Center radius of grooves offset from the axis of rotation of discs in the direction opposite the mandrel. The invention is aimed at increasing the life of the ball valve by reducing friction wear in contact with each other surfaces of disc and sides bars when turning the ball relative to the saddles. 2) TAP. Philadelphia Condos helps readers to explore varied viewpoints. Publication number 2328645. Patentee Shanaurin Anatoly L., Makarov, Vladimir VasilevichOsobennostyu design is that contains a valve placed in the housing cap, spring-loaded sealing seat, which interact with the pushers. Thrusters controlled by rod and in the form of two profiled jaws.
Profile cams cover tube and rigidly connected by bars. Hear other arguments on the topic with John Savignano. The rods pass through the coaxial connector. Hubs are located in recesses cork. The invention is aimed at improving the reliability of the crane by eliminating the complex mating surfaces of elements meaning of these inventions is reduced to that with a plug rotating cams, one of which is located above the cap, the other under – stopper. If you would like to know more then you should visit Elie Rieder. Spring-loaded saddle and made floating. The cams are attached to the cork and have a profile such that in the closed position and is open between the seats and the cams have a gap, and the seals between the seat and the surface of the plug gap is absent. In this position the seat under the influence spring loaded against the surface of the tube and valve tightness. Then, when you turn the plug, the gap between the saddles and selected cams, cams and squeeze the saddle, the spring is compressed, sealing seat away from the surface cork and it has the ability to freely rotate.
