Abstract
A seal assembly includes first and second segments spaced from a frame and defining between each other an elongate lateral gap. A plurality of radially adjoining leaf seals bridge the lateral gap between the segments and are supported by a plurality of spaced apart pins, with each pin having an enlarged head on one side of the frame and a root on an opposite side of the frame fixedly joined to a bottom one of the leaf seals. A compression spring is disposed around each of the pins between the frame and a top one of the leaf seals for urging the top leaf seal toward the bottom leaf seal to seal flow radially therebetween and between adjacent support pins, and for urging the bottom leaf seal in sealing contact with the first and second segments to seal flow radially therebetween through the lateral gap.
Claims10
A seal assembly for an annular gas turbine engine comprising:
- a stationary frame;
- a first segment spaced radially from said frame;
- a second segment spaced radially from said frame, and spaced laterally from said first segment to define an elongate lateral gap G.sub.1 therebetween;
- a plurality of radially adjoining leaf seals bridging said lateral gap G.sub.1 ;
- a plurality of spaced apart pins supporting said leaf seals and extending radially through said frame, each having an enlarged head on one side of said frame, and a root on an opposite side of said frame fixedly joined to a bottom one of said leaf seals, said pins extending slidingly through the remainder of said leaf seals;
- and
- a plurality of compression springs each disposed in compression between said frame and a top one of said leaf seals for urging said top leaf seal toward said bottom leaf seal to seal flow radially therebetween and between adjacent ones of said support pins, and for urging said bottom leaf seal in scaling contact with said first and second segments to seal flow radially therebetween through said lateral gap G.sub.1.
