Abstract:
An oil quantity adjustment device (1), provided with a valve unit (A) and a solenoid unit (B). The valve unit (A) has: a housing (2) having an inlet hole (20), an outlet hole (21), and a leak hole (22); a partition wall (3) for partitioning the outlet hole (21) and the leak hole (22), and sectioning a valve housing chamber (R) on the outlet hole (21) side, the partition wall (3) having a partition-wall-side through-hole (30); a valve (4) for partitioning the valve housing chamber (R) into an introduction chamber (Ra) and a pressure chamber (Rb), and having a valve-side through-hole (400); and a valve-urging member (50) for urging the valve (4). The solenoid unit (B) has a shaft (612) capable of opening/closing a leak passage (L2). The shaft (612) is capable of opening and closing the leak passage (L2) at the downstream side of the pressure chamber (Rb). When the shaft (612) closes the leak passage (L2), the valve (4) switches to a closed state in which the outlet hole (21) is closed.
