Patent ID: 7958722

Claim:
A valve device comprising: a control valve for manipulating a communication between a first fluid channel and a second fluid channel; a pressure sensor for detecting pressure in the first fluid channel; and an inlet pipe partially defining the first fluid channel and partially defining a pressure transmission chamber for leading fluid from the first fluid channel to a pressure detection face of the pressure sensor through an opening, wherein the pressure sensor is provided on a side face of the inlet pipe partially defining the first fluid channel, the pressure detection face is directly opposed to the first fluid channel, the pressure detection face is substantially in parallel with a first axis (A) of the first fluid channel, which first axis (A) is a center line of the inlet pipe, the control valve is provided at an intersection between the first axis (A) of the first fluid channel and a second axis (B) of the second fluid channel, and the pressure detection face is substantially in parallel with an imaginary plane including the first axis (A) and the second axis (B).
