Abstract

The invention relates to a scroll (10) used for a turbine, and the scroll comprises an outer wall (12). The outer wall (12) defines round external radial limitation of the scroll (10). The scroll (10) is characterized in that the outer wall (12) has constant circumferential diameter. The scroll also comprises end walls (14,16) which can be separated axially, and the end walls (14,16) extend inward from the radial direction of the outer wall (12), to limit an air chamber between the end walls, and a periphery internal opening (20) on the radial internal boundary of the scroll (10). Any one of the first end wall (14) and the second end wall (16) or both of the first end wall (14) and the second end wall (16) can curl, so that on a circumferential direction (28), the first end wall (14) and the second end wall (16) extend from a first point of the outer wall (12) and get back to the first point of the outer wall (12), and the axial width (26) of the outer wall (12) is reduced.

Description

technical field [0001] The present disclosure relates to the arrangement of scrolls in turbomachines. Background technique [0002] It is known in the art relating to turbomachines to provide an inlet duct which changes from an open duct to an annular passage for delivering gas to the inlet of the turbine with relatively equal pressure and flow distribution around the annular inlet of the turbine. In the case of an offset system connection, the inlet pipe can be combined with an annular scroll providing a chamber-like volume to distribute the exhaust gas equally through the angled vanes of the nozzle ring to the energy conversion vanes of the turbine wheel . The equal distribution of exhaust gases to the annular turbine inlet provides the advantage of minimal plenum area where it allows a relatively short axial distance for connecting the exhaust manifold with the laterally offset turbine inlet to the turbine. [0003] exist figure 1 The arrangement of the inlet scroll fo...
