摘要： PROBLEM TO BE SOLVED: To provide a safety coupling which has an easy and cost-effective means so that high standards of safety and reliability can be achieved. SOLUTION: The safety coupling is provided with two coupling halves (5, 6) which can be tightly connected to each other in the axis direction by a clamping device in the axis direction, which face each other in the axis direction and work synergistically by a friction-engagement system. The clamping device of the safety coupling can be destroyed when both coupling halves(5, 6) are mutually rotated. The clamping device has a shaft(15), provided with a screw, which is engaged with mutually-separated supporting surfaces(19, 21)in the axis direction of both of the coupling halves(5, 6), and a return head(16). The return head(16) attached to the shaft is provided with two engagement areas which work synergistically with the coupling halves(5, 6) allocated each by a rotation-engagement system. Then the torsion head(16) is mutually separated by a targeted destruction point(22) and connects both of the coupling halves(5, 6) together by the rotation-engagement system. Thus the safety coupling can achieve high standards of safety and reliability by comprising a tensile engagement device coaxial with a coupling axis. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a hydraulic-operated device of an exhaust valve capable of accurately controlling a valve and solving the disadvantages that very large load is applied to both of a valve actuator and a hydraulic component so that a specified component rapidly wears away in an undesirable degree. SOLUTION: The hydraulic-operated device of the exhaust valve 2 in an internal combustion engine is provided with a valve pump 8 having a pressure chamber 30, and in the pressure chamber, a port 29 is selectively connected to a high pressure supply source for hydraulic fluid or a return pipe through a control valve. A service piston in the valve pump 8 separates the pressure chamber 30 from a hydraulic volume part communicating with a pressure chamber in a hydraulic actuator to a main shaft of the exhaust valve through a pressure conduit 6. A second service piston limits a flow of hydraulic fluid from the port 29 to the pressure chamber 30 at the start position.
