An assembly held down with suction cups repairs damage to an automobile windshield and the like. The rod of an extrusion assembly pushes liquefied resin through the interior of a tube and out the end thereof into the damaged area. The tube, jacketed by a vacuum container supplied by a vacuum pump, may be advanced to tightly contact a compression grommet shaped to seal off part of the vacuum created therein. Once that is done, partial withdrawal of the extrusion rod strengthens the vacuum. Certain obstructions, or stops, are situated to prevent damage to the windshield which might otherwise occur if the assembly were advanced too tightly against the windshield.

A vane pump as recited in claim 18, wherein the leak path comprises arcuate channels formed in the first end surface of the body portion of the rotor member, the arcuate channels extending between each vane slot. 22. A vane pump as recited in claim 21, wherein the arcuate channels are spaced from the central axis by a radial distance, the radial distance defining the predetermined amount of wear.
