Title:
圧力制御装置および燃料供給装置
Document Type and Number:
Japanese Patent JP5792589
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure control device and a fuel supply device, capable of enhancing the responsiveness in changing the fuel pressure than ever before, enhancing the calculating accuracy of the switching time of the fuel supply pressure, and improving the fuel consumption.SOLUTION: The pressure control device 32 has a fuel pressure control valve 50 and a fuel selector valve 70, wherein the fuel selector valve 70 includes a bobbin 71 to form a fuel flowing part 82, a valve element 73 to make reciprocating motions for opening and closing the fuel flowing part 82, a solenoid coil 72 wound on the bobbin 71 and attracting the valve element 73 to the valve open position, and an energizing means 76 to energize the valve element 73 from the valve open position to the close position. The displacement amount of the valve element 73 with respect to the change amount of the load applied to the valve element 73 by the energizing means 76 in the first displacement section from the valve close position to the predetermined displace position is greater than the displacement amount of the valve element 73 with respect to the change amount of the load acting on the valve element 73 in the second displacement section which follows the first displacement section.
