摘要： PROBLEM TO BE SOLVED: To improve supply responsiveness of oil pressure to retard and advance oil pressure chambers by preventing leaking of the oil pressure from a retard oil passage and an advance oil passage, and to improve control responsiveness of valve timing responding to change of an engine operating state.
SOLUTION: By selectively supplying and discharging hydraulic oil via the retard oil passage 18 and the advance oil passage 19 with respect to the retard oil pressure chamber 11 or the advance oil pressure chamber 12, a relative turning position of a vane member 9 is controlled to a retard side or an advance side with respect to a sprocket 1. Passage parts 18a, 19a of the retard oil passage and the advance oil passage are formed in an interior of a passage component 37 inserted into and held in a cylindrical support part 15a of a vane rotor 15, and seal members 41a, 41b carrying out sealing between an opening end of each passage part and inner circumference faces of the support member are fit into and fixed to a front and a rear of an outer circumference face of the passage component.

摘要： PROBLEM TO BE SOLVED: To provide a lock mechanism surely performing neutral lock by automatically returning to a neutral lock position from both directions of an advancing direction and a retarding direction.
SOLUTION: A variable camshaft phase device for an internal combustion engine comprises: a body 20 rotating together with a sprocket; a vane 26 varying a phase angle on a same rotary shaft with respect to the body 20 and rotating together with a camshaft; and a lock pin 46 fixing relative phase angle of the body 20 and the vane 26. The lock pin 46 is provided in such a manner that it is supported to move forward and backward along a pin shaft direction and to rotate around the pin shaft by a support surface 50 of a first engagement surface formed on the body 20, and is provided in such a manner that it engages with a second engagement part formed on the vane 26. A butting surface 52 butting on the lock pin 46 when the vane 26 rotates in the retarding direction is formed on the second engagement part, inclined to the pin shaft. A butted surface 58 opposed to the butting surface 52 and inclined to the pin shaft is formed on the lock pin 46.

摘要： PROBLEM TO BE SOLVED: To provide a device for adjusting the phase angle of a camshaft of an internal combustion engine that can return and lock a phase angle of a camshaft to an intermediate position under its own power by utilizing a fluctuating torque acting on a camshaft during the engine start, and has a structure with high usefulness and mass productivity. SOLUTION: A device for adjusting the phase angle of a camshaft of an internal combustion engine includes a first rotating body that rotates together with a camshaft, a second rotating body 6 that is provided coaxially relative to the first rotating body and adjustably in phase angle and rotates together with a sprocket, and a locking mechanism for locking the phase angle. The locking mechanism has a wedge member 16 in which a wedge-shaped portion is formed, and the first rotating body and the second rotating body have abutting faces 16d, 16c that abut the wedge member. An abutting face of at least either one of the first rotating body and the second rotating body is formed such that the distance from the center of rotation to the line of action of load acting on the abutting face is smaller than the distance from the center of rotation to the line of action of load on the abutting face.

摘要： PROBLEM TO BE SOLVED: To stably stack paper sheets longitudinally at a high speed by providing a guide means for guiding the paper sheets, a first rotation means providing such deformation as enhancing the longitudinal rigidity of the paper sheets, and a second rotation means biasing and pushing the paper sheets entering from the adjacent to the side of the guide means to a stack part. SOLUTION: A bill 1a from a previous stage passes through a position sensor 15 for detecting a position of the bill 1a, is pushed up by the rigidity of a sheet wheel 6 sandwiched and rotated by a stack and an opposite roller 4, 5, and deformed into an alternately recessed/projected waveform. While the bill 1a is deformed by the sheet wheel 6 after detached from the stack and opposite rollers 4, 5 along the stack guide 7, it is sent forward till its tip part is brought in contact with the front edge 3a of a stack part 3. Right after that, the bills 1a are collected to an stacked bill 1b side of the stack part by being forcedly beaten by an impeller 12 rotated by a stepping motor 14 and pressurized in their standing states along with the stacked bills 1b, and the stacked bills 1b are also held their standing attitude.
