Abstract: A valve actuating system for actuating at least one valve of an engine includes an improved mechanism for varying the timing and/or lift of the valve. The mechanism uses two adjacent rockers that cooperate with two adjacent cams of a camshaft. In one operating condition, movement of a first rocker is transmitted to the valve through the second rocker and in another operating condition only the movement of the second rocker is transmitted to the valve. The rockers preferably cooperate with cams having different lifts. The lift of the cam driving the first rocker preferably is greater than the lift of the cam driving the second rocker.

Abstract: A valve drive mechanism is provided for an internal combustion engine, especially a four-stroke engine in a power chain saw. The implement housing is spanned by a front handle, the tubular grip of which is adjacent to the cylinder head of the engine and extends from one longitudinal side of the implement to the other longitudinal side thereof. A rocker arm of a valve control is pivotably mounted on the cylinder head between the ends of the rocker arm, with the rocker arm being pivotable about a pivot axis disposed transverse to the rocker arm. Push rods of a control mechanism engage one end of the rocker arm to actuate a poppet valve, on the valve stem of which the other end of the rocker arm acts. To be able to guide the tubular grip close to the center of gravity of the implement, the longitudinal axis of the rocker arm is disposed approximately parallel to the adjacent portion of the tubular grip.

Abstract: An adjustment screw assembly (10) having an adjustment screw (11) engaged to a rocker arm (14) of a combustion engine (12) is disclosed. The adjustment screw (11) comprises a lower member (26) and a vertical member (28) wherein the vertical member (28) threads to the rocker arm (14) and the lower member (26) secures pivotally and rotatably to the vertical member (28) forming a pivotal connection (31). The pivotal connection (31) has a male connector (38) which snap fits through an engagement lip portion (46) of a female socket (35) and is thereby held together for combustion engine assembly purposes. Once the adjustment screw (11) is assembled and placed within the combustion engine (12), internal springs (24) of the engine (12) resiliently hold and secure the lower member (26) to the vertical member (28).

Abstract: A rocker support assembly for a motorcycle internal combustion engine. The assembly comprises a pair of rockers positioned in spaced relation from each other, a breather housing, and a pressure-responsive member. The housing at least partially defines an inlet aperture, an outlet aperture, and a passage in fluid communication between the inlet aperture and the outlet aperture. The passage is positioned substantially between the rockers. The pressure-responsive member is disposed in the passage and is operable in response to pressure differences in the passage to permit or inhibit fluid flow through the passage from the inlet to the outlet. A filter element is disposed within the housing such that substantially all fluid flowing from the inlet aperture to the outlet aperture passes through the filter element.

Abstract: A cam follower (1) is proposed, which is made from a sheet metal material, and has a profile that is U-shaped in cross-section. In the area of its one end (6), its side walls (2) taper conically. At the same time, straps (7) for guiding a shaft end of a gas exchange valve are provided on an underside (5) of the cam follower (1) as an extension of the side walls (2) and are bent by 180° to fit on the underside (5) in the area of the end (6). A cam follower (1) of this type is made in a simple way, has an excellent guide possibility for the shaft end of the gas exchange valve, and has a smaller mass with a smaller mass moment of inertia than cam followers that have been used until now.

Abstract: A resilient retainer is disclosed for a rocker arm coupling joining a valve assembly to a rocker arm assembly in an internal combustion engine. The rocker arm coupling includes a first coupling member having a socket for receiving a ball extending from a second coupling member. The resilient retainer consists of unitary polymeric material including a resilient mounting portion and a resilient restricting portion. The resilient mounting portion is engageable with a recess delineated within the first coupling member for resiliently securing the resilient retainer.
