Abstract
A rotating gate valve for access to vacuum chambers, and the like, employs a rotating gate member which is alternatively aligned to cover or to uncover a slot in a concentric valve body, the ends of which are sealed and serve as supports for a shaft. Eccentric lobes on the shaft engage corresponding cam surfaces on a gate member causing it to be urged into high force contact with the body when sealing of the chamber is desired.
