摘要： A coupler for translating a rotational force, including first and second rotational elements. The first rotational element defines a first pocket. The second rotational element is in axial alignment therewith and defines a second pocket facing the first pocket. The first pocket and the second pocket define a dampening chamber therebetween that varies in volume based on the overlap thereof. A fluid is positioned in the dampening chamber. A portion of the fluid is dispelled from the dampening chamber when the first rotational element rotates relative to the second rotational element and decreases the volume of the dampening chamber.

摘要： A valvetrain for translating force and oil between a valve and intermediate member of an engine, including a rocker, a shaft, and a recess. The rocker has an inner surface, a pad for engaging the valve, a socket for engaging the intermediate member, a socket port defined in the surface, and a socket channel extending from the socket port to the socket. The shaft has a bearing surface for supporting the rocker, a channel spaced from the bearing surface, a feed port in the bearing surface, and a feed channel extending from the feed port to the channel. The rocker rotates between: closed, with the socket port and feed port aligned; and open, with the socket port spaced from the feed port. A recess is disposed in the bearing surface adjacent to the feed port and extends to a base aligned with the socket port when the rocker is open.

摘要： A four-stroke engine includes a case (1) which is comprised of a first case half (3) and a second case half (8) connected with each other at a parting plane which goes through centerline of a crankshaft and is perpendicular to centerline of a cylinder (7). A first bearing seat (19) is divided into a first upper bearing seat half (4) and a first lower bearing seat (9) at the parting plane. A second bearing seat (20) is divided into a second upper bearing seat half (5) and a second upper bearing seat half (10) at the parting plane. The first upper bearing seat half (4) and the second upper bearing seat half (5) are integrally molded on the first case half (3), and the first lower bearing seat half (9) and the second lower bearing seat half (10) are integrally molded on the second case half (8). An outer side surface of the first case half (3) and a side cover (21) form a valve-operating chamber (26) for receiving a valve-operating mechanism (30).

摘要： The clearance between the outer peripheral surface of an annular portion of a cage and the inner peripheral surface of each of rib portions of outer-ring split pieces is set to be smaller than the clearance between the radial end surface of a projection portion of the cage and the inner peripheral surface of each of body portions of the outer-ring splitpieces . When a centrifugal force due to engine rotation acts upon the cage, the inner peripheral surface of each of the rib portions of the outer-ring split pieces touches the outer peripheral surface of the annular portion of the cage before the inner peripheral surface of each of the body portions of the outer-ring split pieces touches the radial end surface of the projection portion of the cage, Thus, the radial displacement of the cage canbe prevented in good time.

摘要： A valve operating mechanism is described for an internal combustion engine in which at least one valve (14) of an engine cylinder is operated by two cams (10,12). The cams (10,12) have respective cam followers (38,36) which are resiliently biased to remain in contact with the cams (10,12) at all times and which act on the valve (14) by way of a summation linkage (20,24) in such a manner that the displacement of the valve (14) at any instant is determined by a combination of the displacements of the two cam followers (38,36). In the invention, movement of each of the two cam followers (38,36) is transmitted to the summation linkage (20,24) by way of a respective one of two pushrods (28,30).

摘要： A rocker shaft unit (49) for an internal combustion engine comprises a rocker shaft (50), and a rocker shaft mount (49A). The rocker shaft (50) is configured to have a rocker arm (46) mounted thereto and to provide an axis (50A) of rotation for a pivot movement of the rocker arm (46). The rocker shaft mount (49A) is configured to displaceably mount the rocker shaft (50). The configuration allows varying the position of the axis (50A) of rotation by displacing the rocker shaft (50) during the pivot movement. In particular, the configuration may allow for a decoupling of an engine valve operation from a camshaft system.

摘要： Leakage of a liquid (e.g. a coolant and/or a lubricant) past a sleeve valve to a port in communication with a combustion chamber of an internal combustion engine can be prevented by use of a substantially ring-shaped seal, which can be carried on the sleeve valve or disposed on a stationary part of the internal combustion engine.

摘要： In a V-type engine (E), intake and exhaust rocker arms (71a, 72a, 71b, 72b) in each bank (B1, B2) are arranged in a substantially inverted-V-shape in a plan view, so that side end portions of corresponding intake and exhaust push rods (44a, 44b, 45a, 45b) are positioned adjacent to each other. Slipper portions (48) of first and second intake cam followers (42a, 42b) have end portions at one end along the axial direction of a camshaft (38), protrude respectively in the opposite directions to each other so that they face each other across an intake cam (38i) therebetween. Slipper portions (48) of first and second exhaust cam followers (43a, 43b) have end portions at one end along the axial direction of the camshaft (38), protrude respectively in the opposite directions to each other so that they face each other across an exhaust cam (38e) therebetween. This reduces the distance between the push rods (44a, 44b, 45a, 45b) in each bank to provide a compact valve-operating device.
