Document Type and Number:
WIPO Patent Application WO/2013/047417
Kind Code:
A1
Abstract:
A solenoid valve in which a coil (96) that attracts an armature (80) is housed in a main body (70). A valve portion (82) that sits on/is lifted from a valve seat (74) is integrally formed with the armature (80). The valve seat (74) is interposed between a high-pressure passage (78) and a low-pressure passage (83). The high-pressure passage (78) and low-pressure passage (83) are blocked by the valve portion (82) being seated on the valve seat (74), and the high-pressure passage (78) and low-pressure passage (83) communicate by the valve portion being lifted from the valve seat (74). Through holes (86) are formed by boring the part of the armature (80) in which the flux from the coil (96) is small, and guide pins (102) which are fixed to the main body (70) are engaged in the through holes (86).
