Abstract
Abstract Rotary valve device including stationary valve body means having stationary valve face means and rotary valve means having rotary valve face means sealingly engaging said stationary valve face means. Housing means surrounds said rotary valve means and defines therewith external fluid chamber means. Said rotary valve means has internal fluid chamber means and has a plurality of selectable operating positions with respect to said stationary valve body means. Actuating means is provided for actuating said rotary valve means from one selectable position to another. Said rotary valve means in one of said selectable positions blanking flow of fluid between said stationary valve face means and said rotary valve face means. Said stationary valve body means has at least one fluid port means therein. Said stationary valve face means and said rotary valve face means have registerable fluid passage means for selectably connecting said external and internal fluid chamber means in communication with said fluid port means.
