Abstract
A guide projecting into a bladder is provided on a plug of a vessel body. A cup-shaped sensor is slidably provided on the guide, and an element for actuating a switch is provided on the cup-shaped sensor. The cup-shaped sensor is caused to slide along the guide by the bladder deformable in accordance with change in the pressure of liquid within the accumulator, so as to actuate the switch.
