FIELD: training.SUBSTANCE: each body of a line of housings is divided into sealed for incompressible fluid sections by movable partitions moving in grooves in opposite walls of the housing. Each movable partition wall has one groove of a smaller size for a band which is flexible in the cross direction. Body is made in the form of polygonal toroidal ring formed by outer and inner walls of sections. Grooves of the sections are located on the vertices of the inner and outer polygons. Band, which is closed with overlap, has spring properties which tend to reduce the circumference of the shape formed by the band. All walls of the housings, including the bottom are transparent, and in the mated bottoms and covers cases there are valve openings.EFFECT: proposed is the physics manual.1 cl, 2 dwg |
