Abstract

PURPOSE: To improve the retraction of diaphragms and to simplify the constitution of a diaphragm pump by disposing a rod penetrating opposing partition walls of pump heads in a non-locking condition with the diaphragms.
CONSTITUTION: Pump chambers 15, 15' of a pair of pump heads 14, 14' housing diaphragms 18, 18' are fixedly formed in a face-to-face relation, while a rod 17 is provided to penetrate opposing side or partitioning walls of the chambers 15, 15'. This rod 17 is acturated by the diaphragms 18, 18' according to their opposing fluid feeding operation and is provided in a non-locking condition with the diaphragms 18, 18'. Since the space between the rod 17 and the partition walls is so narrow that the moving amount of the fluid between the pump chambers 15, 15' is easily deminished by providing a sliding part with an O-rings.
