    摘要: There is provided a variable valve apparatus including: a plurality of rocker arms; a coupling pin disposed in a housing hole of the rocker arm closer to one side; a release pin disposed in a housing hole of the rocker arm closer to the other side; a pressing member; a transmission member; and a push-back member disposed so as to push back the transmission member from the other side. The pressing member is configured to push the coupling pin into the housing hole of the rocker arm closer to the other side to couple the plurality of rocker arms. The transmission member is configured to push back the coupling pin into the housing hole of the rocker arm closer to the one side to release a coupling of the plurality of rocker arms.

    摘要: The disclosure relates to a roller tappet for a high-pressure fuel pump. The roller tappet includes a housing that accommodates a cam contact roller next to a drive-side annular face of the housing. A bridge piece sits on an inner lateral surface of the housing, after the cam contact roller, as viewed from the drive-side annular face. An outer end face of the bridge piece has a rest for a pump piston. A separate adapter bolt protrudes from the rest beyond the output-side annular face of the housing; an end face of the adapter bolt, remote from the bridge piece, serves as a direct rest for the pump piston. An annular disc sits next to the output-side annular face of the housing, and the bore of said annular disc surrounds and retains the adapter bolt.

    摘要: A valvetrain for an internal combustion engine includes a camshaft, an electromagnetic latch assembly, a rocker shaft, and a rocker arm assembly. The rocker arm assembly may include a cam follower configured to engage a cam mounted on the camshaft as the camshaft rotates and a rocker arm configured to rotate on the rocker shaft. The electromagnetic latch assembly may include a pin translatable between a first position and a second position and an electromagnet that causes the pin to actuate. The movement of the pin may provide mode switching for a switching rocker arm, a cylinder deactivating rocker arm, or an engine brake rocker arm. The electromagnet is powered by a circuit that passes through the rocker shaft. The electromagnet may be mounted to the rocker shaft. Running the circuit through the rocker shaft allows the electromagnet to be powered with wiring that remains stationary.

    摘要: A yoke-type phaser is disclosed having a drive member and a driven member rotatable about a common axis and coupled to one another by means of a yoke that is movable, in a plane normal to the common axis, to vary the relative phase of the drive and driven members, by interaction between at least two contact elements and a contoured surface, one of (i) the contact elements and (ii) the contoured surface being connected for rotation with the drive member and the other being mounted on the yoke, each contact element comprising a roller in surface contact with a part-cylindrical recess in a carrier, wherein the carrier of at least one of the contact elements is either appropriately sized or adjustably mounted, to set the clearances between the rollers and the contoured surface.
