Abstract
A housing includes a spool hole that receives a separated-type spool including a first and a second spool separated from each other in an axial direction of the separated-type spool. The first spool allows a first supply/discharge passage to communicate with either a pump passage or a tank passage. The second spool allows a second supply/discharge passage to communicate with the other pump passage or the tank passage. The housing includes: a first pilot chamber faced by an end surface of an opposite side of the first spool from the second spool; and a second pilot chamber faced by an end surface of an opposite side of the second spool from the first spool. A portion of the spool hole between the first spool and the second spool forms a third pilot chamber. The housing includes a pilot passage that communicates with the third pilot chamber.
