Figure 9-3.—Typical fluid-pressurized reservoir. threaded  openings  for  connecting  fittings  and components.  Figure  9-4  shows  several  components installed in lines leading to and from the reservoir; however,  this  may  not  be  the  case  in  actual installation. The air relief valve, bleeder valve, and soon,  may  reinstalled  directly  on  the  reservoir. Because  the  reservoir  is  pressurized,  it  can normally  be  installed  at  any  altitude  and  still maintain  a  positive  flow  of  fluid  to  the  pump. Figure 9-4.—Air-pressurized reservoir. Some   air-pressurized   reservoirs   also   have direct contact of fluid to gas. These reservoirs are installed in large systems and may be cylindrical or rectangular in shape. They contain an oil level indicator,  a  pump  inlet  or  suction  line  connection, a  return  line,  a  gas  pressurization  and  venting connection, and a drain line connection or a drain plug.  These  reservoirs  are  pressurized  by  air  from the  ship’s  service  air  system  or  nitrogen  banks. These   reservoirs   are   found   on   board   aircraft carriers and submarines. ACCUMULATORS An  accumulator  is  a  pressure  storage  reservoir in which hydraulic fluid is stored under pressure from  an  external  source.  The  storage  of  fluid under  pressure  serves  several  purposes  in  hydraulic systems. In some hydraulic systems it is necessary to maintain  the  system  pressure  within  a  specific pressure range for long periods of time. It is very difficult  to  maintain  a  closed  system  without  some leakage, either external or internal. Even a small leak can cause a decrease in pressure. By using an accumulator, leakage can be compensated for 9-3
