  • Multiple displacement system for an engine
    Patent number: 7040265
    Abstract: A cylinder deactivation arrangement for an engine is provided. The arrangement includes an engine with main oiling circuit passages and lifter oil gallery control circuit passages formed internal to a cylinder block of the engine. The lifter oil gallery control circuit is arranged so as to provide an oil flow path internal to the cylinder block from the main oiling circuit to the deactivating lifter. A lifter is positioned in the cylinder block and arranged in fluid communication with the lifter oil gallery control circuit. A control valve is positioned in the cylinder block and arranged in fluid communication with the main oiling circuit and the lifter oil gallery control circuit. The control valve is arranged to allow selective fluid communication of oil from the main oiling circuit to the lifter oil gallery control circuit to selectively control actuation of the lifter.

  • Deactivating valve lifter
    Publication number: 20040244751
    Abstract: A valve lifter for an internal combustion engine comprises an outer body, an inner body and at least one pin. The inner body is movable with respect to the outer body, and the at least one pin is movable in response to hydraulic pressure into the groove to lock the outer body against movement relative to the inner body.
