An electromagnetic vibrational diaphragm pump comprising an electromagnet portion having an electromagnet arranged in a frame, a vibrator which is supported in the electromagnet portion and equipped with a magnet, diaphragms with a large diameter and diaphragms with a small diameter which are successively connected with both ends of the vibrator, and the pump casing portions of the diaphragms with a large diameter and diaphragms with a small diameter which are fixed on the both end portions of the electromagnet portion, wherein the left and right pump casing portions have pump chambers respectively corresponding to the diaphragms with a large diameter and diaphragms with a small diameter. Medium pressure (about 50 to 200 kPa) can be generated.

Electromagnetic vibrating type diaphragm pump

An electromagnetic oscillating type pump for oscillating diaphragms connected to an oscillator through electromagnetic oscillation of the oscillator with magnetic body by utilizing magnetic interaction between an electromagnetic portion comprising one or a plurality of iron cores and the magnetic body. A frame portion of resin mold is formed by molding resin on an outer surface of the electromagnetic portion. It is possible to obtain electromagnetic oscillating type pumps capable of decreasing manufacturing costs and of exhibiting high acoustic insulating effects.

Electromagnetic oscillating type pump and method for manufacturing the same

An iron core comprising an outer yoke, side poles disposed on both end portions of the outer yoke, and a center pole disposed between the side poles, wherein a magnetic path of polar portions of the center pole is formed as an open-circuit. There can be restricted for short-circuiting of magnetic flux of permanent magnets and thrust of an oscillator disposed at an air gap formed between electromagnets can be improved.

Iron core and electromagnetic driving mechanism employing the same

For positioning iron cores ( ) provided as part of the electromagnetic portion ( ), an iron core positioning tool ( ) is optionally provided, and in some embodiments is included as part of the electromagnetic portion ( ) and disposed at an inner peripheral portion of the electromagnetic portion ( ).

Household apparatus for preventing dental calculus and periodontosis

Diaphragm pump

A silencer assuming a shape of a sealed container in which an air reservoir is formed in a flow path from an suction inlet to an discharge outlet, wherein the air reservoir connected to the discharge outlet is provided with an exhaust valve mechanism for exhausting back-flowing air to the discharge outlet through external pressure. Since an exhaust valve mechanism for exhausting air which flows back to the discharge outlet owing to external pressure from, for instance, an air bag is provided, air can be rapidly exhausted from the air bag also in case actuation of the pump is terminated. Air pressure of the airbed can be promptly adjusted to perform adjustment of pressure of air bags or to prevent damages thereof.

Silencer and electromagnetic vibrating type pump employing the same

An electromagnetic valve which opens and closes passages for fluid by moving movable valve elements by means of attraction of an electromagnet includes movable valve elements having fluid passages and disposed inside a cylindrical electromagnet. The movable valve elements are disposed in the fluid passage inside the electromagnet so that supply and exhaust of fluid and switching between two directions can be performed.
