Abstract
A valve control unit for anti-lock and traction control systems for automotive vehicles and valve structures for the valve control unit. The valve control unit has a valve body housing having cylindrical cavities for receiving the internal portion of the valves and a counterbore forming an annular shoulder. Each valve has a radial flange received in the counterbore and seated on the annular shoulder. The periphery of the counterbore is swaged to form an inwardly directed annular lip securing the radial flange in the counterbore. The swaged annular lip also forms a fluid tight seal between the radial lip and the valve body housing. The annular lip is formed by a swaging tool orbited in a rosette pattern. The swaging of the annular lip permits closer spacing between the valves reducing the size and weight of the valve control unit.
