Abstract
PURPOSE: To improve pump efficiency and to prevent pulsation by providing the inside wall of a pump air chamber of the same shape as that of a diaphragm, and providing a space part acting as an accumulator from the discharge valve disc side in the thick walled part of said inside wall and the discharge valve disc.
CONSTITUTION: When a diaphragm 38 starts a suction stroke, a suction valve disc 39 which is grasped at one end with a root part 37 and a flange part 38a and is made free at the other end part opens a suction line 41, and a discharge valve disc 40 which is grasped at one end with the root part and a spacer 47 and is formed at the other end part as such a free end as to move into an air conduction passage 48 closes, so that air is introduced through the suction line into a pump air chamber 43. In the stage of discharging, the compressed air is forced into the conduction line by the diaphragm deforming to an M shape in section. At this time, the air acts in such a way as to force the discharge valve disc having elasticity into the space part 49 formed to the same shape as that of the diaphragm and utilizing the thick walled part 37a of the root part, thereby suppressing the generation of pulsation.
