    Abstract: A planetary rotor includes: a planetary gear engaged with a driving rotor and a driven rotor on an eccentric side; and a single sequence type planetary bearing having an outer ring held by the planetary gear, an inner ring supported by a planetary carrier in the radial direction and receiving a restoring force from an elastic component, and a plurality of spherical rolling elements interposed between the outer ring and the inner ring. The outer ring is arranged to form a rolling contact part in contact with the spherical rolling element on the eccentric side, with a contact angle to a specific side in the axial direction. A thrust-bearing part where the driving rotor is supported by the driven rotor on the specific side and on the eccentric side is located closer to a rotation center line of the driven rotor than the rolling contact part is.

    Abstract: When a lock demand of a camshaft phase occurs, a control mode of a hydraulic control valve s switched to a locking mode after an actual camshaft phase is controlled to a lock phase, and a lock pin (an inner pin and an outer pin) is moved to a lock position. Thus, the camshaft phase is locked at the lock phase, and a timing advance chamber and a timing retard chamber are made a state of communicating with each other through a back space. In this state, a locking time filling control is executed. In the locking time filling control, the control mode of a hydraulic control valve is switched to a filling mode, the hydraulic oil is supplied to a timing advance chamber, both of the timing advance chamber and the timing retard chamber are filled with the hydraulic oil, the back space is filled with the hydraulic oil, and thereafter the control mode of the hydraulic control valve is returned to the locking mode.

    Abstract translation: 当发生凸轮轴相位的锁定需求时，在实际凸轮轴相位被切换到锁定模式的液压控制阀s的控制模式被控制到锁定相位，并且锁定销（内部销和外部销）是 移动到锁定位置。 因此，凸轮轴相锁定在锁定相位，并且定时提前室和定时延迟室被制成通过后部空间相互连通的状态。 在该状态下，执行锁定时间填充控制。 在锁定时间填充控制中，将液压控制阀的控制模式切换为填充模式，将液压油供给到定时提前室，定时提前室和定时延迟室都用液压油 后部空间充满液压油，此后液压控制阀的控制模式返回到锁定模式。

    Abstract: A flowmeter includes a hollow housing, a first passage, a second passage, a detector, and a flat surface. The housing includes a first side wall and a second side wall and defines an inlet opening and an outlet opening that is defined in the first side wall. The first passage fluidly connects between the inlet opening and the outlet opening. The second passage branches off from the first passage. The detector is disposed in the second passage and configured to detect a flow rate of the target fluid flowing through the second passage. The flat surface is an outer surface of the first side wall and extends between an upstream end of the first side wall and the outlet opening along the main flow direction.
