Abstract: A valve system for an engine including a valve resting mechanism provided between an engine valve and a valve lifter supported by a cylinder head. The valve resting mechanism can place the engine valve into a resting state. The valve resting mechanism has a pin holder which includes a sliding hole having an axis perpendicular to the axis of a valve lifter, and an insertion hole for allowing a valve stem to pass therethrough. The pin holder is slidably fitted in the valve lifter. A slide pin is slidably fitted in the sliding hole, with a hydraulic force and a spring force applied to both ends of the slide pin. A containing hole is coaxially connectable to the insertion hole, and a rotation stopping means for stopping axial rotation of the slide pin is provided between the pin holder and the slide pin.

Abstract: In a tappet for use in an internal combustion engine, a tip is fitted in an engage bore between the top wall of the tappet and an engine valve shaft. The tip has a chamfered portion over which a circumferential projection is pressed by a punch so as to fix the tip in the engage bore firmly. A caulking groove is formed by the punch around the engage bore on the top wall. Owing to the chamfered portion of the tip, a cracking is prevented at the bottom of the groove.

Abstract: In an internal combustion engine with a cylinder (1), the cylinder head (2) has four valves (3, 4) inclined towards each other and arranged to be radially aligned with respect to the combustion chamber, pairs of the valves being operable by a common camshaft (6) by means of conical cams (7). To make it possible to use such a valve control for high rotational speeds, too, bucket type tappets (8) are displaceably mounted between the radially aligned valves (3, 4) and the conical cams (7) in the cylinder head (2).

Abstract: A lash adjuster can include a hydraulic lash assembly, a mechanical lash assembly, and a check assembly. The hydraulic lash assembly can include a body, a top plunger, a leak down plunger, and the check assembly between the body and the leak down plunger. The mechanical lash assembly can be between the top plunger and the leak down plunger. The mechanical lash assembly can include a shim abutting the top plunger, a spacer, and a spring pressing against the spacer and the shim to form a gap between the top plunger and the leak down plunger. The lash adjuster can include the spring pressing directly against the spacer and directly or indirectly against the shim.

Abstract: A hydraulic valve brake for a hydraulic valve drive of an internal combustion engine is provided. The valve brake includes a housing with a housing wall and with a housing base, and includes a piston which moves axially in the housing and one end side of which, together with the housing wall and the housing base, delimits a hydraulic pressure chamber and the other end side of which actuates a gas exchange valve. The housing wall is perforated in the region of the pressure chamber by one or more overflow openings, the opening cross sections of which are controlled by a control edge, which delimits the end side at the pressure chamber side, of the piston. In this case, it is the intention for the axial distance (h) between the control edge of the piston, when the latter is fully retracted into the housing, and the housing base to be set by a spacer of predetermined thickness (d).

Abstract: A fast acting valve train system for valve deactivation is provided that includes an actuator together with a switchable rocker arm. The actuator, controlled by the engine control unit and mounted to a structural housing, contains an actuator pin that retracts or extends facilitating either a deactivation or reactivation valve event. The switchable rocker arm is a two arm design that includes cam side and valve side arms that are coupled together with a locking mechanism assembly that interfaces with the actuator pin. The system is capable of fast switching times to meet the increased demands of cylinder deactivation systems.

Abstract: A switchable finger follower, including an inner lever and an outer lever. The outer lever is mounted for pivoting movement to the inner lever. A coupling device is located on one of the inner or outer levers and has a coupling pin arranged to move between a locking position, in which the inner and outer levers are connected together for movement in an activation direction, and an unlocked position, in which the inner lever is pivotable relative to the outer lever. A coupling projection is located on the other of the inner or outer lever. The coupling pin engages beneath a coupling surface of the projection in the locking position, and a stop surface of the projection contacts a second stop surface on the one of the inner lever or the outer lever. The second stop surface is located on a removable shim that is replaceable for lash adjustment.

Abstract: A method for setting lash on a switching rocker arm assembly includes providing a rocker arm having (i) an outer arm having a first outer side arm and a second outer side arm, the outer arm defining an opening, (ii) an inner arm disposed between the first and second outer side arms, (iii) a roller follower that selectively engages a cam, the roller follower mounted about a bearing axle that extends through the opening. A zero lash shim is inserted into a gap defined between the bearing axle and the outer arm at the opening. The rocker arm is installed into the valvetrain with the master tip cap. Lash is measured between the cam and the roller follower. The rocker arm and the master tip cap is removed. A select fit valve tip cap is installed based on the master tip cap and the measured lash.

Abstract: The present invention provides a shim for a valve drive mechanism which is interposed between a pad surface of a rocker arm and a stem end surface of a valve. The shim includes a ship top surface that is contacted by the pad surface. The shim top surface is rotated about a center thereof to be cut, is provided with a center hole at the center thereof, and is shaped such that the pad surface does not contact an intersection line between an inner peripheral surface of the center hole and the shim top surface when the rocker arm is swung.
