<p><P>PROBLEM TO BE SOLVED: To provide a device for detecting pressure of secondary supply air, capable of detecting secondary air pressure inside a solenoid controlled valve 2 without measuring errors. <P>SOLUTION: On a coil assembly 4 of the solenoid-controlled valve 2, a male connector 9 which conserves a terminal 6 for driving the solenoid controlled valve and a terminal 7 for pressure detection en bloc, and a sensor mounting section 10 for unitizing a pressure sensor 3 and the solenoid controlled valve 2 are integrally installed. By arranging a solenoid coil 5, a yoke 41 for forming a magnetic circuit with the solenoid coil 5, a stator core 42 and a moving core 43 on the out side of secondary air paths 31, 32 in the solenoid valve 2, and arranging the pressure sensor 3 for detecting the secondary air pressure in the solenoid valve 2 on the reverse side of the magnetic circuit side, regarding the secondary air paths 31, 32, the heat conduction from the engine exhaust tube, in which the high temperature exhaust gas is flowing, is unlikely to be transmitted to the pressure sensor 3. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
