ABSTRACT:
A fluid level indicating apparatus includes a piston and cylinder assembly which is located adjacent the surface of a body of fluid contained within fluid reservoir and includes openings to admit such fluid thereinto with the piston in one extreme axial position, and to vent air from the cylinder but restrict fluid flow therefrom during movement of the piston from the extreme axial position. The piston is connected by a link to a pivotally mounted level indicating plate which pivots in conjunction with pivotal movement of an actuator element (e.g. the hinged cap of the fluid reservoir closure) to a position indicating the level of fluid in the reservoir. The actuator element is releasably connected to the indicator plate in a manner to cooperate with the restriction of fluid flow from the cylinder upon piston movement to position the indicator plate at an appropriate level indicating position for any given fluid level within the indicating range of the apparatus.
