CONSTANT RATE EXHAUST VALVE APPARATUS FOR HEMODYNAMOMETER

摘要

PURPOSE:To enable application without changes in the exhaust rate for a long time by preventing the tearing of an end part of a slit. CONSTITUTION:A constant rate exhaust valve apparatus is so formed that the amount of an opening of a slit 2 provided on an exhaust valve body 1 is regulated by pressing the exhaust valve body 1 to adjust an exhaust rate. The exhaust valve body 1 is provided with a thick part 11 near both ends of the slit 2 so that the thickness of the exhaust valve body 1 is increased partially near the end part of the slit 2 with the thick part 11 to enhance a tearing strength at the part. This prevents the tearing of the ends of the slit 2 even when a repeated stress works on both the ends of the slit 2.
