Hydraulic fluid of a reservoir is supplied to the fluid pressure chamber (11) through a first communication path (22), grooves (27e), and the space between the outer lip (27c) and the bottom wall (26a). As mentioned above, the inner lip (27b) has only the sealing function, while the outer lip (27c) has both the sealing function and the pumping function and ensures sufficient fluid supply by the grooves.

This invention comprises a method for applying a polyurethane solution to the lens headlights of automobiles. The solution is contained within a customized cylindrical application container that includes a container for storing the polyurethane and an applicator head. The applicator head fastens to the base by depressing it over a curved outer lip of the base until it is secured. The cap itself is hollow and is topped by an angled base having a hole that allows the solution to be dispensed. To assure the smooth and controlled dispersal of the solution, a rectangular sponge is attached to the top of the angled base. This sponge regulates the application of the solution to the covers of headlights and taillights of automobiles and similar vehicles. Upon application, the solution actively restores the covers by binding and filing in scratches and other abrasions on the surface. This results in a smooth surface that ensures the clear filtration of light, thereby aiding the transmission of light through the lens.
