  • Patent number: 7357113
    Abstract: A baffle plate configuration of an internal combustion engine according to a first embodiment of the invention is provided below a rotational member arranged on or near a crankshaft and prevents the rotational members and lubricant in a pan from interfering each other. The baffle plate includes a preventing portion that is provided at an end portion of the baffle plate located in the side that is opposite, in the axial direction of the crankshaft, to the side where a larger amount of lubricant returns to the pan. The preventing portion prevents piston pumping air generated above the baffle plate from entering a space below the baffle plate through the end portion of the baffle plate.

  • Patent number: 5102108
    Abstract: A vibration-damping device with hydraulic damping has a base body, a cylindrical holder secured to the base body, and an outer cylinder press-fitted within the cylindrical holder. A vibration-damping rubber body provided with a main liquid chamber enclosing a damping liquid is disposed within the outer cylinder, and retains an inner cylinder. A thin rubber wall is disposed between the outer cylinder and the vibration-damping rubber body, and defines an auxiliary liquid chamber with the vibration-damping rubber body. This auxiliary liquid chamber communicates with the main liquid chamber by way of a throttled passageway. The cylindrical holder has a rib-like projection which radially outwardly project therefrom, and extends in a circumferential direction thereof. This projection defines a groove along an inner surface of the cylindrical holder.
