Finite elastic tube for return run of hydraulic servo steering in vehicles from matrix made of elastomeric material, has tube formed as bent tube, which has cross section varying from circular cross section on part of its entire length

摘要

The finite elastic tube has rigid supports embedded in the matrix, which is firmly clamped at its connecting ends (2,5) on connecting fittings. The tube is formed as bent tube (1), which has a cross section varying from a circular cross section on a part of its entire length up to a pressure that is clearly under the working pressure, where the sum of the part length with cross section that varies from a circular form is smaller than the total length of the bent tube. The bent tube has an approximately circular cross section in the rest of the part length.
