摘要： Described is an apparatus for rapid pressure buildup in a motor vehicle reservoir-type injection system (common rail) supplied with fuel by a high-pressure pump, the apparatus including a piston, which defines a pressure chamber that can be enlarged counter to the force of a spring element prestressed counter to the piston, which pressure chamber communicates with the feed pump and with the device supplied with the pressure medium. A locking device acting on the piston is provided, by which the piston can be locked in a locking position, assumed as a result of the pressure, built up in the pressure chamber by the feed pump, counter to the prestressing of the spring element and can be untensed after unlocking into a position that reduces the size of the pressure chamber. By the relaxation of the spring, the system pressure is built up suddenly.

摘要： A connection between two shaft ends situated coaxially one behind the other, of a gas exchange valve of an internal combustion engine and a piston rod of a valve actuator is provided, where at least one coupling member at least partially surrounds the shaft ends. The coupling member is radially compressed with respect to the two shaft ends by at least one compressing member to produce static friction locking between each shaft end and the coupling member that transfers the actuating motion of valve actuator to gas exchange valve in a slip-free manner. As a result, the fatigue strength of the connection may be increased and its assembly and disassembly may be simplified.

摘要： A device for controlling a gas exchange valve for internal combustion engines, having a housing including an axially movable valve member, which on an end close to the combustion chamber, has a valve sealing face that cooperates with a valve seat affixed to the housing and on an end remote from the combustion chamber, has a piston that axially separates upper and lower hydraulic working chambers from each other. The lower working chamber closer to the combustion chamber acts on the valve member in the closing direction and the upper working chamber further from the combustion chamber acts on the valve member in the opening direction. The lower working chamber continuously communicates with a high pressure source and the upper working chamber can be alternatingly filled with high pressure by way of a high pressure supply line containing an electric control valve. The upper working chamber is discharged by way of a discharge line that contains an electric control valve. When the electric control valve is without current, the control valve closes the high pressure supply line connected with the upper working chamber and when the electric valve in the discharge line is without current, the discharge line is open.

摘要： A system for controlling a gas exchange valve for internal combustion engines, comprising a movable valve member in a housing which, on an end close to the combustion chamber, has a valve sealing face that cooperate with a valve seat in order to control an inlet or outlet cross section at the combustion chamber of the engine. On an end remote from the combustion chamber a working piston defines at least one hydraulic working chamber, whose alternating filling and discharging with a pressure fluid can be used to move the valve member in the opening and closing direction. The supply pressure of the pressure fluid supplied for the actuation of the gas exchange valve member is adjusted step wise as a function of current operating parameters of the engine.

摘要： A hydraulic actuator for gas exchange valves of internal combustion engines is disclosed, in which the lifting of the gas exchange valve from the valve seat is effected with great force. The opening motion of the gas exchange valve then ensues at reduced force. Upon closure of the gas exchange valve, the gas exchange valve is braked before striking the valve seat, so that operation of the gas exchange valve with little wear and little noise can be achieved.

摘要： An hydraulically controlled actuator for activating a valve, especially for activating a gas-exchange valve in a combustion cylinder of an internal combustion engine, which includes two fluid-filled pressure chambers having controllable chamber volumes and a movable operating piston which delimits the pressure chambers by piston sides facing away from one another, the operating piston acting upon the valve and having an effective closing area acted upon by fluid pressure in the pressure chambers to close the valve and an effective opening area acted upon by the fluid pressure to open the valve. To influence the kinematics of the opening and closing movement of the valve, the operating piston is such that the surface area of at least one of the two effective areas changes along the sliding path of the operating piston.

摘要： A method for simulating control functions of a control device, in which a control program code for execution of control functions is stored in a first memory area of a memory belonging to the control device, the control program code including one or more control program code modules for the control functions, and containing at least one switching device for switching over from a control program code module SPCM to a simulation program code module. At least one simulation program code module for one or more test control functions is made available in a second memory area of the memory. The switching devices switch over from the control program code module to a pertinent simulation program code module stored in the second memory area. The control program code is then processed, the simulation program code module being executed, via the switched-over switching device, instead of the control program code module.
