Document Type and Number:
WIPO Patent Application WO/2008/001666
Kind Code:
A1
Abstract:
[PROBLEMS] An inexpensive reed valve not requiring fluorocarbon resin coating nor
an elastic member at a valve seat section. [MEANS FOR SOLVING PROBLEMS] A valve
body (24) to which a reed-shaped valve body (23) is attached is formed of a ferrous
metal material such as a cold roll steel sheet (SPC sheet) with a thickness of about
2 to 3 mm. In the forming process, a valve hole (25) and a screw hole (24H) are prepared
by punching. A bolt (26) is screwed to the screw hole (24H) to fix the valve body
(23) and a stopper (28) to the valve body (24). When the valve body (23) is not bent,
it airtightly closes the valve hole (25), and when the valve body (23) is bent by
pressure, the valve hole (25) is opened and secondary air flows through the valve
hole (25).
