The present invention pertains to a solenoid pump and an actuator including the same. More specifically, the solenoid pump includes a housing; a driving coil which is wound on the inside of the housing and fixed thereto; a magnetic plunger which is formed on the inside of the driving coil and incorporates a check valve; a pair of direction coils which are provided at both sides of the driving coil and wound on the housing and fixed thereto; and pushers which are provided to the inside of the direction coils, wherein the check valve provided in the plunger is opened and closed by the pushers so as to control the flowing direction of fluid, thereby sending the fluid in two directions. In addition, the actuator operates by receiving pressure fluid and has at least one or more inlet and outlet ports, wherein the actuator includes the solenoid pump, of which inlet and outlet pipes are respectively connected to the inlet and outlet ports of the actuator. Therefore, the actuator may be formed in a simple and compact structure as the actuator does not need an additional motor, pump or valve for the operation thereof. |
