摘要： A passive exhaust valve assembly includes an exhaust conduit or pipe section with a valve plate or vane member that can pivot within the interior section or volume of the exhaust conduit to regulate the flow of exhaust gases through the exhaust conduit. A flexible bumper element, such as a metal mesh pad, may be positioned on the interior surface of the exhaust conduit, such that an end portion of the valve plate may contact the mesh pad in the closed position. The bumper element may be disposed in a recessed pocket or depression and may be biased inward, such as with a spring, for the end portion of the valve plate to contact the bumper element as it moves toward the closed position, and thereby gradually reduce the closure speed of the valve plate to the closed position.

摘要： A method is of diagnosing a hydraulic machine which includes a rotor shaft, a cylinder, a piston forming a working chamber together with the cylinder, and a high-pressure valve and a low-pressure valve provided for the working chamber, and which is configured to perform conversion between rotational motion of the rotor shaft and reciprocal motion of the piston. The high-pressure valve includes a poppet valve including a seat and a poppet configured to be in contact with the seat from a side of a high-pressure line of the hydraulic machine. The method includes: a step of measuring a pressure of the working chamber in a state where the high-pressure valve and the low-pressure valve are closed; and a step of detecting a damage of the high-pressure valve on the basis of the pressure of the working chamber.

摘要： A valve device includes: a poppet 84 that is formed in a hollow shaft shape except for a leading end, has a tapered closure part 91 at the leading end and a side hole 95 passing through a wall of the hollow shaft-shaped part, and rotates around the shaft center thereof during opening and closing actions; and a valve seat having a sloped seat surface with which the closure part 91 of the poppet 84 comes into contact when closing the valve device. The closure part 91 of the poppet 84 or the seat surface of the valve seat, whichever has a higher hardness, has a cut mark of the opposite direction from a direction of rotation of the poppet 84 around the shaft center that occurs during the valve closing action.
