Abstract
A mounting assembly for a movable annular wall member of an inlet passageway of a variable geometry turbine. The inlet passageway is defined between the movable wall and a facing wall. The wall member is formed from a sheet material and is supported on a plurality of pins which extend parallel to the direction of movement of the wall member. The wall member comprises a tubular portion extending away from the facing wall and each pin supports a radial extending projection having a pair of spaced tabs. Each tab is engaged in a respective slot in the tubular portion of the wall member, the tabs being a relatively close fit in the direction of movement of the wall member and a relatively loose fit in a plane at right angles to the direction of movement.
Claims5
A mounting assembly for a movable annular wall member of an inlet passageway of a variable geometry turbine, wherein the inlet passageway is defined between the movable wall member and a facing wall, the movable wall member being formed from a sheet material, and the movable wall member being supported on a plurality of guide elements which are movable parallel to its direction of movement, the improvement comprising means for interconnecting said movable wall member and said guide elements with a relatively close fit in the direction of movement of said movable wall member and a relatively loose fit in a plane at right angles to the direction of movement of said movable wall member.
A mounting assembly for a movable annular wall member of an inlet passageway of a variable geometry turbine, wherein the inlet passageway is defined between the movable wall member and a facing wall, the movable wall member being formed from sheet material and further comprising a tubular portion extending away from said facing wall, and the movable wall member being supported on a plurality of guide elements comprising pins which are movable parallel to its direction of movement, the improvement comprising means for interconnecting said movable wall member and said guide elements with a relatively close fit in the direction of movement of said movable wall member and a relatively loose fit in a plane at right angles to the direction of movement of said movable wall member, said interconnecting means comprising:
- a pair of spaced apart tabs for providing projections extending from said guide elements in a plane at right angles to the direction of movement of said movable wall member;
- and
- the tubular portion of said movable wall member having circumferentially extending slots embracing said tabs with a relatively tight clearance in the direction of movement of said movable wall member and a relatively loose clearance in a plane at right angles to the direction of movement of said movable wall member.
