Floating chuck with irrigating flow

摘要

A floating chuck incorporating a fluid path for irrigation fluid is disclosed. Fluid passages in the body and bush are connected by a rigid tube floatingly mounted by O-rings at each end. The O-rings are in fluid-sealing relationship with opposed, enlarged end sections of the fluid passages. The tube is shorter than the distance between the inner ends of the enlarged sections. Axial displacement and angular displacement of the bush relative to the body are accomplished without compromise to the fluid supply. The arrangement provides smoothness of movement between the bush and body and has low maintenance costs.
