Variable flow particle separating structure

A particle separating structure for use with a turbine engine comprising:

• a main housing comprising:
• an inlet;
• a cooling fluid outlet;
• a particle discharge zone located radially outwardly from said cooling fluid outlet;
• a first stop structure;
• and
• a biasing member;
• first swirling structure in said main housing for swirling cooling fluid passing through a first cooling fluid flowpath defined in said main housing;
• wherein:
• said first swirling structure is positionable in at least two positions, said positions based on an amount of cooling fluid entering said main housing through said inlet, a first position of said first swirling structure allowing cooling fluid to pass through said first cooling fluid flowpath and a second position of said first swirling structure allowing a first portion of cooling fluid to pass through said first cooling fluid flowpath and a second portion of cooling fluid to bypass at least a section of said first cooling fluid flowpath;
• said biasing member biases said first swirling structure toward said first stop structure such that said first swirling structure engages said first stop structure when in its first position;
• and
• the swirling of the cooling fluid effected by said first swirling structure causes particles in the cooling fluid to pass to said particle discharge zone while the cooling fluid passes out of said main housing through said cooling fluid outlet.

A cooling fluid distribution structure for use with a turbine engine comprising:

• a main housing comprising an inlet and a cooling fluid outlet;
• and
• cooling fluid structure in said main housing for distributing cooling fluid passing through said main housing, said cooling fluid structure being positionable in at least:
• a first position wherein said cooling fluid structure allows cooling fluid to pass through a first cooling fluid flowpath defined in said main housing;
• and
• a second position wherein said cooling fluid structure allows a first portion of cooling fluid to pass through said first cooling fluid flowpath and a second portion of cooling fluid to bypass at least a section of said first cooling fluid flowpath, wherein said cooling fluid structure allows a greater amount of cooling fluid to pass through said main housing when in its second position than when in its first position.
