Regulator Tank Piping
The piping leads from the high pressure air manifold, by way of a regulating valve, a gauge and a relief valve, to a manifold in the control room. The manifold has four connections, one to each half of the regulating tank and one to each half of the regulating bunker. Piping from each lead runs to port and starboard and connects to the vent line of the related tank. By opening one or more of the manifold valves, which are all stop valves, and opening the regulating valve, air is admitted to either half of either tank. If, in addition, valves on the seawater piping to the tanks are opened, a differential pressure between one half and other of one tank, or between half of one tank and half of the other tank, will cause a flow of water which provides compensation for a list, trim compensation, or both simultanoously. Futher, it is physically possible to blow to sea via the regulating tank flood valve.
Negative Blow Piping
This piping from the high pressure air manifold connects, by way of a regulating valve, pressure gauge and relief valve to the negative tank inboard vent line. By opening the port or starboard hull valve in the vent line, it is possible to put pressure on either half of the negative tank and, if the flood valve is then opened, to blow the negative tank to sea.
Hydraulic Air Piping
This piping leads from the high pressure air manifold, by way of a 205 to 48 atmosphere reducing valve (2920 to 682 psi), a filter, a water separator and a stop valve, to the top of the air-oil flasks which stor oil ubder pressure for the hydraulic system. The air is used to provide an initial pressure for the hydraulic pumps to operate against, and as a source of make-up air for the flasks if and as necessary.
Windless Air Piping
This piping leads from the torpedo high pressure air manifold in the forward torpedo room, by way of a filter, a parallel arrangement of a 205 to 4 atmosphere (2920 to 57 psi) reducing valve, a gauge and a relief valve, to an air motor which operates on a multiple screw basis similar to that of an IMO pump. Opening of the air supply valve, either in the forward torpedo room or air deck, starts the motor.
