Abstract:
1. A pressure detector comprising: a body having a flow passage therein through which a fluid flows in a flow direction from an inlet end of the flow passage to an outlet end of the flow passage, a sensor chamber provided in the body and in which a pressure sensor is arranged, a through hole that extends at an angle to the flow direction, from the flow passage to the sensor chamber, wherein one end of the through hole extends to the flow passage to intersect the flow passage, and a pressure transmitting body comprising a shaft disposed in the through hole and displaceable along an axial direction in the through hole, the pressure transmitting body being capable of transmitting a pressure of the fluid to the pressure sensor, one end of the pressure transmitting body extending in the through hole to the intersection of the one end of the through hole with the flow passage, the one end of the pressure transmitting body being constantly exposed to the fluid and having an outer diameter which is substantially the same as the diameter of the one end of the through hole, whereby no dead space is present at the one end of the through hole.
