Abstract
A material supply assembly includes a valve assembly having an outer valve member and an inner valve member rotatable relative to the outer valve member. A base assembly includes an base structure and an actuator. An engagement structure is operative between the outer valve member and the actuator to prevent relative movement between the outer valve member and the actuator. A locking structure is operative between the inner valve member and the base structure to prevent relative movement between the inner valve member and the base structure. Movement of the actuator relative to the base structure moves the outer valve member relative to the inner valve member to operate the valve assembly.
