ma kształt elipsy, a obrys wewnętrzny pierścienia ma kształt okręgu, przy czym oś wielka elipsy jest krótsza od średnicy wewnętrznej cylindra (1), cylinder wewnętrzny (2) zakończony jest z obu stron kołnierzami o średnicy zasadniczo równej średnicy wewnętrznej cylindra (1), a przestrzeń pomiędzy cylindrem (1) i cylindrem wewnętrznym (2) wypełniona jest cieczą hydrauliczną (12), tłoczysko (6) posiada elementy dystansowe (13, 14), o długości równej co najmniej dwukrotnej grubości kołnierza cylindra wewnętrznego (2).The pneumatic cylinder, having a cylinder with two end covers, from which the front cover has an axial hole for the piston rod moving between them, is characterized by the fact that the cylinder (1) is equipped with a hole (9) to which the variable hydraulic pressure generator is connected (10), the inner cylinder (2) is inserted into the cylinder (1), in which the piston rod (6) with the piston (7) is located, the inner cylinder (2) in the cross section has the shape of a ring, the outer contour of the ring having the shape of the ellipse, and the inner contour of the ring is in the shape of a circle, the major axis of the ellipse is shorter than the inner diameter of the cylinder (1), the inner cylinder (2) ends on both sides with flanges with a diameter substantially equal to the inner diameter of the cylinder (1), and the space between the cylinder (1) and the inner cylinder (2) are filled with hydraulic fluid (12), the piston rod (6) after sits spacers (13, 14), with a length equal to at least twice the thickness of the inner cylinder flange (2).
