    摘要： A preferably totally oil-free spiral compressor (1) with a high suction volume flows and a high compression ratio, is useful in particular to generate compressed air for rail vehicles. The compressor includes two spirals arranged on one side only, and includes measures to exactly guide both spirals relative to each other. For that purpose, a compression crown (15) is connected to and axially spaced from a first one of the spirals (7), and the second spiral (9) is positively guidedly driven within the compression crown (15) by a positive guidance arrangement. The positive guidance arrangement includes support rollers (17) that extend axially from the second spiral toward the compression crown and that are engaged and constrained to roll in bores (19) let into the compression crown (15) and shaped as guiding rings. By these measures, both spirals carry out orbital movements with respect to each other, as a result of the offset of their axes and under the positive guidance provided by the support rollers that roll in the bores. Also, to counteract axial forces exerted by the spirals, pressure chambers (35) are provided between the compression crown and the second spiral, to exert a counter force that urges the first and second spirals axially together.

    摘要： In a totally oil-free spiral compressor (1) with high suction volume flows and compression ratio, useful in particular to generate compressed air for rail vehicles, the spirals are arranged on one side only and measures are taken to compensate for the high axial forces that act on the spiral bearings. Compression chambers (35) arranged with an axial gap between the spirals (7, 9) of the spiral compressor (1) are fed by compression pockets (45) and support the nested spirals against each other. The compression chambers (35) are preferably arranged between a compression crown (15) joined to the driving spiral (7) and a ring wheel (37) of the forcibly driven second spiral (9), so that axial counterforces compensate for the axial forces that act upon the bearings (29, 33) of both spirals.

    摘要： A mast for a rig for a surfboard is characterized among others by the following features: a mast with a profiled cross-section in the longitudinal direction, said cross-section being formed transversely to the mast longitudinal direction and deviating from a circular shape; the profiled cross-section has the shape of a droplet or has a droplet-like design in the manner of a droplet profile; the mast has a fork tree head securing section which can be rotated or pivoted about the fork tree head securing section; the fork tree head securing section is provided with a cross-section which deviates from the droplet profile; and the mast lower part and the mast upper part of the mast consist of plastic or comprise plastic optionally with the addition of a reinforcement consisting of metal, glass fibers, and/or carbon fibers.
