DEVICE FOR SPOOL'S DISPLACEMENT

摘要

A device for measuring spool displacement is provided. The device for measuring spool displacement comprises: an adapter of which one side is coupled to a pilot valve; a piston housing of which one side is coupled to the other side of the adapter; a port coupled to the other side of the piston housing, wherein a hydraulic fluid of the pilot valve flows; a joint of which one side is coupled to the port, wherein an accommodating hole to which a displacement sensor can be coupled is formed in the other side; and a piston arranged to slide by penetrating through the adapter and the piston housing, and interlocked with movement of a spool of the pilot valve to be arranged to be equally moved.
