  • the actuator 2000 including the solenoid pump of the present invention constitutes a solenoid pump which serves to pump the fluid for the operation of the actuator 1100 and at the same time serves as a valve to change the direction of the fluid, thereby operating the actuator. It does not require a separate motor, pump and valves, and the piping configuration for the flow path is simple, so that a compact configuration is possible, and thus there is an advantage that it is easy to apply to a narrow space for the pipe and part configuration for the flow path configuration.

Inlet is stored under pressure.
  • a portion of the fluid that is pumped from the left to the right of the actuator 1100 is stored in the accumulator 1700 without passing through the solenoid pump 1000.
  • the right side of the solenoid pump 1000 is in a low pressure state and the left side is in a high pressure state.
  • the fluid flows along the hydraulic line 1600 on the right side, joins the fluid sucked from the right side of the actuator 1100, and passes the solenoid pump 1000 to the left side.

Abstract

La présente invention se rapporte à une pompe solénoïde et à un actionneur comprenant celle-ci. Plus spécifiquement, la pompe solénoïde comprend un carter ; une bobine d'entraînement qui est enroulée sur l'intérieur du carter et fixée à celui-ci ; un piston-plongeur magnétique qui est formé sur l'intérieur de la bobine d'entraînement et renferme un clapet de retenue ; une paire de bobines de direction qui sont disposées des deux côtés de la bobine d'entraînement et sont enroulées sur le carter et fixées à celui-ci ; et des poussoirs qui sont placés sur l'intérieur des bobines de direction, le clapet de retenue situé dans le piston-plongeur étant ouvert et fermé par les poussoirs de manière à commander la direction d'écoulement de fluide, ce qui permet d'envoyer le fluide dans deux directions. De plus, l'actionneur fonctionne par réception du fluide de pression et possède un ou plusieurs orifices d'entrée et de sortie, l'actionneur comprenant la pompe solénoïde, dont les tuyaux d'entrée et de sortie sont respectivement raccordés aux orifices d'entrée et de sortie de l'actionneur. Par conséquent, l'actionneur peut avoir une structure simple et compacte comme l'actionneur n'a besoin ni de moteur, ni de pompe ni de clapet supplémentaires pour fonctionner.
