Claim:
1. Apparatus for cooling rotating or sliding shaft packing material comprising: an end flange having: a cylindrical bore having a flange first inner diameter and defining an axis connecting a flange first surface and a flange second surface of said flange, a circular counterbore having a flange second inner diameter and centered on the axis extending a first selected distance beyond the flange first surface info said flange, forming thereby a flange first interior flat surface perpendicular to the axis, and at least two first initially radial coolant ports opening to a lateral surface of said flange between the first surface and the second surface at one end and opening perpendicular to the first interior flange surface at a second end, at least one packing cup having a packing cup first flat side and a packing cup second flat side parallel thereto, a cylindrical bore therethrough having a packing cup first inner diameter equal to the flange first inner diameter and centered on the axis, a circular counterbore having a packing cup second inner diameter smaller than the flange second inner diameter and centered on the axis extending a first selected distance beyond the packing cup first flat side into said at least one packing cup, forming thereby a packing cup interior flat surface perpendicular to the axis, a first groove extending annularly in the packing cup first flat side having a first diameter larger smaller than the flange second inner diameter, at least one axial cooling port opening into the first groove, a second groove extending annularly in the packing cup first flat side having a second diameter larger smaller than the flange second inner diameter and not intersecting the first groove, at least two axial coolant ports, at least one of which opens into the first groove at one end and connects to the packing cup second flat side at the other end, and at least one of the at least two coolant ports opens into the second groove at one end and connects to the packing cup second flat side at the other end, at least one of the at least two cooling ports of said end flange being in fluid communication with the first groove, and at least one of the at least two cooling ports being in fluid communication with the second groove; a coolant return cup having a return cup first flat side and a return cup second flat side parallel thereto, a cylindrical bore therethrough having a return cup first inner diameter equal to the flange first inner diameter and centered on the axis, a circular counterbore having a return cup second inner diameter equal to the flange second inner diameter packing cup second inner diameter and centered on the axis extending a selected distance beyond the return cup first flat side, forming thereby a return cup interior flat surface perpendicular to the axis, a circular groove in the return cup first flat side having a diameter smaller than the flange second inner diameter, the at least two coolant ports exiting the return cup second flat side of said at least one packing cup being in fluid communication with the circular groove; the flange first interior flat surface is in contact with the packing cup first flat side and the packing cup second flat side is in contact with the return cup first flat side; a shaft having an outside diameter such that said shaft rotatably moves or slidably moves within the bores of said flange, said at least one packing cup, and said coolant return cup; packing material disposed within the circular counterbore of said flange, the circular counterbore of said at least one packing cup and the circular counterbore of said coolant return cup and adapted to form a seal between the first Interior flat surface of said flange and the second side of said at least one packing cup, and between the flat interior surface of said at least one packing cup and the second side of said coolant return cup, respectively, and with said shaft; and a coolant pump for moving coolant fluid through the cooling ports of said flange, said at least one packing cup, and said coolant return cup.
