Rotatable valve assembly includes a mounting mechanism for rotatably mounting a valve in a housing. The mounting mechanism includes a shaft having an outside end extending through the housing. A conversion mechanism converts fluid pressure in the housing into torque exerted on the shaft. A release mechanism is located outside the housing for preventing rotation of the shaft and valve when the torque exerted on the shaft is below a selected magnitude. A linearizing mechanism converts the forces exerted on the release mechanism by the shaft into a linear force. The release mechanism allows the shaft to rotate when the torque exerted on the shaft and the linear force exerted on the release mechanism exceeds a selected magnitude. A seal is provided for sealing the gap between the valve and the housing in the closed position of the valve. The seal includes a support edge sealingly secured to the housing, a sealing edge extending inwardly from the support edge into contact with the valve circumference in the closed position of the valve, and a seal body connected between the support edge and the sealing edge and spacing the sealing edge axially towards the inlet face of the valve from the support edge.

[ What is claimed is:] [1.] Rotatable valve assembly, comprising:a housing having an inlet and an outlet defining a fluid passageway through the housing;a valve, located in the passageway, and having an inlet face, an outlet face, and a circumference extending around the valve between the inlet and outlet faces; the valve being rotatable between a closed position in which the inlet face faces into the housing inlet, the outlet face faces into the housing outlet, and the valve circumference faces the surrounding fluid passageway and defines a gap between the valve circumference and the fluid passageway, and an open position; the valve circumference defining a valve plane;mounting means for rotatably mounting the valve about a rotational axis in the housing;a seal for sealing the gap between the valve circumference and the fluid passageway in the closed position of the valve, the seal including a support edge sealingly secured to the fluid passageway, a sealing edge extending inwardly from the support edge into contact with the valve circumference in the closed position of the valve, and a seal body connected between the support edge and the sealing edge and displacing the sealing edge axially towards the inlet face of the valve from the support edge, the seal defining a seal plane extending across the fluid passageway; andwherein the rotational axis of the valve lies in the seal plane and in the valve plane.
