Abstract: An internal combustion engine has one or more engine cylinders (12) within which fuel is combusted and a pair of cylinder valves (14, 16) spring-biased (22, 24) closed but open in unison to place the respective cylinder in flow communication with one of an intake and an exhaust. A bridge (34) bridges ends of the pair external to the cylinder and has a spherically concave depression (42) in a face that is opposite a face that bears against the ends of the pair. The depression is located intermediate locations at which the ends of the pair bear against the bridge. A pivot foot (44) has a spherically convex surface (46) seated with substantial conformity in the depression and a flat surface (48) opposite the spherically convex surface. The flat surface of the pivot foot abuts a flat surface (50) of a rocker (30) that when rocked acts through the pivot foot and bridge to open the respective pair of valves.

Abstract: Apparatus for modifying engine valve lift to produce an engine valve event in an internal combustion engine comprises actuation means (100) for operating at least one exhaust valve (300a or 300), and control means (50) for moving the actuation means (100) between its inoperative position (0) and operative position (1). In the inoperative position (0), the actuation means (100) is disengaged from the at least one exhaust valve (300a or 300), and in the operative position (1), the actuation means (100) holds open the at least one exhaust valve (300a or 300) to produce the modified engine valve lift for the engine valve event, which includes an engine braking event (10). The actuation means (100) includes a motion limiting means for controlling movement of the actuation means (100) between the inoperative position (0) and the operative position (1), which occurs after the at least one exhaust valve (300a or 300) is actuated by the normal exhaust valve lifter (200). The actuation means (100) also includes a lash adjusting system for setting a lash (132) between the actuation means (100) and the at least one exhaust valve (300a or 300). The actuation means (100) further includes mechanical linkage means for transmitting load generated by the engine valve event to a housing (125). The mechanical linkage means include at least one system selected from the group consisting of: a rotatable device, a slidable device, a ball-locking device, and a toggle device. The actuation means (100) can be integrated into a valve bridge (400) and other valve train components, such as a rocker arm, wherein a plunger (136) is slidably disposed between the inoperative position (0) and the operative position (1). The control means (50) comprises at least one means selected from the group consisting of: hydraulic means, mechanical means, electric means, magnetic means, and a combination thereof.

Abstract: A novel device for controlling the compression pressure of an internal combustion engine is disclosed.The combustion chamber of each cylinder of the engine is divided into two virtual spaces, a gas exchange space and a control space. The intake and exhaust valves move in a plane substantially perpendicular to the cylinder centerline and open into the gas exchange space.The position of a preferably toroidal volume control slider determines the control space volume and subsequently, the geometrical compression ratio of the engine. At least one actuation cam bidirectionally drives said control slider, by means of a slot and captive roller arrangement.The device further comprises actuator means to rotate the cam to a predetermined angular position, as a function of engine load.Thus, the device of the invention is capable of maintaining a constant compression pressure, under varying load, by altering the geometrical compression ratio of the engine.
