摘要： PROBLEM TO BE SOLVED: To equalige the control operation and control the angle of rotation without shock by buffering the rotational position change of a cam shaft and a volume wheel incorporated therein relatively rotatably by a buffer means. SOLUTION: An inner part 14 is provided on the end of a cam shaft 1 of an internal combustion engine, and three radial webs 16a-16c are extended from the outer peripheral part of the inner part 14 at a distance of 120 deg., for example. The outer peripheral parts of the webs 16a-16c are brought into close contact with the inside surface of a volume wheel 18 where three webs 22a-22c are similarly extended inward. By the webs 16a-16c, 22a-22c, three volume chambers are respectively portioned into two pressure chambers 24a-24c, 25a-25c. The supply and discharge of a pressure medium to and from the pressure chambers are controlled through a control valve 39 to change the relative angle of the volume wheel 18 and the cam shaft 1, and the change of rotational position is hydraulically buffered by functioning a gap 43 at the tip of the web 16c as a buffer means.

摘要： PROBLEM TO BE SOLVED: To provide a device, which can be constituted simply and at a low cost, enables the change of a rotational position without fluctuation and changes the rotational position of a shaft relatively to a driving pulley. SOLUTION: Two pressure chambers to each other in an adjustment device 3 are always connected to a pressure medium pump 19 through control conduit pipes 16 and 17 respectively. Control valves 26 and 27 are arranged in the control conduit pipes respectively, and bypass connection sections 24 and 25 which are communicated to a pressure medium tank 28 can be formed by the control valves 26 and 27. Through this constitution, effective hydraulic clamping states or a tension state can be obtained in all operation positions and even during adjustment by always loading pressure to a pressure chamber working in the opposite direction, as a result, overlapping causing the fluctuation of changes in a rotary position is sufficiently eliminated.

摘要： PROBLEM TO BE SOLVED: To precisely adjust an oscillating-motor camshaft adjuster having a hydraulic valve having two working ports with little expenditure.SOLUTION: This invention relates to the oscillating-motor camshaft adjuster 4 having the hydraulic valve 3, which has two working ports A and B. These two working ports A and B each have a standard opening axially adjacent to one another and an opening for the utilization of pressure peaks as a consequence of camshaft alternating torques. A hydraulic pressure can be guided from a supply port to the working port A, B to be loaded, while the working port A, B to be relieved of pressure is guided to a tank port T. In order to also keep the control performance high in the case of internal combustion engines with very greatly fluctuating camshaft alternating torques, a position of the hydraulic valve 3 can be controlled proportionally, in which the pressure peaks of the working port A, B to be relieved of pressure are blocked relative to the supply port and the working port A, B that is to be loaded.

摘要： PROBLEM TO BE SOLVED: To provide a lock pin, namely a lock slider, characterized in that during running, it is caught certainly even at high angular velocity, in that it is also released from locking state exactly, in that it is manufactured easily, in that all torque can be transmitted from a stator to a rotor, and in that under drastic variation of load, it generates noise with play as little as possible.
SOLUTION: The regulator is characterized in that a sliding body consists of a first portion, namely an initial force transmitting member having a first diameter, and a second portion, namely a wedge-like fixing portion having a second diameter, in that at that time the first diameter is greater than the second diameter, in that two portions are arranged in the slider so that it may be prepared inside a housing opening in such a state that they are locked, in that the housing opening has a diameter greater than that of an initial force transmitting unit, and in that the technology can be solved by alternating a transmission of force between the initial force transmitting portion and the wedge-like fixing portion when in a locking process.
