US 2026/0210499 A1 · LIQUEFIED-GAS DELIVERY SYSTEM

Abstract

The liquefied-gas delivery system includes a reciprocating pump apparatus (3) for pressurizing liquefied gas and boil-off gas in a storage tank (1). The reciprocating pump apparatus (3) includes a cylinder (14) having a gas pressurization chamber (10) and a liquid pressurization chamber (11) therein, a piston (17) disposed in the cylinder (14), and an actuator (18) coupled to the piston (17) for reciprocating the piston (17). The piston (17) is located between the gas pressurization chamber (10) and the liquid pressurization chamber (11). The piston (17) has a gas pressurization surface (21) facing the gas pressurization chamber (10) and a liquid pressurization surface (22) facing the liquid pressurization chamber (11).
