A windshield repair injector, to repair star, bulls-eye and elongated cracks in a laminated windshield. The device has a stepped threaded section for easy removal and installation. When the injector is placed against a glass surface, upward motion of a piston provides a vacuum in the piston chamber for removing moisture trapped in the damage region. Afterwards insertion of an optically clear resin, with an optical coefficient equal to glass is inserted under pressure, creating a permanent and virtually invisible repair.

[ What is claimed is:] [1.] A windshield repair injector comprising:a cylindrical injector body extending from a first end to a second end said cylindrical injector body having therethrough a cylindrical bore which extends from said first end to said second end of said cylindrical injector body, said bore having an interior wall dimensioned and finished for accepting therein a rotatably or vertically movable cylindrical piston, said piston having a first end and a second end said first end containing thereon an actuator threaded section and an outer knob, said knob positioned above, and affixed to said actuator threaded section, said knob installed for allowing an operator to rotate said piston when said piston is located within said bore and a fixed pin is installed between the threads of said actuator threaded section, said piston further having grooves thereon for installation of a plurality of O-rings, said O-rings sized to produce a seal between said bore wall and said piston body, wherein said actuator threaded section on said piston, when rotated, communicate with said fixed pin, forcing said piston to travel in a direction towards the first end of said cylindrical body when said piston is rotated counter-clockwise, and to travel in a direction towards the second end of said cylindrical body when said piston is rotated clockwise, said cylindrical body second end further having a counterbore for accepting a gasket or an O-ring therein, for creating a seal between said injector body and said windshield, said cylindrical body further having an other threaded section thereon for mounting said cylindrical injector body on a platform designed for mounting said injector, said platform having a means for securing said platform and said injector to said windshield to be repaired;wherein the vertical motion of said piston occurs when said piston body is rotated clockwise or counter-clockwise;wherein said pin is removed and replaced by a lever operated gear and mounting housing for producing motion of said piston when a lever attached to said gear is rotated.
