Hydraulic fluid reservoir`s e.g. brake fluid reservoir, liquid level detecting unit for motor vehicle, has float sliding along rod between upper and lower stops formed by ends of groove of rod, and having protrusion sliding in groove

摘要

The unit has a cylindrical rod (300) with an upper stop (306) at an end (308) and a lower stop at another end. A float (400) slides along the rod between the upper and lower stops. The float has a protrusion (404) sliding in a vertical groove (301) of the rod, extending partially along a length of the rod. An upper end (305) of the groove forms the upper stop and a lower end of the groove forms the lower stop for the float. Independent claims are also included for the following: (A) a hydraulic fluid reservoir having a detecting unit (B) a method for assembling a detecting unit.
