Abstract
Głowica pompy rotacyjnej zawiera cylinder i poruszający się obrotowo wewnątrz cylindra rotor. W cylindrze umieszczone są równomiernie otwory, w których znajdują się ruchome tłoczki i popychacze napędzane obrotem pierścienia krzywkowego połączonego z wałkiem napędowym. Otwory łączą się z kanałem obwodowym (26) w cylindrze głowicy (5), natomiast rotor (8) wyposażony jest w pierścieniowy kanał i drugi pierścieniowy kanał (25) oraz łączące oba pierścieniowe kanały co najmniej dwa kanały wzdłużne (7) zasadniczo równoległe do osi podłużnej rotora (8) i kanał skośny (6) usytuowany pod kątem, korzystnie 7 - 21 stopni, względem kanału (7). Cylinder głowicy (5) posiada pary kanałów doprowadzających (3 i 4), których otwory znajdują się na odcinku cylindra głowicy (5) stykającym się z rotorem (8) w miejscu gdzie umieszczone są kanały (7) i kanał skośny (6). Głowica pompy posiada kanał spustowy (15) połączony z pierścieniowym kanałem i kanałami wylotowymi. Rotor (8) jest ruchomy wzdłużnie względem cylindra głowicy (5).The rotary pump head comprises a cylinder and a rotor rotating within the cylinder. The cylinder has evenly placed holes in which there are movable pistons and pushers driven by the rotation of a cam ring connected to the drive shaft. The holes connect to the peripheral channel (26) in the cylinder head (5), while the rotor (8) is equipped with an annular channel and a second annular channel (25) and at least two longitudinal channels (7) connecting the annular channels essentially parallel to the axis longitudinal rotor (8) and an oblique channel (6) located at an angle, preferably 7 - 21 degrees, relative to the channel (7). The cylinder head (5) has pairs of supply channels (3 and 4), whose holes are located on the cylinder cylinder section (5) in contact with the rotor (8) in the place where the channels (7) and the oblique channel (6) are located. The pump head has a drainage channel (15) connected to the annular channel and outlet channels. The rotor (8) is movable longitudinally relative to the cylinder head (5).
