摘要:
A bearing arrangement for the pot of a centrifugal yarn spinning unit has a housing in whose cavity a radial bearing and an axial thrust bearing for the shaft of the pot are arranged. The radial bearing is fixedly mounted on a carrier which plugs an opening of the housing. The carrier is sealed to the housing by O-rings, and the shaft journaled in the bearings is received in a passage of the carrier provided with a packing in fixed spatial relationship with the radial bearing. Wear of the packing is minimized by the permanent guidance provided to the shaft by the radial bearing although the shaft may oscillate radially with the carrier during its high-speed rotation.

This invention relates to an improvement in a rotary piston engine of trochoidal design, of the epitrochoidal or hypotrochoidal type with an outer envelope, with the piston surface and/or housing bore being equidistant to the mathematically exact trochoid, and including a follow-up drive, the improvement comprising that the minus-equidistant of the piston and/or of the housing bore has a value exceeding 10% of that of the generating radius and smaller that that for which the piston contour is tangent with the follow-up drive in the dead center positions.

This invention relates to a packing strip arrangement for sealing the working chambers of rotary piston engines of trochoidal construction having a trochoidal piston rotor, a housing boundary shaped according to the coordinated outer envelope curve, and contracted portions with radial packing strips at said contracted portions, which comprises SEALING RING MEANS IN EACH OF THE LATERAL HOUSING WALLS WITHIN THE INNER ENVELOPE CURVE DESCRIBED BY THE EDGE OF THE PISTON ROTOR, SAID SEALING RING MEANS BEING CLOSED WITHIN THEMSELVES, SEALING ELEMENT MEANS STARTING FROM SAID SEALING RING MEANS, EXTENDING RADIALLY IN THE DIRECTION TO THE CONTRACTED POINTS, AND DIRECTLY ADJOINING THE RADIAL PACKING STRIPS AT THE OUTER ENDS THEREOF, AND CURVED TRANSITION ELEMENT MEANS WHICH REST AGAINST SAID SEALING RING MEANS AND GUIDE SAID SEALING ELEMENT MEANS IN THE RADIAL DIRECTION.
摘要:
This invention relates to an improvement in a rotary piston engine, of trochoidal construction, wherein for pairing reasons the formation of the housing and the piston rotor is based not only upon the trochoid but also upon the inner or outer envelope curve branches being coordinated thereto, and wherein the gas check between two adjacent working spaces or chambers is effected by means of radial packing strips; the improvement comprising that the housing and piston rotor delimitations consist of a pair of parallel curves on the same side, facing away from the radial packing strip, of the gemoetrically exact curve and extending equidistantly with respect thereto.

The hull is shaped as a transverse drive producing body with a small aspect ratio while depth steering equipment is mounted on the stern. The vessel has a water displacement which creates a static residual lift force should the power to the vessel be shut off for any reason. This allows the vessel to surface automatically. The depth steering equipment is controlled over a coaxial tow cable.

The product of the two interdependent physical magnitudes is regulated by comparing measured instantaneous values of each magnitude in alternating manner with a stored part value of a previously measured peak value of the same magnitude and of switching over the magnitude from a decreasing to an increasing value while reversing the other magnitude from an increasing to a decreasing value upon the instantaneous value algebraically equaling the stored value.
