Patent ID: 7360433

Claim:
A fluid system/pressure indicator combination comprising: a fluid system having a fluid pathway extending between a fluid pump and a filter element; a housing having an interior fluid portion in fluid communication with the fluid pathway, said housing having a cover with an opening; an axially displaceable pressure communicator having an actuator within the housing, said communicator being at least partially in fluid contact with the fluid system; a fluid diaphragm fluidly separating the actuator from the fluid system; an indicator spring exerting an axial pressure on the pressure communicator; a projectable indicator having an actuator engagement surface and at least one portion which is projectable through the opening to an exterior of the housing; and said indicator spring exerting a biasing pressure on the indicator such that when the projectable actuator and actuator engagement surface are not in engagement, a portion of the projectable indicator is projected through the opening to an exterior of the housing.
