A variable line 4 formed out of flexible material is arranged inside of the liquid tank 1. One end of the flexible line 4 is connected to the supply pipe 2 via a supply valve 21 opening only to the variable line 4 side. Another end of the flexible line 4 is connected to the delivery pipe 3 via a delivery valve 31 opening only to the delivery pipe 3 side. The pump structure is constructed to supply pressurizing force and depressurizing force to the liquid. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
