摘要： An improved wellhead stuffing box device is disclosed, having a coil spring, between a loading plate and the packing members of a stuffing box, and a housing threaded over the loading plate and the coil spring onto the outer wall of the stuffing box. The loading plate is adjacent the coil spring, which applies constant pressure on the packing members, causing the packing members to bulge continuously, as they wear out, thereby maintaining a seal between the packing members and a polish rod while in operation through the life of the packing members. The loading plate may be adjusted to adjust the spring force in the coil spring. The entire assembly has an aperture through its central longitudinal axis for the polish rod to oscillate there through. Embodiments include a stuffing box with an improved stuffing box cap.
