Abstract: The invention relates to a turbine shaft for a steam turbine, oriented in an axial direction and comprising a first and a second flow region. According to the invention, a first material is provided in the first flow region of the turbine shaft, and a second flow region is provided in the second flow region thereof, the first material having heat-resistant properties and the second material having cold-resistant properties. The inventive turbine shaft is produced by means of a construction weld seam without any previous buffer layer welding on one of the two materials.

Abstract: A hydraulic-damping two-chamber engine mount includes a working chamber facing toward an engine, a compensating chamber, and an intermediate plate separating the chambers from each other and having an overflow conduit extending helically therein through which the chambers communicate hydraulically with one another. The intermediate plate has two sides and an outer periphery merging into a cylindrical ring extending beyond both of the sides. The ring has an outer surface with two axially superposed conduits formed therein having ends and extending over at least a portion of the outer periphery of the intermediate plate. The intermediate plate has a longitudinal axis and has a conduit portion formed therein extending obliquely relative to the longitudinal axis through which one end of each of the superposed conduits communicate with each other. An outer conduit wall in the form of a cylindrical mount housing has an inner wall surface covering the superposed conduits.

Abstract: A decoupling device for engine mounts having upper and lower liquid chambers containing hydraulic fluid for damping vibrations, includes a diaphragm liquid-tightly fastened to an upper region of the upper liquid chamber defining a diaphragm chamber divided-off from the upper liquid chamber, the diaphragm including a circular rubber body and a vibration-cancelling mass in the form of a central, circular, metallic disc adhering to the circular rubber body, the circular rubber body having upper and lower surfaces, each of the surfaces having two concentric, conical, circular slots formed therein being inclined toward each other as seen in direction from the horizontal central plane of the circular rubber body toward the surfaces thereof, and the slots being extended to the vicinity of the horizontal central plane of the circular rubber body.
