INDUCTION PATH - Tokyo Gas Co., Ltd.

Title:

INDUCTION PATH

Document Type and Number:

Japanese Patent JP3779090

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide an induction path which leads the gas being the target of measurement to a sensor in condition that needless substance such as rubbish, dust, etc., are removed properly, and also does not produce pulsation in sensor output even in a high flow rate region.
SOLUTION: This induction path is equipped with narrow passages 31-35 for raising the flow velocity of gas, and sedimentation chambers 21-25 forming hollow rectangular parallelepipeds for settling the needless substance in gas. The outlet of the narrow passage is opened, being biased to either the right or the left of one sidewall of the sedimentation chamber, and the outlet for the gas from the sedimentation chamber is opened in the sidewall on the side farther from the outlet of the narrow passage out of the sidewall vertical to one sidewall where the outlet of the narrow passage is opened, and also the position of it opening is set in a position separated enough from the sidewall opposed to the previous one sidewall. Hereby, the gas passes in a wide range within the sedimentation chamber, changing its flow direction by 90° until it gets out of the sedimentation chamber after its entry, so the place of sedimentation of needless substance is widened, and the sedimentation chamber is utilized effectively.
