Abstract

PURPOSE: To raise the durability of an air pump having oscillators with four degrees of freedom, by providing pistons which are moved in connection with a pair of oscillators and valves which are moved in connection with another pair of oscillators and providing a hermetic chamber 3 which is surrounded by the pistons and the valves.
CONSTITUTION: When the pistons 6a, 6b and the valves 9a, 9b are moved back at the same phase, air flows into the hermetic chamber 3 from a passage 7b. When the pistons 6a, 6b and the valves 9a, 9b are moved forth, the air in the hermetic chamber 3 is pressurized by the pistons. At that time, the valve 9a is opened from a passage 10a and the valve 9b is closed on a passage 10b. Therefore, the air is discharged from the hermetic chamber to a passage 7a. Because the pump employs no bellows, it has a high durability and can be made compact.
