<p>PURPOSE:To enable operation at high speed by tilting the upmost front stage reciprocating pump of each pump group be of a forced valve type, and dividing equally the phase of each reciprocating member. CONSTITUTION:Two pump groups 10a and 10b are of a forced valve type wherein an inlet valve 20 is installed on a reciprocating member 14. The reciprocating member 14 is in a phase lag by the angle of 18 deg. from a crank shaft 16 wherein when one pump group is in the exhaust stroke, the other group is in the suction stroke. The pumping chambers 12b and 12c at the rear stage side discharge the fluid pressurized by the pumping chambers 12a and 12b at the front stage side after it has been additionally pressurized, the pressure at an outet port 50 as the discharging pressure from the pumping chamber 12c is thereby extraordinarily high.</p> |
