<P>PROBLEM TO BE SOLVED: To provide a pump which is driven by wave power and can stably take out energy irrespective of water level. <P>SOLUTION: The pump includes: a body; a first flow passage, a second flow passage, a supply flow passage and a discharge flow passage disposed on the body; a first piston; a second piston; and a connection member. The body separates an external water region from an internal water region, the first flow passage is located in water, communicates the external water region with the internal water region, with the first piston inserted therein, the second flow passage is opened to the internal water region side, with the second piston inserted therein, the supply flow passage is connected to the second flow passage and supplies fluid to the second flow passage, the discharge flow passage is connected to the second flow passage and discharges the fluid from the second flow passage, and the connection member is connected with the first piston by a first spindle freely rotatably, is connected with the second piston by a second spindle freely rotatably and is connected with the body by a body spindle freely and rotatably. <P>COPYRIGHT: (C)2013,JPO&INPIT |
