Abstract
A liquid pressure-feed device having a reduced number of parts and a simple structure is provided. A snap mechanism has a pivot shaft supported within a closed vessel, a float arm and a sub-arm both adapted to rotate about the pivot shaft, a first shaft supported by the float arm, a second shaft supported by the sub-arm, and a spring mounted between the first and second shafts. A float is connected to the float arm and a change-over valve is connected to the sub-arm through a power transfer shaft. There is provided a stopper shaft supported within the closed vessel, there is formed in the float arm a window through which the stopper shaft extends and which restricts a rotational range of the float arm with floating of the float, and there is formed in the sub-arm a window through which the stopper shaft extends and which restricts a rotational range of the sub-arm with descent of the float.
