Abstract:
A variable valve lift apparatus may include an outer tappet body of which a latching portion connecting hole and an outer tappet body guide hole may be formed therewithin, an inner tappet body of which an inner tappet body guide hole may be formed therewithin and slidably disposed within the outer tappet body, a latching portion which may be disposed within the inner tappet body guide hole and selectively coupled to the latching portion connecting hole, a latching portion support pin which guides the latching portion along a longitudinal direction of the inner tappet body guide hole and may be connected to the inner tappet body, a hydraulic pressure chamber, and a plunger which may be slidably disposed in the outer tappet body guide hole and selectively inserts the latching portion into the latching portion connecting hole according to the hydraulic pressure supplied from the hydraulic pressure chamber.
Abstract:
The present invention relates to a variable tappet, and the variable tappet may include an inner tappet body of which a latching member connecting hole is formed thereto, a protrude portion formed to the latching member connecting hole, an outer tappet body which is disposed around the inner tappet body and slidable to the inner tappet body and a latching member which is disposed to the outer tappet body and selectively connected to the latching member connecting hole.
Abstract:
An apparatus for adjusting deviation of an engine and a continuously variable valve lift device including the same are provided. The apparatus for adjusting deviation of an engine includes an adjustment member connecting a rocker arm to plural output cams, respectively, to adjust lengths between the rocker arm and the output cams, respectively, so that the lengths become equal to or different from each other. The continuously variable valve lift device includes an eccentric cam shaft with eccentric cams installed on its outer periphery, a rocker arm rotatably installed on the eccentric cams to interlock with plural output cams, and apparatus for adjusting deviation provided on the rocker arm to adjust lengths between the rocker arm and the output cams so that the lengths become equal to or different from each other.
Abstract:
Blow-by gas supplied from a cylinder head cover is re-supplied to an engine through runners of an intake manifold via a channel portion in communication with a plenum of an intake system.
Abstract:
The present invention discloses a prosthetic implant and an insertion instrument for inserting the prosthetic implant between adjacent vertebrae. The prosthetic implant in accordance with the present invention includes a housing for being packed with bone chips, an inserting hole formed at a first end of the housing, through which an insertion instrument can be inserted, and a connection recess formed on inner surface of the housing around the inserting hole, on which the insertion instrument is stably placed. The insertion instrument in accordance with the present invention includes a connection member having a connection chip at a first end, a rotating means for rotating and returning the connection member at a predetermined angle. In accordance with the present invention, the insertion instrument can be separated from the prosthetic implant by rotation of only one time after the prosthetic implanted is completely inserted, so that the operation process of implanting the prosthetic implant is easy and safe. Further, the prosthetic implant in accordance with the present invention safely and stably fixed between the adjacent vertebrae because projections are formed at the upper end and lower end of the prosthetic implant respectively.
