DEVICE FOR THE VARIABLE CONTROL OF AT LEAST ONE VALVE, FOR EXAMPLE FOR A RECIPROCATING ENGINE
Abstract:
A device for controlling at least one valve, the device comprising a body having a non-deformable cavity communicating exclusively with the outside via at least four rectilinear cylinders that are closed respectively by an opening piston (P1) actuated by an opening cam (C1), a closing piston (P2) actuated by a closing cam (C2), a shuttle piston (Pa) serving to load or unload the device, and a piston (Ps) that is mechanically connected to the valve. By adjusting the angular phase shift between the opening and closing cams (C1, C2), the control device of the invention makes it possible in operation to adjust the lift of the valve, the angular duration of the opening of the valve, and if necessary, to deactivate the valve completely throughout the duration of a cycle.
Abstract(Chinese):

一种用于控制至少一个阀的装置，该装置包括具有不可变形的空腔的主体，该主体经由至少四个直线气缸，其通过由打开凸轮（C1）驱动的打开活塞（P1）分别关闭， ，由关闭凸轮（C2）致动的关闭活塞（P2），用于装载或卸载装置的往复活塞（Pa）以及机械地连接到阀的活塞（Ps）。 通过调整开闭凸轮（C1，C2）之间的角度相移，本发明的控制装置使得可以在操作中调整阀的升程，阀的开度的角度持续时间，并且如果需要 ，在整个循环的持续时间内完全禁用阀门。
