Abstract

A pendulum gate valve with a pressure tight housing and inlet and outlet openings arranged on opposite sides of the housing. The drive rod for the pendulum frame is guided throughout its total path by a joint connected to the pendulum frame which can swivel about the shaft of the pendulum frame but can in addition also move independently of the swiveling motion of the pendulum frame. A guide mechanism is provided for the further movement of the joint outside the swiveling range, which forces the joint onto a path that runs substantially parallel to the drive rod. The guide mechanism consists of a thrust rod forming part of the pressing device which urges the gate valve plate against the sealing bearing surface and which is connected to the drive rod. The thrust rod is mounted in a longitudinally movable manner in the pendulum frame and runs parallel to the drive rod in the closed position of the gate valve plate.
