  "textContent": "A high-pressure pump (P) for use in a fuel injection system for diesel engines is provided which includes a plunger (21) slidably disposed within a chamber (11) formed in a pump housing (1) to define a pressure chamber (23) whose volume is changed according to sliding movement of the plunger (21), a check valve (4) disposed within a fluid inlet line extending from an inlet port (14) to the pressure chamber (23), and a solenoid valve (6) disposed within the fluid inlet line upstream of the check valve (4). The check valve (4) establishes fluid communication between the inlet port (14) and the pressure chamber (23) during a fluid suction operation wherein the fluid is sucked into the pressure chamber (23), while blocking the fluid communication between the inlet port (14) and the pressure chamber (23) during a fluid feeding operation wherein the fluid sucked into the pressure chamber (23) is pressurized and discharged from an outlet port (33). The solenoid valve (6) controls a flow rate of the fluid sucked into the pressure chamber (23) through the check valve (4). This pump structure is compact in size, consumes less electric power, and is capable of feeding a desired quantity of fuel into the engine accurately.",
