PURPOSE: To improve delivery efficiency by installing two intermediate pressure pistons, and periodically driving two high-pressure pistons by these intermediate pressure pistons alternately, while installing a film member or a fluid separate means to separate two fluids in both inward and outward chambers from each other. CONSTITUTION: This high-pressure aggregate which is provided with an inlet opening 487 to be connected to an outlet opening 488 of an intermediate pressure generating unit consisting of a pump unit 19 with a power source 401, has a control unit 17 to be rotatively driven by a fluid motor 97 being driven by a return flow via two reduction gears 467 smf 466, and this control unit feeds two cylinders alternately with an intermediate pressure fluid from an opening 91 and two fluid passages 472 and 473, periodically driving two pistons 8 and 9 alternately in these cylinders. These intermediate pressure pistons 8 and 9 drive both small diametral high pressure pistons 5 and 6. Each of these high pressure pistons 5 and 6 is installed in a housing 464, imbibing the fluid through both inlet/out parts 64 and 65, and they discharge it as a high pressure fluid. |
