Patent number: 10280907Abstract: The present invention prevents a gas generated by evaporating a low-temperature liquid from remaining in an internal space of a booster pump and enhances efficiency of discharge and suction. A reciprocating booster pump 50 includes a cylinder 41, a piston 42, a suction check valve 65, and a discharge check valve 62. The cylinder 41 has a suction port 55 and a discharge port 56. The suction port 55 suctions a low-pressure, low-temperature liquid to an inside. The discharge port 56 boosts the low-temperature liquid and discharges the low-temperature liquid to an outside. The piston 42 reciprocates in an internal space 43 of the cylinder. The suction check valve 65 opens and closes a suction flow passage 64 between the internal space and the suction port. The discharge check valve 62 opens and closes a discharge flow passage 61 between the internal space and the discharge port.Type: GrantFiled: July 5, 2017Date of Patent: May 7, 2019Assignee: MITSUI E&S MACHINERY CO., LTD.Inventors: Kazushige Ohta, Makoto Kounosu

Patent number: 10208724Abstract: A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator and configured to reciprocate in an axial direction, the reciprocating pump being configured to suck the fuel when the boosting piston moves in a first direction and configured to boost and eject the fuel when the boosting piston moves in a second direction; and a controller configured to control driving of the linear actuator so as to adjust an amount of the fuel ejected from a boosting cylinder per reciprocating time by adjusting a ratio of a fuel ejection time and a fuel suction time of the reciprocating pump without changing the reciprocating time of the boosting piston in accordance with a load of the internal combustion engine. The adjustment adjusts a stroke length of the boosting piston and a moving speed of the boosting piston in the second direction.Type: GrantFiled: April 13, 2016Date of Patent: February 19, 2019Assignee: Mitsui E&S Machinery Co., LTDInventors: Makoto Kounosu, Seiichi Kitamura, Renzo Kanda

Patent number: 10012195Abstract: A fuel supply device includes: a linear actuator; a reciprocating pump having a boosting piston driven by the linear actuator, configured to axially reciprocate, and configured to alternately repeat suction of the fuel and ejection of the fuel more boosted than the fuel at a time of suction by reciprocation of the boosting piston; and a controller to control driving of the linear actuator. When reciprocation amplitude of the boosting piston is A (A>0) and a reciprocating cycle time is T, the controller controls the linear actuator so a maximum value of an absolute value of acceleration when the reciprocating pump sucks the fuel with an absolute value of speed of the boosting piston increasing is smaller than A·(2?/T)2, and so a maximum value of the absolute value of the acceleration of the boosting piston when the reciprocating pump ejects the fuel is larger than A·(2?/T)2.Type: GrantFiled: April 7, 2016Date of Patent: July 3, 2018Assignee: Mitsui Engineering & Shipbuilding Co., Ltd.Inventors: Makoto Kounosu, Seiichi Kitamura, Renzo Kanda
