Abstract
A solenoid valve is mounted in the bore of a ferromagnetic journal. Mounting the solenoid valve in the journal conserves space on the firewall of a vehicle where the solenoid is typically located. Journal mounting also minimizes the length of the air line necessary to supply air to the solenoid valve. Use of a ferromagnetic journal as part of the magnetic circuit allows full use of the journal bore for the components of the solenoid valve. A leak vent path is provided as well as a principal vent path in the flux flanges of the solenoid valve. The solenoid valve controls the flow of air through a seal which engages a rotating coupling of a clutch which operates a fan.
