This is achieved in that the valve body comprises a foot part and a plate, the foot part being guided displaceably in the valve housing in the axis of symmetry, the plate having, in a staggered manner, a first groove and a second groove for holding a first sealing ring and a second sealing ring, the two sealing rings bearing against the sealing surface when the valve is closed and being flowed around in series when the valve is open.

Abstract: A shroud assembly for a turbine portion of a gas turbine engine, the shroud assembly comprising an annular ceramic shroud ring, a plurality of arcuate shroud support segments, and a plurality of inwardly biased resilient members. The annular ceramic shroud ring is circumferentially disposed about radially extending blades of a turbine rotor and partially defines an annular hot gas passage of the turbine portion.

Abstract: Disclosed are flat panel field emitter displays whose unit cell structure adopt a planar cathode structure in stead of a conventional microtip structure, so as to increase the degree of integration and can be operated at low operation voltages at high speeds. In the structure, a channel insulator is formed below the cathode and underlaid by a gate. By means of the gate voltage, the electron emission from the cathode can be controlled. The electrodes in the structure are arranged in the order of anode, cathode and gate, allowing the simplification of processes. With the ease of controlling the distance between electrodes, the displays can be applied for almost all video systems from small sizes to large screen area displays, in place of conventional displays. The displays allows conventional semiconductor processes and facilities to be utilized as they are.
