Abstract
A purge valve for a vehicle mounted fuel vapor recovery system is made up of a main housing and two end caps which snap fit together to seal and mount a computer controlled solenoid valve and a diaphragm controlled regulating valve. The housing is designed so that the required valve seats are integrally molded in the housing as are the various internal passages and chambers. A compression post formed on one end cap seats the solenoid assembly firmly against an abutment surface on the housing.
