Abstract:
A valve structure for a reversing flow catalytic converter for exhaust gases, the converter having a container which has a top end with a first port and a second port which are in fluid communication with each other so that the exhaust gases introduced into the first and second ports flows through a stationary catalytic material in the container, comprising:a valve housing including an intake cavity and an exhaust cavity, adapted to be mounted on the top end of the container, the intake cavity being adapted for connection of an exhaust gas pipe and the exhaust cavity being adapted for connection of a tail pipe;a valve component operably mounted in the valve housing for reversing gas flow through the stationary catalyst, the valve component being adapted to be moved between a first position in which the intake cavity communicates with the first port and the exhaust cavity communicates with the second port so that a gas flow passage is enabled through the stationary catalyst in a first direction, and a second position in which the intake cavity communicates with the second port and the exhaust cavity communicates with the first port so that a gas flow passage is enabled through the stationary catalyst in a second direction opposite the first direction.
