Air directional control valve

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.
