Air filter restriction indicator gauge |
摘要 |
A low cost air filter restriction indicator gauge for use in conjunction with an internal combustion engine can be achieved by both simplifying individual part configuration and reducing overall part count. More specifically, a simplified design can be achieved by utilizing a one piece base cap which includes a locking extension and reset button integral therewith. By having this part injection moldable, it is easy to fabricate and lower in cost as a complex locking pin assembly can be eliminated. Further, the low cost device can be further enhanced by providing a two color visual indicator which displays one color when the device is in its reset position and a second color when the device is in its locked or set position.
