US 6,048,171 A · Bleed valve system

Abstract

The invention is a valve system particularly useful as a bleed valve system in a gas turbine engine. The valve system includes a valve ring or partition (44) that bounds a plenum (52). The valve ring has a set of two or more fluid flow regulating apertures (46), and one or more chains (60L, 60R) of metering plates (56). Each metering plate is pivotably supported relative to one of the apertures (46) to regulate fluid flow through the aperture. A coupling system that includes a series of transfer links (76) extending between neighboring metering plates successively conveys pivotal motion and angular orientation from each metering plate to the successive metering plate in the chain. An actuation system (90) includes a drive system (94) responsive to an actuator (92) for governing the angular orientation of the metering plates.

Dependent claims

A valve system for regulating fluid flow from a plenum, comprising:

a partition having a set of flow regulating apertures therein, the partition forming a boundary of the plenum;
a plurality of pivotably supported metering plates, each metering plate cooperating with one of the flow regulating apertures to regulate fluid flow therethrough;
a coupling system successively coupling together the metering plates to form one or more chains of metering plates, each metering plate being a member of one of the chains;
and
an actuation system for governing the angular orientation of the metering plate members of each chain.
