Title:

VALVE, FLUID APPARATUS AND FLUID SUPPLY APPARATUS

Document Type and Number:

WIPO Patent Application WO/2010/137578

Kind Code:

A1

Abstract:

Disclosed are a valve, a fluid apparatus and a fluid supply apparatus in which the valve can be opened/closed without using an active element and excessive supply can be prevented. Specifically disclosed is a valve which comprises a valve housing (10), a diaphragm (20) which divides the interior of the valve housing (10) into the first valve chamber (11) and the second valve chamber (12) and displaces with the pressure of fluid, a first opening (15) provided in the first valve chamber (11), a second opening (16) provided in the first valve chamber (11), and a third opening (17) provided in the second valve chamber (12). When a pump (4) is not driven, the force of the diaphragm (20) acting to the second valve chamber (12) side is larger than the force of the diaphragm (20) acting to the first valve chamber (11) side, and thereby the second opening (16) is sealed by the diaphragm (20). When the pump (4) is driven and the force of the diaphragm (20) acting to the first valve chamber (11) side becomes larger than the force of the diaphragm (20) acting to the second valve chamber (12) side, the first and second openings (15, 16) are interconnected by the diaphragm (20).
