<p>The regulator (1) has a pin diaphragm including discharge-holes with different diameter, and a sealing disk arranged in a low pressure region in an overhead coverage. A differential piston is arranged in a piston chamber, and separates a front surface (54) from a pressurized rear region of the piston chamber. The rear region is connected with a flow-off-region by a control channel, and a spring force acts on the differential piston in a direction of a front region. An acoustic signal is triggered by shifting the differential piston against the spring force.</p> |
