Abstract

PURPOSE: To increase the feeding rate of secondary air in compliance with the increase in VC negative pressure irrespective of revolutional speed of an air pump by interposing, in a pressure channel of a relief valve, a differential pressure regulator which operates upon application of pressures at two points in a secondary air channel and VC negative pressure as input signals.
