<p>The double cam sliding vane pump has four different delivery volumes derived from two groups of pump cells between adjacent vanes, and two groups of pump cells in rotor slots under the vanes. The pump has parts connected optionally with a first pump chamber, formed by rotor slots. Two inlet openings can be optionally connected to further pump chambers formed by spaces between the vanes. Two inner outlet openings can be optionally connected to external outlets which can be optionally connected to the second pump chambers. The cam ring encloses a rotor and has elliptic paths of different shapes.</p> |
