<p><P>PROBLEM TO BE SOLVED: To provide a solenoid pump smoothly discharging hydraulic liquid. <P>SOLUTION: The solenoid pump includes a coil moving a moving core 13 to a fixed core side by an electromagnetic force, a spring member separating the moving core 13 moved to the fixed core side from the fixed core, a pump housing 11 at least partially becomes the fixed core, a pressure chamber 120 formed in the pump housing 11, a suction valve 130 opening when sucking the hydraulic fluid into the pressure chamber, a discharge valve 140 opening when discharging the hydraulic fluid from the pressure chamber 120, and a piston 111 provided in the pump housing 11 and increasing/decreasing the capacity of the pressure chamber 120. The pressure chamber 120 is formed on the opposite side to a side on which the moving core 13 is disposed over the piston 111. A communication port 130a of the suction valve 130 and a communication port 140a of the discharge valve 140 are opened into the pump housing 11 facing the pressure chamber 120, and the spring member is disposed on the outside of the pressure chamber 120. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
