PROBLEM TO BE SOLVED: To provide a pressure pump device capable of reducing a load of a pump motor and suppressing noise generated by the variation of the load, a liquid pressure feeding system for a liquid jetting device, and a liquid jetting device.;SOLUTION: The pressure pump device 33 comprises the pump motor 45 as a drive source, a reciprocating member 56 moving reciprocally based on the drive force of the pump motor 45 and a pump 46 which exhausts pressurized air from a pump chamber 54a generated by the increase/decrease of the volume in the pump chamber 54a formed in the device by the reciprocal movement of the reciprocating member 56. In this case, a coil spring 60 (energizing member) is provided which energizes the reciprocating member 56 to the reciprocating direction being the compressing direction for reducing the volume of the pump chamber 54a.;COPYRIGHT: (C)2007,JPO&INPIT
