Abstract:
A spool valve includes a valve block; a first spool, which is mounted onto one side on the inside of the valve block so as to be moved forward and backward in the lengthwise direction and includes a first notch formed on the outer circumferential surface, for controlling the connection between a first pump flow path and a first cylinder flow path through the first notch which is aligned with the first pomp flow path and the first cylinder flow path formed on the inside of the valve block, when moved according to a change in stroke; and a second spool, which is mounted onto the other side on the inside of the valve block so as to be moved forward and backward in the lengthwise direction and includes a second notch formed on the outer circumferential surface, for controlling the connection between a second cylinder flow path and a first tank flow path through the second notch which is aligned with the second cylinder flow path and the first tank flow path formed on the inside of the valve block, when moved according to a change in stroke.

Claim (Index 5):
The spool valve according to  claim 4 , further comprising:\n a third spool cap coupled to the valve block, connected to the third spool, and providing a third port through which a pilot pressure is applied to change the stroke of the third spool; and a fourth spool cap coupled to the valve block, connected to the fourth spool, and providing a fourth port through which a pilot pressure is applied to change the stroke of the fourth spool.
