Cold valve for exhaust gas recycling apparatus

Patent ·
OSTI ID:7290472
A control valve is described for an exhaust gas recycling system with two devices for converting operating parameters of an internal combustion engine into mechanical regulating movement. The housing has an inlet and an outlet for the exhaust gas, a stationary partition dividing the housing into two chambers, and two perforated plates, each in one of the chambers between the partition and the inlet and the outlet. The plates are mounted on two rotatable axles such that a hole in the respective perforated member can be moved into and out of alignment with the opening in the partition to open and close the opening and control a flow of exhaust gas through the valve. Each of the axles is adapted for coupling to a different one of the converting devices of the recycling apparatus.
