High pressure variable vane pump with vane pins

A vane pump comprising:

• a housing comprising an internal chamber;
• an inlet port;
• an outlet port;
• a rotor rotatably mounted in the internal chamber for rotation about a rotor axis, the rotor having a plurality of vane mounting openings and a plurality of vanes mounted in and extending radially from the vane mounting openings, the vanes being slidable radially in the vane mounting openings;
• a control slide mounted in said internal chamber, the control slide having an internal surface defining a rotor receiving space, wherein the rotor receiving space is in communication with the inlet and outlet ports and the rotor is received in the rotor receiving space with the vanes slidably engaging the internal surface of the control slide such that rotating the rotor generates a pressure differential between the inlet and outlet ports to draw fluid in through the inlet port and output the fluid out through the outlet port;
• wherein the plurality of vane mounting openings are arranged in pairs of vane mounting openings that are diametrically opposed to one another with respect to the rotor axis and wherein the plurality of vanes include pairs of vanes that are diametrically opposed to one another with respect to the rotor axis,
• wherein the vanes in each said pair have an intermediate transfer member extending therebetween that shifts with one vane of each said pair retracting radially inwardly by engagement with the internal surface of the rotor receiving space for extension of the opposing vane of each said pair radially outwardly toward the internal surface of the rotor receiving space.
