Abstract
The invention pertains to a valve assembly particularly useful in injection mold apparatus of the type comprising a pair of abutting mold body members having registering cavity portions and channels in their abutting interface surfaces. The valve assembly comprises a generally tubular mounting member and an elongate valve element having a portion mounted within the mounting member for rotation therein and a portion extending axially outwardly from the mounting member. The extending portion of the valve element has an axially directed end face with a recess therein opening axially and radially of the valve element. Detent formations are cooperative between the mounting member and the valve element for retaining the valve element in a desired one of a plurality of positions with respect to the mounting member. A biasing spring cooperative between the mounting member and valve element urges the detent formations into engagement, but is yieldable to permit rotation of the valve element from one to another of its positions upon the application of sufficient torque to the valve element.
