摘要： A rocker arm comprising a supply path that communicates with a first lash bore and a first spool bore. A spool is in the spool bore. A hydraulic lash device is in the first lash bore, wherein an outer body is configured to collapse during a first valve lift profile when receiving a low pressure fluid, and wherein the outer body and the inner body are configured to cooperate rigidly when receiving a high pressure fluid during a second valve lift profile. The spool is movable to a first spool position to align the spool notch with a first spool path and a second spool path, and the spool is movable to a second spool position to align the spool notch with the second spool path and an accumulator path. The supply path in to the rocker arm is the only source of fluid to the spool.

摘要： A system for variable actuation of an engine valve of an internalcombustion engine comprises a master piston (16) driven directly or indirectly by a cam (14) of a camshaft (11). A slave piston (21) is driven by said master piston (16) by means of a volume of pressurized fluid (C) interposed between the master piston (16) and the slave piston (21). The slave piston (21) causes the engine valve (7) to open, against the action of a spring (9). An electrically operated control valve (24) controls a communication between the volume of pressurized fluid (C) and an environment at lower pressure (23), with which a fluid accumulator (270) is in communication. An electronic control unit (25) is programmed for controlling the electrically operated control valve (24), so as to actuate the engine valve (7), depending upon the operating conditions, according to one or more different valve modes, including a late-valve-opening (LVO) mode and/or a multilift (ML) valve mode. When one of these valve modes is actuated, the control valve (24) opens the aforesaid communication in advance with respect to the end of the lift cycle of the cam (14), and not after closing of the engine valve (7), in such a way as to prevent or reduce a decrease in pressure in the volume of pressurized fluid (C) after closing of the engine valve (7).

摘要： A valve opening/closing timing control device capable of quickly determining attainment of an intermediate locked phase includes: an intermediate lock mechanism capable of switching between a locked state in which a lock member provided in a drive-side rotary member protrudes and fits into a recess provided in a driven-side rotary member, thereby constraining a relative rotation phase to an intermediate locked phase, and an unlocked state in which the lock member withdraws from the recess, thereby releasing the constraint; a phase control unit that controls supply of a fluid to a retard chamber and discharge of the fluid from an advance chamber, or controls discharge of the fluid from the retard chamber and supply of the fluid to the advance chamber, such that the lock member attains the intermediate locked phase; and a determination unit that determines whether the lock member will attain the determination phase, when control has been performed such that the lock member moves toward a determination phase that has been set at a different position than the intermediate locked phase in the recess, after execution of control to supply the fluid to the retard chamber and discharge the fluid from the advance chamber, or control to discharge the fluid from the retard chamber and supply the fluid to the advance chamber. When the result of that determination is that the lock member will not attain the determination phase, the determination unit determines that the relative rotation phase is in the locked state.

摘要： A lash adjuster includes a body (11), a plunger (12) inserted into the body (11) and a partitioning member (13, 13A) inserted into the plunger (12). The plunger (12) has a bottom wall (18) with a valve hole (20) and a peripheral wall (19) having an oil passage hole (26). The plunger (12) defines a high-pressure chamber (22) between the bottom wall (18) and the body (11). The partitioning member (13, 13A) has a plate-like baffle (39) located opposite the passage hole (26). The baffle (39) has an upper end serving as an oil passage end (33) located above the passage hole (26). The plunger (12) has interior divided into two spaces by the baffle (39). The passage hole (26) is located at one space side. An oil passage (40) is defined at one space side. A low-pressure chamber (23) is defined at the other space side to store hydraulic fluid flowing through the passage hole (26), the oil passage (40) and the passage end (33). The low-pressure chamber (23) supplies the fluid through the valve hole (20) into the high-pressure chamber (22).

摘要： An actuator for axially displacing an object includes an actuator piston disc and an actuator piston rod, which together form an actuator piston, a cylinder volume, the actuator piston disc dividing the cylinder volume into a first part and second part and being displaceable in the cylinder volume between an inactive and active position, a pressure fluid circuit arranged for controllable fluid communication with the first part, and a first hydraulic circuit including a liquid-filled space, the actuator piston rod being disposed to be axially displaced in relation to the liquid-filled space in connection with axial displacement of the actuator piston disc in the cylinder volume. The actuator piston includes a second hydraulic circuit, the liquid-filled space being in fluid communication with an inner cavity in the second hydraulic circuit when the actuator piston disc is in the inactive position, the inner cavity partly being delimited by a positioning piston.
