    Abstract: The invention relates to a chamber, in particular a pump chamber, comprising a plate-shaped first half (10) and a plate-shaped second half (12). The first and second halves are connected to one another by a closed connecting seam (20) in a surface-to-surface relation, and at least one half has at least one aperture (14) lying within the connecting seam. Furthermore, at least the second half is thermally deformed within the closed connecting seam in such a manner that it is formed to bulge relative to the connecting surface with the first half such that a hollow space (30) is formed between the first and second halves. In a second aspect, the invention relates to a pump having a configuration as described above. In a third aspect, the invention relates to a method for producing a chamber as described above.

    Abstract: An object is to provide a highly efficient compressor while improving a refrigerant leakage, enhancing a performance of a compressor, improving durability, and enhancing reliability. The compressor comprises: a compression element comprising a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid via the discharge port; a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber; and a shaft seal which is disposed on an end portion of the bearing (main bearing) on a side opposite to the compression member and which abuts on the rotary shaft.

    Abstract: A rotary lobe pump includes two geared-together, counter-rotating shafts, to which are affixed rotors with interdigital lobes. Adjustment of the angular relationship of the rotors uses a clamping device within each rotor. The clamping device consists of a tapered, slotted bushing that is forced between a mating taper on the rotor and a locking device on the shaft by means of a flanged fastener mated to each pump shaft's threads.
