  • Patent number: 10539242
    Abstract: The disclosed embodiments include systems and methods for retaining a seat insert of a ball valve in place within a seat ring of the ball valve. In particular, the seat insert is an annular ring having a tapered section on an outer wall of the annular ring. The tapered section of the seat insert is configured to mate with a shoulder in an outer surface of a profiled groove of the seat ring. The seat insert snaps into the profiled groove with the shoulder, thereby preventing axial movement of the seat insert with respect to the profiled groove of the seat ring. In addition, a locking ring also fits within the profiled groove of the seat ring to prevent axial and radial movement of the seat insert with respect to the profiled groove of the seat ring. More specifically, once the seat insert has been snapped into place within the profiled groove of the seat ring, the locking ring is also inserted into the profiled groove of the seat ring.

  • Patent number: 10443441
    Abstract: A valve device of a jet engine includes a body, a seat and a flow path between an inlet and an outlet that can be closed and opened. Depending on an actuating force that results from a fluid pressure at a front surface of the body facing the inlet, as well as from a closing force applied to the body, the body can be transferred between open and closed states, and can be transferred into an operational state in which the flow path is opened by a setting device depending on an ambient pressure. The flow path can be opened via the setting device such that a flow cross-section of the flow path corresponds to at least 80% of the flow cross-section of the flow path in the area of the inlet across the entire extension of the flow path between the inlet and the outlet.

  • Patent number: 9068661
    Abstract: A recess is provided at the periphery of the flapper so that a corner that defines this recess engages an o-ring seal in a seat for the flapper. A reduced contact area of the flapper on the o-ring seal results in increased pressure over the actual contact area. The pressure applied over the contact area also forces a distortion in the o-ring that has a part of the o-ring not restrained due to the presence of the recess moving out of the surrounding o-ring groove so that the corner on the flapper pinches the o-ring that now is partly in and partly extending from its surrounding groove. Sealing is obtained at lower differential pressures and the o-ring is better fixated as a result of the pinch effect of the corner on the flapper.

  • Patent number: 8882947
    Abstract: In a method of manufacturing tires for vehicle wheels, a green tire, once formed, is transferred into a vulcanization mold and pressed against the holding walls of a molding cavity. Concurrently with the pressing step, a fluid present between the green tire and the holding walls is evacuated through vent valves. The tire is brought into contact with the closing head of each valve so as to push it toward a closed position at which the closing head forms a contact seat spaced apart from the inner surface of the molding cavity in order to define an embedding recess between the inner surface of the molding cavity and the closing head.
