ABSTRACT:
A rotary disk valve has a valve body provided with an annular valve seat section defining a central opening to be removably closed by a valve disk. The valve disk is supported by a drive assembly which includes a drive shaft mounted on the valve body and supporting a drive link for rotation with the shaft. The link mounts a valve disk support shaft which extends slidably through a slot in a bracket secured to the valve disk. The bracket mounts a guide cam follower pin arranged to engage a guide cam secured to the valve body. The arrangement of drive shaft, valve disk support shaft, bracket slot and guide cam and follower is such that rotation of the drive shaft through 180.degree. in one direction first moves the valve disk from open position disposed in a plane substantially perpendicular to the plane of the central opening in the valve body to an intermediate position spaced from but parallel to the valve seat surface, and then moves the valve disk linearly into sealing engagement with the valve seat section of the valve body. Reverse rotation of the drive shaft moves the valve disk from open to closed position.
