Benefits of technology

This configuration reduces system complexity and weight by allowing a single actuator to control multiple valves, achieving precise airflow control while minimizing additional components, thereby enhancing system efficiency and performance.

Problems solved by technology

Using a dedicated actuator for each valve to be controlled can support a wide range of control sequences between multiple valves; however, each actuator adds weight and complexity to the overall system.

Embodiment Construction

[0026]A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.

[0027]FIG. 1 schematically illustrates a gas turbine engine 20. The gas turbine engine 20 is disclosed herein as a two-spool turbofan that generally incorporates a fan section 22, a compressor section 24, a combustor section 26 and a turbine section 28. The fan section 22 drives air along a bypass flow path B in a bypass duct, while the compressor section 24 drives air along a core flow path C for compression and communication into the combustor section 26 then expansion through the turbine section 28. Although depicted as a two-spool turbofan gas turbine engine in the disclosed non-limiting embodiment, it should be understood that the concepts described herein are not limited to use with two-spool turbofans as the teachings may be applied to other types of turbine engines including three-spool a...

Abstract

An aspect includes an offset parallel valve system that includes a first valve body and a first valve disc operably disposed within the first valve body. The offset parallel valve system also includes a second valve body in parallel with the first valve body and a second valve disc operably disposed within the second valve body, where the second valve disc is laterally offset from the first valve disc. A linkage system is operably coupled to the first valve disc and the second valve disc. The linkage system includes an armature coupled to a grooved linkage member having a first groove and a second groove. The first groove delays movement of the second valve disc as the first valve disc rotates, and the second groove controls a rotation angle of the second valve disc.

Description

BACKGROUND[0001]The subject matter disclosed herein generally relates to flow control systems and, more particularly, to a method and apparatus for offset parallel valves with a linkage system.[0002]Pneumatic systems, such as airflow control systems on an aircraft, can use multiple valves with multiple actuators to control delivery of an airflow for various purposes. Components receiving the airflow may have different requirements for timing or conditions under which the airflow should be received. Using a dedicated actuator for each valve to be controlled can support a wide range of control sequences between multiple valves; however, each actuator adds weight and complexity to the overall system.BRIEF DESCRIPTION[0003]According to one embodiment, an offset parallel valve system includes a first valve body and a first valve disc operably disposed within the first valve body. The offset parallel valve system also includes a second valve body in parallel with the first valve body and ...
