Abstract
Official abstract text for this publication.
A plate-like flow sensor is located in a bypass passage such that a front-to-rear direction of the flow sensor is substantially along a width direction of the bypass passage. The flow sensor divides a flow from its upstream into a first flow, which passes on its front side, and a second flow, which passes on its rear side. The bypass passage has a bent portion in which the first flow and the second flow merge on a downstream side of the flow sensor. A flow deflection unit changes a turning quantity of at least one of the first flow and the second flow such that a turning quantity of the first flow and a turning quantity of the second flow are substantially conformed in the bent portion.
First claim
Opening claim text (preview).
What is claimed is: 1. A flow detection device comprising: a housing forming a bypass passage configured to receive a part of air flowing through a duct; and a flow sensor located in the bypass passage, wherein the flow sensor is substantially in a plate shape and located such that a front-to-rear direction of the flow sensor is substantially along a passage-width direction of the bypass passage, the flow sensor being configured to divide a flow from an upstream side into a fi…
