Compound electromagnetic valve, high pressure pump and apparatus for controlling high pressure pump

摘要

An electromagnetic control valve has a passage (62b) for conducting fluid. An electromagnetic actuator (46, 48, 50) generates an electromagnetic force. A main valve body (54) opens and closes the passage (62b) in accordance with the electromagnetic force generated by the electromagnetic actuator (46, 48, 50). A bypass (54b) is formed in the main valve body (54). A sub valve body (52) opens and closes the bypass (54b) in accordance with the electromagnetic force generated by the electromagnetic actuator (46, 48, 50). The electromagnetic force generated by the electromagnetic actuator (46, 48, 50) is adjusted such that the sub valve body (52) is opened and closed while the main valve body (54) closes the passage (62b). <IMAGE>
