Abstract: A first-type passage switching valve is provided in an oil supply line connecting a friction element to an N/H type pressure control valve and a second-type passage switching valve is provided in another oil supply line connecting another friction element to an N/L type pressure control valve. A working-pressure output valve outputs a hydraulic working pressure to each of the first-type and the second-type passage switching valves. The first-type passage switching valve changes its communication condition from a first communication state connecting the friction element and the pressure control valve with each other to a second communication state connecting the friction element and a drain side with each other, or vice versa. The second-type passage switching valve changes its communication condition from a first communication state connecting the friction element and the pressure control valve with each other to a third communication state connecting the friction element and a hydraulic pressure source with each other, or vice versa.

Abstract: A housing is placed at an inside space of a case to be installed on a vehicle. The housing includes: a housing plate portion configured to contact a case plate portion of the case; and a receiving space located on one side of the housing plate portion which is opposite to the case plate portion. An electric motor is placed at the receiving space and is configured to output a torque. The housing includes: a housing ventilation hole that extends through the housing plate portion and communicates between an outside space of the housing and the receiving space; and a breathable filter that is placed on a side of the housing ventilation hole, at which the case plate portion is placed, to cover the housing ventilation hole, while the breathable filter is configured to perm it a gas to pass through the breathable filter.

Abstract: A main locking mechanism locks a phase at a main locking phase, at which an intake valve is closed at timing later than a bottom dead center, by inserting a main locking member into a main locking hole. A sub locking mechanism locks a phase at a sub locking phase advanced more than the main locking phase by inserting a sub locking member into a sub locking hole. A movable body disposed in the main locking hole reciprocates between an open position and a blocking position of the main locking hole. During a warm start of an engine, a driving source maintains the movable body at the open position at which the inserting of the main locking member into the main locking hole is maintained. In contrast, during a cold start of the engine, the driving source drives the movable body to the blocking position at which the main locking member is removed from the main locking hole.

Abstract translation: 主锁定机构通过将主锁定构件插入主锁定孔中而将主相锁定相位锁定在主锁定阶段，在主锁定阶段进气阀在比下止点更时刻关闭。 子锁定机构通过将副锁定构件插入副锁定孔中而将锁定相位锁定在主锁定相以上。 设置在主锁定孔中的可移动体在主锁定孔的打开位置和阻挡位置之间往复运动。 在发动机的暖启动期间，驱动源将可动体保持在保持主锁定构件插入主锁定孔的打开位置。 相反，在发动机的冷启动期间，驱动源将可动体驱动到主锁定构件从主锁定孔移除的阻挡位置。
