Abstract
The present invention discloses a fluid level indicator (100) actuated by tape spring (3), preferably of the “constant-force” type, in connection with the piston (6) of the hydraulic actuator (1), so as to keep the load constant throughout the entire stroke of the piston (6). The spring tape (3) has the function of making the connection to the piston (6), providing the flexibility of a spring, in addition to indicating through a graduation, the level of the hydraulic system fluid.
Claims9
Fluid level indicator for a hydraulic reservoir, the indicator comprising a fluid level indication window, wherein:
- the indicator comprises a spring tape operationally connected to a piston of the hydraulic reservoir;
- wherein a movement of the piston along the stroke thereof determines a corresponding degree of distension of the spring-tape;
- wherein the spring tape comprises a graduated scale, the graduated scale indicating the fluid level of the hydraulic reservoir;
- wherein the graduated scale is visible through the fluid level indication window.
