Diaphragm type check valve and method for manufacturing the same |
| abstract |
The present invention relates to a diaphragm type check valve, such as a micro valve for a micro pump device, which may be formed of a slit diaphragm bonded to the inside of a valve tube, and a method of manufacturing the same. A bump and/or reverse leak stop in the diaphragm can increase the cracking pressure of the valve. A push rod may be used to pre-load the valve diaphragm to increase the cracking pressure. |
