ABSTRACT:
An vent mechanism comprising an upper housing, a lower housing, a diaphragm comprising a diaphram contact contained between the housings, an upper contact, an insulator insulating the upper contact from the upper housing, and an internal ground wire between the diaphram contact and the lower housing.When used as part of a electrical circuit with an indicator, the diaphram senses oil vapor pressure build up. When a given level of pressure is obtained, the diaphram contact moves against the upper contact and the vent mechanism is grounded, completing the electrical circuit, enabling the indicator to function as intended.
