摘要： An engine valve system comprises two cams (10,12) mounted coaxially, a summation rocker (14) coupled to followers (16,18) of both cams and movable in proportion to the instantaneous sum of the lifts of the respective cams, and a valve actuating rocker (20) pivotably coupled to the summation rocker (14) and operative to open an engine valve (22) in dependence upon the movement of the summation rocker (14). In the invention, the actuating rocker (20) rests on a hydraulic lash adjuster (24). A control spring (136) is provided to urge the summation rocker (14) in a direction to compress the hydraulic lash adjuster (24). A stop (138) associated with the control spring (136) limits the movement of the summation rocker (14) towards the lash adjuster (24) so as to set the clearance in the valve system when the valve (22) is closed and the cam followers (16,18) are on the base circles of the two cams (10,12).

摘要： Apparatus and method are disclosed for converting an internal combustion engine from a normal engine operation (20) to an engine braking (or retarding) operation (10). The engine has an exhaust valve train containing two exhaust valves (300), a valve bridge (400) and an exhaust valve lifter (200). The apparatus has an actuation means (100) including a hydraulic system integrated into the exhaust valve train. The hydraulic system contains a braking piston (160) slidably disposed in the valve bridge between an inoperative position (0) and an operative position (1). In the inoperative position, the braking piston is retracted and the actuation means disengaged from the normal engine operation. In the operative position, the hydraulic piston is extended and the actuation means opens one of the two exhaust valves (300a) for the engine braking operation. The apparatus also includes engine brake reset means (150) for modifying the valve lift profile generated by the enlarged normal cam lobe (220) when the small braking cam lobes (232) and (233) are integrated into the normal exhaust cam (230). The apparatus also has a control means (50) for moving the actuation means between the inoperative position and the operative position.

摘要： The invention relates to a valve control for actuating at least one valve, especially an inlet or outlet valve of an internal combustion engine, wherein the dimension of the valve lift of the at least one valve corresponds to a superposition of two cam profiles which can be adjusted in phases in relation to each other and are displaced synchronously. The aim of the invention is to improve the construction and functioning of the valve control. As a result, a guiding means between an intermediate element and the first cam profile is embodied as third cam profile which is formed in a complementary manner with respect to the first cam profile and rotates in a synchronous manner therewith.

摘要： A mechanism for actuating an engine poppet valve includes two rotatable cams, a first rocker mounted on a pivot shaft and acting between a first of the two cams and the stem of the valve, and a second rocker mounted for rotation about a fixed axis and acting between the second of the two cams and the pivot shaft of the first rocker to raise and lower the pivot axis of the first rocker cyclically in synchronism with the rotation of the second cam, whereby the valve is operated in dependence upon the instantaneous sum of the lifts of the two cams. In the invention, an element of the valve actuating mechanism transmitting force from one of the cams to the valve stem is formed in two parts, one part movable by the associated cam and the other transmitting force to the valve stem, and a latching mechanism is provided for selectively locking the two parts of the element for movement in unison with one another and disconnecting the two parts of the element from one another to inhibit transmission of force from the associated cam to the valve stem. The latching mechanism is such that a change of state from locked to disconnected and vice versa can only take place when at least one of the two rockers is at or near the base circle of the associated cam and the change of state is initiated by the movement of the rocker system whilst the poppet valve is closed.
