description An improved shear/seal ram assembly used in ram-type BOPs is disclosed. The disclosed invention is a unique shear/seal ram assembly in which rail seal actuators attached to or integrally formed in a planar surface of one shear blade mate with and slide within corresponding rail guide grooves formed in a planar surface of a second shear blade. As the shear blades move over each other, the rail seal actuators slide within the rail guide grooves, eventually coming into contact with a seal actuator plate of a unique blade-to-blade seal assembly placed within a shear blade seal groove. Continued movement of the shear blades over each other causes the rail seal actuators to compress, or "energize," the blade-to-blade seal of the blade-to-blade seal assembly, thereby providing a pressure tight seal between the shear blade assemblies.
