Abstract

PURPOSE: To extend serviceable life and to maintain stable compression efficiency of diaphragm pump by providing cooling chamber between diaphragm and drive section for cooling heat generated in and around diaphragm.
CONSTITUTION: Fresh air is sucked from small chamber 8 into cooling chamber 9 disposed between diaphragm 4 and drive section 7, and discharged from cooling chamber 9 through clearance 10 around drive shaft 6 in response to up-and-down motion of diaphragm 4. Since diaphragm 4 and drive shaft 6 are cooled by cold air flowing into and out of the cooling chamber 9 as above described, temperature of diaphragm 4 and drive shaft 6 will never be undesirably raised. Therefore, diaphragm 4 is not deformed or deflected by heat effect, so that compression efficiency can be stably maintained at all times, and service life of diaphragm itself can be remarkably extended.
