    Abstract: A cylinder head for supporting and lubricating hydraulic valve lifters comprises a head member having a deck face adapted for mating with an engine block. The head member has a bottom face which is approximately perpendicular to the deck face. A plurality of sockets are formed in the head member and are adapted to receive a hydraulic valve lifter. A one-way gallery is formed in the head member above the sockets. The one-way gallery is parallel to a horizontal plane of the engine block when the head member is mated therewith. The one-way gallery is adapted to communicate with the valve lifters. A one-way passage is formed in the head member. The one-way passage has a gallery end which communicates with the one-way gallery and a supply end which is above the gallery end. A supply passage is formed in the head member. The supply passage has one end which communicates with the supply end and another end which communicates with a block port in the mating face. The block port is below the one-way gallery. The block port registers with a fluid passage in the engine block which can contain pressurized fluid.

    Abstract: An arrangement for changing the valve timing of an internal-combustion engine has a camshaft, which can be rotated relative to a shaft driving it. The camshaft has a phase converter with a piston which is hydraulically acted upon on both sides. In the camshaft, an axial recess is arranged in which an inserted pipe separates two spaces from one another. An on/off valve fed from the oil circulating system, in one position, via one of the spaces, supplies the piston with pressure oil so that this piston is axially shifted into a first end position and in the process rotates the camshaft. In a second position, the piston, by way of the second space is axially pushed back by pressure oil.

    Abstract: A V-type DOHC engine has first and second banks. The end of the cylinder row in the first bank on one end of the engine retracts from that of the cylinder row in the second bank. A first camshaft in each bank is driven by the crankshaft by way of a first transmission mechanism which is disposed on said one end of the engine, and the first and second camshafts in each bank are connected by a second transmission mechanism which is disposed between the first transmission mechanism and the cylinder row of the bank. The end portion of the first camshaft in the first bank on said one end of the engine is supported by a pair of bearings one disposed between the first and second transmission mechanisms and the other disposed between the second power transmission mechanism and the cylinder row in the first bank. The end portion of the second camshaft in the first bank on said one end of the engine is supported by a bearing disposed between the second transmission mechanism and the cylinder row in the first bank. The end portion of each of the camshafts in the second bank on said one end of the engine is supported by a bearing disposed between the first and second transmission mechanisms.

    Abstract: A drive cam follower operatively connected to an engine valve and a free cam follower capable of becoming free relative to the engine valve are adjacently disposed and adapted to impart in mutually different modes of operation in response to said engine valve rotation of a cam shaft. A connection change-over mechanism is provided between the cam followers and is capable of changing-over the interconnection and disconnection thereof, and resilient biasing means is provided between the free cam follower and the engine body for resiliently urging the free cam follower toward the cam shaft. The resilient biasing means comprises an urging piston slidably received in the engine body for abutment against the free cam follower, and a spring arrangement interposed between the urging piston and the engine body to resiliently bias the urging piston in a direction to abut against the free cam follower. The spring arrangement may comprise series-related springs having different spring constant with one of the springs having a non-linear load characteristic. A vent opening and a lubrication arrangement are provided to facilitate operation of the piston. The urging piston is provided, at its end closer to the free cam follower, with an abutment formed with a smaller diameter to abut against the free cam follower. This facilitates assembly of the resilient biasing means to the engine body, and makes it possible to dispose the resilient biasing means in proximity to a pivoting point of the free cam follower.

    Abstract: A hollow cam shaft of the type wherein lubricating oil is distributed to the cam portions includes a rod member positioned inside the shaft pipe member and spaced from the inner pipe surface by shaft end members and guide strips to form a reduced, annular volume to be filled with oil during engine start-up. The method of making the hollow cam shaft includes forming the rod member from a resinous material by injection molding, using a removable mold positioned in the pipe through-hole, and, in a preferred embodiment, flowing the resin through the mold cavity and into a recess located in the distal shaft end member, which recess has an enlarged portion for capturing the hardened resin rod end and facilitating mold removal.
